"I'm very pleased with our microscope heating system from Digital Pixel. At our facility we are routinely running
72 h+ long time lapse experiments on primary cells without any issues with it.
What really sets the system apart from any other that I have been working with over the past 10 years, is that it is completely silent.
As any microscopist knows, the heating system is often the loudest component in a live cell microscopy setup.
Because the microscope room is my main working environment, I find it quite pleasant, and probably good for my hearing in the long run,
not have the constant noise of a loud convection fan in my ear."

"Fluorescence lifetime image of mitochondria-targeted fluorescent molecular rotors in human epithelial corneal (HCE) cells at 37 degrees C and 5% 2. The false colour scale represents the fluorescence lifetime from 1.79ns (red) to 2.59ns (blue). A representative fluorescence decay is shown on the right.

We use a Microscope_Heaters Heated Insert and CO2 Controller system to study fluorescent molecular rotor dyes in living cells.[1] These dyes are based on bodipys, and change their fluorescent lifetime as a function of viscosity. Fluorescence lifetime imaging (FLIM) of them allows us to get images of viscosity in cells. We have used fluorescent molecular rotors targeted to mitochondria in human epithelial corneal (HCE) cells at 37 degrees C, which reveals a variability of mitochondria viscosity in livings cells under these conditions.[2]

The Heated Insert and CO2 Controller system from Microscope_Heaters is great, as it is small, reliable and portable, so we are easily able to move it across several microscope platforms. Performance and company support in optimizing the system has been excellent. We would highly recommend this system to any researchers using live cell imaging."

Zeiss Inverted Microscope Incubation Systems
Digital Pixel design and manufacture a range of incubation systems for Zeiss inverted microscopes. Our vibration free heater systems provide the ultimate in system thermal homogeneity and stability. Systems are available for use with the Zeiss wide field, as well as the Zeiss 780 and 880 Confocal systems. The system stability of the Elyra Super Resolution Microscope can be enhanced by using our heaters to gently warm the system to 22 oC.
SuperSealTM System
Designed for researchers at the University of Heidelberg, the application demanded that full access to a multi well dish was required, in order to add a drug when certain points in the cell cycle were reached. However full CO2 control in the sample area is essential to maintaining cell viability. Our unique Enhanced Sealing Technology provides CO2 control within the whole incubation.

Zeiss 780 Confocal   Grenoble, France

Great Ergonomics
The top of the incubation is directly connected to the transmitted light column of the Zeiss inverted systems, so getting access to the sample area is simple and easy. Removable panels provide easy access to cameras and other peripherals. The incubation is directly supported on the microscope, thus providing uninterrupted clear space around the microscope for system peripherals, beam splitters, multiple camera configurations etc.
Extended Temperature Range - Great Thermal Homogeneity
Our advanced heater technology removes conventional system limitations, by providing temperature control even close to ambient temperature. This makes the system ideal for multiple applications including Xenopus, Zebrafish and Drosophila studies, and of course mammalian studies. Our dual heater systems gently warm your sample area from both sides reducing and eliminating thermal gradients.
Thermal Control for Enhanced System Stability
The extended temperature range of Digital Pixel heater systems allows them to be used to stabilise microscope systems such as the Elyra Super Resolution Microscope can be enhanced by using our heaters to by gently warming the system to 22 oC.
Multiple System Configurations
Systems are available in either matt black (MB), clear (CL) or MB/CL, which is matt black with a clear front and blackout curtain. Zeiss systems are also available with our SuperSeal option (SUPSEAL).
Supported Microscopes
Zeiss 200M

Temperature Range Ambient +1 oC to 42 oC
Temperature Stability ± 0.3 oC
Temperature Homogeneity ± 0.3 oC across the XY axis of a motorised stage system.
All measurements depend on the precise microscope and incubation system configuration, but are typical.
Leica Inverted Microscope Incubation Systems
Digital Pixel support both the current Leica DMi8 as well as the DMi6000 range of inverted microscopes in wide field, as well as configurations compatible with the Leica SP5 and SP8 confocal systems.
Leica DMi8 Incubation Systems Variants
We have developed three designs based on customer requirements for the DMi8 microscope.Two of our designs go to the optical table, one is mounted directly onto the microscope.

Leica DMi8 SP8 Confocal   Southampton, England

Of the two designs that are table mounted, one is designed to allow the researcher greater access to the microscope by removing the main front panel of the incubation system. This is typically used in Super Resolution configurations. These systems have been designed to allow full access to the microscope controls without having to move any silicon flaps or open any doors, through the use of an internal panel.
The microscope mounted system is normally used either for wide field or spinning disk systems. Here, the emphasis is on keeping clear space around the base of the microscope for peripherals such as cameras, beam splitters etc. The Digital Pixel Solution is mounted directly on the microscope, and does not require support poles. Combined with our internal heater technology this approach is the easiest to install system on the market.
Multiple System Configurations
The three system confugurations are available in either matt black (MB), clear (CL) or MB/CL, which is matt black with a clear front and blackout curtain.

Digital Pixel have designed bespoke incubation systems compatible with a range of third party microscope equipment and microscope systems. Below is a list of some of the systems we have supported.
Andor Spinning Disk System
Digital Pixel have designed incubation systems upgrades to accommodate the new Andor CSU-11 spinning disk head

Andor Spinning Disk and Nikon Ti-E   ENS Paris

Perkin Elmer Spinning Disk System
Compatible with the various Perkin Elmer systems out Incubation, provide easy access to the scanning head and system peripeherals.
Crest Spinning Disk System
The latest addition to our range our CREST spinning disk incubation systems is microscope mounted proving great access to system components.
Witec Raman and AFM Microscope
Combines an Upright and Inverted microscope system on the same chassis. These systems are sometimes combined with AFM systems our vibration free heater systems are invaluable in this application area.
Abberior STED Microscope System
Digital Pixel have designed a vibration free incubation system for this system using an Olympus IX83 as the microscope platform. The incubation system allows the user to access the STED optics for system adjustment without having to remove the incubation system.
Stage Top Heater Solutions
All systems include independent temperature control over the insert and the glass top of the insert, and are sealed to maintain gas control. Combination systems are available with CO2 and CO2 -O2 controllers. Systems normally accept a 3mm OD flexible tube for gas delivery- other options are available.

Heated Insert ASI Stage   Birmingham, England

Open Heated Inserts
Designed for applications such as patch clamp or perfusion studies where access to the sample is essential, this system boasts a dual temperature control configuration. It controls the temperature of the heated insert, and optionally controls the temperature of media entering the sample area.
Intravital Microscopy Imaging System
Designed for whole animal viability during extended imaging experiments the system boasts two independent temperature control channels. The first controls a heated insert, the second a heated blanket. Combined with a third independent temperature monitoring system, this solution has been shown time and time again to provide the best results. Compatible with a wide range of motorised microscopes, this system is used on many two-photon experimental systems.
A removable insert in the heating assembly, and titanium windows completes the system solution.
CO2 Gas Controller Systems
A wide variety of cell systems, require a closely controlled CO2 concentration to maintain cell viability over extended periods. While it is possible to use 5% CO2 cylinders, these are expensive, bulky and provide limited flexibility in terms of the CO2 concentration range possible. Put simply 5% CO2 concentration at the cylinder does not guarantee the optimum outcome for your cells. Furthermore the use of flow based mixing systems, while a little less expensive provide far from consistent gas concentrations.
There are three options in the Digital Pixel range of CO2 controllers, designed to meet the needs of a single microscope system, or those of a Core Microscope Facility, and finally for use with our SuperSealTM enhanced sealed incubation system. System installation is easy. Digital Pixel CO2 controllers only require 100% CO2. Additional gas supplies such as air or N2 are not necessary.
DP_2000_CO2_CORE
This system is designed to meet the CO2 requirements of several microscope systems. It has an enhanced pumping system, and is supplied with 6mm OD tubing and flow controllers to supply up to three microscopes, provided the total flow distance is less than 15 meters. The flow rate can be controlled internally over four flow setting using a simple rate dial. The easy to use front panel shows the CO2 CONC SET, and the CO2 CONC ACTUAL. The range of the system is 0.1-20%.
DP_2000_CO2_STD
Designed to meet the CO2 requirements of a single microscope system, it features a long life internal pump. Again the flow Rate can be controlled, with four flow setting including OFF without turning the controller OFF. This feature means you can be ready to go at any time. Again the CO2 concentration range is 0.1-20%. Optionally Relative Humidity Monitoring and control is also possible.
DP_2000_CO2_SUPSEAL
This system is designed to control the CO2 concentration within a whole incubation system. It must be used in conjunction with one of our SuperSealTM Incubation Systems. In this configuration CO2 is delivered directly into the sample area. CO2 concentration is measured close to the sample are. These systems are designed for applications requiring complete access to the sample, for example for the addition of a drug or other perturbing material during a time lapse experiment.
DP_2000_CO2_O2_SINGLE
Designed for hypoxia studies, this system measures CO2 and O2 concentration within the sample area. Microprocessor based technology maintains CO2 concentration in the range 0-8% range is 0.1-20% and O2 concentration in the range 21% to 1.0%. Direct measurement in the sample area provides clear and obvious benefits over measuring gas concentrations at a distance.
Features-
  • High Performance NIRD CO2 detector used to monitor concentration.
  • Long life pump provides excellent gas delivery.
  • Microprocessor controlled concentration levels- No Guess work
  • Only 100% CO2 gas supply required for full operation- No O2 or N2 required.
Sealed Inserts
As part of our gas controller range we have also designed a range of sealed inserts for industry standard motorised stages. Normal inserts are open and as a result cannot maintain when a desired CO2 concentration in the sample area.
Digital Pixel Sealed Inserts are designed to maintain CO2 concentration at the sample. Gas is introduced through a push/pull 3mm OD flexible tube fitting. This provides easy connectivity while minimising any tubing drag on the stage. A clear glass lid allows easy access to the sample. Our inserts accept multi well dishes, as well as slides and Petri dishes.
Is Vibration Free Operation Really So Important?
Is Vibration Free Operation Really So Important? Well an increasing number of scientists think so. Their experiments really demand it. For more demanding techniques, such as Super Resolution Microscopy, electrophysiology, tweezer experiments or simply using a x60 or x100 objective- the removal of this complication has obvious advantages!
On the other hand, in any kind of microscopy, it is really one less thing to worry about with numerous side benefits.
Better Focus Stability
Most fan based systems warm the sample area by blowing warm air into the environmental incubation system- once the system detects a drop in temperature. This method is a second order control mechanism relying on the system making an educated guess as to the power requirements of the heater, and then has to factor in the rate of air flow in the system. This leads to well documented oscillations in the temperature at the sample, which can result in reduced cell viability as well as increased focus drift.
Digital Pixel Heaters, on the other hand, gently warm the sample area from both sides and as a result reach a steady state equilibrium with a steady flow of heat into the sample area. The result better microscope stability- less focus drift!
How can I be sure that the temperature across my 96 well dish is constant?
The only way that we can think of is by gently warming the sample area from both sides, across the width of the sample area. Digital Pixel achieve this by using multiple heaters. In tests, the temperature measured from one edge of a typical 96 or 24 well dish is constant to within the accuracy of a P100 sensor! If you blow hot air across a sample area- the physics of the situation lead to thermal gradients across the sample area.
Wider Temperature Range- Is it Important?
Most Microscope Heater systems can only provide any thermal accuracy when the required temperature is 4-6oC above the ambient temperature. There is a minimum amount of heat that they can put into the system. Digital Pixel Heater systems confidently cope with anything from 1oC above ambient to up to 50oC depending on the system configuration. This allows a wider range of samples to be studied- especially important when you have invested heavily in the latest microscope technology. Especially important for Core Facilities.
Reliability Really Is Important!
Digital Pixel Heater Systems have no moving parts- no fans to break down – no air filters to replace. As a result, our new Gen II systems have in excess of 80 equipment years in the field without a systems failure - not one has broken down! This means much less down time on your time lapse system.
Cleaner Sample Environment
The introduction of external air that is then warmed before entering the incubation system –takes dirty air from outside the microscope environment- your samples are being constantly bombarded by possible contaminants. Our heating technology reduces the chances of sample contamination.
Summary
  • Vibration Free Operation- No fans required- Better Reliability
  • Internal Heaters – Reduced Sample Contamination- Reduced Optical Contamination
  • Dual Heaters – Reduced Temperature Gradients Enhanced Homogeneity Across the Sample
  • Wider Temperature Range- Ambient through to 45 oC- Wider Range of Samples Not Possible with other Systems.
  • Small Equipment Footprint- No Messy Tubes or Pipes
  • Large Area Incubation Available
  • Greener, Cleaner Technology -
    • Power Usage 60% less than fan based systems
    • Less dirty air, cleaner optics
