The AirTherm™ SMT is a new generation of heat control system from WPI designed to be used in Live Cell Imaging applications with microscopes fitted with a full microscope environmental chamber enclosure. The standard AirTherm™ SMT controls temperature and, as an option, monitors humidity.

PID algorithm for maintaining tight control

The AirTherm™ SMT uses a PID control algorithm to tightly control the temperature and monitor humidity of the controlled environment

With AirTherm™ SMT, the temperature of the sample and microscope optics can be controlled to within 0.2°C. During operation, air is drawn out of the chamber through a flexible hose, heated by the AirTherm™ SMT heater and re-circulated to the chamber by the return hose.

Ready to connect to your microscope chamber

The system is typically used in a closed loop configuration.

The AirTherm™ SMT system includes:

  • Two coil-reinforced heater hose pieces and hose clamps (single inlet, single outlet hoses and clamps kit).
  • Optional hose kits for dual inlet, dual outlet chambers.
  • Temperature sensor for remote placement in environmental chamber.
  • Optional Humidity probe for monitoring chamber humidity.
  • Optional ultrasonic humidity kit with ultrasonic humidifier, mixing “T” and connecting hoses (Humidity probe required).

Glass bottom dishes

For high numerical aperture (NA) live-cell imaging, cells must be plated on glass (e.g., WPI’s FluoroDish Glass Bottom Dishes, spotting 0.17 mm glass thickness) or standard cover slips. Since cover slips inherit other problems associated with sterility and accidental damage to expensive microscope condensers, WPI designed new and improved glass bottom dishes (35 mm x 10 mm or 35 mm X 22 mm) that are not cytotoxic. A special adhesive in conjunction with an advanced dish design makes the FluoroDish the only non-cytotoxic glass dish in the world. This means that cells can actually be cultured for 4 to 5 days in the same dish and then carry the complete cell culture with media from the incubator directly into the (Air-Therm controlled) recording chamber. This is a comfort level that hitherto was unattainable by scientists and clinical researchers since cells will have to be transported from the culture dishes on to cover slips just prior to imagery or attaching patch electrodes.

Chamber

The most problematic aspect of any live cell imaging procedure or patch clamp approach is the thermal drift of high magnification lenses caused by temperature fluctuations in the microscope's environment. It is necessary to constantly readjust the focus during image acquisition due to this thermal-drift, introducing artifacts during quantitative microscopy due to the photo-bleaching that occurs during refocusing. The optimal solution to this problem is to use WPI’s Air-Therm temperature controller connected to a Plexiglas or acrylic chamber that encloses the entire imaging area (or at least the objectives and the stage). Using such a chamber will result in highly stable temperature control and minimal thermal drift.
