- 15 W Heating Power per Element (Two Elements per Assembly) with Thermistor
- Incorporates Hirose Connectors
- Compatible with 30 mm Cage System
The GCH25-75 glass cell heater uses two built-in heating elements to raise the temperature of a vapor cell to as much as 50 °C (when room temperature is 25 °C; limited by the heater unit). The temperature is monitored using a Minco Thin Film Element sensor. Adapter rings for Ø9 mm and Ø19 mm cells are included. Without the use of adapters, the heater mounts Ø25 mm cells. This allows the heater to be used with our standard reference cells. The heater incorporates Ø6 mm cage rods and is compatible with our 30 mm cage system.
Each heater ships with two Hirose cables for use with temperature controllers. The auxiliary output allows for full operation of the reference cell heater using only one controller.

The GCH25R cap heater is designed for use with Ø25 mm glass cells. It incorporates our HT10KR metal ceramic heater, which is a 10 W ring-shaped heater with a 10 kΩ thermistor. The aluminum housing features a double bore with a nylon-tipped setscrew to hold it in place at the end of the cell. Two cap heaters (sold separately) may be used on opposite ends of the glass cell.
This heater features bare wire leads for use with a user-provided connector. The red leads of the heater are connected to the resistive heating element while the white leads are connected to the thermistor.

- 1" x 3" Heating Area for Use with Glass Cells or Lens Tubes
- Adhesive Backing for Easy Installation
- 10 W/in2 Heating Power with Integrated Thermistors
- TLK-H Heater Incorporates Hirose Connectors
These 1" x 3" (25.4 mm x 76.2 mm) foil heating elements are useful for many lab applications. They have an integrated thermistor for closed-loop temperature control and an acrylic pressure-sensitive adhesive backing for easy installation. Both models use the same Kapton (polyimide) heating element.
The HT10K features bare wire leads for use with a user-provided connector, while the TLK-H can be used with our TC200CAB10 6-Pin Hirose Cable (sold separately).
Both foil heaters are flexible for use in applications such as heating lens tubes, as shown in the photo to the right. In this application, the lens tube can be isolated from the rest of the system using a Thermally Insulating Adapter.
