• These specifications apply to each heating element.
• Two Hirose cables are included with the reference cell heater for direct connection to the two output channels of the TC300 Controller.

• Compatible with Ø25 mm Glass Cells
• Adapters for Ø9 mm or Ø19 mm Glass Cells
• 15 W Heating Power per Element (Two Elements per Assembly) with Thermistor
• Incorporates Hirose Connectors and Includes Cables for Use with TC300 Heater Temperature Controller
• 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.

Thorlabs' TC300 Heater Temperature Controller (sold separately) is the ideal controller to maintain the heater temperature. Each heater ships with two Hirose cables to directly connect to the two output channels of the temperature controller. The two output channels allow for full operation of the reference cell heater using only one controller.

• Note that this is the typical maximum achievable without insulation. The absolute maximum temperature above which the part should not be raised is 90 °C.
• One TC200CAB10 Hirose cable (sold separately) is necessary per heater for compatibility with the TC300 Heater Temperature Controller.

• Compatible with Ø25 mm Glass Cells
• Clear Aperture: 0.79" (20.0 mm)
• 10 W Heating Power with Thermistor
• Mounts Using Nylon-Tipped Setscrew with 5/64" (2.0 mm) Hex

The GCH25R cap heater is designed for use with Ø25 mm glass cells. It incorporates a 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. A TC200CAB10 Hirose cable can be used to connect a GCH25R heater to the TC300 Heater Temperature Controller (each sold separately). For this purpose, the Hirose cable must be cut and wires exposed.

SM1L10 Lens Tube with HT10K Foil Heater

• 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 for Use with TC300 HeaterTemperature Controller

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 and 10 kΩ negative temperature coefficient (NTC) thermistor.

The HT10K features bare wire leads for use with a user-provided connector. Alternatively, the TLK-H connects to the TC300 Heater Temperature Controller using our TC200CAB10 6-Pin Hirose Cable (sold separately), eliminating the need to wire the foil heater into the controller.

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.
