TC-09D_TemperatureController_forDualChamber_web_016v1.jpg

Temperature Controller for Dual Chamber

Our temperature controllers feature unsurpassed thermoregulatory performance. A novel control algorithm results in quicker time to reach setpoint (6–10 min, from 22 ºC to 37 ºC). Our temperature controllers now feature analog outputs that produce signals compatible with most data acquisition systems. The TC-09D has two heating controllers that can be used to regulate the bath temperature in the two baths of our CH-2 vessel chambers independently. The thermostat control can also be disabled, allowing the TC-09D to be used as a temperature monitoring and recording device (when using the analog output). Panel controls allow for regulating the bath temperature of both chambers, chamber 1 only, chamber 2 only, or monitor only (no temperature control).

The TC-09D is designed to control the bath temperature in our CH-2 dual vessel chambers under steady-state conditions, when bath superfusion is not used. This is particularly useful when you have a stagnant bath with a HEPES or MOPS buffered saline solution. The temperature controller is not able to regulate bath temperature in the presence of bath superfusion. In that case, it is preferable to use a heat exchanger in your superfusion line to warm the bath saline just before it enters the vessel bath.

Specifications
Power120 V or 220 V
Control limitsambient to 50 ºC
Accuracy±1 ºC
Time to reach 37 ºC (from 22 ºC)6–10 min
Analog output10 mV/0.1 ºC

TC-09S_TempController_SingleChamber_web_010v1.jpg

Temperature Controller for Single Chamber

Our temperature controllers feature unsurpassed thermoregulatory performance. A novel control algorithm results in quicker time to reach setpoint (6–10 min, from 22 ºC to 37 ºC). Our temperature controllers now feature analog outputs that produce signals compatible with most data acquisition systems. The thermostat control can also be disabled, allowing the TC-09S to be used as a temperature monitoring and recording device (using the analog output).

The TC-09S is designed to control the bath temperature in our CH-1 single vessel chambers under steady-state conditions, when bath superfusion is not used. This is particularly useful when you have a stagnant bath with a HEPES or MOPS buffered saline solution. The temperature controller is not able to regulate bath temperature in the presence of bath superfusion. In that case, it is preferable to use a heat exchanger in your superfusion line to warm the bath saline just before it enters the vessel bath.

TH-M_ThermistorTemperatureMeter_web_051v1.jpgThermistor Temperature Meter

This meter provides a display of the temperature sensed by any of our thermistor temperature sensors. The THS-TEE sensor plugs directly into the TH-M meter. If you would like to monitor the temperature in one of our vessel baths using the THRS sensor a special cable is also required.  Actual meter may vary due to supplier variations.

GHE_GlassHeatExchanger_web_1890v1.jpgGlass Heat Exchanger
Our precision blown glass heat exchangers allow warming of vessel bath superfusate solutions. A water circulator pump is plumbed to the water jacket, and the superfusate is plumbed directly to the heat exchanger coil. Warmed superfusate coming out of the heat exchanger can be delivered directly to the vessel bath. These heat exchangers are also versatile pieces of lab equipment, and they can be used in any application requiring warming (or cooling with appropriate temperature controller) of fluid solutions. The heat exchanger is designed to pack the maximum number of coils in the minimum amount of space. This ensures
optimal heat exchange, which minimizes problems associated with maintaining pH levels in physiological buffers.

Thermistor Replacement Sensor

Our miniature temperature sensors are designed to be chemically inert, produce very little fluid displacement, and occupy little space in the vessel bath. Includes clip and screw for mounting the thermistor onto the base of your chamber.

THS-TEE_InlineTeeThermistorSensor_web_043v1.jpgThermistor Sensor, Inline Tee

This convenient assembly incorporates our miniature temperature sensor into a T so that it can be placed in-line into a flow path. This temperature sensor is ideal for measuring temperature in the inflow or outflow lines of the vessel bath, or for any application for which in-line temperature measurement is necessary. The ports on the tee are female luer-style.
