TS-4MP Thermal Microscope Stage
  • Holds specimen at any temperature, -20° to +100°C

  • Digital display of set-up and operating temperatures

  • Control to within 0.1°C

  • Fits most microscopes

  • Built in digital thermometer and probe

With our TS-4MPER Thermal Stage, a specimen on a microscope slide or culture dish can be maintained at any temperature between -20°C and +100°C. Setup is easy, takes little time, and the controller will regulate the stage temperature to within +/-0.1°C

TS-4MP is a thermoelectric (Peltier) device and has no moving parts.  No CO2 or liquid nitrogen is used for cooling.  Only the AC Current and a trickle of water are needed for  operation. Two versions are available

Range:    TS-4MP -20° to +60°C
                 TS-4MPER -20° to +100°C

 The TS-4MP consists of a stage, a controller and an optional pump unit:

The Stage is nickel-plated copper, with a thermoelectric module mounted on one side (see diagram). The plastic base is the same size and thickness as a glass slide and fits onto the mechanical stage of the microscope in the same manner as a slide.  The thermal stage can therefore be moved relative to the optics by the normal mechanical stage controls.  A hole in the metal plate permits the use of transmitted light.

Water is required for removal of excess heat generated by Peltier cooling from the stage.  The two water tubes have self-sealing connections to prevent spills.  Running water from a tap can be used. If tap water is not easily accessible, our pump and tank unit, the PTU-3 (see page 21), is compact and convenient.

Sensors mounted in the stage provide temperature monitoring for control purposes and for safety.  The safety sensors prevent overheating in case of failure of cooling water supply or other malfunction.

The Controller produces a maximum of 10Amps at approximately 5 volts DC of the thermoelectric modules in the stage. Output polarity is automatically reversed when the stage requires a change from heating to cooling, or vice versa. During adjustment of the desired temperature, the SV digital display indicates the control temperature selected while the PV display reads the actual temperature.

The thermometer circuitry in the TS-4MP can also be used as an independent thermometer, either with the microprobe supplied or with any other Type T thermocouple sensor.  A separate thermocouple microprobe is supplied with the TS-4. 

The optional pump and tank unit (PTU-3, see page 21) is connected to an auxiliary AC output on the back of the controller.  The tank provides sufficient circulation to keep the stage cooled.  All water connections are self-sealing.
Using the TS-4MP

The standard TS-4 thermal stage fits easily onto most microscopes and is adjusted with the mechanical stage controls. There are spring clips on the surface which can be used to hold a glass slide in position on the thermal Stage. The controller has two displays. The control temperature can be adjusted by the buttons on the front of the controller. Temperature selection is indicated on the SV digital display. The actual temperature is indicated on the PV display.
