TS-4 Heating and Cooling Stages for Microscopes |

Above: TS4-Thermal Stage
With the TS-4 Thermal Stage, a specimen
on a microscope slide or dish can be maintained at any temperature
between - 20 degrees C and + 100 degrees C. Set-up is quick and easy ,
and the controller will regulate the stage temperature to within +
0.1degrees C.
TS-4 is a thermoelectric (Peltier) device and has no moving parts. No
liquid CO2, or nitrogen is used for cooling. Only AC current and a
trickle of running water are needed for operation. Two versions are
available:
- TS-4, range - 20 degrees to + 60 degrees C
- TS-4ER, range - 20 degrees to + 100 degrees C
The stage is a thin, nickel coated copper plate, with a thermoelectric module mounted on one side (see diagram below). 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 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 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 10 Amps at approx 5 volts DC for the thermoelectric modules in the stage. Output polarity is automatically reversed when the stage requires a change from heating and cooling, or vice versa. During set-up the digital display indicates the control temperature being selected. The actual stage temperature is displayed during operation. The thermometer circuitry in the TS-4 can also be used as an independent instrument, either with the microprobe supplied or with any type T thermocouple sensor. A switch on the front panel allows easy selection of the external sensor. Range of the thermometer is - 100° to +200°C. A thermocouple microprobe is supplied with the TS-4.
The pump and tank unit 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.

Custom Thermal Stages
TS-4SPD - SMALL
PETRI DISH STAGE Designed to accomodate a 35mm petri dish. Collar may be removed for temperature controlled slide applications. RANGE: TS-4SPD ( -15 TO +60 degrees C) |
TS-4LPD - LARGE
PETRI DISH STAGE Designed to accomodate a 60mm or 100mm petri dish. RANGE: TS-4LPD (-5 TO 60 degrees C) |
TS-4DIAPHOT -
NIKON DIAPHOT STAGE Designed for the Nikon Diaphot Microscope. Replaces central ring on the Diaphot microscope. Stage is no more then 1mm thicker than ring it replaces. The plate is countersunk for objective clearance. (model also available to fit Olympus IMT) RANGE: TS-4DIAPHOT (-5 to +60 degrees C) |
TS-4LV - LIECA
LABOVERT STAGE Custom micro-injection chamber - may also be used with slides or cover slips using adaptor ring. RANGE: TS-4LV (-15 to +60 degrees C) |
Custom thermal stages are now made for many applications and/or specific microscopes. These devices can maintain stage and specimen temperature anywhere between -20 degrees C and +100 degrees C (depending on model). The custom stages are made to user's specifications and can be a simple modification of the standard TS-,4 stage or a completely new configuration. Both upright and inverted microscopes can be accommodated. The standard stage is designed for use with glass slides or cover slips. The TS-,4 thermoelectric controller is easy to operate. Simple controls on the front panel allow the user to adjust temperature which is continuously displayed on the digital readout. The unit is accurate to 0.I°C and requires only a trickle of running water for continuous operation. Above are photographs of some of our custom stages. Please contact us to discuss you specific needs. |
