| Immersion Circulators |
 |
|
| With free downloadable software available at techneusa.com |
| These circulators will convert your existing liquid bath or an unheated bath or container into a precision temperature controlled bath with an exceptional thermal performance and offer a full range of options such as external circulation, analog or digital set/ readout, high pump output and RS232 interface. |
|
| TE-10A - Stability ±0.01°C |
|
TE-10D - Stability ±0.01°C |
| The analog clip-on thermoregulator offers a temperature range of -20°C* to +95°C, covering most routine laboratory applications. A circulating pump with external circulation connections is standard, as is adjustable over-temperature cutout. |
This digital unit offers a temperature range of between -40°C *to +120°C. There is a digital temperature selector, circulating pump with external circulation connections, adjustable over-temperature cut-out and low liquid level cut-out. |
|
TU-20D
This top of the range model has additional features fitted as standard including: an audible alarm, cooling coil and RS232 port plus TechneWorks Software and lead. Software is a free download (at techneusa.com) and a RS232 cable is required. The temperature range is -40°C* to 200°C |
| |
TU-20HT
This model is designed for internally circulated baths, thus it is not capable of external pumping for re-circulation, but does include a PC software and has an operating temperature range capability of -40°C* to 250°C |
| Stability ±0.005°C |
| * Refrigeration or cooling coil is required for below ambient cooling |

 |
Flat and Gabled Lids
A wide range of flat and gabled lids are available to fit all sizes of constant temperature baths. These enclose the open bath to provide a safe working environment. They also reduce heat and evaporative losses. Gabled lids provide extra working headroom, and their pitched tops direct condensate back into the bath. |

Cooling Coil
Connected to the main water supply, the cooling coil helps maintain temperature when bath temperature is near ambient. It is recommended for use when the bath operating temperature is within 5°C of ambient. Water circulated through the coil should be at least 5°C cooler than the bath temperature. (Standard with 20-HT systems) |

Polypropylene Spheres
A ball blanket is an effective way of reducing evaporation and loss of heat from a water bath acting as effectively as a lid, providing instant access to the bath. (See "Floating Insulation" for other sizes) |
| |
Readout Thermometers
ASTM Thermometers are recommended for accurate measurement of the bath temperature. They clip to the outside of the immersion circulator. (Please refer to ASTM Thermometer section of catalog) |

|
When paired with an immersion circulator these baths are a complete refrigerated circulating system for open or closed applications for temperature ranges from -20°C to 100°C. 7 liter bath capacity.
Temperature control is by the thermoregulator (TE-10A/TE-10D), giving two different combinations. |

| Dip & Flow Coolers |
|
|
The Flow Coolers work in conjunction with either a Techne thermoregulator or circulating system, they continually extract heat from the bath fluid by means of the heat exchanger which is built into the unit.
The cooling head of the Techne Dip Coolers fit neatly and unobtrusively into the corner of the bath and can be secured with a specially designed mounting bracket. Even if cooling can be achieved by cold tap water, a dip cooler is recommended as it conserves water and is easier and more convenient to use. |
