Immersion Circulators

With free downloadable software available at techne.com

TU-20D and TE-10D

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 or digital set/ readout, high pump output and RS232 interface.
 
TE-10D - Stability ±0.01°C
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 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

* Refrigeration or cooling coil is required for below ambient cooling
Stability ±0.005°C

Unheated Baths

Designed to be used with any Techne (or any clip-on) thermoregulator, these baths incorporate attractive carrying handles for added safety.

The four smaller models have seam free stainless steel inners for easy cleaning. The largest bath, the B-48, is of welded construction.

All baths have stoved enamel steel outer cases and a bridge mounting plate. Insulated baths can be supplied to order.

Accessories

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.

Flat and Gabled Lids

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)

Cooling Coil

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)

Fluids for Liquid Baths
•Low Viscosity
• Improves bath uniformity and stability
• Enhanced heat-up and cool down rates
• Safe and non-toxic
• Convenient easy pour 5 gallon containers

Dip & Flow Coolers

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.

Floating Insulation

Floating Insulation

  • Plastic Balls Floating Insulation Instead of Rigid Covers
  • Reduce heat and evaporative losses
  • Stabilize bath temperatures
  • Minimize splashing, odors and fumes
  • Improve workplace environment
 
Flasks and other glassware can be removed from and returned to the bath with only a momentary disturbance of the blanketed surface. Bath temperature can be taken with ease and the floating blanket can improve the workplace environment by minimizing fumes, odors and splashing.
