2Recommended liquids:

When working at low temperatures always use a liquid suitable for the lowest temperature at which the unit is capable of achieving, see the list of recommended liquids below. When using a flow cooler up to 30oC in an enclosed circuit use the recommended liquid.

For the RU-500or FC-500units:

Temperature Liquid

-35 oC to 0 oC * 40% water 40% anti-freeze 20% alcohol For the RU-200or FC-200units:

Temperature Liquid

-20 oC to 30 oC * 50% water 50% anti-freeze.

*Warning: Above 0oC alcohol may evaporate from the liquid giving a health and safety hazard and also deteriorating the mix. Check with health and safety procedures before using above 0oC.

Above 30oC anti-freeze may give off dangerous fumes. Again check with health and safety procedures before using above 30oC.

There is no liquid which will cover the full range of working temperatures. The units are designed to work up to 40oC with occasional peaks to 100oC, see Precautionary Measures in the Operation section. However with the coil removed and a TU-20D or a TU-20C in the bath, the baths themselves are quite capable of going to 250oC.

3Hoses should be as short as possible and secured with clips.

4 The whole system should be insulated as much as possible.

5 DIP COOLERS

Set up a bath and thermoregulator as described in the operating book for the thermoregulator.

The coil support supplied with the Dip Cooler mounted on a stainless steel plate is used in place of the small cover on the bridge piece of a Techne Bath. Slip the coil support onto the coil and allow it to rest against the end of the flexible. Tighten the knurled black screw on the coil support to prevent the coil moving in the coil support, do not overtighten. Remove the blank cover on the bridge piece and lower the coil through the hole in the bridge. Fix the support securely to the bridge with the two knurled screws previously removed.
