Cooling Probe
Operating temperatures below ambient can be achieved by using the cooling
probe with a chilled water circulator. The cooling probe is supplied as an
accessory and can be used in an insert with a 3/8" or 10mm hole (see
Accessories). Instructions for its use are included with the probe.
The block should not be operated at temperatures below dewpoint as
excessive build up of moisture will occur which may cause damage to the
interior of the unit.
After Use
1.
When you have finished heating samples, remember that parts of the
unit – inserts and associated accessories – may be very hot. Take the
precautions listed earlier. We recommend that the inserts should be
allowed to cool to 70°C before being removed from the Tecal unit.
They will still have to be handled with care
2.
If you need to remove an insert while it is hot, fit the extractor tool into
the locating holes and lift the insert out carefully. Never leave the
extractor tool in the insert while it is being used in the Tecal unit.
