Techne TC-4000 - Manual (Page 47)

USER MAINTENANCE
CLEANING YOUR TC-4000
Before cleaning your unit, disconnect from the power supply and allow to cool to below 50ºC. The
heating/cooling block, including wells and flat surfaces, should be cleaned regularly to ensure optimum
heat transfer to the samples. Always clean the block if there has been a spillage. Use a cloth or cotton
buds dipped in a fresh, 50:50 water/isopropanol solution and make sure that no deposits are left in the
wells.
In the case of radioactive spillages the heater block can be removed from the unit for more detailed
cleaning. Techne recommends that you use a proprietary cleaning agent and follow the manufacturer's
instructions. The heating/cooling block is made of aluminium, therefore an agent such as Neutracon
(from Decon Labs Ltd.), suitable for nonferrous metals should be used. However, remember that other
parts of the unit are made of ferrous materials and may be damaged by spillage onto them.
The case of the TC-4000 may be cleaned with a cloth dipped in water or ethanol (methanol or
formaldehyde can also be used). No part of the case or cover should be immersed in the solvents. Do not
use aggressive solvents such as acetone or abrasive cleaners.
Before using any cleaning or decontamination method except those recommended here, the responsible
person should check with Techne that the proposed method will not damage the equipment.
