USER MAINTENANCE
CLEANING YOUR TC-3000G
Before cleaning your unit, disconnect from the power supply and allow it to cool to below 50°C.
CLEANING YOUR BLOCK
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. Bibby Scientific Ltd 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.
HEATER BLOCK REMOVAL
Removing the block may expose the possibility of electric shock; disconnect the unit from the
mains and allow to cool below 50ºC before continuing. Remove the four screws on the underside
of the unit and drop the block/fan assembly down. Unplug the assembly from the wiring and remove the
assembly from the unit. Refitting the block/fan assembly is the reverse procedure; be careful of the wires
as you refit the block.
CLEANING YOUR CASE
The outer case of the TC-3000G can be cleaned with a cloth dipped in water or ethanol (50:50
methanol/water or 99:1 water/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 Bibby Scientific Ltd that the proposed method will not damage the equipment.
