2.6 Safety instructions – operation
2.6.1 General
The operator of the Biometra TRIO must make sure before each commissioning that the
condition of the device including the safety equipment is sound.
The following has to be observed:
 Free access to the power switch on the back of the enclosure has to be ensured dur-
ing operation.
 The ventilation fittings at the rear of the device must be unobstructed and opera-
tional. Covered ventilation grilles or slits etc. may cause the device to break down or
may cause damage to it.
 The use of oil between the samples and the sample block is not necessary to achieve
an improved heat exchange. However, if you still want to use oil, you should use
mineral oil. Do not use silicone oil.
 Be careful to avoid crushing or pinching injuries when closing the device.
The Biometra TRIO may cause burns. The following has to be observed:
 The thermal block, the samples and the heated lid reach high temperatures. There is
a risk of burns during contact.
 Ensure that the lid is securely closed before starting the program! Do not touch the
heated lid!
 The rapid heating of the thermal block can cause liquids to boil explosively. Always
wear safety goggles during operation!
 Do not touch hot sample tubes or plates and do not open them or boiling liquid may
escape!
 Only use plates and tubes that are suitable for high temperatures (up to 100 °C), fit
well into the thermal block (no shaking) and whose lids seal tightly!
