MAINTENANCE

Cleaning, maintenance and repair of the thermal cycler

For safety reasons the device must be switched off and the mains plug pulled before cleaning is
carried out!
The surface of the thermal cycler can be wiped off with a damp cloth or ethanol. Do not use aggressive
or scouring cleaners or organic solvents for cleaning. The device must be protected from
aggressive chemicals. Make sure that no liquid penetrates into the interior of the device. If sample
liquids penetrate into the drill holes of the thermal cycler clean them immediately with mild soap
followed by distilled water. You can use mild disinfectants for decontamination.
Maintenance should be carried out regularly to detect possible technical failures.
The device may only be opened by a qualified specialist. Unauthorized work on the device voids the
warranty. All kinds of repairs may only be carried out by authorized persons using original replacement
parts.
The replacement of single components of the device must not be done by the user but exclusively by
authorized specialists. Therefore, the device must be sent to the manufacturer. The surface of the
device should be decontaminated with a lint free cloth soaked with 70 % ethanol before sending.
The drill holes of the thermoblock shall be cleaned with a 1.5 % hypochlorite solution with the help of
a cotton bud. Please fill in and sign the decontamination certificate and send it to the manufacturer
together with the device.

Returns only in original packaging

Please use the manufacturer's original package to ensure a safe return.

Temperature check-up

Maintenance of temperature accuracy at regular intervals is recommended. The thermometer for use
should be equipped with wired sensing devices (e.g. Pt1000) and should have an accuracy of
measurements of 1/10 class B (∆T = ±0.03 °C) in the range of 0 to 100 °C. While processing the
temperature control, the room temperature should be 25 °C at maximum.

Calibration

If there is a reasonable suspicion that the device has deviated from the calibration range, because the
variations of the temperature check-up are out of the acceptable tolerance, a new calibration must be
carried out by the manufacturer. Please contact your VWR representatives.
