9 Maintenance and repair
9.1 Cleaning and Maintenance
The TProfessional Basic was built to operate for a long time without the need for periodical
maintenance. Nevertheless, occasionally cleaning of the air inlet may be necessary to maintain
the efficiency of the Thermocycler. Insufficient airflow may lead to reduced heating and cooling
rates (see chapter 8.1). The inlet for the airflow is located at the bottom side of the instrument.
Be sure that the inlet is not clogged by dust or other material (e.g. a sheet of paper placed
under the cycler can be attached to the inlet as the fan is in operation). Dust can be removed
easily from the inlet with a conventional vacuum cleaner. Additionally, the Thermocycler housing
may be cleaned from time to time with a smooth cotton cloth. Do not use strong detergents or
organic solvents for cleaning. Never treat silver block with abrasive agents.
Important: Appropriate safety regulations must be observed when working with infectious or
pathogenic material.
9.2 Servicing and repair
The TProfessional Basic Thermocycler contains no user serviceable parts. Do not open the
housing instrument. Service and repair may only be carried out by the Biometra Service
