Work with PCR and other molecular biology techniques often requires a contamination-free workplace. The UV source, controlled by a timer (0-24 hrs), denatures unwanted DNA on reagents as well as pipetting and laboratory aids in 5 to 30 minutes. The up to 8 mm thick acrylic / glass walls also provide safe protection against UV and isotope radiation such as 32P. By using the UV/Air-Cleaner, freedom from contamination can also be guaranteed during the work process. Here, the air is continuously circulated with a circulation volume of 14 m3 / hr directly past a covered UV lamp (254 nm). During breaks, the direct-radiation UV lamp can also be used to decontaminate the work surface and tools. The UV cabinet has an easy-to-clean stainless steel work surface and is available in two different versions.
