Biosafety cabinets (BSC) class I or II are indispensable for cell culture work and R&D in life science. They offer high protection level inside and outside for prices up to more than 10.000 €. This investment for safety without compromise is questioned when the most common added accessory, an aspiration pump, is inadequate and questions the whole safety concept.
Aspiration pumps with 2-4L waste collection bottles are too big to be placed inside the BSC. Being placed outside, potentially bioactive liquids are pumped out of the safe containment of the BSC. Therefore, the liquid aspiration systems BioChem-VacuuCenter BVC from Vacuubrand offer uncompromised comfort and safety:
To maximize safety furthermore and to cover even unlikely events of failing 0.2 micron filters, it may also be advisable to feed the exhaust of the aspiration pump back into the BSC – preferably direct prior to the internal HEPA filter. This exhaust air handling port should be offered by manufactures of biosafety cabinets and is supported by VACUUBRAND BioChem-VacuuCenter types BVC control and BVC professional.
