The VacuuCenter BVC basic is designed for connection to an existing external vacuum source like a diaphragm pump or a vacuum network (e.g., VACUU·LAN®) and does not require electric power. The chemically resistant mechanical vacuum controller always ensures an optimal operating vacuum. The controller opens only when needed thus limiting the gas load on the vacuum source. The evaporation of collected liquid is minimised. The inlet tubing integrated in the bottle head reduces aerosol and foam formation and ensures a long service life of the hydrophobic protection filter. The aspiration system is available either as BVC basic with 4 litre PP bottle or as BVC basic G with 2 litre coated borosilicate glass bottle.

Supplier: VACUUBRAND

The VacuuCenter BVC control serves for efficient and convenient aspiration of supernatants. The vacuum level - and thus the suction force - is precisely adjustable via the electronic touch panel and allows a sensitive and reproducible operation. The chemically resistant diaphragm vacuum pump is automatically turned on and off as needed, which reduces the low noise level even further. The BVC control is available in two complete equipment options with different collection flasks. The 2 litre borosilicate glass bottle with a protective coating has a very high chemical resistance. For larger amounts of liquids the 4 litre bottle of unbreakable polypropylene (PP) is used. The smooth surfaces allow an easy cleaning of the systems.

The DCP 3000 is an outstanding vacuum gauge with large illuminated display. The brand new VSP 3000 vacuum sensor is based on thermal conductivity (Pirani) and offers a wide measurement range from atmospheric pressure down to 10 to 3 mbar. The wetted parts are made of chemically resistant plastics (PBT, PUR) and alumina ceramics. It features a much better chemical resistance and ruggedness than conventional Pirani sensors with their fragile metallic spiral-wound filament. Simultaneous connection of up to eight vacuum sensors allows flexible measuring on the spot. The DCP 3000 communicates with external components via the VACUU·BUS® digital bus system. It is characterised by fully automatic configuration, unified plug connections and cable lengths of up to 30 m. In addition the DCP 3000 offers relative pressure measurements (VSK 3000 as reference) and a data logger feature for up to 32000 data values.
