VLF for Product Protection (VLF 1000)

Bigneat’s Laminar Flow Workstations have been specifically designed to be affordable yet to provide particle-free, bacteria-free, clean air conditions to the work area at a quality standard usually only possible in more expensive cabinets. Materials used are resistant to corrosion and easy to clean. Experience has shown that Bigneat Laminar Flow Cabinets give consistent performance which is only dependent on replacement of the pre- and HEPA filters at recommended intervals. VLF laminar flow workstation providing particle-free, sterile air conditions to the work surface. This workstation offers excellent clear view of the working area and is portable. Lighting from a fluorescent white light aids the internal brightness and comfort for the operator. Room air is drawn into the top of the cabinet, passes through the pre filter and enters the fan housing. The speed controllable fan pushes the airthrough the HEPA filter located above the working area. Ultra-clean air exits the HEPA filter to provide a sterile working environment which protects the samples and manipulations from external contamination. The cabinet structure is fabricated from 10mm thick clear UV stabilised cast acrylic which provides excellent all-round visibility for the operator whilst carrying out manipulations and aseptic procedures.

VLF Laminar Flow Hoods are built to a very high standard using only the best quality materials and fan components and are manufactured to comply with the guidelines of ISO 14644 – 1:2000 Class 5 (Fed. Standard 209E:1992 Class 100), to provide sterile working environment and air velocity at filter face of 0.45 m/s.
