HLF for Operator Protection (HLFOP 2000)

HLF Workstation is designed to provide excellent view of the working area, are manufactured from materials that are resistant to corrosion and easy to clean. This hood provides horizontal laminar airflow and has 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. Lighting from a fluorescent white light aids the internal brightness and comfort for the operator.

HLF Laminar Flow Workstation is manufactured to comply with the guidelines of ISO 14644 – 1:1999 Class 5 (Fed. Standard 209E:1992 Class 100), to provide sterile working environment and air velocity at filter face of 89fpm-1. Lighting from an 18W fluorescent white light aids the internal brightness and comfort for the operator. Laminar Flow Cabinets are manufactured to a very high standard using only the best quality materials, fans and components.  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.

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 air through 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.

When it is required to protect the operator from particulate and also chemical fumes or solvents vapours which are released during your handlings and procedures, then a Bigneat HLFO cabinet/workstation is ideal. Essentially of the same design as a HLF cabinet/workstation with flow reversed and filtration system reconfigured with a more powerful fan and different filter arrangement. It returns particle-free, clean-air, back into the laboratory and provides an even flow across the work area. This cabinet style allows excellent view into the work area to the front and through the side panels.
