Vertical Laminar Flow Benches Telstar® V-30/70

Vertical laminar flow benches deliver an ultra clean laminar airflow over a working bench to protect manipulated products from dust, from environment contamination and from cross-contamination in the working area. They are an ideal solution for the handling of non-hazardous biological samples (cell and tissue culture) as well as for optics and electronics.

Telstar® offers 2 series of vertical laminar flow benches: V-100 series and the V-30/70 series with air recirculation.

70 % of the air is recirculated thus minimising filter clogging and the other 30 % are expelled through a HEPA H 14 at top of the unit. All models are supplied with working area CLASS 10 as defined by U.S. Fed . Std. 209 a S.S . 5295.
  • Cabinet frame is made of stove-enamel coated steel.
  • Minimised width and height are compatible with all laboratory doors and dimensions.
  • Easy access to main filter from the chamber, for replacement.
  • Removable tempered glass chamber sides.
  • Pivoting front window with gas springs to maintain it in open position for the introduction of large items and for easy cleaning of chamber and of window.
  • St. steel divided working tray.
  • Electric socket 230 V at the rear of the chamber.
  • Equipped with an intuitive electronic control system which offers fast and complete control over all cabinet functions.
