In-line Venting and Filter, Thin Format

  • Thin line in-line venting and filtration units are ideally suited for venting applications and filtration of fluidic volumes too large for syringe filters.
  • Variety of standard filter media including borosilicate glass microfiber
  • Barbs are a 5-15mm tapered step with 4mm ID, compatible with slip port style high volume syringes
  • Ultrasonically welded (no adhesives or solvents) to withstand light duty vacuum (<70cmHg) or positive pressure (50psi)
  • Light weight filter will not kink most vent tubing, a problem that causes failed reactions and low yield incubations
  • Transparent inlet side allows a visual indication of filter loading
  • Typical applications include venting of carboys, stir bottles, reservoir tanks, bio reactors and low-pressure reactor flasks
  • Suited for vacuum or positive pressure filtration applications and tank to smaller vessel transfers and filtration of media or broth
  • Operates with very low backpressure, even wetting and linear flow rates
  • Polypropylene housing is molded with pure virgin material, naturally chemical resistant and has very low extractables commonly known to cause background noise for analysis applications
  • Made in the USA and QA tested using a 12-point pre and post manufactured methodology

  • Filtration area: 20.0cm2
  • Hose Barbs: 5-15mm stepped, ID 4mm (consistent with syringe slip port OD)
  • Excellent lot-to-lot reproducibility and are verified against a standard using analysis techniques such as GC, TGA & DSC.
  • Manufactured in the USA

Laboratory Spill Containment Bench Pad / Wipe

  • Designed with a complex proprietary fused 100% Polypropylene (PP) fibrous matrix which is a lightweight polyolefin
  • Has high chemical resistance to most short term exposure of organic solvents, acids and alkalis
  • 290g/m2 basis weight sufficient to easily handle typical lab bench volume spills up to 600ml safely and quickly.
  • Lays flat as a bench pad with sufficient stiffness reducing “bunch up” seen with other competing brands
  • Soft enough to be used as a wipe
  • Binding dots accumulate fluids and migrate deeper into the pad
