DuPont™ Tyvek^® 500 Xpert, model CHF5. Hooded coverall available in white, in sizes S to XXXL. Robust yet lightweight (<180g per garment). 3-piece hood for optimal fit to head and face when turning. Elasticated face, wrists and ankles as well as glued-in waist elastic. Wide crotch area for freedom of movement. Large, easy-to-grasp zipper puller.
Tyvek^® garments are composed of flash spun, high density polyethylene, providing an ideal balance of protection, durability and comfort. Tyvek^® is permeable to both air and water vapour, yet repels water-based liquids and aerosols. It offers an excellent barrier against fine particles and fibres (down to 1 micron in size), is ultra-low-linting and antistatically treated. Silicon non-added.
Applications for Tyvek^® Classic Xpert garments include those found in pharmaceutical handling, chemical processing, the oil and gas industry, general maintenance and operations and many others.

• Chemical protective clothing, Category III, Type 5-B and 6-B
• EN 14126 (barrier to infective agents), EN 1073-2 (protection against radioactive contamination)
• Antistatic treatment (EN 1149-5) - on both sides
• Stitched external seams featuring patent-pending technology for enhanced liquid spray tightness
• Very low inward leakage thanks to optimised design
• Tyvek^® auto-lock zipper and zipper flap for increased protection

Using the Dräger activated charcoal tubes or silica gel tubes, hazardous substances in the air are collected using a suitable medium via adsorption or chemisorption. The sample is then analysed in the laboratory by means of various analytical methods such as gas chromatography (GC), high performance liquid chromatography (HPLC), UV-VIS photometry, or IR spectroscopy.

This air displacement micropipette allows subsequent pipetting of 1 and 0.1mL of same liquid. The two pre-calibrated fixed volumes eliminate any setting. A universal metal nozzle accommodates straw tips (length 190mm, diameter 4 mm), most adequate to aspirate from deep, narrow vials or Stomacher bags.
Ideal alternative to conventional graduated glass pipettes when performing serial 1:10 dilutions in bacteriology.
