Cellulose MN 301: native fibrous cellulose, standard grade, fiber length (95 %) 2–20 μm, average degree of polymerization 400–500, specific surface acc. to Blaine 15000 cm2/g ≤ 20 ppm Fe, 6 ppm Cu, 7 ppm P, CH2Cl2 extract ≤ 0,25 %, residue on ignition at 850 °C ≤ 1500 ppm

Mininert valves are very convenient for repetitive sampling and limit content exposure to the silicon septum. Models are available for screw-cap and crimp-top vials. The crimp-top valve for 20 mm ID glassware slides into the neck of the vial. Turn the threaded flange to secure a tight fit.

Unlike brass brushes that can leave a metal residue, these stainless steel tube brushes (3/8-, 3/16-, and 1/4-inch) work well for cleaning dirty collectors, injector ports, and detector ports. The surface brush can be used to remove residue that builds up on metal detector jets and electronic contacts.

Excellent thermal stability at injection port temperatures up to 450°C!

Click-On Traps measure: 8 1/2" x 1 1/4" (21.6 x 3.2cm) Note: Replacement trap only—fittings sold separately.
