1209 12. Environmental-, soil-, water-, food analysis Trace analysis/Tubes GENERAL CATALOGUE EDITION 20 E & OE. Measuring cylinders, graduated, PFA These graduated cylinders offer all the advantages of non-stick inert fluoropolymers. PFA is temperature resistant from -196 °C to 260 °C and has the lowest metal ion content. As a result, Chemware ® cylinders are excellent for trace metal analysis. - Easy-to-read graduations - Smooth pouring, drip-free spout - Broad base for stability 1 Saint Gobain Capacity Height PK Cat.

Ring mark individually calibrated to `Iná. Class A tolerances according to DIN EN ISO 1042. The PFA screw cap guards against contamination. Outstanding chemical resistance, can be used with strong oxidants, highly concentrated acids and alkalis, hydrocarbons, and ketones. With laser-engraved lot number and batch certificate. Thermal stress up to 121 ºC (autoclaving) does not permanently exceed the tolerance limit. To preserve the ring mark, do not clean at temperatures exceeding 60 ºC. The advantages of PFA - Long-term maintenance of low-concentration reference materials in PFA containers - No memory effects - Practically no carryover, no cross-contamination due to the extremely hydrophobic, anti-adhesive and smooth surfaces - High thermal stability, from -200 °C to +260 °C - Chemical inertness against nearly all chemicals - Good transparency and dimensional stability, suitable for volumetric instruments - Easy to clean - Use of high purity raw materials 2 VITLAB Capacity Tolerance Height Neck thread PK Cat.

Approx. pore size 50 µm for optimal formation of gas bubbles into the liquid. Because all parts are made of high-quality fluorocarbon resins, a broad range of applications are possible. The threaded inlet and outlet connections accept 4 x 6mm i.d. x o.d. tubing , (1000 ml version: 5 x 8mm i.d. x o.d. tubing). 3 VITLAB Capacity Diam. Height PK Cat.
