1206 12. Environmental-, soil-, water-, food analysis Trace analysis/Tubes GENERAL CATALOGUE EDITION 20 E & OE. Round-bottom flasks, PFA Transparent, neck with NS 29/32. Can be used as a safety flask with a rotary evaporator. High thermal stability and chemical resistance. The advantages of PFA: - Especially suitable for use in trace analysis - 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, autoclavable. - Chemical inertness against nearly all chemicals - Good transparency and dimensional stability - Easy to clean - Use of high purity raw materials 1 VITLAB Capacity Diam.

The neck of each flask is slightly rounded for pouring and can be plugged with a stopper. The conical shape and neck design allow contents to be mixed or stirred with reduced risk of splashing. The narrow neck also helps limit evaporation and contamination. PFA material has the lowest metal ion content of any fluoropolymer. Ideal for use in titration and for the preparation of microbial cultures. - Chemically inert for ultra-pure applications - Graduated - Transparent for easy viewing - Non-stick PFA surface-easy to clean - Can be used in a microwave 2 Saint Gobain Capacity Height Neck diam.
