Round-bottom flasks, PFA

Description
Transparent, neck with NS 29/32. Suitable as safety flask for use with rotary evaporators to collect the distilled off liquid. 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
