Sample tubes made from PFA for sample preparation, centrifugation and for use in
autosampler racks. With or without individually calibrated ring mark at 10 ml with
GL 25 screw cap made from PFA or PE stopper (see Table).

The advantages of PFA
• Especially suitable for use in trace analysis
• No memory effects
• Practically no carryover due to the extremely hydrophobic, anti-adhesive,
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
