These sample vials are made of PFA and have a conical interior and raised graduation (5 ml subdivisions).

• Easy to clean
• Inertness against most chemicals
• Available with flat or cored outside bottom
• High thermal stability from –200 to +260 °C

PFA is especially suitable for use in trace analysis and has practically no carryover due to the hydrophobic, anti-adhesive, and smooth surfaces. The flat-bottom vials improve heat transfer and are recommended for hot plate use.
