These leach-resistant bottles are excellent for long term storage of solvents and trace analysis standards. They are manufactured from PFA (a perfluoxy copolymer) for excellent resistance to heat and chemical contamination. PFA surface properties offer superior cleanability to glass, PTFE and polypropylene containers, reducing risk of sample carryover in trace analysis applications. These bottles can be autoclaved using heat, gas, and chemical methods for sensitive biological applications.
