• PFA for extreme chemical resistance
• Screw caps help maintain sample integrity

Highly translucent, hydrophobic surfaces ensure easy meniscus verification. Made of PFA (perfluoroalkoxy copolymer). Highly heat- and chemical-resistant, autoclavable, and easy-to-clean. Can withstand temperatures from –200 to 260 °C (–328 to 500 °F). PFA screw caps help protect against outside contamination.
