Features:
- Made from non-breakable PFA (perfluoroalkoxy) copolymer, which offers reduced risk of sample carryover in trace analysis applications
- Easy to clean - PFA surface properties offer superior cleanability to glass, PTFE and PP containers. Cleaning recommended below 60°C to preserve graduation marks
- PFA containers often extend the stability of low (ppb) concentration standards, which reduces time and cost of renewing trace analysis standard solutions
- Very low absorption and permeability levels associated with PFA
- Include PFA screw caps with molded sealing rings
- Translucent - highly transparent surfaces simplify meniscus verification
- Visible, accurate and permanent graduations for precise measuring
- Calibrated to contain (TC) - when filled to the circumference marking on the neck, flask will contain exact designated amount of liquid in ml
- Good chemical and solvent resistance over a temperature range of -260° to +270°C
- Inert with most reagents, including nitric and hydrochloric acid routinely used in cleaning trace analysis labware
- Can be sterilized using gas, dry heat, gamma irradiation, or chemical disinfectant
- Autoclavable at 250°F (121°C) without affecting tolerances
- Includes batch certificate
- Meet Class A tolerances per DIN EN ISO 1042
- Meet ASTM E 288, E 542 and E 694 standards

Plastic:
The PFA volumetric flasks with screw closures feature high translucency and individually calibrated ring markings. These plastic volumetric flasks are calibrated to contain (TC) volumes ranging from 25 ml to 500 ml. The PFA screw closures with molded sealing rings provide hermetic seals and safety from outside contamination. Withstands high temperatures (270°C) and has outstanding chemical resistance. Leakproof. Produces excellent results in ICP-MS, production and storage of trace analysis standards, isotope separations, sample digestions and more. These volumetric flasks are autoclavable at 250°F and can be sterilized via dry heat, gas, gamma irradiation or chemical disinfectant.
*Factory Ship Item, allow 3 to 5 days for shipment.
