Ultra-pure PFA Volumetric Flask Class A 250ml can be used for semiconductor experiments

PFA Volumetric flasks are translucent, and meet Class A tolerances per DIN EN ISO 1042. Flasks are molded PFA, which is highly resistant to heat and chemical contamination. PFA surface properties offer superior clean-up compared to glass and reduces risk of sample carryover in trace analysis applications. Screw cap design provides reduced contamination risk, compared to traditional stopper design. Advantages: 1.High Temperature Resistance ：-200 to +260℃ 2.Ultra low dissolution and precipitation 3.Low blank value of metal elements 4.Strong acid and alkali resistance 5.Chemical stability Tel：+86 13913985644 WhatsApp：13913985644 Gmail：adanjbzh@gmail.com Store website：https://www.njbinglab.com
