Sterile polyethylene terephthalate glycol (PETG) Erlenmeyer flasks are ideal for containing, mixing, and storing solutions and are a safe and shatterproof alternative to glass. These crystal-clear flasks feature molded-in graduations allowing you quick volume assessment. Liquid sticking-resistant design at the neck repels liquid for easier pouring. They have a temperature range of -60 to 60 °C (-76 to 140 °F) and are not autoclavable.
HDPE caps are included. Choose from a leakproof plug seal cap or a vented cap with 0.22 µm hydrophobic PTFE membrane for continuous gas exchange.

Manufactured in an ISO Class 8 (formerly Class 100,000) cleanroom environment, these individually packaged Erlenmeyer flasks are sterilized by gamma irradiation per ISO 11137-2 (SAL 10-6), and are ISO 13485 and ISO 9001 certified, DNase/RNase free, and nonpyrogenic.
