PYREX® 500 mL Square Glass Media Storage Bottles, with GL45 Screw Cap

These heavy duty 500 mL square bottles are manufactured from PYREX® borosilicate glass for chemical and thermal resistance. Square bottles are easier to handle, require less space (13-20%) on the shelf or in the autoclave and are ideal for mixing, sampling and storage. Features include white enamel graduations, large marking spot and a glass ridge molded into the bottle to indicate full capacity. Bottles include a linerless, one-piece autoclavable orange GL45 threaded polypropylene plug seal cap and a drip-free pouring ring.

Caution:方形瓶子和瓶盖不应使用filter units, or in other applications involving vacuum pressure, as breakage may occur. DO NOT tighten caps immediately after autoclaving as the vacuum resulting from cooling can cause breakage.

A wide range of optional caps are available for these bottles.

• Polypropylene colored caps for ease of sorting and identification.
• Vented membrane cap with 0.22 µm PTFE hydrophobic membrane.
• PBT (polybutylene terephthalate) solid caps and ETFE pouring rings for dry heat sterilization (180°C).
• PBT caps with silicone septa for syringe sampling or introduction of reagents.
