PYREX® 150 mL Round Media Storage Bottles, with GL45 Screw Cap

These heavy duty 150 mL PYREX® round bottles can be used for storage as well as mixing and sampling. They include a linerless, one-piece autoclavable orange polypropylene plug seal GL45 threaded cap with a drip-free pouring ring. New glass bead indicates full capacity line. Bottles have permanent white enamel graduations and marking spots.

Caution:DO NOT tighten caps immediately after autoclaving as the vacuum resulting from cooling can cause breakage.

• Polypropylene colored caps in a choice of orange, green, purple, red, and light gray for ease of sorting and identification.
• Vented membrane cap with 0.22 µm PTFE hydrophobic membrane.
