Corning Pyrex 5l Round Media Storage Bottles, With Gl45 Screw Cap

These heavy duty 5L 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. Bottles have permanent white enamel graduations and marking spots.

Caution: Bottles larger than 2L should NOT be used with bottle top 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 vented cap is NOT recommended for use on the 5L bottle for venting during autoclaving.

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

• 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.
• Red 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.
