These heavy duty Pyrex® round bottles are manufactured from low actinic glass for use when storing or transporting light sensitive materials. 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.
A wide range of optional caps is 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 0.22µm 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
Caution: DO NOT tighten caps immediately after autoclaving as the vacuum resulting from cooling can cause breakage.
