These heavy duty 250 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: Square bottles 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 wide range of optional caps are available for these bottles:nPolypropylene 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.
