PYREX® Square Bottles with Screw Caps

Made of PYREX® borosilicate glass, with linerless, one-piece, orange PP screw cap with a drip-free pouring ring.

• Exceptional chemical and thermal resistance
• Rounded edges allow easy cleaning
• White graduations and a large marking spot
• Glass ridge moulded into the bottle indicates full capacity
• Autoclavable

Square design saves 13 to 20% of shelf space, and slightly convex walls minimize glass-to-glass contact during autoclaving.

Further PP colored screw caps for ease of sorting and identification, vented membrane screw caps with 0.22 µm PTFE hydrophobic membrane, PBT solid or open top screw caps and ETFE pouring rings are optionally available.

Caution: Do not tighten caps immediately after autoclaving as the vacuum resulting from cooling can cause breakage. Square bottles should not be used with bottle top filter units, or in other applications involving vacuum pressure as breakage may occur.
