PYREX borosilicate glass provides exceptional chemical and thermal resistance
When used with a PBT high-temperature cap and ETFE pouring ring (16157-497, see 16157-071 series), bottles can withstand repeated sterilization cycles up to 180°C (356°F) dry heat.
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.
Square design saves 13–20% of shelf space, and slightly convex walls minimize glass-to-glass contact during autoclaving. Rounded edges allow easy cleaning. Bottles feature white graduations and a large marking spot. A glass ridge molded into the bottle indicates full capacity. Autoclavable.
Ordering information: Each bottle is supplied with a linerless, autoclavable, one-piece, orange polypropylene screw cap with a drip-free pouring ring. See 16157-071 series of media bottles for replacement caps, pouring rings, open top caps, and septa.
