PYREX borosilicate glass provides exceptional chemical and thermal resistance. 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. Bottles can withstand freezing to –40°C (–40°F). 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. Ordering Information: Each bottle is supplied with a linerless, autoclavable, one-piece, orange polypropylene screw cap with a drip-free pouring ring. See the 16157-071 series of media bottles for replacement caps, pouring rings, open top caps, and septa. | Capacity, mL (oz.) | GPI Thread Finish | Graduation Range, mL | Graduation Interval, mL | Corning* No. | | Square Bottles | | 100 (3.4) | GL32 | 40–80 | 20 | 1396-100 | | 250 (8.5) | GL45 | 50–200 | 50 | 1396-250 | | 500 (17) | GL45 | 100–400 | 100 | 1396-500 | | 1000 (33.8) | GL45 | 100–900 | 100 | 1396-1L | | Open Red PBT High Temperature Caps | | — | GL25 | — | — | 1395-25HTSC | | — | GL32 | — | — | 1395-32HTSC | | — | GL45 | — | — | 1395-45HTSC | | Silicone Septa | | — | GL25 | — | — | 1395-25SS | | — | GL32 | — | — | 1395-32SS | | — | GL45 | — | — | 1395-45SS | | PTFE-Faced Silicone Septa | | — | GL25 | — | — | 1395-25TS | | — | GL32 | — | — | 1395-32TS | | — | GL45 | — | — | 1395-45TS |
