These heavy duty Pyrex®PLUS® round bottles have a protective PVC coating to help prevent glass from shattering and reduces spills. Bottles are autoclavable at 121°C and resistant to thermal shock. Bottles have GL-45 threaded necks and come with autoclavable, one-piece, teal colored polypropylene plug seal caps with drip-free pouring rings. Glass bead indicates full capacity line. Teal enameled graduations and marking spot. PLEASE NOTE: DO NOT PLACE THESE BOTTLES OVER DIRECT HEAT OR FLAME. DO NOT HEAT ABOVE 121°C MOIST HEAT OR 110°C DRY HEAT.
CAUTION: DO NOT have caps tightened immediately after autoclaving as the vacuum resulting from cooling can cause breakage. 2L bottles should NOT be used with bottle top filter units, or in other applications involving vacuum pressure, as breakage may occur.
