Pyrex® Square Media Bottles

Heavy duty Corning Pyrex® graduated, square media bottle is manufactured from Pyrex® borosilicate glass code 7789 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, a large marking spot and a glass ridge molded into the bottle to indicate full capacity. Bottle includes a linerless, one-piece autoclavable orange 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 this bottle.
