Heavy duty 20,000mL (20 liter) borosilicate Schott® glass media bottles can be used for storage as well as mixing and sampling. GL45 Closures are liner-less, one-piece autoclavable polypropylene. These high quality Schott® media bottles have permanent white enamel graduations and marking spots. Made in Germany.
Optional red PBT caps and red ETFE pouring rings are also available for dry heat sterilization to (180°C.) Additionally, other solid polypropylene caps are available in orange, green, purple, red, and light gray, or you can order open-top caps with PTFE/Silicone septa.
CAUTION: Bottles larger than 2L should NOT be used with bottle top filter units, or in other applications involving vacuum pressure, as breakage may occur. DO NOT have caps tightened immediately after autoclaving as the vacuum resulting from cooling can cause breakage. A vented cap is NOT recommended for use on the 5L, 10L or 20L bottle.
