Description

Heavy duty 50mL borosilicate Schott® glass media bottles can be used for storage as well as mixing and sampling. GL32 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: Only bottles smaller than 2L can be used with bottle top filter units, or in other applications involving vacuum pressure, as breakage may occur in 2 liter or larger bottles. DO NOT have caps tightened immediately after autoclaving as the vacuum resulting from cooling can cause breakage.
