Description
Drain cock for tubulature bottles with PTFE spindle is a precision outlet fitting designed for controlled dispensing of liquids and reagents from laboratory bottles. It is intended for GL 32 threads and is compatible with 1 L to 2 L bottles, attaching via clamp screw connection to the base side arms of DURAN® suction or tubulature bottles. The PTFE spindle ensures smooth, chemically resistant operation for reliable flow control. Constructed from borosilicate glass 3.3, the cock offers the thermal and chemical durability expected in analytical and preparative work. This component from manufacturer Duran/DWK Life Sciences supports versatile use wherever GL 32 compatibility is required. It enables accurate dosing without the need for additional adapters, making it suitable for filtration setups, reagent transfer and general liquid handling on suction bottles. The combination of glass body and PTFE spindle provides a robust, low-maintenance solution for laboratories that rely on DURAN® bottle systems for safe and controlled drainage of aqueous or organic media.
