Description
Woulff bottle 500 ml GL 18/GL 25 is a compact multi-neck laboratory bottle for filtration, vacuum and gas-handling work. It has a nominal volume of 0,5 l and is fitted with a bottom tubulature GL 25, two side necks GL 18 and a main neck GL 25, each supplied with screw caps for secure tubing or stopper connections. Measuring 155 × 85 mm and weighing 0,4 kg net, the bottle occupies little bench space while remaining easy to handle in crowded setups. The bottom outlet supports drainage or continuous liquid transfer, and the upper necks allow simultaneous connection of vacuum lines, wash bottles or reagent feeds. This arrangement matches the classic Woulff design used in filtration trains, solvent work-up and multi-port vacuum manifolds. The bottle comes from manufacturer Witeg and is compatible with standard GL thread accessories found in European laboratories. Supplied as a single piece, it is well suited to chemists and technicians who need a durable smaller multi-port glass vessel for controlled liquid and gas transfer under reduced pressure in research, analytical and preparative applications.
