Description
Conical dropping funnel, 250 ml, NS 29/32 with PTFE plug is laboratory glassware designed for controlled liquid addition in preparative chemistry and related analytical work. The conical vessel shape supports easy level reading and complete drainage, while the NS 29/32 ground joint locks securely onto compatible flasks and apparatus. A PTFE plug delivers chemically resistant, adjustable flow for dropwise or continuous introduction of solvents, reactants and solutions. Packed as 1 pc(s) and weighing 0,485 kg, the funnel is well suited to medium-scale organic synthesis, extraction sequences and general laboratory metering. From manufacturer Lenz, the unit follows widely used European joint standards, allowing straightforward coupling with existing glassware trains. Conical geometry combined with a PTFE plug promotes reliable shut-off and reproducible delivery throughout multi-step procedures. Research groups, teaching laboratories and quality-control facilities can deploy this dropping funnel wherever 250 ml capacity, standard joint fit and dependable flow regulation are needed for routine experimental work.
