Pear shape flasks, DURAN®, standard ground joint 14/23, 25 ml, 1 unit(s)

Pear shape flasks DURAN® with standard ground joint 14/23 and a 25 ml capacity are compact laboratory vessels designed for small-scale reaction, distillation and concentration work. The pear-shaped body concentrates residual volumes toward the base, supporting efficient recovery of limited sample amounts and clear observation of the liquid phase during heating or cooling. A precision standard ground joint 14/23 enables secure connection to condensers, adapters, stoppers and other jointed glassware in modular assemblies. Manufactured from DURAN® glass by Lenz, the flask suits routine organic synthesis, sample preparation and teaching laboratories where reliable joint geometry and chemical resistance are required. Supplied as a single unit with a net weight of 0,030 kg, it integrates easily into existing ground-joint setups without additional adapters for NS 14/23 interfaces. The pear profile is particularly practical when working with viscous residues or when complete drainage of the vessel is important. Ideal for preparative workflows, solvent exchange steps and small-volume evaporations that demand a stable, jointed glass flask of defined capacity.
