Product Description

RELIGLAS four neck round bottom flasks are laboratory solutions for demanding synthetic, distillation, and multi-reactant processes. Choose between Angle (02.357) and Parallel (02.358) side neck geometries for optimal apparatus access and workflow compatibility. Each vessel is made from chemically resistant, thermally robust borosilicate glass and accommodates standard ground glass socket joints for leak-tight assembly.

These four-neck flasks facilitate cocurrent additions, gas inlets, temperature probes, and sampling—with robust stability from 100 mL up to 20 liters for analytical and kilo-lab to pilot plant processes. All necks are expertly fused for safety, compatibility, and lifetime reuse.
