SIMAX borosilicate 3.3 blank flasks are precision-formed semi-finished glass vessels designed specifically for scientific glassblowers and lampworkers to shape, finish, and fabricate into completed laboratory apparatus. Available in round bottom, Erlenmeyer, flat bottom, Kjeldahl, filter, and Fernbach formats, SIMAX blanks feature consistent wall thickness, smooth pore-free surfaces, and the reliable workability that borosilicate 3.3 glass is known for. 

SIMAX borosilicate 3.3 blank funnels are semi-finished glass forms supplied to scientific glassblowers for custom fabrication and finishing. Available in separatory and standard funnel profiles, SIMAX blanks deliver the optical clarity, thermal shock resistance, and chemical durability required for demanding laboratory applications. 

Borosilicate 3.3 bell jars are heavy-walled, optically clear enclosures manufactured for vacuum operations, sample protection, and controlled laboratory environments. The precision ground flange base provides a reliable sealing surface against suitable baseplates and gaskets, making SIMAX bell jars suitable for vacuum desiccation, atmospheric isolation, and experimental enclosures.

Borosilicate 3.3 glass joints are the essential connectors for building, repairing, and customizing laboratory glass assemblies. The range includes ground conical joints, spherical joints, flat flanges, long-tip joints, bushings, and joint clips - all manufactured to DIN and ISO standards for consistent sizing and leak-free performance.

SIMAX borosilicate 3.3 glass screwthreads are precision-formed glass components used by glassblowers to construct and repair apparatus with screwthread connections. The range covers GL, SVL, Quickfit, and Torion thread systems, alongside matching screw caps, sealing rings, washers, couplings, and stirrer bearings — providing a complete selection of screwthread hardware for any assembly.
