Products Glass Flask solutions from Zhejiang Liquan Biotechnology Co., Ltd. support mixing, heating, measuring, and storage in professional laboratories. We are a China-based manufacturer operating under ISO13485, with site references to ISO9001 and CE. Standard borosilicate 3.3 construction delivers durability, chemical resistance, and stable thermal performance. Common capacities range from 50 mL to 5 L, with narrow or wide necks, ground glass joints, and closure options including glass, PE, or PTFE stoppers.
Borosilicate glass offers low thermal expansion, good thermal shock resistance, and clear, readable markings. Controlled production in a 100,000-level cleanroom supports cleanliness and consistent batches. Our quality systems and documented inspections help ensure dependable performance in IVD, bioresearch, medical, and pharmaceutical workflows.
Volumetric flasks enable precise standard preparation with Class A or B accuracy. Erlenmeyer (conical) flasks suit mixing, titration, and media preparation. Round-bottom (boiling) flasks provide even heating for reflux and synthesis. Distilling flasks integrate sidearms and joints for simple or fractional distillation. Filtering/vacuum flasks feature thick walls and sidearms for vacuum filtration. Kjeldahl flasks support digestion procedures for nitrogen analysis.
| Task | Recommended Type |
|---|---|
| Prepare standards to volume | Volumetric flask (Class A/B) |
| General mixing and titration | Erlenmeyer flask |
| Reflux, synthesis, distillation | Round-bottom or distilling flask |
| Vacuum filtration | Filtering/vacuum flask |
Narrow necks reduce evaporation; wide necks ease additions and cleaning. Verify ground glass joint compatibility across condensers and adapters. Choose glass, PE, or PTFE stoppers based on chemical exposure and temperature. Screw-threaded designs are available where rapid access is needed.
Pair your flasks with condensers, adapters, Büchner funnels, tubing, clamps, and stands to build safe assemblies. Magnetic stirrers support homogeneous mixing during preparation and reaction setups.
Request quotes for standard sizes or customization of capacity, markings, joints, necks, stoppers, and color printing. High-capacity production and R&D-driven improvements support stable supply for research, medical, and pharmaceutical applications.
