Glass or PTFE Laboratory Stopcock
The laboratory stopcock is an essential component for precise control of liquid or gas flow in laboratory systems. Available in borosilicate glass 3.3 or PTFE (polytetrafluoroethylene), it provides a balance of accuracy, durability, and chemical resistance for demanding applications.
Main Features
- Precise flow control: Bore of 2.5 mm or 4 mm for uniform regulation.
- Universal compatibility: Connection tubes from 8 to 13 mm for integration with standard laboratory setups.
- Available materials:
- Borosilicate glass 3.3: Excellent thermal and chemical resistance, ideal for corrosive environments.
- PTFE: Chemically inert, self-lubricating, and resistant to solvents and acids.
- Manufacturing standard: DIN 12 540-1 ensures quality and compatibility with European laboratory systems.
- Design: Precision ground conical bore for tight sealing and minimal pressure loss.
- Applications: Analytical chemistry, gas control, vacuum systems, distillation, and reactors.
Advantages of Borosilicate Glass
Borosilicate glass features low thermal expansion and high thermal shock resistance, maintaining structural integrity even under rapid temperature changes. This ensures long service life and reliability in demanding environments.
Advantages of PTFE
PTFE delivers exceptional performance in chemically aggressive environments. Its inert nature and low friction provide smooth, maintenance-free operation and reliable sealing.
Available in different bores, diameters, and materials, our laboratory stopcocks guarantee safe and precise flow control for every scientific setup.
