High Chemical Compatibility and DurabilityEngineered from premium borosilicate glass and PTFE, these stopcocks withstand exposure to strong acids, bases, and organic solvents. Their robust construction ensures longevity even under harsh vacuum conditions. The PTFE plug provides excellent chemical resistance, maintaining the integrity of your laboratory setup during various experimental processes.
Versatile and Easy IntegrationDesigned to connect seamlessly using standard ground glass joints (14/23, 19/26), our stopcocks fit effortlessly into most laboratory glassware systems. Their clear bodies with distinct handle coloration allow quick visual identification and operation, enhancing workflow efficiency in research, quality control, and routine laboratory tasks.
Precise Manual ControlThe manual operation offers reliable, nuanced gas flow and isolation within vacuum manifolds. With either 2 or 3 ports depending on the manifold design, users can adjust or completely stop the passage of gases and liquids, offering flexibility and adaptability in filtering, reaction setups, and manifold maintenance.
FAQs of Other Vacuum Manifold Components - Stopcocks:
Q: How does a vacuum stopcock function within a laboratory manifold system?
A: A vacuum stopcock controls the flow and isolation of gases or liquids in vacuum manifolds and laboratory glassware. By manually turning the PTFE plug, users can open, restrict, or close specific pathways to regulate pressure, flow rates, or isolate sections as needed during experiments.
Q: What substances are vacuum manifold stopcocks compatible with?
A: These stopcocks are made from chemical-resistant borosilicate glass and PTFE, making them suitable for use with strong acids, bases, organic solvents, and laboratory gases commonly encountered in vacuum applications.
Q: When should I choose a custom bore size for my stopcock?
A: A custom bore size is beneficial when your application requires precise flow control or is outside the typical 2 mm or 4 mm bore range. Customization ensures optimal fit and performance in specialized laboratory processes or unique manifold setups.
Q: Where are these stopcocks typically used within laboratory environments?
A: They are commonly integrated as accessories in vacuum manifolds, filtration assemblies, and other glassware systems where precise control of vacuum or fluid pathways is necessary.
Q: What is the installation process for these stopcocks?
A: Installation involves inserting the stopcock into standard ground glass joints (such as 14/23 or 19/26) on your glassware or manifold. The tight PTFE and glass interface ensures a leak-free seal suitable for vacuum operations.
Q: What are the primary benefits of using a PTFE and borosilicate glass stopcock?
A: Combined, PTFE and borosilicate glass offer superior chemical resistance, a durable polished finish, excellent sealing, and long product life. This minimizes risk of leaks and chemical interference during working procedures.
