Seamlessly bridging different joint sizes and connecting flexible tubing to rigid glass systems is essential for modular laboratory setups. LabFriend offers a versatile range of tubing adapters, located within the distillation and synthesis section of our distillation, separation, and filtration department. These professional-grade components are precision-engineered to maintain system integrity during synthesis, distillation, and gas handling.
Why Choose Professional Tubing Adapters?
Our curated collection of glass and plastic adapters is designed for chemical compatibility and secure mechanical fitment:
- Precision Expansion & Reduction: We stock Lenz-Laborglas Reduction and Expansion Adapters, allowing you to transition between different NS joint sizes (e.g., NS 14/23 to NS 29/32) while ensuring a vacuum-tight seal.
- Secure Threaded Connections: Utilize Lenz-Laborglas Screw Cap Tubes (GL 14 and GL 18) with integrated NS 14/23 cones, enabling the direct connection of probes or tubing to standard ground glass ports.
- Durable Screw Caps: Explore DWK Duran Screw Caps with Aperture (GL 18 to GL 45), featuring various bore diameters to secure tubing or sensors via septum or washers.
- High-Grade Borosilicate: Lenz-Laborglas glass adapters are manufactured from premium borosilicate glass for maximum thermal and chemical resistance.
LabFriend supplies tubing adapters from the leading brands in laboratory glassware and closures:
- Lenz-Laborglas: German specialists in high-precision ground glass, offering a comprehensive array of NS joint adapters and GL-threaded tubes.
- DWK Life Sciences: Features the premium Duran range of PBT screw caps with apertures, essential for building customized, leak-proof glass-to-tubing interfaces.
- Bohlender: Specialists in high-performance fluoroplastic labware, offering durable components for demanding chemical environments.
- ISOLAB: Provides a range of reliable glass adapters for standard laboratory distillation and synthesis assemblies.
Adapters provide the necessary modularity for complex rigs; to further enhance your distillation or synthesis workflow, we recommend exploring these related categories:
- Reaction & Distillation Components: Use adapters in conjunction with ISOLAB bent delivery tubes and Lenz-Laborglas distillation cones.
- Reflux Condensers: Connect your LLG Allihn or Dimroth condensers to flasks with mismatched joint sizes using reduction adapters.
- Stopcocks & Valves: Integrate Lenz-Laborglas straight-bore stopcocks into your tubing lines for precise flow control.
- NS Joint Accessories: Ensure your adapters remain securely fastened with ISOLAB POM clips or Lenz safety clips.
Unsure if you need a GL 14 or GL 18 adapter for your specific sensor diameter? Our team provides local technical support to help you find the perfect connection solution with fast shipping and competitive pricing.
Frequently Asked Questions
1. What is the difference between a reduction and an expansion adapter?
A reduction adapter allows you to fit a smaller male joint into a larger female joint, while an expansion adapter allows a larger male joint to fit into a smaller female joint on your apparatus.
2. Why use screw cap tubes with NS joints?
Lenz-Laborglas screw cap tubes allow you to convert a ground glass port into a threaded GL port. This is useful for inserting thermometers or gas inlet tubes through a screw cap for a secure, adjustable fit.
3. What are "Screw Caps with Aperture" used for?
These caps, such as the DWK Duran GL 25 or GL 45 models, have a hole in the top. They are used to secure tubing or electrodes into a flask using a silicone ring or septum.
4. Are these adapters suitable for vacuum applications?
Yes, precision-ground Lenz-Laborglas adapters are designed to be vacuum-tight when used with a small amount of joint grease or high-quality joint clips.
