Frequently Asked Questions
1. What is the purpose of a pressure compensation set?
The DWK Duran pressure compensation set allows air to enter the bottle as liquid is withdrawn, preventing a vacuum that could stall your HPLC pump, while keeping dust out.
2. Will GL 45 caps fit all laboratory bottles?
GL 45 is a standard thread size used by many manufacturers, including DWK Duran and SCAT, ensuring these safety caps fit most 100 mL to 2000 mL glass laboratory bottles.
3. Why are SCAT unbowed connectors used in solvent handling?
SCAT connectors provide a secure, straight path for tubing, preventing kinks or "bowing" that can restrict flow or cause leaks at the bottle connection point.
4. Are the 4-port HPLC caps supplied fully assembled?
Models like the DWK Duran GL 45 HPLC Screw Cap (4-Port Assembled) come ready for use, including the necessary inserts to secure multiple lines immediately.
