<h2>Frequently Asked Questions</h2>
<p>&nbsp;</p>
<h3>1. What is the purpose of a pressure compensation set?</h3>
<p>The DWK Duran pressure compensation set allows air to enter the bottle as liquid is withdrawn, preventing a vacuum that could stall your HPLC pump, while keeping dust out.</p>
<h3>2. Will GL 45 caps fit all laboratory bottles?</h3>
<p>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.</p>
<h3>3. Why are SCAT unbowed connectors used in solvent handling?</h3>
<p>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.</p>
<h3>4. Are the 4-port HPLC caps supplied fully assembled?</h3>
<p>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.</p>
