FAQs

Q1: Is this GL45 feeding cap compatible with all standard reagent bottles?

A: Yes, absolutely. Our GL45 feeding cap is designed to meet standard international GL45 specifications. Consequently, it fits perfectly on most GL45 threaded glass reagent bottles, such as those from Schott, Corning, and other major laboratory glassware brands. This ensures a secure and standardized fit for your fluid transfer setups.

Q2: Can the entire assembly be safely sterilized in an autoclave?

A: Yes. We use premium 304 stainless steel and high-grade PBT to ensure maximum thermal resistance. The entire GL45 feeding cap assembly is fully autoclavable at temperatures up to 180°C (356°F). Therefore, you can maintain a sterile environment for sensitive sampling or cell culture media distribution without damaging the cap or its connectors.

Q3: How does this cap prevent the evaporation of volatile HPLC mobile phases?

A: Protection against evaporation is a key feature of our design. Each GL45 feeding cap utilizes a high-sealing silicone gasket and a 3mm thickened plate with double-sided welding. This combination creates an airtight, leak-proof seal. As a result, it effectively prevents hazardous vapor escape and protects your mobile phase from external contamination.

Q4: Which port configuration (1, 2, 3, or 4) should I choose for my application?

A: This depends on your specific workflow.

1-2 Ports are typically ideal for simple sampling or feeding.
3-4 Ports are perfect for complex HPLC mobile phase setups where you need simultaneous feeding, venting, or multi-channel distribution.
Furthermore, we offer three barbed connector sizes (Small, Medium, Large) to match your specific silicone tubing diameters.
