2ml HPLC VIALS/CLOSURES/KIT

Types of 2 mL HPLC Closure Kits Available

HPLC setups aren’t one-size-fits-all. That’s why the availability of multiple kit formats is essential. At Borosil Scientific, we offer three primary formats of 2ml vials and closure kits, each tailored to different instruments, workflows, and user preferences. All vials are made from USP Type I borosilicate glass, using 49-Expansion and 33-Expansion glass for clear vials and 54-Expansion glass for amber vials, and are compatible with all major HPLC systems.

VC02S – 2ml Screw HPLC Vial & Closure Kit

• Dimensions: 9mm × 12 × 32 mm
• Thread: 9mm Screw Top
• Design: Secure, easy-to-use threaded cap
• Material: High-clarity borosilicate glass (33-Expansion and 49-Expansion), consistent with other variants

VC02 – 2ml Snap HPLC Vial & Closure Kit

• Dimensions: 11mm × 12 × 32 mm
• Cap: Snap Top Clear Vial
• Closure: Non-slit white PP cap
• Septa: PTFE-Silicone, chemically inert and ultra-pure

VC02C – 2ml Crimp HPLC Vial & Closure Kit

• Cap Type: Crimp Top
• Advantage: Ideal for systems requiring tighter seals, especially for high-pressure setups
• Volume: True 2.0 mL fill

These kits are designed not just for dimensional compatibility, but for repeatable performance and low extractable interference. That includes 100% dimensional inspection and leak-proof septa designed for zero compromise during analysis.

Key Features of the 2 mL HPLC Closure Kit

What sets Borosil Scientific’s HPLC vials apart from standard offerings is our attention to detail. Every material, every fit, every seal is optimised to serve analytical labs working with tight tolerances.

Material & Manufacturing

• Borosilicate USP Type I Glass (33-Expansion, 49-Expansion and 54-Expansion): Offers high thermal stability and minimal leachable elements. Suited for critical applications across pharmaceuticals, food analysis, and environmental labs.
• PTFE-Silicone Septa: This makes sure that the vials are chemically inert and resistant to coring, maintaining seal integrity over multiple injections.
• Low Leachables Profile: Particularly relevant for sensitive LC-MS or trace analysis. The glass is tested for alkali content and silicon leaching to ensure minimal background interference.
• GMP-Compliant Production: All kits are manufactured in ISO 15378-certified facilities. A full testing and documentation trail is available to support quality audits and root cause investigations.

Mechanical Integrity

• Dimensional Accuracy: Each vial undergoes a 100% inspection process to ensure repeatability during automated handling and processing.
• Leak-Proof Closure: Regardless of the cap style, whether crimp, screw, or snap, Borosil Scientific’s kits ensure that there is no leakage under pressure.

Compatibility Across Systems

Most autosamplers, even those from major OEMs, can accommodate all three formats (snap, crimp, and screw). That way, you won’t have to worry about this one thing when you switch between systems or grow your business. The consistent 12 x 32 mm size makes it easy to fit, and the 9 mm and 11 mm cap sizes fit standard industry trays. Whether you’re upgrading to newer platforms or using older equipment, these vials can be easily added without the need for additional adapters or changes to the existing setup.

Conclusion

Ultimately, the selection of the appropriate vial is a critical factor in ensuring the accuracy and reliability of HPLC analysis. At Borosil Scientific, every HPLC test vial is manufactured to meet strict dimensional and material standards. Whether you’re using an automated sampler or a manual injection system, our HPLC sample vials deliver reliable results batch after batch. We guide you through the types, features, and key considerations when selecting a 2ml vial and closure kit, and explain why these kits matter more than many realise.
