Autosampler Vial

Head Space Vials

Head space vials are designed for consistent, secure sealing in headspace analysis and gas chromatography mass spectrometry. Available in 10 ml and 20 ml volumes with flat or round bottoms, they support both crimp and screw top configurations. The vials are made from borosilicate glass and are compatible with major instrument brands including Agilent and Gerstel. Their construction minimises sample contamination and ensures reliable performance across pharmaceutical, environmental, forensics, biopharmaceutical, and metabolomics applications.

Flat and round bottom options allow compatibility with a variety of headspace instruments
Crimp and screw top configurations provide flexibility for different sealing and handling needs
Borosilicate glass construction resists thermal and chemical stress during high-temperature analysis
Clear and amber vial options protect light-sensitive samples from degradation

Comparison

Compared With The Alternatives

Versus Plastic vials

Borosilicate glass has lower extractables and better thermal stability than plastic, which is critical for GC-MS and high-temperature headspace analysis.

Versus Standard glass vials without sealing verification

Microlab vials are tested for consistent sealing and compatibility with major autosamplers, reducing the risk of sample loss during analysis.

Versus Single cap type only

Offering both crimp and screw top options allows labs to match their existing instrument setup without changing protocols.

Versus Generic vials from unbranded suppliers

Microlab vials are dimensionally consistent and tested for compatibility with Agilent, Gerstel, and similar platforms, reducing instrument downtime.

Use Guide

How To Use It

Select crimp or screw top based on your autosampler's sealing mechanism
Choose clear vials for general use and amber vials for light-sensitive samples
Match septa thickness and material to your instrument's injection requirements
Use 1.3 mm septa for low-volume injections and 3 mm for high-pressure or long-term storage
Ensure cap is tightened securely to prevent leaks during heating and pressurisation
Do not exceed recommended temperature limits for the glass and septa materials
Store vials in a dry, cool environment to prevent contamination and seal degradation

FAQ

Questions Buyers Ask

Are these vials compatible with Agilent and Gerstel autosamplers?

Yes, the vials are dimensionally consistent with major brands including Agilent and Gerstel, and have been tested for reliable performance in their systems.

What is the difference between crimp and screw top vials?

Crimp top vials use a metal cap secured by crimping, offering a hermetic seal. Screw top vials use a threaded cap with a septum, allowing repeated access without resealing.

Can I use amber vials for all samples?

Amber vials are recommended for light-sensitive samples. Clear vials are suitable for most general applications where UV exposure is not a concern.

What septa types are available?

Available septa include blue PTFE/white silicone (17.5 mm), natural PTFE/natural silicone (3 mm), red PTFE/white silicone (1.3 mm), and natural PTFE/butyl rubber (3 mm).

How are the vials packed?

All vials are packed in PP boxes with 100 pieces per pack, and each pack is labelled with the part number and configuration.

Can you supply these under our own brand?

Yes, the Microlab OEM division offers private-label printing, custom packaging, and OEM contract manufacturing for vials and closures.
