Autosampler Vial

Storage Vials

Storage vials are designed for long-term packaging and transportation of pharmaceutical intermediates, high-value chemicals, reagents, biological samples, cosmetics, essences, and oils. They feature a screw-top closure with a PTFE/silicone septum for reliable sealing and compatibility with autosampler systems. Available in clear and amber glass with multiple sizes from 2 mL to 60 mL, they support stable storage under light-sensitive and inert conditions.

Clear and amber glass options protect light-sensitive samples from degradation during storage and transport
Screw-top design with PTFE/silicone septum ensures a tight seal to prevent leakage and evaporation
Multiple sizes from 2 mL to 60 mL allow selection based on sample volume and storage duration
Consistent thread compatibility (9-425, 13-425, 15-425, 18-400, 24-400) across all vial types for interchangeable use

Where It Is Used

Applications And Buyers

Application Scenarios

Storing pharmaceutical intermediates and active ingredients in a controlled environment before further processing
Preserving biological reagents and enzyme solutions for extended periods without degradation
Holding high-value chemical reagents in laboratories where contamination and evaporation must be avoided
Transporting essential oils and cosmetic formulations between production and testing sites
Maintaining sample integrity in environmental and food testing labs during long-term storage

Who It Is For

Pharmaceutical and biotech labs requiring stable, long-term sample storage for R&D and QC
Chemical and specialty materials manufacturers handling sensitive reagents and intermediates
Contract testing labs managing large volumes of samples with strict storage and traceability needs
Laboratory distributors sourcing consistent, high-performance vials with standardised packaging
OEM partners needing private-label vials and closures for branded consumable lines

Problems It Solves

Sample loss due to evaporation from poorly sealed vials during long-term storage
Degradation of light-sensitive compounds when stored in non-amber or non-UV-protected containers
Inconsistent thread fit between vials and caps leading to leaks or seal failure
Need to source multiple vial types from different suppliers with varying pack sizes and closure systems
Difficulty in maintaining sample traceability and integrity across storage and autosampling workflows

Comparison

Compared With The Alternatives

Versus Plastic vials

Glass vials offer lower extractables and better chemical resistance than plastic, which is critical for long-term storage of reactive or sensitive compounds

Versus Vials with adhesive-sealed caps

Screw-top design allows repeated access without seal degradation, unlike adhesive-sealed caps that lose integrity after one puncture

Versus Non-amber vials for light-sensitive samples

Amber glass blocks UV and visible light, preventing photodegradation of sensitive compounds that clear glass cannot protect

Versus Vials with non-standard thread sizes

Standardised thread sizes (9-425, 13-425, etc.) ensure compatibility with most autosamplers and lab racks

Use Guide

How To Use It

Select clear glass for samples not sensitive to light; use amber glass for UV-sensitive compounds
Match the vial size to the sample volume to avoid overfilling or underutilisation
Use closed caps for long-term storage to prevent evaporation and contamination
Use open caps when frequent access is needed and the sample is stable
Ensure the septum type matches the application: PTFE/silicone for repeated punctures, PE for non-reactive samples
Store vials upright in a stable rack to prevent breakage and ensure consistent positioning

FAQ

Questions Buyers Ask

What is the difference between clear and amber glass vials?

Amber glass blocks UV and visible light, protecting light-sensitive samples. Clear glass is suitable for samples not affected by light exposure.

Can I use these vials for autosampler injection?

Yes. The vials are designed with standard thread sizes (9-425, 13-425, 15-425, 18-400, 24-400) compatible with most autosamplers.

What septum types are available?

PTFE/White Silicone, Natural PTFE/Natural Silicone, and PE septa are available depending on the cap model.

How many vials are in each pack?

Each pack contains 100 pieces. This standard packing reduces handling and inventory complexity.

Do you offer private-label vials?

Yes. The Microlab OEM division supports private-label printing, custom packaging, and custom cap configurations.

Are the caps compatible across different vial sizes?

No. Each vial size uses a specific thread (e.g., 9-425, 18-400), so caps are not interchangeable across sizes.
