Autosampler Vial

15-425 Sample Vial and Cap and Septa

The 15-425 Sample Vial & Cap & Septa is a standard screw-top glass vial system designed for reliable sample storage and handling in HPLC and GC autosampler applications. The flat-bottom design ensures stable placement in autosamplers and storage racks.

Pre-assembled caps and septa reduce handling and contamination during sample loading
PTFE/silicone septa are suitable for repeated needle punctures in HPLC and GC autosamplers
Flat-bottom vials provide stable placement in autosamplers and storage racks
Available in 8 ml and 12 ml volumes with clear or amber glass for light-sensitive samples

Borosilicate glass vials formed by precision glass blowing
PTFE/silicone septa die-cut and pre-slit
Caps and septa pre-assembled and verified
Final packing in PP boxes at 100 pieces per pack

Quality Control

Vials inspected for cracks, bubbles, and dimensional consistency
Septa checked for pre-slit integrity and material uniformity
Cap-to-neck fit verified for correct torque and sealing
Pre-assembled units tested for leakage under pressure
Packing verified to match part number and quantity

Comparison

Compared With The Alternatives

Versus Vials with loose caps and septa

Pre-assembled units reduce handling and contamination risk during sample loading and autosampler use.

Versus Standard glass vials without flat bottoms

Flat-bottom design prevents tipping in autosamplers and storage racks, improving workflow reliability.

Versus Non-pre-slit septa

Pre-slit septa allow consistent needle penetration without excessive force or needle damage.

Versus Plastic vials

Borosilicate glass offers lower extractables and better chemical resistance compared to plastic, critical for HPLC and GC analysis.

Use Guide

How To Use It

Select clear glass for general use or amber glass for light-sensitive samples
Use 8 ml vials for small sample volumes and 12 ml for larger or viscous samples
Ensure the septum is pre-slit and properly seated before inserting the needle
Apply moderate pressure when piercing the septum to avoid needle breakage
Store vials upright in racks to maintain flat-bottom stability
Replace septa after a set number of injections to prevent leakage or contamination

FAQ

Questions Buyers Ask

What is the neck size of these vials?

The vials have a 15-425 neck size, which is standard for most autosamplers and HPLC/GC systems.

Are the septa pre-slit?

Yes, all septa are pre-slit for easier and more consistent needle penetration.

Can I use these vials for HPLC analysis?

Yes, the PTFE/silicone septa and borosilicate glass make them suitable for HPLC and GC applications.

What is the difference between clear and amber vials?

Clear vials are for general use; amber vials protect light-sensitive samples from degradation.

How are the vials packed?

Each pack contains 100 vials with pre-assembled caps and septa in a PP box.

Do you offer OEM services?

Yes, the Microlab OEM division supports private-label printing, custom packaging, and contract manufacturing.
