Autosampler Vial

9-425 Sample Vial and Cap and Septa

The 9-425 autosampler vial is a standard ND9mm open-top screw vial designed for routine HPLC and GC sample storage and injection. Pre-assembled caps and septa reduce handling and contamination risk, while the flat bottom ensures stable placement in autosampler inserts. The vial is compatible with Agilent, Shimadzu, and Waters autosamplers.

Pre-assembled caps and septa reduce handling and contamination during sample preparation
Flat bottom design ensures stable placement in autosampler inserts and prevents tipping
Standard ND9mm neck with 9-425 screw top fits Agilent, Shimadzu, and Waters autosamplers
Pre-slit septa allow easier needle penetration without additional tooling or risk of septa debris

Where It Is Used

Applications And Buyers

Application Scenarios

Storing and injecting HPLC and GC samples in pharmaceutical QC laboratories
Handling volatile or light-sensitive samples requiring amber vials and PTFE/septa
Routine sample preparation in environmental and food testing labs with high throughput
Using pre-assembled vials in high-volume screening workflows to reduce analyst error
Storing samples with minimal headspace in autosamplers where consistent geometry is critical

Who It Is For

Pharmaceutical and biotech labs requiring consistent vial geometry for method transfer
Environmental and food testing labs processing large batches of samples with tight timelines
Contract research organisations standardising on a single vial format across multiple instruments
Lab distributors sourcing pre-assembled vials with flexible packaging and branding options
OEM partners needing custom vial configurations for integrated autosampler systems

Problems It Solves

Sample loss or contamination due to loose or improperly sealed vial caps
Inconsistent injection volume caused by vials with uneven or non-flat bottoms
Needle damage or septa debris from non-pre-slit or poorly designed septa
Incompatibility with autosampler platforms due to non-standard neck dimensions
Time lost in manual cap and septa assembly during high-throughput sample prep

How It Is Made

Manufacturing And Quality Control

Manufacturing Process

Glass vial forming and annealing for borosilicate versions
Die-cutting of septa to precise 9mm diameter
Pre-assembly of caps and septa with adhesive bonding or mechanical fit
Inspection of flat bottom and neck geometry
Packing in 100-piece lots with batch traceability

Quality Control

Septa pre-slit integrity checked under magnification
Cap-to-neck fit verified for consistent torque and sealing
Batch traceability maintained for all vials and assemblies
Pre-assembled units tested for leakage under pressure

Comparison

Compared With The Alternatives

Versus Non-flat bottom vials

The flat bottom ensures consistent placement in autosampler inserts, reducing the risk of tipping or misalignment during injection.

Versus Loose cap and septa

Pre-assembled caps and septa reduce handling, contamination risk, and time per sample in high-throughput workflows.

Versus Standard septa without pre-slit

Pre-slit septa allow easier needle penetration and reduce septa debris in the injection stream.

Versus Non-standard necks

The 9-425 screw top with ND9mm neck ensures compatibility with Agilent, Shimadzu, and Waters autosamplers without adapter use.

Use Guide

How To Use It

Select vial material based on sample stability: amber glass for light-sensitive samples, clear glass for general use, PP for disposable or high-volume applications
Use pre-slit septa for faster needle penetration in autosamplers with high sample throughput
Choose PTFE/Silicone septa for routine HPLC applications; pure PTFE for ultra-low extractables
Ensure the vial is placed flat in the autosampler insert to prevent tipping during injection
Do not overfill the vial; leave sufficient headspace for pressure build-up during injection
Replace septa after a set number of injections to avoid septa degradation and carry-over
