Autosampler Vial

8-425 Sample Vial and Cap and Septa

The 8-425 autosampler vial system is a standard ND8mm open-top screw glass vial designed for routine HPLC and GC analysis. It features a uniform flat bottom for stable placement in autosampler inserts, and is compatible with Agilent, Shimadzu, and Waters autosamplers. Pre-assembled caps and septa reduce handling and contamination risk, while PTFE/silicone septa provide reliable sealing and needle puncture performance. Available in clear and amber glass with optional writing areas on the vial body.

Standard ND8mm open-top screw design ensures compatibility with Agilent, Shimadzu, and Waters autosamplers
Uniform flat bottom provides stable seating in autosampler inserts, reducing run-to-run variability
Pre-assembled caps and septa minimize handling and contamination during sample loading
PTFE/silicone septa offer consistent sealing and easy needle puncture, reducing septa carry-over

Where It Is Used

Applications And Buyers

Application Scenarios

Routine HPLC and GC sample preparation in pharmaceutical and environmental testing labs
High-throughput analysis where consistent vial seating and reliable septa performance are critical
Sample storage and transport in labs using autosamplers with tight space constraints
Analysis of light-sensitive compounds requiring amber vials to prevent degradation
Laboratories standardising on a single vial format across multiple instrument platforms

Who It Is For

Pharmaceutical QC labs running high-volume HPLC and GC methods with tight throughput targets
Environmental and food testing labs handling diverse sample matrices requiring consistent vial performance
Contract research organisations managing multiple instrument types and needing interchangeable vials
Lab distributors sourcing a complete, pre-assembled vial system with consistent quality and delivery

Problems It Solves

Vials not seating properly in autosampler inserts due to uneven or domed bottoms
Septa fragments contaminating samples when using non-pre-slit or poorly designed septa
Inconsistent needle puncture force leading to needle damage or poor injection reproducibility
Need to source vials, caps, and septa from separate suppliers with different quality control
Light-sensitive samples degrading in clear vials during storage or analysis

How It Is Made

Manufacturing And Quality Control

Manufacturing Process

Glass vial manufacturing and annealing
Die-cutting and assembly of septa
Pre-assembly of caps and septa onto vials
Quality inspection of assembled units
Packing in PP boxes at 100 pieces per pack

Quality Control

Septa checked for uniform thickness and pre-slit alignment
Pre-assembled units tested for sealing integrity and needle puncture performance
Final inspection against packing and part number accuracy

Comparison

Compared With The Alternatives

Versus Vials with domed bottoms

The flat bottom ensures consistent seating in autosampler inserts, reducing run-to-run variability and preventing vial tilt during injection.

Versus Separate caps and septa

Pre-assembled units reduce handling, lower contamination risk, and ensure correct pairing of cap and septa.

Versus Non-pre-slit septa

Pre-slit septa reduce needle penetration force and lower the risk of septa fragments entering the sample.

Versus Single-use vials from multiple suppliers

A single source for vials, caps, and septa ensures consistent quality, compatibility, and delivery.

Use Guide

How To Use It

Select clear vials for visual inspection of samples or amber vials for light-sensitive compounds
Use vials with writing areas when labelling samples directly on the vial body
Choose pre-slit septa for easier needle penetration and reduced needle wear
Use bonded PTFE/silicone septa for applications requiring higher sealing integrity
Ensure the vial is seated flat in the autosampler insert before injection
Do not over-tighten the cap to avoid damaging the septa or deforming the cap

FAQ

Questions Buyers Ask

Are these vials compatible with Agilent, Shimadzu, and Waters autosamplers?

Yes. The 8-425 neck type and ND8mm design are standard across Agilent, Shimadzu, and Waters autosamplers.

What is the difference between the clear and amber vials?

Clear vials allow visual inspection of samples. Amber vials protect light-sensitive compounds from degradation.

Do you offer vials with writing areas?

Yes. Models SV0812C and SV0812A include a writing area on the vial body.

What septa types are available?

Available septa include PTFE/silicone, pre-slit, bonded PTFE/silicone, and white PTFE (0.25 mm).

Can I order these with my own branding?

Yes. The Microlab OEM division supports private-label packing and custom branding for bulk orders.

How are the vials packed?

Standard packing is 100 pieces per pack in PP boxes. Pre-assembled caps and septa are included.
