Autosampler Vial

13-425 Sample Vial and Cap and Septa

The 13-425 autosampler vial is a standard ND13mm open-top screw-top vial made from borosilicate glass, designed for reliable sample storage and injection in HPLC and GC analysis. It is compatible with Agilent, Shimadzu, and Waters autosamplers. The vial features a flat bottom for stable placement in inserts and is available in clear or amber glass with or without a writing area. Pre-assembled caps and pre-slit PTFE/silicone septa reduce handling and contamination risk during sample preparation.

Standard ND13mm screw-top design ensures compatibility with Agilent, Shimadzu, and Waters autosamplers
Borosilicate glass construction resists chemical attack and thermal shock during routine lab use
Flat bottom design provides stable positioning in autosampler inserts and reduces vial tipping
Pre-slit PTFE/silicone septa allow easy needle penetration without additional tooling

Where It Is Used

Applications And Buyers

Application Scenarios

Storing and injecting HPLC and GC samples in pharmaceutical QC laboratories
Preparing environmental and food matrix samples for residue analysis with light-sensitive compounds
Handling high-throughput sample batches in contract research organisations
Using in routine analysis where consistent vial geometry and sealing performance are required
Supporting method transfer between different autosampler platforms due to standard ND13mm fit

Who It Is For

Pharmaceutical and biotech labs requiring consistent vial performance across multiple HPLC and GC methods
Environmental and food testing labs handling light-sensitive or volatile analytes
Contract laboratories managing high sample volumes with tight turnaround times
Lab distributors sourcing a standard vial format with multiple configuration options
OEM partners needing a reliable, pre-assembled vial system for private-label packaging

Problems It Solves

Vials tipping in autosampler inserts due to uneven or domed bottoms
Needle damage or poor seal integrity from non-pre-slit or poorly designed septa
Contamination from repeated handling during cap and septa assembly
Inconsistent fit with autosamplers due to non-standard vial neck dimensions
Loss of sample integrity due to light exposure in clear vials containing photosensitive compounds
Delays in sample preparation caused by manual septa cutting or cap assembly
Inability to identify samples quickly when labels are lost or not applied

Comparison

Compared With The Alternatives

Versus Vials with domed bottoms

The flat bottom ensures stable placement in autosampler inserts, reducing the risk of tipping during injection

Versus Non-pre-slit septa

Pre-slit septa allow consistent needle penetration without additional tooling or risk of septa damage

Versus Separate cap and septa assembly

Pre-assembled components reduce handling and contamination risk during sample preparation

Versus Standard glass vials without writing area

The writing area option enables direct sample identification, reducing label loss and mislabelling

Use Guide

How To Use It

Select clear vials for general use or amber vials for light-sensitive samples
Use vials with a writing area when direct sample identification is required
Ensure the septa is pre-slit and properly seated before placing the cap
Insert the vial into the autosampler insert with the flat bottom down
Use a needle with a sharp tip to pierce the pre-slit septa cleanly
Avoid over-tightening the cap to prevent damage to the septa or thread
Discard the first few microlitres of sample if the method is sensitive to septa leachables

FAQ

Questions Buyers Ask

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

Yes. The 13-425 neck type is a standard ND13mm open-top screw-top design, compatible with Agilent, Shimadzu, and Waters autosamplers

What is the difference between the clear and amber vials?

Clear vials are suitable for general use. Amber vials protect light-sensitive samples from degradation

Can I use these vials for volatile or aggressive solvents?

Yes. Borosilicate glass is resistant to most solvents and temperature changes encountered in HPLC and GC analysis

Do you offer OEM services for private-label packaging?

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

What is the packing quantity?

All vials are packed in PP boxes of 100 units per pack

How long does delivery take?

Due to regular stocking, delivery is available within 3 to 5 days

Are the septa pre-slit?

Yes. The septa are pre-slit for easy needle penetration without additional tooling
