Autosampler Vial

11mm Snap Top Autosampler Vials

11mm Snap Top Autosampler Vials are standard ND11mm snap-top glass vials designed for routine HPLC and GC sample storage and injection. They are compatible with Agilent, Shimadzu, and Waters autosamplers. The vials feature a flat bottom for stable placement in inserts and are available in clear or amber glass with or without a writing area. Pre-assembled caps and septa reduce handling and contamination risk, while PTFE/silicone septa provide reliable sealing for volatile and reactive samples.

11mm snap-top design ensures consistent fit with Agilent, Shimadzu, and Waters autosamplers
Flat bottom provides stable positioning in autosampler inserts, reducing injection variability
Pre-assembled caps and septa minimize handling, lowering contamination risk during sample prep
PTFE/silicone septa offer excellent chemical resistance and low extractables for HPLC and GC

Comparison

Compared With The Alternatives

Versus Screw-top vials

Snap-top design allows faster loading and unloading in high-throughput autosamplers, reducing cycle time

Versus Non-pre-slit septa

Pre-slit septa reduce needle wear and ensure consistent puncture force, improving injection reliability

Versus Plastic vials

Borosilicate glass vials have lower extractables and better chemical resistance than plastic, critical for trace analysis

Versus Standard vials without writing area

Writing area enables direct sample labelling, reducing label loss and misidentification risk

Use Guide

How To Use It

Select clear vials for general use and amber vials for light-sensitive samples
Use pre-slit septa for faster needle penetration in automated systems
Ensure the vial is seated flat in the autosampler insert to prevent injection errors
Do not over-tighten the snap cap; a secure but easy-to-open fit is sufficient
Store vials in a clean, dry environment to prevent contamination
Use the writing area to label samples directly when traceability is required

FAQ

Questions Buyers Ask

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

Yes. The 11mm snap-top design matches standard ND11mm dimensions used by Agilent, Shimadzu, and Waters autosamplers.

What is the difference between pre-slit and non-pre-slit septa?

Pre-slit septa allow easier needle penetration with less force, reducing needle wear and improving injection consistency.

Can I use these vials for volatile samples?

Yes. The PTFE/silicone septa provide a tight seal that minimizes loss of volatile compounds during storage and injection.

Do you offer custom packaging or private-label printing?

Yes. The Microlab OEM division offers private-label printing, custom packing formats, and custom septa configurations.

What is the volume capacity of the 2 ml vial?

The 2 ml vial has a nominal volume of 2 ml, with a 12 mm diameter and 32 mm height.
