ND9 9mm Short Thread Vials that works with all autosamplers

The Universal Choice: Why Should You Upgrade to N

The ND9 Short Thread Vial is meant to take the place of both Crimp Top and older Screw Top (ND8) vials. The "Wide Opening" design is the best part because it gives autosampler needles a 40% larger target area. This greatly lowers the chance of needles getting bent, especially in modern autosamplers that work quickly.

With just a half-turn, the "Short Thread" lets you seal or remove the cap. This is not only comfortable for lab workers to use, but it also works with robotic arm grippers (like Agilent) that need a certain shape for the cap to be able to move it.

Specialized Variants for Critical Analysis

We offer more than just regular glass for trace analysis, small samples, and ion chromatography.

Silanized (Deactivated) Vials

Models V917-S and V927-S: Standard glass surface silanols can adsorb samples for very sensitive analysis, like proteins, phenols, and pesticides. Our Silanized vials have a deactivated surface that makes sure that 100% of the sample is recovered and counted correctly.

High Recovery Vials

Models VR913 and VR935: These vials have a special conical base inside that holds 30μL of liquid. They let you get the most sample out of them without needing separate inserts, which is great for small samples (less than 100μL).

Solution Category	Part No.	Problem / Issue	Core Solution	Key Benefit / Advantage
Anti-Adsorption (Silanized)	V917-S / V927-S	Proteins and peptides are sticking to the glass walls, which is giving wrong results.	Organosilane deactivated the surface.	Almost 100% recovery of polar compounds; prevents data from being skewed.
Limited Volume (High Recovery)	VR913 / VR935	The sample volume is less than 100 μL, like blood from a newborn or forensic evidence.	The vial has a built-in "V-shape" base.	The residual volume is less than 5 μL, so there is no need for separate spring inserts.
Metal-Free Analysis (Polypropylene)	VP923 / VP945	Samples that have a lot of heavy metals or a high pH.	Polypropylene (PP) that is safe for medical use.	Ion Chromatography (IC) needs chemicals that are stable in strong bases and don't have ions.
