2ml ND9 screw vials are 40% larger opening than standard narrow opening vials, made from borosilicate glass.

These class 1 laboratory-tested vessels meet ASTM Type 1 and USP Type 1 standards so your lab is secure and you can take comfort in knowing that your measurements are tight. Please also find the below for the right selections.


  • ND9 Plastic vials we have are available for amber and clear. ND9 Plastic Vials are made of non-disintegrating polypropylene as a special spin-cast process to ensure maximum strength and dimensional accuracy. In combination with closure (fluorine-free), ND9 Plastic Vials are recommended for PFAS analysis.
  • The main difference between Interlocked insert vial and glass insert is whether it is fused or not. Of course, this fusion eliminates the movement of the insert during shipment, preventing contamination from bacteria around the fused seam from entering the package.
  • Available in unique packaging designed to reduce vial breakage.
  • If you’re able to prevent vacuum build-up from inside of your vial, then pre-slit septa are the best option for chromatography.
  • High recovery vials made from 1st hydrolytic class glass keep your samples safe and secure. With a conical well, you get the best possible chance of preserving and maximizing samples and chemical compounds for further use and research after experiments.
  •  Glass integrated vial was welded with a glass insert (conical insert, 250ul) during the manufacturing process. The insert is fixed and allows for the injection of solutions to be done more conveniently. As an alternative, inserts can be purchased independently, which means that they can be manually placed into vials.
  • PP integrated vial is made up of Polypropylene (PP), a non-reactive plastic that can be used to replace glass where it is not suitable. Due to the one-piece molding, it cannot be separated.  Maximum volume is 250ul.
  • Recovery vial has a conical design of the bottom of the vial, the arc at the bottom makes it easier for the centrifuge to work. There is a maximum volume of 1.5 mL in this vial, as well as a minimum residual volume of 22 um.
  • The bonded cap is an ideal design for preventing septa drop from the top of the cap. We provide a non-glued design to prevent contamination.
  • Do they make you frustrated when you screw on each cap to the vial? No more frustration. This screwed-up set is ready for your use, safe time and improve efficiency.
