Exceeded volume options in one single vial

Are you convinced that your micro sampling vial is the best option on the market?

Improve the productivity of your lab with just one vial with our new sampling option - from as low as 4 µl to up to 1,4 ml.

Micro-V Tapered MicroVials (Flute vials)

Although 12x32mm flat bottom 2mL vials are still the mainstay of the chromatography vial market, an increasing number of small volume sampling options have led to more flexibility when working with limited amounts of sample.

Working with smaller sample volumes requires the use of a Microsampling Vial

Definition: Microsampling is a technique where nearly all of the sample added to a vial can be recovered for injection into a chromatograph.

Thermo Scientific Micro-V Tapered MicroVial

One method to reach this goal is to change the internal shape of the vial for improved sample recovery
Thermo Scientific Micro-V Tapered MicroVials (Flute vials) offer large total sample volumes up to 1.4mL with near complete recovery with less than 4µL residual sample volumes possible due to the unique internal design
Available in clear and amber 1^st hydrolytic class glass
As 9mm screw thread and 11mm crimp version
Compatible with all standard autosampler racks using 2mL vials due to identical outer dimension and height
Excellent heat transfer compared to vials with microinserts e.g. in case of derivatization or internal reactions

The biggest benefit in the lab is the ability to work with frequently changing volumes from 1.4mL down to 20µL without changing the vial providing constant results and excellent reproducibility from injection to injection!

Thermo Scientific WebSeal 96 well re-sealing tape with 3 layers and no adhesive at the cavity area

Do you face any of these issues with your tape?

Your tape is not resistant to organic solvents
The tape does not reseal after puncture
The needle lifts the tape or plate
The adhesive contaminates your sample

If so, we are able to offer the right solution to improve your flexibility and reproducibility working with well plates our 96-well plate compatible tapes for chromatography offer:

Chromatography optimized material
Pre-slit but high resealability
Polar organic solvent stability
Acid stability
No glue or adhesive in the cavity area

Why are well plates important for chromatography?

Samples coming from a pipetting robot and/or biological treatment must not be transferred to a vial to be chromatography autosampler compatible
Although standard microtiter plates are still the mainstay on the market, sample volumes decrease more and more and therefore the demand for plates handling very small sample volumes increases.
