The Introduction Of Deactivated Sample Vials

The silicon hydroxyl group with strongly polar on the surface of glass sample vials will adsorb the samples. Based on such reasons, people produce hydrophobic glass surface through silylating the sample vials in order to eliminate the adsorption of the sample vials, which is widely used in protein or pesticide residue analysis.

For instance, glass has high adsorption of protein. The content of pesticide residue is very low when analyzing. Under these circumstances, if the sample vials adsorb the protein in the residue, the error will be great.

In short，the deactivated sample vials is one of the ordinary vials that the inner wall are deactivated. Or the vials are treated by silanization, which produces a hydrophobic surface. Commonly, it is not easy to see the difference from the outside. But it is very obvious when adding liquid into the vials.

There is no concave liquid surface at all. In fact, the material of general sample vials has no problem for the general application.
Compared with the materials of sample vials, there are still many problems with vial pads when using in the experiments. Therefore, we should be careful when choosing vial pads.
