Materials

According to the high requirements of chemical analyses, especially with regard to reproducibility combined with high detection sensivity, the container material for the respective samples is of great importance. In general, for this purpose vials made from glass are used. The hydrolytic resistance of the glass can be taken as a measure for its chemical inertness. Determination of the hydrolytic resistance and the resulting classification of a glass grade are governed by the German and international industrial standard DIN 12111 / ISO 719. Glass grades are classified in hydrolytic classes .
We supply vials from the following classes:

1st hydrolytic class

Glass grades made from borosilicate, such as DURAN®, Pyrex®, Fiolax® and others belong to this group. Glass of this class, which is often called neutral glass, has a very good chemical resistiance towards acid and neutral solutions. The relatively low alkali content permits good values for the resistance towards alkaline solutions, too. If nothing else is stated, the vials of our programm are made from glass of the 1st hydrolytic class (manufactured in accordance with Eu.Ph. VI Ed., U.S.P. XXV Ed., DAB-10, Ph. Jap. 13).

3rd hydrolytic class, AR glass

Glass of this class, also called soft glass or lime soda glass, has a mediumhydrolytic resistance. For longtime storage of aqueous and especially alkaline-aqueous samples (for example to use them repeatedly) it
is not recommended. Nevertheless, it can be used for many analytical applications.

We supply the following types of sample bottles:

vials with crimp top and corresponding caps
screw thread vials and srew caps
sealing disks for individual combinations of cap and seal

Except for a few frequently used combi packs, vials and caps can be ordered separately, thus allowing a wide range of possible combinations.

Advantages of the DIN crimp top:

Crimp top vials are available with 3 differnt rim heights: 3 mm, DIN crimp top with 3,6 mm and 4mm. When using only one crimper, tedious adjustments for the different heights are necessary. The standardized DIN crimp top avoids this problem. The rim height in accordance with DIN 58366 should be 3,6 +/- 0,2 mm. We supply vials with DIN crimp top for volumes above 5 ml.

Except where explicitly mentioned, caps with sealing disks are supplied assembled, i. e. ready-to-use. Seals below the caps are shown for illustration purposes only, and they are pictured upside down.
For tightly closing crimp top vials manually, you need an appropriate crimper, for opening the corresponding opening pliers are used. If you have e. g. sample vials with 20 mm rim diameter and the proper crimp caps (e. g. N 20 TB/oA), you can use crimpers N 20 and opening pliers N 20 OE. The crimpers listed below can be adjusted to the respective rim height with the aid of a hexagonal key (except for the N8 crimper).
