For the products presented in the site Skonx& CO, the manufacturers of glass endowments for volume measurements are: Hirschmann Laborgerate Certificate with ISO 9001, that refers at the international standards of quality respected during the production. Choosing from these products it can rely on a steady quality and execution according standards DIN. As for the glass products that are not presented in the catalogue, we can assure their supply according the necessities and possibilities.

Utensils for volume measurement with class A…of precision. Making and calibration of products for volume measurement is made without man’s interference, by means of automatic systems. These automatic systems make steady auto tests, are well-informed excluding almost completely the errors. Besides, it is made verification at random sampling from the lots of manufacturingDemand offer

Utensils for the volume measurement with quality certification, on the products are written all the information referring at the quality certification;
- The volume, value of a division and tolerance;
- Temperature of calibration;
- Class of precision A or AS;
- Time for complete emptying
- The H letter shows the conformity (certificate of conformity), it shows lot’s certification;
- Year of making and lot series. It is a brand mark (emblem) like a circle with letters and the date of making in center. The number and their arrangement shows the lot’s series;
- The emblem of producer and the native country. The enumerated products are made by HIRSCHMANN GmbH in Germany.
Now, glass lab utensils are made especially from glass Boro 3.3, that is characterized by an exceptional thermal and chemical resistance. Thermal resistance: because of the dilatation value reduced, borosicate glass resists well at abrupt temperature variations, almost up to 5000 A, A C. Chemical resistance: this type of glass resists at the majority of chemical substances (for ex. watery solutions, acids, organic solvents).By increasing pH, diminishes the chemical resistance, but even in case of very basic solutions, corrosion at glass surface is insignificant, especially at room’s temperature.

The borosicate glass is attacked by the fluorhydric acid the fluoride agents. Of course, it doesn’t recommend the use of this type of glass at heating the alkaline metals in solid state.Demand offer
