Even at a simple blood test it is extremely important to apply sterile laboratory glassware not to mention other medical tests, laboratory experiments and testing chemical reactions. Indeed, the results can be greatly affected by the smallest speck of dust or anything else. One of the biggest advantages of laboratory glassware is the easy sterilization and the lack of reactivity.
Our business has been involved in the production and marketing of laboratory glassware since 1992. During the production of laboratory glassware our experts use DURAN glass tubes and rods produced by the high quality representative Czech factory SIMAX and the German SCHOTT factory.
Our borosilicate based laboratory glassware resists even the most extreme conditions. Due to the presence of borosilicate our laboratory glassware has a massive heat resistance, excellent tolerance to extreme temperature changes, its chemical and mechanical resistance is exceptional.
Our laboratory glassware has resistance to various acids and alkalis, pickles, organic compounds, also the halogen chlorine and bromine.
FIXED laboratory glassware has an allowed, brief, maximum temperature resistance of 500 ° C.
Tolerance to temperature change compared to the normal bottles is extreme, linear coefficient of thermal expansion: (20/300° C) 3,3*10-6 1/K.
The borosilicate laboratory glassware in the visible spectrum does not show significant absorption, therefore DURAN laboratory glassware seems clear and uncoloured, however,,en,nm,,en, of greater thickness it appears greenish. If required, the laboratory glass surface can be pigmented brown with diffusive ink, allowing work with sensitized materials. The coloured glass absorption peak is around 500 nm; in the range of 310-2200 nm DURAN absorption is negligible.
