Conformity certification • How to recognize the conformity certification? The instruments carry the symbol of conformity - a stylized "H" as well as the code of the issuer of the conformity certificate. For Disposables the "H" appears on the packaging and/or the accompanying documents. • What does conformity stand for? Conformity means compliance of an instrument with the German Rules for Official Certification (Eichordnung, Annex 12). The conformity certification procedure is described by DIN 12 600. The "Exemption from Certification Act" has become obsolete. • Which instruments must be...

The properties of the borosilicate glass we work with: DURAN represents the internationaly estabilished type of borosilicate glas 3.3 (DIN-ISO 3585) and the major international standards as the English, American and French. Highest possible chemical restance, minimum thermal expansion as well as the thereby conditioned high thermal shock resistance are its essential characteristics. This optimum physical and chemical behaviour predisposes DURAN to the application in laboratories and for large industrial installations in chemical plant systems. It is considered moreover to be an all-round...

Chemical properties of DURAN® DURAN is highly resistant to water, neutral and acid solutions, concentrated acids and their mixtures, as well as to chlorine, bromine, iodine and organic matters. Even during extended periods of reaction and at temperatures above 100 °C, its chemical resistance exceeds that of most metals and other materials. By the action of water and acids only small amounts of mainly monovalent ions are eliminated from the glass. On the glass surface, a very thin, almost non-porous silica gel layer then forms inhibiting any further attack. Only hydrofloric acid, very hot...

Due to so many advantages as breakage resistance, low weight, very good chemical resistance and their good physical properties laboratory instruments made from plastics have nowadays their proper place in laboratories. Which plastics can be used in the laboratories is dependend of well-informed evaluation of the user. The below mentioned recommendations of the raw-material manufacturers are intended only as a hint to find a decision and can not replace a suitability test by the user. Internationally used abbreviations and standard norms of plastic resins (according to DIN 7723/7728) Since...
