Abstract

The present invention discloses a washing agent special for labs, which is liquid washing agent prepared by mixing the components of dodecyl benzene sulfonate, trolamine, 3,4- xylene ichthyodin, fatty alcohol-polyoxyethylene ether, EDTA-4Na, oxyful, natrium boricum, prolease, activated carbon powder and the like. All common stains in a washing process of glass vessels in the labs, such as metal oxide, insoluble metal irons, macromolecular esters, animal vegetable greases, modified coagulated protein of various culture vessels for culture mediums, grease stain and the like, can be rapidly cleared, and the present invention has the advantages of simple and safe use, low cost, small causticity for skins and instruments, small environmental pollution and the like.

Description

technical field [0001] The invention relates to a detergent, in particular to a laboratory-specific glassware detergent. Background technique [0002] The detergents currently used in the laboratory basically cannot meet the best washing efficiency of glassware, such as three-effect heat source inactivator, special detergent for glassware, and sometimes there are still detergent residues after cleaning glassware. The detergent is not strong enough to achieve the special purpose of cleaning laboratory glassware. In addition, efforts should be made to remove hard-to-clean items such as protein coagulation residues. Contents of the invention [0003] The main purpose of the present invention is to provide a special detergent for laboratories, which has a good cleaning effect on various stains, and has the advantages of simple and safe preparation and use, low cost, low corrosion to skin and instruments, and small environmental pollution. . [0004] Another object of the pr...
