Discs, Strips and Cards

Disks and strips are used in the identification and confirmation of microorganisms. They are easy to use and based on rapid screening methods like the detection of enzymes with chromogenic substrates, indicators, or on complex building reactions. Also, the sensitivity to certain inhibitory substances can be used to identify organisms. The sterility indicator strips are used to monitor sterilization and are important for controlling the sterilization process.

08382 Bacitracin Disks for microbiology    
40405 Hippurate Disks for microbiology    
01869 Hippurate Strips Kit for microbiology Hippurate Strips Test for identification of hippurate hydrolase activity of group B streptococci, Campylobacter jejuni, Gardnerella vaginalis and other microorganisms.
The test is based on hydrolysis of substrate (sodium hippurate) by the bacterial enzyme hippurate hydrolase and production of benzoic acid and glycine. Glycine produced by this enzymatic reaction is detected after 24 hours incubation in reaction with chromogen (ninhydrine) and the blue-purple substance is produced.
04739 Indoxyl Strips for microbiology Acetoxyindol Strips Diagnostic test for the rapid detection of the acetate esterase activity of microorganisms. The test is based on the reaction of free indoxyl groups with oxygen, which results in a color change. Acetate esterase activity is present in Campylobacter spp. and Branhamella catarrhalis. The test is suitable for screening examinations and for the suspect microbial colonies identification. The result of the reaction is read after 3-5 min.
80489 β-Lactamase Strips Kit for microbiology    
49862 Nitrocefin disks for microbiology   For the rapid detection of beta-lactamase enzymes in isolated colonies of Neisseria gonorrhoeae, Moraxella catarrhalis, Staphylococcus spp., Haemophilus influenzae and anaerobic bacteria.
74042 Optochin Disks for microbiology   Optochin Disks has been used to identify pneumococci.
67886 Pyrase Strips for microbiology Pyrrolidonyl Peptidase Strips Pyrase Strips are used for diagnostic test for the rapid differentiation of Enterococci from the group D Streptococci and differentiation of Streptococcus pyogenes from other haemolytic Streptococci.
75744 Tributyrin-Strips for microbiology TRIBU Strips Diagnostic test for the differentiation between Branhamella and Neisseria. The test principle is an enzyme hydrolysis of tributyrin. This reaction causes color change of acidobasic indicator. The result of the reaction is read after 18-20 h.
89788 V-Factor Disks for microbiology Coenzyme-diphosphopyridine-nucleotide Test Disks Use for the presumptive identification of Haemophilus species on the basis of their requirements for X or V factors.
