Liquid Media

Ready-to-use media considerably reduce the preparation time in quality control laboratories and also effectively reduce the risks of cross contamination. GVS is cooperating closely with quality assurance managers in the industry in the development of its own media and test kits.  This intensive product development has produced a range of products that is being used to monitor production plants and conduct microbiological checks on raw materials through to final product release in laboratories in more than 40 countries.

Features and Benefits:

• Wide range of products satisfies even special customer requirements
• Optimal media stability, sterility, and reproducibility
• Less time-consuming, higher productivity
• Batch-specific quality certificate in each pack

Applications Microbiological analysis of: 

• Drinking water
• Surface water
• Recreational water
• Purified water

Pseudomonas Broth

Pseudomonas aeruginosa is characterized by the production of pyocyanin (a blue green, water soluble, non-fluorescent, phenazine pigment) which is stimulated by the inclusion of magnesium chloride and potassium sulfate in the broth. Irgasan, an antimicrobial agent, selectively inhibits gram-positive and gram-negative bacteria other than pseudomonads. Glycerol both serves as an energy source and helps in the promotion of pyocyanin.
