Matís conducts microbiological research on food, drinking water, medicines, feed and environmental samples, providing specialized, high-quality and fast service and advice to public bodies, food companies, pharmaceutical companies, slaughterhouses and the private sector. 

In addition to microbiological measurements that determine life expectancy using many different methods, Matís' laboratory serves customers with measurements that:

  • Give evidence of hygiene
  • Freshness
  • Shelf life
  • Efficacy of efficient microbial growth
  • Indicate the safety of the product
  • Examine pathogenic microorganisms

Frequently Asked Questions

Is Matís researching the health of drinking water?

Yes! Matís ohf's microbiology department investigates whether drinking water is healthy. The total bacterial count of E. coli and E.coli at 22 ° C is usually studied. It is also possible to obtain physical measurements of the water, such as pH and conductivity.

How long does it take to have the health of drinking water tested?

It takes 3 days to study the health of drinking water.

Contact: Hrólfur Sigurðsson

 

Do I need to take a sample of drinking water in a special sampling bottle?

Yes, it is necessary to take the sample in a sterile sampling tube. Such a bottle can be obtained from Örverudeild Matís ohf or buy two sterile urine test bottles at the nearest pharmacy.

Do you perform autoclaves testing for beauty salons and dentists?

Yes, it is possible to order special bacterial spores that we send to customers. The customer puts these spores in his autoclave and then sends them back to us. We confirm whether their autoclave has managed to kill the spores in question.
