What We Do

Established in 2002, Lactolab has developed into a leading analytical laboratory serving the South African dairy and dairy-related industries. Lactolab is located in the Dairy Building on the ARC campus in Irene and our main focus is the analysis of raw milk and dairy products for composition, hygienic quality and various other quality parameters. Many of our tests are SANAS accredited. We pride ourselves in providing our clients with a standard turnaround time of 24 hours after samples are received for all automated tests.

The instruments and technology we use are cutting-edge and we are committed to continually staying abreast of the latest developments. All instruments are internationally approved and meet or exceed IDF (International Dairy Federation) criteria. Furthermore, the accuracy of results from the instruments is locally and internationally benchmarked. Key personnel receive full technical training on these instruments. Chemical, physical and microbiological analyses are carried out using IDF/ISO standards or other internationally recognized testing methods.

Our clients range from major dairy companies to smaller operations as well as milk producers nationwide who require testing of their milk, dairy and dairy-related products. Lactolab strives to provide Rapid, Reliable Results and a one-stop service for all your dairy analytical needs – confidentiality guaranteed. In so doing, we contribute to our customers delivering quality milk and dairy products to consumers in South Africa and other African countries. Lactolab encourages long-term agreements and our tariff structure is negotiable depending on work volume and duration of contract/commitment.

In July 2016, LactoLab officially became part of the Mérieux NutriSciences network of over 80 accredited laboratories across 21 countries around the world. As part of Institut Mérieux, Mérieux NutriSciences is dedicated to protecting consumers’ health throughout the world, by delivering a wide range of testing and consulting services to the food & nutrition, agrochemicals, pharma and cosmetics industries.

Following this, in October 2016 we made the final step in the integration of Lactolab into the Mérieux NutriSciences family by moving all the former Lactolab staff, equipment and services to a brand new Raw Milk Laboratory in Midrand.

Lactolab (Pty) Ltd is now officially trading as Mérieux NutriSciences and can be located at Constantia Square Office Park, Stellenryk, 536 16th Rd, Midrand, Johannesburg, 1685. See map below.
