JOHANNESBURG LABORATORY

There are 2 Servochem Laboratories - located on-site in Johannesburg and Durban, and both have been well equipped to handle the many relevant tests that our customers and suppliers benefit from on a daily basis. We have a full time team working in the laboratories, where we offer product testing, product training and product development. We are constantly working with our suppliers to identify product placement opportunities within the market, where we are able to often assist customers with improving quality and reducing cost.
