About us

Peter Johnson Laboratories is an ISO 17025 SANAS accredited, independent, boutique laboratory based in Montague Gardens, Cape Town, South Africa. That produces reliable and accurate chemical testing results, promised turnaround times and high customer satisfaction levels.  It is safe to say we are a women-owned-and-managed entity, are all “proudly South African” and 100% self-funded.

Our history

PJL became the “offspring” of J Muller Laboratories (Pty) Ltd in 2016. J Mullers was a well-established laboratory that was founded in 1925. Sometime around 1980 Peter Johnson purchased the laboratory from Dudley Harris. At the time the lab was situated in Beach Road, Woodstock and soon thereafter, moved premises to Marine Drive, Paarden Eiland, where they remained until December 2015, when the business folded.

In 2016 Peter’s daughter, Genevieve Michel, purchased the assets as a close corporation and set up a new laboratory in Montague Gardens so that Peter, aka the Chemist, could continue his work and jobs could be sustained for the long serving employees, who had become family over the years.

After Peter Johnson’s unexpected passing a year later, Annalize Labuschagne joined the business in October 2017 as Operations / Laboratory Manager. Annalize is a qualified Analytical Chemist and Microbiologist with over 20 years’ experience working in independent SANAS accredited laboratories, including working under Peter at J Mullers.

We are a diverse and close knit team of 12, many of whom have worked in the business (some over 30 years) and have been well schooled in the art of working in a laboratory by the Chemist.
