EST. 1978

Labserve was established in 1978 and is situated in Nelspruit, Mpumalanga, South Africa. It is currently the only ISO 17025:2017 accredited laboratory in the Mbombela area (please visit for our schedule of accreditation or more info).


We have over 40 years experience in supplying analytical services to the greater Ehlanzeni district as well to customers both countrywide and as far afield as Mozambique, Swaziland, Madagascar, Zambia, Mauritius and the DRC.


Labserve has been instrumental in numerous municipalities receiving and maintaining both Blue and Green Drop status (now renamed IRIS).


We are proud to have been appointed as an officially recognised laboratory by DAFF (Department of Agriculture, Forestry and Fisheries) from 1 March 2018 to perform MRL (maximum residue limits) analysis on fruits and vegetables destined for export.

As there is little capability locally in the area of pesticide and organic analyses, we have purchased a gas chromatograph with a mass spectrometer (GC-MS) and a high-performance liquid chromatograph linked to a triple quadrupole mass spectrometer (LC-MS), and we have extended our SANAS scope of accreditation (MRL pesticide testing on fruit and vegetables) in 2017. We have recently opened a Labserve Mycro © division in the Western Cape. This satellite laboratory focuses on specialised agricultural analyses. This new addition to the Labserve family will deliver the same reliable results and quality of service that are synonymous with our brand.

Labserve currently employs twenty people in our lab. All of our staff are all highly qualified and trained in their fields of expertise.

Labserve’s Technical Manager and owner since 1999, Mr. Larne Auerswald, is responsible for managing laboratory affairs and for developing new areas of expansion. Larne has a BSc. Agric (Hons) from the University of Natal, Pietermaritzburg.

The head of organics at Labserve is Willem Immelman who completed a BSc. in chemistry and applied mathematics in 2012. Willem spends most of his time developing GC-MS and LC-MSMS methods among others and has developed the largest accredited pesticide residue analysis list in the country, developing and validating over 60 methods. Willem is also responsible for establishing and coding a designer laboratory integrated system (LIMS) as well as managing most of the laboratory’s IT needs. He is fully ISO trained.
