With respect to analytical testing GSTL have evolved close professional liaisons with a small number of Analytical Laboratories located in close proximity to our testing facilities.

This close liaison has allowed preferential rates to be established which in turn have been passed on to our Clients.

All the Analytical Laboratories are UKAS Accredited and are visited by ourselves on a regular basis to ensure that good communication is maintained.
