OUR STORY
Helping process industry customers certify PET, PA, PULP, MCC, PVC & HA
Process plants across the world trust their PSL Rheotek viscometer systems for daily testing of product stream. Using an automated glass capillary viscometer system, they determine intrinsic viscosity, K-value, degree of polymerisation, – all in full compliance with international test methods.
Test results form part of legal contracts for bulk trading of commodities deep in the cogs of the manufacturing process.
PSL Rheotek automated viscometer systems first appeared back in the late 1990’s in response to industry requirements for automation. Then and now, Poulten Selfe & Lee Limited, was already a world player in the field of capillary viscometry. With a manufacturing and calibration operation covering the standard viscometer tubes as per specifications of ASTM, DIN, ISO and other standards organisations, the move into automation was organic.
PSL was originally established in 1850 and supplied a wide range of laboratory equipment. Scientific glassblowing was always at the heart of the manufacturing process. In more recent history, the glassblowing expertise and experience has been exclusively focused on capillary viscometers. We make beautiful viscometers with excellent flow properties.
Currently, the PSL Rheotek range of automated viscometer systems are on Generation 3. It is our mission to assist manufacturers to employ scientific method in their operation.
A special area of interest for us is to work with manufacturers in emerging markets. In addition to a very comprehensive base of installations in North America and Western Europe, we are also active in Vietnam, Pakistan, Indonesia, South Africa and Angola.

OUR MISSION
Making Polymer Solution Viscosity easier
Recyclers, compounders, petrochemical industries, pulp mills and pharmaceutical manufacturers all need to run continuous viscosity testing on product stream. The certificate of Analysis is a key document for process control. The certificate of analysis is also a key document for product sale. At PSL Rheotek we focus on designing the right configuration of instrumentation for each client. Our mission is to help manufacturers obtain the right data in the easiest and most convenient way using glass capillary viscosity measurements.
We see ourselves as a small cog in the big machine of process industry. Our technology assists process industry with optimizing their process. This helps them to limit their waste and send the right product into the next stage of manufacturing.
