PSL Rheotek Polymer Sample Preparation​
PSL-Rheotek - Polymer Sample Preparation
Weight to weight
Simply weighing 0.125 grammes of a polymer and adding solvent to the vial is not so simple. Working with very small portions of polymer sample requires excellent skills and constant attention to detail. Using the iSP-1 module from PSL-Rheotek takes the stress out of the process.
An innovative approach to the process involved in generating the polymer solution, provides the most user-friendly solution in the market place. The need for handling individual grains of polymer sample in order to achieve the target weight is removed, when using the iSP-1. The intelligent unit works by adjusting the quantity of solvent required in order to obtain the target concentration. The detailed precision work involved in generating the solution is moved from the hands of the operator to computer controlled fine mechanics.
How it works
The sample is added to the vial, which is located on the balance pan. Then the sample is weighed. The PSL Rheotek software will then calculate how much solvent is required for the solution to land on the target concentration. The next step is for the software to control the accurate dispensing of the solvent. This is dispensed from a syringe pump via a needle directly into the sample vial. At this point, the vial is still on the balance pan.
Night shift test work
Using the iSP-1, the laboratory achieves accurate concentrations every time. This technology ensures that samples are always accurately prepared in an operator independent fashion. Solution viscosity is therefore a realistic option for ongoing quality control, also during night shift hours in the process plant.

Description
Simple Operation
Operator selects one of the pre-programmed methods, types in the sample ID & presses the “Prepare Solution” button. The iSP-1 then takes over and asks the operator for the vial. The iSP-1 uses a series of audio prompts to instruct the operator how to prepare the sample. Safety checks ensure that the vial is placed on the balance. ISP-1 then asks for the sample. The operator adds sample until the iSP-1 prompts them to stop adding sample. Finally the iSP-1 calculates the correct amount of solvent and dispenses it into the vial.
Safety
Various safety checks throughout the process ensure the operators safety and prevent solvent being dispensed incorrectly.
