Solution viscosity of polymersin compliance with ASTM D 2857, ASTM D 871, ISO 1628, ASTM D 1243, ASTM D 789, ISO 307 & ASTM D 4603.

TheRHEOTEK Polymer Viscometer RPV-1provides a proven and precise method for determining:

• Inherent & intrinsic viscosity of polyethylene terephthalate, (PET),
• Relative viscosity or viscosity number of polyamides, (PA),
• K-value of poly vinyl chloride, (PVC).

Rheotest-RN-4.2:Rheolaser was developed for performing passive Micro-rheology analysis for soft material.The rheolaser isdedicated to formulators interseted in the end-use properties of their products, such as gelation, stress, recovery, shape stability, long term stability and many others.

The Rheolaser Master is the new spearhead o fthe microrheology range.Itis specifically designed for monitoring viscoelastic evolutions such as SOL-GEL transition (gelation), viscoelastic changes during ageing or recovery, on the very same sample.

HOPPLER-KF-3-2:Falling Ball Viscometer was developed by Mr. Fritz Hppler and mainly used for viscosity determination of transparent Newtonian liquids. It consist of main instrument (viscometer and support) with precision thermometer (-1 bis +21C) and 6 measuring balls with ball gage in case.

It is based on the measuring principle by Hoeppler.It enables simple but precise measurements of the dynamic viscosity of light transmissive Newtonian liquids.The Falling Ball Viscometer operates according toDIN 53015.

TCB-7 high quality viscometer bath, small footprint, stainless steel robust case. Seven viscometer positions arranged in two rows. TheTCB-7is supplied complete with leveling feet, viscometer hole covers and thermostatic controller.

A comprehensive range of calibratedprecision glass capillary kinematic viscometers for both manual and automated use. These instruments are used in laboratories across the world and enjoy a high reputation for quality of workmanship and accuracy of calibration.

PSL viscometers are constructed from low-expansion borosilicate glass and the precision bore tubing used for the capillary section is held to a close tolerance of 0.01mm.

PSL-RHEOTEK AUTO Kinematic Viscometerscanbe configured with a combination of one or twobath cells:

• Auto bath cell
• Sub-zero bath cell
• Multi bath cells
