Advanced Intrinsic Viscosity (IV) Measurement Instrument
TESTRON IVS series is a unique test instrument designed for fast and safe intrinsic viscosity (IV) measurement. It is designed according to ISO, ASTM, DIN, and GB standards. The system can directly calculate the Intrinsic Viscosity of (polyethylene terephthalate) PET preform, granules, flakes, and powder.
Standards Followed by the TESTON IVS Series
ASTM D 4603: Standard Test Method for Determining Inherent Viscosity Of Poly Ethylene Terephthalate (PET) By Glass Capillary Viscometer
ISO 3105: Glass capillary kinematic viscometer specifications and operating instructions
ISO 1628—5:1998: Thermoplastic polyester homopolymers and copolymers Polybutylene terephthalate (PBT)-polyester Polyethylene terephthalate (PET)-polyester resin
This test method is for the determination of the inherent viscosity of polyethylene terephthalate (PET) soluble at 0.50 % concentration in a 60/40 phenol/1,1,2,2-tetrachloroethane solution by means of a glass capillary viscometer.
Test summary for the PET Intrinsic viscosity measuring.
- Sample preparation: Prepare the solvent and sample by weighing on balance)
- PS: If the samples are preforms, place them under liquid nitrogen then crush it into powder.
- Mix the sample with solvent and then place it in the sample dissolver.
- Pour the dissolved sample into the viscometer and start measuring (Automatic/Manual)
- Wash the tubes after the test (Automatic).
Intrinsic Viscosity (IV) series key features:
- On-line automatic cleaning instead of manual cleaning.
- Avoid touching chemical reagents to ensure the safety of testing personnel.
- No need to disassemble the Ubbelohde viscometer to avoid man-made damage.
- It directly calculates Kinematic Viscosity, Dynamic Viscosity, Relative Viscosity, Viscosity Ratio, DP (degree of polymerization) Intrinsic Viscosity, Viscosity-average Molecular weight, etc.
- All viscosity design formulas in the system; testing personnel can use them conveniently.
- With data statistics function, can analyze variation trend of the samples. Provide the basic data for controlling the quality of your products.
- Can complete serial Trend-extrapolation way easily.
