In the research and development fields of polymers, polymeric materials, and pharmaceutical raw and auxiliary materials, viscosity is one of the key indicators for measuring product quality. The accuracy of viscosity measurement data has a decisive impact on product quality control and final performance. Therefore, selecting a high-precision, multi-functional viscometer that complies with industry standards is crucial for improving experimental efficiency and ensuring data reliability.
Zhongwang Technology has launched the IVS400 full-automatic viscosity complete solution, specifically designed for viscosity measurement of materials such as polymers and polymeric materials. This solution greatly simplifies the measurement process of the traditional manual Ubbelohde viscometry method, including steps such as sample transfer, measurement, calculation, and cleaning. It not only significantly improves experimental efficiency but also effectively reduces direct contact between experimental personnel and chemical reagents, thereby enhancing the safety of experiments. Meanwhile, the IVS400 full-automatic viscometer fully complies with international and domestic testing standards such as ISO, GB, HG, DIN, and ASTM, ensuring the accuracy and reliability of measurement results.
Zhongwang Technology's IVS400 full-automatic viscosity solution, with its characteristics of high precision, multi-functionality, and compliance with industry standards, provides strong support for research and development in fields such as polymers, polymeric materials, and pharmaceutical raw and auxiliary materials.
Overall Viscosity Solution
No need to remove the viscometer; waste liquid can be directly pumped out, and cleaning solution can be added for cleaning;
Equipped with an automatic liquid adding module, which automatically adds liquid, cleans, drains, and dries after testing;
No matter how many measurement units are selected, only one set of waste liquid collection device is needed to complete waste liquid collection;
Greatly reduces the chance of experimental personnel coming into contact with toxic chemical reagents, ensuring the safety of experimental operators;
Can be connected to QDS/LIMS system, and experimental data can be automatically uploaded to realize a smart laboratory;
High-precision motor-controlled mechanical structure, with pipetting accuracy ≤0.1%;
Built-in constant temperature module to prevent samples from crystallizing when cold;
The liquid preparation function does not require manual calculation, and the pipetting volume is automatically matched with the balance; batch pipetting is completed automatically, freeing up manpower;
Operators only need to operate the touch screen of the machine to easily complete pipetting/liquid preparation, instead of facing dangerous reagents with ear wash balls and pipettes.
P Series Polymer Dissolver
Can hold 50ml, 70ml sample bottles, conical flasks and other vessels;
The constant temperature block is processed with an integral metal block to ensure uniform temperature in each hole;
Magnetic stirring, with adjustable speed, temperature and timing settings;
Widely used for stirring solvents with different viscosities.
