Chitosan, also known as deacetylated chitin,The excellent biological properties and compatibility, blood compatibility, safety, and microbial degradation of this natural polymer have attracted widespread attention from various industries, and significant progress has been made in the application research of many fields such as medicine, food, chemical industry, cosmetics, water treatment, metal extraction and recovery, biology and biomedical engineering.
Chitosan is odorless, tasteless, and non-toxic, with pure chitosan having a slight pearl luster. The relative molecular weight of chitin in living organisms is 1 × 106-2×106After extraction, the relative molecular weight of chitin is about 3 × 105-7×105The relative molecular weight of chitosan produced from chitin is lower, about 2 × 105-5×105The relative molecular weight of chitin and chitosan during the manufacturing process is generally expressed by the numerical value of viscosity.
Viscosity is an important indicator for measuring chitosan materials. Measuring the intrinsic viscosity of chitosan dilute solution can determine the relative molecular weight and polymerization degree of chitosan material, as well as understand the existence and branching degree of its molecular chains in the solution.
IVS800 Fully Automatic Viscosity Measurement System
The Zhongwang fully automatic viscosity measurement system IVS800 achieves a fully automated measurement process based on the Ubbelohde viscosity method as the core measurement method. Significantly improved the accuracy of counting, temperature control range, and temperature field uniformity during the testing process.
test process
01
Weighing samples
useOne ten thousandth scaleWeigh chitosan and place it in a dissolution bottle. Use a DP25 automatic liquid dispenser (with a transfer accuracy of ≤ 0.1%) to transfer a quantitative amount of 0.2% sodium chloride solvent into the dissolution bottle;
02
Dissolve sample
Place the dissolution bottle into the P12 Zhongwang Polymer Dissolver and dissolve the sample using magnetic stirring at the specified temperature and time;
03
Viscosity measurement
Place the chitosan sample dissolution bottle of the device into the IVS800 sample tray with the pre-set water tank temperature, activate the testing function, and automatically obtain the test results;
04
measurement results
The IVS800 fully automatic viscosity measurement system is connected to the computer end, which can automatically obtain test results and store them for diversified viscosity data analysis;
05
Clean the viscosity tube
The viscosity tube is fixed in the constant temperature water bath of IVS800 viscosity analyzer, without the need for disassembly and removal, and can be automatically cleaned, discharged, and dried.
