Osmotic pressure tester

Osmotic pressure testerAccording to the Raoult freezing point theory, based on the proportional relationship between the decrease in solution freezing point and the molar concentration of the solution, high-sensitivity temperature sensors are used to measure the freezing point of different solutions, and then the osmotic pressure molar concentration of the measured solution is obtained. Widely used in the testing and research of osmotic pressure molar concentration in pharmaceutical, pharmaceutical analysis, biology, food and medical fields.

Main features:
1. Humanized design, 7-inch color touch screen, Chinese interface, easy and fast operation:
2.High precision sensor with high measurement accuracy and good reproducibility.

3. Single point or multi-point (31 point) linear calibration can be performed to ensure the accuracy of the instrument's detection in various range intervals during stability.
4.The sample name can be entered by oneself without the need to connect to a keyboard.
5.The temperature probe adopts a screw linear guide motor design, and the entire testing process can be completed by operating it on the touch screen.

6. Adopting a dual refrigeration system, the pre cooling time is short, the detection speed is fast, and it is convenient for continuous detection.
7. With a small sample size, it can meet the needs of different fields.
8. It can simultaneously display the osmotic pressure molar concentration value, freezing point value, and molar concentration ratio of the sample.
9. The cooling system adopts a design without heat transfer fluid, which eliminates frequent maintenance.
10Equipped with electronic signature and user grading management function, it meets FDA 21 CFR PART 11 storage data query by time and can store 5 years of testing data (the instrument itself has audit function)
