STY-2AS Solution Osmolometer Molarity Freezing Point Tester
Overview:
The freezing point osmolometer STY-2AS, independently developed and produced by our company, is based on the Raoul freezing point theory and the proportional relationship between the freezing point drop value of solution and the molal concentration of solution. It adopts highly sensitive temperature sensing element to measure the freezing point of different solutions, and then gets the molal concentration of the measured solution. This theory has been widely used in the measurement and research of osmolality in paharmaceutical, drug analysis, biology, food medicine and other fields.
Features:
1. Humanized design, 7-inch color touch screen, Chinese interface, simple and fast operation:
2. With electronic signature and user classification management functions, to meet FDA 21 CFR PART 11 storage data by time query, can store 5 years of test data (the instrument itself has audit function)
3. Single point or multi-point (31 points) linear calibration can be carried out to ensure that the instrument has the detection accuracy of each range interval in stability.
4. The temperature probe adopts the lead screw linear guide motor design, which can complete the entire test process only by operating on the touch screen.
5. High precision sensor, high measurement accuracy, good reproducibility.
6. Double refrigeration system, short pre-cooling time, fast detection speed, easy to continuous detection.
7. The sample quantity is small, which can meet the needs of different fields.
8. It can display the osmotic pressure molar concentration value, freezing point value and molar concentration ratio of the tested product at the same time.
9. The cooling system is designed without heat conduction fluid, eliminating frequent maintenance.
10, sample name input, no need to access the keyboard.
