A Guide to the Use of Osmometers​
A Guide to the Use of Osmometers​

An osmometer is a specialized instrument designed to measure the osmotic pressure of solutions, a key parameter in fields such as biochemistry, medicine, food science, and environmental monitoring. By determining osmotic pressure, it helps assess the concentration of dissolved solutes in a solution, which is critical for applications like cell culture maintenance, clinical diagnosis (e.g., measuring urine or blood osmolarity), and quality control of beverages or pharmaceuticals. This guide provides a step-by-step overview of how to use an osmometer correctly, safely, and efficiently.​

What are the commonly used detection methods in automatic enzyme-linked immunosorbent assay (ELISA) reader

Automatic enzyme-linked immunosorbent assay (ELISA) is an instrument used for detecting biomolecules, mainly for determining the content, purity, and activity of biomolecules such as proteins and nucleic acids. It has the advantages of high sensitivity, fast detection speed, and easy operation, and has become an important tool for life science research and clinical diagnosis.

Understand the measurement principle of the freezing point meter

The PSI CRYETTE freezing point meter uses supercooling and thermocouples to accurately measure the freezing point of a solution. The supercooling phenomenon refers to the phenomenon where the temperature of a solution is below the freezing point without freezing.

  • What are the reasons that affect the temperature uniformity of a constant temperature and humidity chamber?
    The constant temperature and humidity chamber has dual functions of cooling and heating, and belongs to experimental equipment. When conducting environmental tests, if the temperature uniformity exceeds the allowable deviation range, the data obtained from the test is unreliable and cannot be used as material or product environmental test tolerance performance.
  • Principle of 4250 Freezing Point Penetrometer Determination Method
    -Milk belongs to colloidal solutions, and its freezing point has relative stability (the normal freezing point of milk is about -0.525 ℃ to -0.565 ℃). When water is added to milk, its solid content decreases and the freezing point rises towards 0 ℃ (i.e., the freezing point rises). -By utilizing this characteristic and adopting industry standard freezing point measurement methods (such as the application of Raoult's law), the freezing point of the sample is determined using a 1.4250 device, and the amount of water added is calculated using a standard formula to achieve accurate detection.
  • Can microbial detection bottles detect anaerobic bacteria?
    Cannot detect dead bacteria.
