An osmometer is an efficient tool for determining the number of particles in blood, urine, or other fluids. The osmotic pressure will increase during dehydration, whereas when the water pressure is high, the osmotic pressure will decrease. There are three types of osmotic pressure: urine, plasma and stool. Urine osmotic pressure is the detection of renal function, blood osmotic pressure is a sign of the recruitment of blood diseases; stool test is the cause of diarrhea. The osmometer can also be used in the test environment and is an instrument for accurately measuring the osmotic pressure of liquids.
The advantages of the dew point method compared with the freezing point method :
1. No need to change the image shape of matter
2. It can handle semi-solid samples used in clinical and industrial chemistry laboratories that cannot be processed by the freezing point method.
3. The sample size is small, 10 microliters, and 2 microliters can be achieved by special techniques.
4. Accurate results can be easily obtained for samples containing suspended particles or thicker samples.
5. The osmotic pressure of plant and animal tissue sections can be directly measured. Such as the leaves of plants, the brain and kidney slices of animals.

An osmometer is an efficient tool for determining the number of particles in blood, urine, or other fluids. There are three types of osmotic pressure: urine, plasma and stool. Urine osmotic pressure is used to diagnose renal function, and blood osmotic pressure is a marker for the recruitment of blood diseases; stool testing helps determine the cause of diarrhea. In particular, the dew point osmotic pressure can directly measure the osmotic pressure of whole blood, making the measurement more convenient and faster.
Cell culture
Experience has shown that consciously measuring the osmotic pressure of the medium can effectively increase cell yield. Because the composition of the medium purchased each time varies greatly, it must be tested before use. Measuring the osmotic pressure of the medium can significantly increase tissue culture. Moreover, maintaining normal osmotic pressure can maintain the activity of the enzyme and prevent the distortion of the membrane.
Eye medicine products
By maintaining critical osmotic pressure parameters, it is possible to prevent morphological changes in the vitreous and infiltration into the eye solution.
QC
Pharmaceutical, hospital and nutritionists can use osmometers to measure treatment consistency and minimize trauma.
Voltage clamp research: (including patch clamp, oocyte voltage clamp and brain slice voltage clamp)
In the normal physiological state, the extracellular fluid environment in which the cells are located is very similar to the osmotic pressure of the intracellular fluid (about 300 mOsm). Voltage clamp studies require the separation of tissue cells into individual cells (eg, single cardiomyocytes, single neurons, and smooth muscle cells, etc.).
