The PSI osmotic pressure specialized sample tube is a consumable used in conjunction with the PSI osmotic pressure instrument, mainly for calibrating and verifying osmotic pressure instruments based on the principle of freezing point descent, ensuring accurate, reliable, and traceable measurement results.

-Specification parameters: Common specifications include 30 μ l and 0.2ml. For example, the 2038 sample tube has a capacity of 30 μ l and is suitable for 2430/6003 instruments, with 500 tubes per pack.

-Material characteristics: It is usually made of polypropylene (PP) material, which does not release or adsorb substances that may affect osmotic pressure into the sample. It complies with ISO 13485/ISO 9001 standards and partially supports pharmacopoeial requirements such as USP<785>and EP2.2.35.

-Product features: The sample tube can be reused and easily cleaned, which not only saves costs but also reduces the tedious operation of sample tube replacement. At the same time, some sample tubes are equipped with transparent sample observation windows for easy observation of sample status, and the samples have independent spaces with sample protection plates to reduce contamination.

-Scope of application: Widely used in clinical testing, such as serum, urine, cerebrospinal fluid osmotic pressure measurement; It is also used for pharmaceutical quality inspection, such as osmotic pressure control for injection solutions, biological products, etc.
