How do serum bottles safeguard the stability of biological reagents?
In biomedical laboratories, serum vials are small but bear an important mission.As a storage container for culture media, serum and various reagents, its quality directly affects the reliability and reproducibility of experimental results. A high quality serum vial needs to fulfill a number of stringent technical requirements in order to ensure the safe storage of precious samples.

A high quality serum vial needs to fulfill a number of stringent technical requirements in order to ensure the safe storage of precious samples.
Transparency and accurate scale are the basic requirements for serum vials. High-quality serum vials have a light transmission rate of more than 90%, and the square design of the vials with laser-engraved scales can control the error within 2%. Such a design allows laboratory personnel to clearly observe the liquid state, accurately grasp the remaining amount of reagents, providing a reliable basis for experimental operations.
The sealing performance is directly related to the safety of reagent storage. High-quality serum vials are made of medical-grade PP or HDPE caps, which have passed strict negative pressure tests to ensure complete sealing. The specially designed screw cap has a built-in sealing gasket that prevents leakage even when stored upside down for long periods of time. This reliable sealing effectively prevents the intrusion of external contaminants and avoids the loss of reagents through volatilization.
In terms of material selection, PETG is becoming the ideal choice for high-end laboratories. Compared to traditional PET materials, PETG has superior performance: its light transmission is close to that of glass, it remains stable in liquid nitrogen environments at -196°C, and its gas barrier performance is enhanced by more than 30%. Industry Application Scenarios
✓ Vaccine production: high-density culture of vero cells and MRC-5 cells. ✓ Monoclonal antibody preparation: large-scale expansion of CHO cells
✓ Gene therapy: stem cell vector production Currently, many vaccine companies around the world have adopted cell factories as an alternative to the transfer vial process.Its core value lies in the fact that it carries more capacity in less space and guarantees higher compliance with lower contamination rates - the ultimate demand for scale-up of biopharmaceutical production.After all, these seemingly ordinary containers are the first line of defense to guard the accuracy of experimental data.
