Determining the Residual Seal Force (RSF)
Determining the Residual Seal Force (RSF)
MECHANICAL TESTING OF MEDICAL VIALS
Parenteral products such as injectable medications and vaccines are commonly packaged in glass vials. These vials must maintain a robust seal between the glass vial and the elastomeric closure to prevent product contamination and leakage. Residual Seal Force (RSF) is an evaluation of the quality of this seal.
The glass vials subjected to RSF evaluation are used exclusively within the healthcare industry. A perfect example of the importance of RSF testing is the COVID-19 vaccine: some of the vaccines need to be stored at extremely cold temperatures in order to remain effective. Extremely cold temperatures can cause elastomeric materials to contract, which could cause the vial seals to leak. RSF testing can be performed at the full range of possible temperatures to assist manufacturers in evaluating raw materials and assembly processes. This verification is critical in ensuring that products can withstand travel and storage before being administered to the patient.
