Implants - Final Release Testing

Every prosthesis, surgical mesh, scaffold or breast implant must be confirmed to meet safety, efficacy and quality standards such as ISO 11607. 

Check density, moisture and dose accuracy as well as biocompatibility and bioburden. Prevent device defects and ensure finished products are stable and safe for use. Sartorius solutions support final release testing to demonstrate compliance with regulatory guidelines.

Final Release Testing Applications for Drug Delivery Systems

With the following applications, we are committed to providing you the products you need to validate your devices are safe for the patient and to guarantee the efficiency of the active ingredients:

Check Smallest Quantities

Extended wear, delivery of drugs, biocompatibility or corrosion resistance - coatings on drug delivery systems provide numerous benefits. To fulfill their function reliably, coatings, protection layers and foils must be picked up uniformly. 

Weighing by difference solutions from Sartorius are your best fit to verify that coating systems have applied the exact amount of medical grade polymer or API to an implantable device, such as a DES (Drug Eluting Stent). For reliable, reproducible and straightforward weighing workflows:

  • Highest precision for smallest quantities, protected against drafts and electrostatic charges
  • Sample holders accommodate differently shaped products
  • Full data traceability and integrity
  • Compliant to 21 CFR part 11 and EU Annex 11

Determine Moisture Contents Within Minutes

Drug delivery system packaging must provide a secure barrier to preserve the product until use. To avoid microbial contamination, friction or oxidation, the influence of moisture on packaging material like nylon, plastic, paper or cardboard has to be tested. It is mandatory to capture even the smallest deviations in moisture for assuring the appearance and functionality of the final product.

Sartorius offers robust and reliable solutions, so you accurately detect and document moisture contents quickly and easily within your routine applications: 

  • Compliant to ASTM Standard D6980, ISO 868-7 Annex E
  • Measure minimum moisture content down to 0.005 %
  • Process up to 4 samples simultaneously
  • Achieve highest precision, even for very dry samples
  • Comply with EN 868 for sterile barrier systems

Reliable Microbial Enumeration

Finished products must be free from microbial contamination to ensure consistent, reliable product quality and safety as per ISO 11737-1. Any undetected presence of microorganisms may cause unnecessary delays or product recalls. Prior to final sterilization and packaging, bioburden testing is carried out to determine the population of viable microorganisms on or in the product. Post sterilization, it can demonstrate the integrity of the sterilization process and sterility assurance during shelf life.

Our membrane filtration solutions for standard microbial enumeration protocols per USP <61> facilitate an efficient, accurate detection of potentially pathogenic or spoilage microorganisms:

  • Save time with ready-to-use sterile filtration devices
  • Minimize the risk of secondary contamination and false positives
  • Touch-free membrane transfer
