R&D and Process Development Applications for Implants

You are committed to improving mechanical and biocompatibility characteristics of implant materials for better patient experiences. We are committed to providing the products you need to ensure premarket approval. Consider the following applications: 

Measure Liquids, Pastes and Solids – Precisely, Accurately and With Full Regulatory Compliance

Coatings, 3D inks, plastics, metals - guaranteeing the specified density of raw materials is crucial for stability and safety of drug delivery systems. Deviations due to impurities or poor quality may have profound effects on the final product’s performance. 

Our solutions are tailored to the needs of density applications. Durable, high-performance balances and pycnometers, integrate with user management systems to generate traceable results, for precise and reproducible density calculation.

  • Check density of solids, liquids and pastes with one balance, even highly viscous or solid materials with densities in excess of 3 g/cm3
  • Increase measurement precision and process safety
  • Document results compliant to 21 CFR Part 11 & EU GMP Annex 11, USP Chapter 41

Maximum Recovery in Minimum Time

ISO 10993-1 requests a safety evaluation and risk assessment to exclude potential harmful effects of constituent materials, as for nanomaterials. Prior to evaluating reference values like conjugation or encapsulation efficiency, zeta potential and size distribution, successful purification and concentration of the suspension or dispersion is essential. However, typical separation methods like size-exclusion chromatography and dialysis require subsequent concentration steps and extensive manual handling that is time-consuming and costly.  

Sartorius Lab Ultrafiltration solutions move you one step ahead:

  • Perform purification and concentration steps simultaneously, reducing manual handling time
  • Highest recovery in the fastest possible time
  • Save consumable costs

Save Time and Improve Reproducibility

The biological risk of an implantable device is directly linked to its surface properties and the complexity of its constitutive components. Assessing the composition of materials and their ability to release extractables and leachables is standard in evaluating biocompatibility. FTIR, MS, ICP-MS or GC require robust, reliable sample preparation and streamlined workflows to ensure clean, reproducible, interference-free results. 

Sartorius provides user-friendly sample prep tools for Chemical Characterization per ISO 10993-18. Time-saving solutions for preparing samples for content and purity analysis produces robust and reliable sample processing procedures.

  • Fast, simple and economical 
  • Fully automated preparation of standards
  • 21 CFR Part 11 & EU GMP Annex 11, USP Chapter 41 compliant records
  • Filtration solutions with low retention volumes and maximal recoveries
  • Minimum leachables or extractables

Insight into Active Biological Processes in Real-Time

Cytotoxicity testing is a standard biocompatibility test to evaluate toxicity levels or irritancy potential of the drug delivery system or material. According to ISO 10993-5, the quantitative MTT Assay involves the incubation of cultured mammalian cells in contact with a device and/or extracts to determine biological response. 

Sartorius’ Incucyte® Live-Cell Analysis Systems are ideally suited to perform non-invasive monitoring under stable culture conditions and quantitative live-cell imaging and analysis in real-time:

  • Visualize and quantify cell behavior around the clock 
  • Time-lapsed, kinetic measurements in long-term
