The TA Specialist will ensure accurate sample preparation, maintain laboratory organization and document all activities in compliance with applicable regulatory guidelines. This position plays a critical part in the biocompatibility and analytical testing pipeline for medical devices. The Test Article Preparation Specialist is responsible for preparing device samples and performing chemical extractions that feed directly into in vitro and in vivo testing protocols. Working closely with testing laboratories, the specialist must maintain precise timelines and meticulous documentation to support regulatory submissions. The role requires a strong foundation in chemistry or biological sciences, an eye for detail, and the ability to follow complex written protocols with consistency and accuracy. PRIMARY RESPONSIBILITIES FOR THE TEST ARTICLE PREPARATION SPECIALIST INCLUDE Sample Preparation Prepare samples by performing cutting, weighing, rinsing, mixing, extracting and sterilization procedures in accordance with established protocols. Ensure all samples meet dimensional, surface, and sterility requirements prior to submission for testing. Perform samples dilutions and aliquoting using clean-handling techniques to prevent cross-contamination. When applicable, ensure all samples meet sterility requirements prior to submission for testing. Ensure accurate sample identification throughout the preparation process. Extraction & Chemical Analysis Conduct solvent feasibility studies and perform extractions for chemical characterization and biocompatibility evaluations per ISO 10993-18. Perform non-volatile residue (NVR) analysis for exhaustive extractions to support chemical characterization studies. Documentation & Regulatory Compliance Following ALCOA principles, accurately document all sample preparation steps, observations and test results. Prepare and report test results summaries to scientists. Maintain accurate SDS documentation. Laboratory Maintenance & Operations Clean, maintain and calibrate basic laboratory equipment (incubators, ovens, balances, pH meters, rotary evaporators) to prevent contamination and ensure proper operation. Prepare chemical solutions. Prepare and maintain sterile glassware and consumables required for the sample preparation process. Organize and restock the prep lab to maintain an efficient, clean, and safe work environment. Train new staff in procedures, equipment operation and safe chemicals and samples handling. Study Coordination & Timeline Management Support laboratory analysts by ensuring samples are prepared and delivered according to project timelines. Proactively communicate any deviations, delays, or issues that may impact study schedules. Safety & Compliance: Follow laboratory safety procedures and protocols for proper samples storage, handling and disposal. Ensure appropriate Personal Protective Equipment (PPE) is always worn. Requirements: QUALIFICATIONS AND SKILLS FOR THE TEST ARTICLE PREPARATION SPECIALIST Bachelor of Science (B.S.) in Biology, Chemistry, Biomedical Engineering, or a closely related field. 1-5 years of hands-on experience in a laboratory setting, with preference for medical device testing or regulated laboratory environments.
