SW-865 Small Head sterile Polyester Swab

Product Overview

The SW-865 is a sterile polyester swab with a knitted polyester fiber head that has undergone strict aseptic treatment to achieve complete sterility prior to package opening, designed for precision cleaning and surface disinfection tasks in medical, biotechnology, and laboratory environments where cross-contamination prevention is a regulatory requirement and the cleaning tool itself must not introduce microbial contamination to the treated surface. As a sterile polyester fiber swab, the SW-865 occupies a distinct functional position from the SW-982D sterile foam swab: the polyester fiber head provides a firmness and scrubbing capability that foam cannot match, making it the appropriate sterile swab choice for tasks requiring active residue removal through fiber abrasion — instrument surface scale cleaning, residue scrubbing from medical device contact zones, and precision component cleaning in regulated manufacturing — rather than purely liquid application and surface wiping that foam handles more gently.

The swab head measures 24mm in length, 13.5mm in width, and 3.6mm in thickness. The 3.6mm fiber depth provides meaningful liquid absorption capacity for a sterile polyester swab, allowing it to carry disinfectant solution and release it evenly across the contact surface during the wiping pass. The knitted polyester fiber construction is lint-free and generates low particle counts during use, maintaining compliance with cleanroom and sterile field cleanliness standards while providing more mechanical cleaning contact than soft foam alternatives.

Aseptic Treatment & Sterile Field Compatibility

The aseptic treatment applied to the SW-865 covers both the polyester head and the handle rod, ensuring complete sterility of the full swab assembly rather than only the contact tip. This full-swab sterile status is relevant in operating environments where the handle enters the sterile field alongside the head — such as in laminar flow workbenches, isolators, and restricted access barrier systems used in pharmaceutical compounding and aseptic fill operations — where a non-sterile handle surface would compromise sterile field integrity even if the swab head itself is sterile.

The polyester fiber demonstrates good chemical compatibility with standard medical disinfectants including IPA-based surface disinfectants, quaternary ammonium solutions, and hydrogen peroxide-based formulations used in pharmaceutical manufacturing cleanrooms and medical device production environments. The polypropylene handle measures 125mm in total length with 5.6mm width and 2.5mm thickness, providing stable single-handed operation in sterile glove conditions. Package contains 100 pieces in sterile-specification packaging.

Industry Applications & Use Scenarios

The SW-865 is used in medical device manufacturing, pharmaceutical cleanroom operations, biotechnology laboratory cleaning, clinical instrument servicing, and regulated sterile processing environments where swab sterility is a documented process requirement. Specific use scenarios include cleaning medical instrument contact surfaces between procedure cycles, removing scale and deposit buildup from laboratory utensil surfaces under sterile conditions, surface disinfection of medical device assembly fixtures in ISO 13485-regulated manufacturing operations, cleaning sterile workbench surfaces in aseptic pharmaceutical compounding environments, and precision cleaning of diagnostic instrument contact zones in clinical laboratory settings. The polyester fiber construction makes it the preferred sterile swab over foam alternatives specifically for tasks where the fiber's scrubbing ability is needed to dislodge dried deposits or residues that foam contact cannot mechanically remove.
