105 mm Sterile Disposable Forceps — Polystyrene, Translucent Blue, 100/Pack (222-1121-B1I)
These 105 mm single-use forceps are molded from virgin polystyrene (PS) and individually sealed in sterile peel-pouches, making them ready for immediate aseptic use without autoclave preparation. Supplied 100 per pack under part number 222-1121-B1I, they are engineered for histology, microbiology, clinical specimen handling, and biopsy transfer workflows where a disposable sterile instrument is required. The translucent blue color provides high visual contrast against stained tissues and agar surfaces, reducing instrument-tissue confusion in high-throughput processing environments.

Applications
- Histology & Pathology: Tissue handling and biopsy transfer to cassettes; disposable design eliminates cross-contamination between cases
- Microbiology: Membrane filter transfer and colony picking using individually packed sterile instruments for aseptic technique
- Clinical Specimen Handling: Specimen transfer and swab manipulation; single-use format prevents carryover between patient samples
- Molecular Biology: Gel excision and membrane manipulation during destaining procedures
- Forensics: Evidence handling and trace material transfer; the individual sterile pack supports chain-of-custody documentation
- Blood Banking: Filter handling and component separation; non-magnetic materials are safe in blood banking environments
- Veterinary & Field Labs: Field specimen collection and tissue manipulation where lightweight disposables reduce instrument load versus metal forceps

Quality & Procurement
Made in USA, these Caplugs® Evergreen forceps are molded from virgin, BPA-free, phthalate-free polystyrene and individually sealed in sterile peel-pouches to support single-use instrument documentation requirements in accredited clinical and research laboratories. The individually packed format eliminates autoclave cycles, instrument tracking overhead, and cross-contamination risk associated with reusable metal forceps in high-volume specimen processing environments. LabSupplies.com is an authorized Caplugs® Evergreen dealer shipping from USA inventory, with tiered pricing available for institutional, hospital, and grant-funded procurement teams.
Frequently Asked Questions
Are these forceps sterile right out of the box?
Yes — each forceps is individually sealed in a sterile peel-pouch and is ready for immediate aseptic use without any additional sterilization step.
Can these forceps be re-sterilized or autoclaved for reuse?
No. These are single-use instruments made from polystyrene, which is not autoclavable. Attempting to re-sterilize or reuse them could compromise sterility assurance and instrument integrity.
Why are the forceps translucent blue instead of clear or natural?
The translucent blue color provides high visual contrast against stained tissues and agar surfaces, helping technicians distinguish the instrument from specimens during high-throughput histology and microbiology work.
Is polystyrene suitable for procedures involving alcohols or fixatives?
Polystyrene tolerates brief contact with short-chain alcohols below 70%, but it is not resistant to acetone, xylene, chloroform, or other aromatic and chlorinated solvents commonly used in fixation and clearing protocols. For procedures requiring prolonged solvent exposure, consult your laboratory's chemical compatibility guidelines before use.
