Fisherbrand Microscope Cover Slips 22 mm Plastic Unbreakable Case of 1000 Cover Slips

Fisherbrand Unbreakable Plastic Microscope Cover Slips, 22 x 22 mm (12-547) – Case of 1,000

The Fisherbrand Unbreakable Cover Slips (12-547) are durable, high-clarity optical accessories engineered as a safe, cost-effective alternative to traditional glass coverslips in routine educational, clinical, and industrial microscopy workflows. Precision-pressed from high-grade polyvinyl chloride (PVC), these plastic cover slips eliminate the risk of glass breakage, sharp injuries, and optical distortion during rapid slide preparation. Featuring a flexible, non-curling physical profile, they maintain a consistently flat surface across standard 25 x 75 mm microscope slides. Supplied as a bulk case of 1,000 cover slips packaged in 10 convenient dispenser boxes of 100 sheets each, this consumable line is ideal for high-throughput teaching laboratories, field diagnostics, and routine biological specimen mounting.

Technical Performance & Physical Integrity

• Unbreakable PVC Construction: Formulated from high-purity pressed vinyl chloride resin that withstands physical impact, dropping, and pressure without shattering. This provides a safe, shatterproof environment for student labs and mobile testing units.
• Flat, Non-Curling Optical Plane: Specially treated to resist curling and warping upon contact with aqueous mounting media or environmental humidity changes. This preserves a flat focal plane for consistent light transmission under standard brightfield objectives.
• Controlled Thickness Range (0.17 to 0.25 mm): Manufactured to a standard optical gauge profile corresponding roughly to Number 1.5 to Number 2 glass coverslip thickness. This ensures optimal refractive performance for low- to medium-magnification microscopy.
• Interleaved Box Packaging: Supplied in compact 100-count dispenser boxes designed to prevent static cling and scratch formation during individual sheet extraction.
