MUHWA 5-Roll Autoclave Tape — Steam Sterilization Indicator Tape for Reliable Process Confirmation
MUHWA 5-roll autoclave tape provides simple, visual confirmation that wrapped instruments, glassware, media, and supplies have been exposed to steam sterilization conditions. Each roll contains 50 meters of tape (12.5mm width) with printed diagonal chemical indicator stripes that change from white/beige to dark brown/black upon exposure to saturated steam at standard autoclave temperatures (121C or 134C). The clear, permanent color change provides an immediate visual check at a glance. The 5-roll bulk pack (250 total meters) provides economical supply for hospital CSSD, dental and veterinary clinics, research laboratories, and pharmaceutical facilities.
Key Features
- Clear Chemical Indicator Stripes — Diagonal indicator lines provide unambiguous, high-contrast color change after steam exposure. Change is permanent and will not fade or reverse.
- 5 Rolls x 50 Meters — 250 total meters. Ample supply reduces reorder frequency and per-meter cost for high-throughput facilities.
- 12.5mm (1/2 inch) Width — Standard width compatible with bench-top tape dispensers for efficient one-handed dispensing during pack wrapping.
- Strong, Clean-Removing Adhesive — Adheres firmly to sterilization wrap, paper, plastic, and metal throughout the autoclave cycle. Removes cleanly without residue.
- Write-On Surface — Matte tape surface accepts permanent marker for writing date, contents, load number, and operator initials before sterilization.
- Temperature Responsive — Color change activates at 121C (gravity cycle) or 134C (pre-vacuum cycle). For steam autoclaves only — not suitable for dry heat or chemical sterilization.

Important Usage Notes
- Indicator tape confirms exposure, NOT sterility — The color change verifies the item has been through a steam autoclave cycle. Always use biological indicators (spore tests) and chemical integrators for sterility validation per facility protocol.
- Not for dry heat or chemical sterilization — The indicator chemistry is specific to steam. It will NOT change color in dry-heat, ETO, or hydrogen peroxide sterilizers.
- Store cool and dry — Exposure to high humidity, direct sunlight, or temperatures above 40C before use may cause premature indicator activation.
Applications
- Hospital CSSD and Instrument Processing — Seal wrapped surgical trays, peel pouches, and rigid containers. Visual confirmation for OR staff.
- Dental and Veterinary Clinics — Secure and identify sterilized instrument cassettes and procedure packs for infection control compliance.
- Research Laboratories — Seal autoclaved glassware, media bottles, pipette tip boxes, and biohazard waste bags.
- Pharmaceutical Manufacturing — Process indicator for steam-sterilized components, tubing assemblies, and cleanroom supplies in GMP environments.
- Tattoo and Piercing Studios — Sterilization confirmation for autoclaved instruments per health department regulations.
Frequently Asked Questions
Q: What temperature does the tape change color?
A: The indicator stripes activate upon exposure to saturated steam at 121C (standard gravity cycle) or 134C (pre-vacuum cycle). Both heat AND moisture are required — the steam must penetrate for activation.
Q: Can I write on the tape before autoclaving?
A: Yes. Use a permanent marker to write date, contents, and initials on the tape before applying. The ink remains legible after autoclaving.
Q: How should I store unused tape?
A: Store in a cool (below 25C), dry environment away from steam pipes, direct sunlight, and autoclave heat. Keep in original packaging until use. Improper storage can cause premature indicator activation.
Q: Is there an expiration date?
A: When stored properly, shelf life is approximately 2-3 years from manufacture date. Check packaging for expiration. Tape with prematurely darkened stripes should not be used.
