Heathrow Scientific 120722 Replacement Blades for Box Top Parafilm Dispenser are stainless steel replacement blades designed for Parafilm M box top dispensers.
Heathrow Scientific 120722 Replacement Blades are genuine stainless steel safety blades designed as direct replacements for the Box Top Parafilm® M Dispenser. Each pack contains 3 blades (23mm), maintaining the clean, fingertip-safe sliding cut that the Box Top Dispenser is built around. When a blade dulls and Parafilm® starts tearing instead of cutting cleanly, 120722 restores full cutting performance without replacing the dispenser body.
Features & Benefits
- Genuine Heathrow Scientific Replacement: Exact-specification 23mm stainless steel blades engineered for the Box Top Parafilm® Dispenser — guaranteed fit with no modifications required.
- Stainless Steel Construction: Corrosion-resistant material maintains a sharp, clean cutting edge through repeated use, delivering consistent Parafilm® cuts every time.
- Fingertip-Safe Design: Blades operate within the dispenser's integrated safety slider — no exposed cutting edge, eliminating the accidental cuts that come with scissors or standard utility blades.
- Pack of 3: Three blades per pack provides extended service life, keeping your dispenser operational across multiple blade changes before reordering.
- Extends Dispenser Life: Replacing only the blade — not the entire dispenser body — is a cost-effective way to maintain consistent Parafilm® cutting performance at a fraction of the cost of a new unit.

Laboratory Applications
Replacement blades are essential consumables in any lab that regularly seals flasks, tubes, petri dishes, or glassware with Parafilm® M. High-throughput molecular biology, microbiology, and cell culture labs where Parafilm® is used daily will burn through blades faster and benefit most from keeping 120722 in stock. Clinical labs, pharmaceutical QC benches, and food science applications that seal containers for storage or incubation are also common users. Having spare blades on hand eliminates workflow interruption when a dull blade causes ragged cuts mid-experiment.
Frequently Asked Questions
Which Box Top Parafilm® Dispensers are compatible with SKU 120722 replacement blades?
SKU 120722 blades are compatible with the Heathrow Scientific Box Top Parafilm® M Dispensers: 120667 (Blue), 120668 (Purple), and 120758 (White). All three dispenser models use the same 23mm blade slot.
How do I know when it's time to replace the blade in my Box Top Dispenser?
Replace the blade when Parafilm® M tears unevenly, requires extra force to cut, or leaves a ragged edge instead of a clean straight cut. Dull blades can also cause the film to stick to the blade rather than releasing cleanly after cutting.
How many replacement blades come in a pack, and what are they made of?
SKU 120722 includes 3 replacement blades per pack. The blades are stainless steel, 23mm, and are designed for the safety sliding mechanism built into all Heathrow Scientific Box Top Parafilm® Dispensers.
Are these blades safe to handle during replacement?
The blades are designed to operate within the dispenser's enclosed safety slider and should be handled carefully during changeover. Always follow standard lab safety practices when handling any sharp instrument.
