Standards & Certifications

• EN 571 — European standard for non-destructive testing materials and vacuum sealing applications

Features & Benefits

1. Vacuum-Tight Seal
   Provides a reliable vacuum-tight seal on ground-glass joints, desiccators, bell jars and other laboratory vacuum apparatus — ensuring maintained vacuum integrity during experiments and processes.
2. Eliminates Need for Lubricants & Vacuum Greases
   Replaces the need for conventional lubricants and vacuum greases on ground-glass joints — reducing contamination risk, simplifying setup and improving cleanliness in laboratory environments.
3. Releases Readily After Long Periods
   Despite forming a vacuum-tight seal, the tape releases cleanly and readily even after extended periods under vacuum — making disassembly and cleaning of glassware quick and straightforward.
4. Wide 25mm Format
   Wider 25mm tape width provides better coverage across larger joint surfaces, flanges and vacuum connections — ideal for laboratory glassware and industrial vacuum equipment.
5. Ultra-Thin 0.075mm Thickness
   Ultra-thin profile allows clean, conforming application on precision ground-glass surfaces and fine-thread connections without adding excessive bulk.
6. Generous 12m Length
   Long 12m roll provides extensive coverage for laboratory and industrial sealing applications — reducing the frequency of roll changes during intensive work.
7. PTFE Material — Chemically Inert
   Chemically inert PTFE construction is resistant to virtually all laboratory chemicals, solvents and reagents — ensuring the tape does not contaminate or react with the materials being handled.
