Handling & Precautions
Safe Use:
- Ensure the clamp is firmly tightened before applying the vacuum.
- Inspect the glass for chips or cracks before each use.
Cleaning:
- Rinse immediately after filtration to prevent residue buildup.
- Use mild detergents; avoid abrasive cleaners.
Autoclaving/Heating:
- Autoclave only glass and PP components.
- Do not expose the anodised aluminium clamp to prolonged high temperatures.
Do’s & Don’ts:
- Do: Handle glassware with both hands during setup.
- Do: Replace worn silicon corks for optimal sealing.
- Don’t: Use hydrofluoric acid or other agents known to etch glass.
- Don’t: Apply excessive torque to the clamp.
Best Practices:
- Store the assembly dismantled to extend component life.
- Periodically check sealing surfaces for wear.
