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.
