Handling & Precautions
- Always assemble components with clean, dry hands to prevent contamination
- Avoid overtightening the aluminum clamp to preserve joint integrity
- Clean using mild detergents or appropriate laboratory solvents; avoid abrasive materials
- Autoclavable at 121°C—allow gradual cooling to prevent thermal shock
- Never expose borosilicate glass to sudden temperature changes or open flames
- Inspect the membrane support surface regularly for cleanliness to maintain filtration accuracy
- Store the assembly in cushioned, dust-free compartments when not in use
