Handling & Precautions

• Safe Use: Avoid operating without cooling water. Ensure the vacuum pump and glass joints are securely connected. Do not exceed the recommended flask rotation speed.
• Cleaning Instructions: Use non-abrasive cleaners; rinse with distilled water. Remove residues immediately to avoid buildup.
• Autoclaving/Heating Limits: Borosilicate Glass 3.3 tolerates high temperatures; avoid sudden cooling. The heating bath should operate within the manufacturer-recommended range.
• Dos: Inspect for cracks before use. Lubricate glass joints with suitable vacuum grease. Keep the condenser free from blockages.
• Don’ts: Do not apply excessive vacuum beyond rated capacity. Avoid bending or twisting glass tubing.
• Best Practices: Maintain pump oil and check seals regularly. Store glassware in padded racks after cleaning.
