Handling & Precautions

• Pre-check glass surfaces for cracks or stress marks before each use.
• Avoid direct placement on very hot surfaces without gradual heating.
• Clean using laboratory-grade detergents; avoid abrasive scrubbing agents.
• Allow the apparatus to cool before washing to prevent thermal stress.
• Do not expose to sudden or extreme temperature changes.
• Compatible with standard autoclave sterilisation within Borosilicate Glass 3.3 limits.
• Handle capillary tubes carefully to avoid breakage or injury.
• Ensure proper alignment of the thermometer or sensors for accurate readings.

 Applications
