How to open a flea pipette? - in detail
Opening a flea pipette requires careful handling to avoid spillage and preserve the specimen. Follow the steps below precisely.
- Hold the pipette firmly by the plastic barrel, keeping the glass tip pointing downward.
- Locate the recessed seam near the base of the glass tip; this is the fracture line designed for separation.
- Apply gentle, even pressure with the thumb and forefinger on opposite sides of the seam. The glass will crack cleanly along the pre‑scored line.
- Once the tip separates, pull it away from the barrel while maintaining a slight upward angle to keep the liquid inside the barrel.
- Inspect the broken tip for any shards; discard it according to laboratory safety protocols.
- If a new tip is required, attach a sterile replacement by aligning the neck of the tip with the barrel opening and pressing until a snug fit is achieved.
During the operation, wear protective gloves and eye protection. Work over a absorbent pad to catch accidental drops. Ensure the work surface is level to prevent the liquid from moving toward the fracture line before opening. After the tip is removed, seal the barrel with the provided cap to prevent evaporation.
