Aspiration
Aspiration — The process of drawing liquid into a syringe or pipette, a critical technique for accurate measurement of reconstituted peptide solutions.
What Is Aspiration?
Aspiration is the controlled withdrawal of liquid using a syringe, pipette, or automated system. In peptide research, proper aspiration technique is critical during reconstitution (drawing bacteriostatic water into a syringe), sample preparation (removing supernatant from precipitates), and SPPS (draining wash solvents from resin).
Best Practices
- Vial reconstitution: Insert needle through septum, aspirate slowly along the vial wall to avoid foaming
- Avoid bubbles: Tap syringe to dislodge air bubbles before injecting peptide solution
- Cell culture: Aspirate media carefully to avoid disturbing cell monolayers during peptide treatment
