- Drawing Needle
- 18-20 gauge, 1-1.5 inch
- Withdrawing bacteriostatic water from sealed vial
- Reduces vacuum pressure, allows rapid liquid transfer without excessive plunger force
- Required for reconstitution; prevents vial stopper deformation
- Transfer Needle
- 25-27 gauge, 1 inch
- Injecting bacteriostatic water into peptide vial
- Slow, controlled flow minimizes shear force on lyophilized peptide
- Prevents peptide denaturation during reconstitution
- Insulin Syringe (0.3ml)
- 29-31 gauge, ½ inch, integrated needle
- Dosing volumes <30µl with maximum precision
- Zero dead space; graduated in 1µl increments
- Best choice for micro-dosing protocols
- Insulin Syringe (0.5-1ml)
- Dosing volumes 30-100µl
- Integrated design eliminates hub dead space
- Standard choice for most kisspeptin research protocols
- Luer-Lock Syringe + Detachable Needle
- 1-3ml syringe, 25-30 gauge needle
- Reconstitution or dosing when needle gauge flexibility is required
- Interchangeable needle allows gauge adjustment
- Dead space of 5-10µl per draw; avoid for precision dosing
