What is the difference between Bubble Free Prime (BFP) Syringes and Luer Lock (TLL) Syringes?
Bubble Free Prime (BFP) Syringes
For any syringe pump, the key to achieving the most accurate dispense is eliminating all air from the fluid path. Traditional syringes trap approximately 50 μL of air between the tip of the syringe and the valve. For small syringes, this trapped air is the last to leave the syringe and the first to be drawn back in, making them difficult, if not impossible, to prime. The Bubble Free Prime (BFP) syringe features a conical plunger tip which extends through the 5/16"-28 threaded termination and into the valve. This unique zero dead-volume design expels the air from the syringe and valve decreasing the number of priming cycles required to eliminate air bubbles from within the flow path. BFP syringes reduce the amount of wasted solvent required for extended priming cycles and decrease prep time.
BFP syringes are available with both standard polytetrafluoroethylene (PTFE) and long life ultra-high-molecular-weight polyethylene (UHMWPE) plunger tip materials.
Luer Lock (TLL) Syringes
Luer Lock (TLL) syringes feature the standard flat Gastight plunger tip and a male Luer Lock termination. The industry standard male Luer taper is compatible with both Hamilton and most other manufacturer's female Luer Lock connections (hypodermic needles, adapters, valves, etc.). The syringe's male Luer taper seals against a female Luer taper, and a slight twist engages the threads "lock" or secure the connection.
TLL syringes are available with both standard polytetrafluoroethylene (PTFE) and long life ultra-high-molecular-weight polyethylene (UHMWPE) plunger tip materials.
