1.25 mL, Gastight Syringe, Bubble Free Prime (BFP, 5/16"-28), PN: 69005-40 Details

Hamilton's  1000 series, Gastight, Half-Height, Long-Life #1002 Bubble Free Prime (BFP, 5/16"-28) Syringes with X-Style plunger features a conical plunger tip which extends through the threaded termination of the syringe and into the valve. This unique design expels the air from the syringe and valve decreasing the number of cycles required to prime the fluid path. 

This series of syringes is ideal for dispensing both liquids and gases.  Long-Life Half-Height Syringes are designed for durability and precision. Featuring a plunger tip made from Ultra High Molecular Weight Polyethylene (UHMWPE), this syringe offers superior resistance to abrasion. It is specifically developed to withstand extreme and harsh conditions. With a 30 mm stroke length, it is compatible with Hamilton's PSD/ 4 Syringe Pumps, making it ideal for applications requiring precise liquid handling and robust performance in demanding environments. 
 

Longlife Polymeric Plunger Tip

  • Crafted from Ultra High Molecular Weight Polyethylene (UHMWPE) for exceptional abrasion resistance.
  • Engineered to endure extreme and harsh conditions.

Bubble Free Prime Plunger Tip

  • Features a conical plunger tip that extends through the 5/16" -28 threaded termination and into the valve.
  • This unique zero dead volume design expels air from the system and reduces the priming cycles required to eliminate air bubbles.

  • Gastight Syringes Ensures Integrity of Environment Sensitive Catalysts (or Samples)

    For such, we utilize highly reactive catalysts that are in many cases air and moisture-sensitive. Gastight Hamilton syringes are essential to maintaining the catalyst integrity and, therefore, ensuring reproducible and trustable results.

FAQ

What is the difference between Bubble Free Prime (BFP) Syringes and Luer Lock (TLL) Syringes?

For any syringe pump, the key to achieving the most accurate dispenses 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 to prime. The Bubble Free Prime (BFP) syringe features a conical plunger tip which expels the air from the syringe and valve decreasing the number of priming cycles required to eliminate air bubbles from within the flow path.
