12.5 mL, Gastight Syringe, Half-Height Instrument Syringe, PN: 5495-55 Details

Hamilton's  1000 series, Gastight Half-Height #1705 PTFE Luer Lock (TLL) Syringes with X-Style plunger are designed for durability and precision. They feature a polymer plunger tip that creates a leak-free seal. 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. 

Polymer Plunger Tip

  • A white polymer plunger tip effectively wipes the glass barrel, creating a leak-free seal.
  • Ensures a Gastight performance, suitable for liquids and gases.

X-Style Plungers

  • The plunger button features a 6-32 threaded hole, commonly used for mounting the syringe into a syringe pump.
  • Syringes with X-Style Plunger Buttons can also be used manually.
Scientific Citations

  • 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 are the most versatile syringes made by Hamilton?

Gastight syringes are the most versatile syringes. Plungers are replaceable if they get bent. Any of the Metal hub, Kel-F or Removable needle allow for the replacement of needle if they become bent or plugged.

FAQ

Can I order a replacement plunger for my syringe?

Most Gastight syringes have replacement plungers available under 'Accessories' on the product page, while Microliter syringes do not. 7000 series modified Microliter syringes have zero dead volume and a small plunger wire, but it's best not to remove the needle or plunger to avoid damaging the wire.

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.
