250 µL, Microliter Syringe, Removable Needle (RN), PN: 7646-01 Details

Hamilton's 800 series, Microliter # 825 Removable Needle (RN) Syringe is a reinforced plunger version of the 700 series syringe. This syringe also features a blue Syringe Holder attached to the flange. This unique component safeguards against any heat transfer from the barrel, ensuring accurate dispensing. The reinforced plunger provides crucial support to delicate small-volume plungers, preventing bending and maintaining injection integrity.

Syringe Holder Design

  • Integrated blue holder on the flange prevents heat transfer to the syringe barrel.
  • Prevents dispense inaccuracies from sample heating.

Reinforced Plunger Style

  • Engineered to safeguard delicate plungers in small volume syringes, preventing bending of their fine plunger wires.
  • Increases the overall durability of the syringe, providing a reliable instrument for repeated use.

  • Microliter Syringes for Accurate Analysis of Reactive Chemical Species

    We commonly use microliter syringes for the preparation of reactions as they allow for the precise addition of reagents, and in addition, are inert to many of the redox reagents we use in our chemistry. We can also accurately transfer reactive species for chemical analysis without significant sample degradation. As we move into a new phase of our research, Hamilton syringes will allow for the accurate analysis of reaction products. This will include the GC analysis of N2, H2, and small molecule activation products from C-N bond forming chemistry.

FAQ

How can I sterilize my syringe?

Chemical sterilization is the preferred method for all Hamilton products. Autoclaving syringes should only be used as a last resort and only where specifically stated. Syringe sterilization is not straightforward. Not all syringes can be autoclaved.

FAQ

What is the difference between a Syringe and a Calibrated Syringe?

These syringes are manufactured the exact same way. The Calibrated Syringe is a serialized syringe including a Certificate of Calibration traceable to NIST, whereas the Syringe does not include a certificate. Hamilton Company offers a recalibration service for Calibrated Syringes. All Calibrated Syringe part numbers begin with CAL.
