The 700 series syringe is the original hand-fitted Hamilton syringe. This series of syringes is ideal for dispensing volumes from 0,5 to 500 µl. The stainless steel plunger is manufactured to fit the glass barrel with a tolerance smaller than 100 millionths of an inch, resulting in unsurpassed syringe life. Each syringe is manufactured to achieve the highest level of accuracy and precision possible.

• Fluid path is stainless steel and borosilicate glass

Cemented needle (N): Cemented needles for low volume syringes are cemented into the glass syringe barrel at a point corresponding to the zero graduation mark. With this termination, dead volume is limited to the internal volume of the needle. Not autoclavable. Needle gauge is determined by the syringe volume and are not user-selectable.

Removable needle (RN): The design allows the needles to seat precisely at the zero graduation mark of the syringe. Users can select the needle gauge, length, and point style to optimize the syringe for custom applications. This termination also allows for a removable needle without increasing the dead volume of the syringe and is ideal when there is a risk of the needle clogging. Autoclavable when disassembled. Repeated autoclaving will shorten syringe life.

Luer tip (LT): Luer tip syringes feature needles that are removable and fit over a ground glass hub which is tapered in the shape of a male Luer. This termination will accept most hypodermic needles but was designed specifically for use with Hamilton Kel-F needles. This termination also increases the dead volume in the syringe, which may not be appropriate for some applications. Autoclavable when disassembled.

Needle point style 2: Sharp, beveled, curved, non-coring needle point recommended for septum penetration.

Needle point style 3: Blunt needle point for use with HPLC injection valves and for sample pipetting.

Needle point style 5: Conical needle with side port for penetration of septa, thin-gauged vinyls, and plastics without coring.

Needle point style AS: Special conical style needle point used on autosampler syringes the non-coring needle point is recommended for septum penetration.
