700 Series MICROLITER® Syringes, Hamilton

The 700 series syringe is the original hand-fitted Hamilton syringe

Cemented needles (N) for low volume syringes feature the needles 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. Syringe 60373-775 features a special cemented needle (SN) with a termination that is the same as a cemented needle termination, except it allows for a variety of user-defined gauges, lengths, and point styles to be attached. Not autoclavable.

Removable needles (RN) are a Hamilton-specific design. This 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) needles 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 increases the dead volume in the syringe, which may not be appropriate for some applications. Autoclavable when disassembled to 115°C (239°F).

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. This series of syringes is ideal for dispensing volumes from 0.5 –500μL. Each syringe is manufactured to achieve the highest level of accuracy and precision possible. Fluid path is SST and borosilicate glass. A variety of different terminations and needle options are available.

Needle Point style 2 is a sharp, beveled, curved, non-coring needle point recommended for septum penetration. Point style 3 is a blunt needle point for use with HPLC injection valves and sample pipetting. Point style 5 is a conical needle with side port for penetration of septa, thin-gauged vinyls, and plastics without coring. Point Style AS is a special conical style needle point used on autosampler syringes. The non-coring needle point is recommended for septum penetration.
