The 700 series is the original Hamilton syringe. This series of Microliter syringes is designed to solve the general liquid handling requirements of manufacturing and research laboratories and remains the industry standard. The plungers and barrels are not interchangeable or replaceable.
The 700 series is used for manual and automated GC and HPLC injections. Also, it is used for everyday applications that require accurate measuring and dispensing of liquid.

Microliter syringes are for use with liquids only. They incorporate a hand-fitted stainless steel plunger with a finely bored syringe barrel. These syringes are ideal for homogeneous samples that are not prone to precipitation or bonding with glass.

Under the proper conditions, plunger wear is minimal and the life of a Microliter syringe is almost unlimited. However, when using heterogeneous solutions with a Microliter syringe, the user must be especially diligent about cleaning the syringe after each use.

In some cases, even diligent cleaning is not sufficient and the barrel will become soiled. The deposits on the glass will compromise the tight tolerances between the glass and the plunger resulting in a frozen plunger. Plungers for Hamilton Microliter syringes cannot be interchanged or replaced if damaged. For heterogeneous solutions, a gas tight syringe is the best option.
