Microliter syringes are used with liquid only. They feature a stainless steel plunger which is individually fitted to the glass barrel. The result is a liquid tight seal with nearly frictionless movement. These syringes are ideal for organic samples that are not prone to precipitation, crystallization, or bonding with glass. Plungers and barrels are not interchangeable or replaceable. The 700 series syringe is the original hand-fitted Hamilton® syringe. The stainless steel plunger is manufactured to fit the glass barrel with a tolerance less than three thousandths of a millimeter, resulting in unsurpassed syringe life. This series of syringes is ideal for dispensing volumes from 0.5 µl up to 500 µl. A variety of different terminations and needle options are available.
