Hamilton's '600 Series' syringes are a rugged, durable, and long lasting half stroke version of Hamilton’s original 700 series syringes.
They have a reinforced plunger which prevents plunger bending. Each plunger is individually fitted to the glass barrel and cannot be interchanged between syringes.
This series of syringes is ideal for dispensing volumes from 0.25 µL up to 5 µL. Because of the shorter stroke length, the 600 series syringes can be used for one-handed applications.
