Syringe 250 µL, Model 1725RN SYR -22s/2"/2. Hamilton
Hamilton's "1700 Series" syringes are the Gastight version of the original 700 Series syringes. This series of syringes is ideal for dispensing volumes from 1 μL up to 500 μL. The needles are removable and are a Hamilton-specific design. The design allows the needles to seat precisely at the zero graduation mark of the syringe.
