Hamilton syringes are manufactured to be accurate within ±1% of nominal volume, and with precision within 1%, measured at 80% of total scale volume. The design of the barrel and plunger dimensions assures high levels of accuracy and precision. The Hamilton Company Quality System is ISO 9001-2000 certified.
When using a Hamilton syringe, the volume in the needle (called dead volume) is considered constant and the volume being dispensed is absolute. The dead volume is maintained throughout aspirate and dispense stages.
No, they are not. Each plunger is fitted to a specific syringe barrel. Be very careful to keep each plunger with its original syringe in order to maximize syringe performance.
GASTIGHT syringes are the most versatile syringes. The plunger is replaceable. Any of the Metal hub, Kel-F or Removable Needle allow for the replacement of needle if they become bent or plugged.
You will need to answer the following questions:
The Digital Syringe is a manual syringe with a digital display which allows you to clearly see the aspirated volume. The Digital Syringe is not automated, it will not dispense with the touch of a button. It operates like a typical syringe, but there is no guessing as to the volume being aspirated or dispensed.
The “s” represents a smaller inner diameter for the needle and a thicker needle wall for better durability. For example, a 26 gauge needle has an outer diameter of 0.46 mm and an inner diameter of 0.26 mm while the 26s gauge needle has an outer diameter of 0.47mm and an inner diameter of 0.13mm. The 26s has half the inner diameter of the 26 gauge needle. The difference in the wall thickness is also nearly doubled with 26s gauge having a thickness of 0.18mm while the 26 gauge is only 0.10 mm.
