The 700 series syringe is the original hand-fitted Hamilton syringe. 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 in this series.
What are the most versatile syringes made by Hamilton?
Gastight syringes are the most versatile syringes. Plungers are replaceable if they get bent. Any of the Metal hub, Kel-F or Removable needle allow for the replacement of needle if they become bent or plugged.

How can I sterilize my syringe?
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 0.47 mm and an inner diameter of 0.13 mm. The 26s has half the inner diameter of the 26 gauge needle. The difference in the wall thickness also nearly doubled with 26s gauge having a thickness of 0.18 mm while the 26 gauge is only 0.10 mm.
The syringe cleaner requires a Variable Autotransformer and we recommended finding the rheostat at an electronics supply house like Newark Electronics. For example: Newark Electronics - P/N 66F3591 or Tenma P/N 72-110
Syringe Selection Guide
The last option to save a syringe with a bent plunger is to buy a Gastight syringe. The plungers can be replaced at a fraction of the cost of a new syringe.
This is the standard, stainless steel plunger found in 2.5 – 500 µL volume Hamilton Microliter syringes. This plunger is hand fitted to the glass barrel to a tolerance of millionths of an inch to create a liquid tight seal ideal for dispensing solvents. When using samples without dissolved particles, the Microliter plunger has an almost unlimited lifespan because there are no wear surfaces. Also, these plungers are not interchangeable between syringes or replaceable due to the custom manufacturing process.
This plunger is exclusively for 0.5 – 5 µL volume 7000 series syringes. The end of the plunger has a tungsten wire extension that fits the entire length of the needle all the way to the tip, resulting in zero dead volume. This 7000 series syringe is used for dispensing minute liquid volumes.
Hamilton manufactures a variety of Gastight plungers depending on the intended use of the syringe. All Gastight plungers are made of stainless steel or aluminum and feature a polymer plunger tip, often PTFE. These plungers can be used for manual or automated applications with liquids or gases. The plungers are interchangeable and replaceable for 10 µL – 100 mL volume syringes.
Manual plungers come in two designs, one features a standard dome button and the other features a threaded plunger button. Syringes smaller than 1 mL have a stainless steel plunger for syringes, as shown in the picture on the left. Manual plungers 1 mL and larger are coated with PTFE and come with a threaded hole that allows them to be mounted into automated syringe pumps, which is demonstrated by the image on the right.
This plunger is used for syringes 500 µL and smaller intended for use in an automated syringe pump. A special plunger button protects the delicate plunger wire by stopping the pump at the zero line before damaging the tip. The stop also provides a 6-32 threaded hole that is used to mount the plunger into the syringe drive.
This plunger is used on XP-3000 modular digital syringe pumps and has a stop to limit damage to the plunger tip. This plunger is for half-height syringes with a 30 mm stroke length.
This plunger is used on the XL-3000 modular digital syringe pumps and has a stop to limit damage to the plunger tip. This plunger is for full-height syringes with a 60 mm stroke length.
This plunger features a stop and a back bushing. The back bushing increases the plunger tip life, maintains proper plunger alignment and reduces the particles generated by plunger and glass contact.
This plunger is used exclusively in syringes for Microlab 600 diluters and dispensers. The plunger features a conical plunger tip that extends through the threaded termination of the syringe into the Microlab 600 valve. This design helps remove air from the system and reduces the priming cycles required.
Small volume syringes require extremely small plunger wires. For uses that are prone to bending and breaking these small plungers, it is recommended using a reinforced plunger. These plungers are available in both Microliter and Gastight versions in the 800 and 1800 syringe series respectively.
Several different needle point styles are offered on Hamilton syringe and needle products depending on the application. The correct point style varies depending on the intended application. Below are a few examples of common applications.
Manual GC Injections: Historically a Point Style 2 was required to achieve efficient septum penetration with minimized coring. With Hamilton’s new line of GC septa there is evidence that indicates the Point Style AS will consistently extend septa life by as much as 10-fold.
Manual HPLC Injections: Most manual injection valves are designed to be used with a 22 gauge Point Style 3 needle.
Drawing Sample: Any point style will efficiently draw a sample, but when it is important to get the last drop out of a vial use Point Style 3 or AS to reach all the way to the bottom.
Animal Injections: Animal injections require the sharpest needle possible. The recommended needle point style for this application is a Point Style 4 at a 12° bevel. For applications where injection site depth is critical or the target is small, a more vertical bevel as shown below, such as a 30 or 45°, is suggested.
Bevels for the point style 4 needle may vary from 12-60°.
Note: Syringes and needles manufactured by Hamilton Company are intended for scientific research and laboratory use only and are not intended for human in vivo use.
Volumes are based on 60 mm scale length except models 1100 which are based on 120 mm scale length. O.D. dimensions are nominal and typical, I.D. dimensions are theoretical.
