Hamilton syringes are available in two styles, Gastight and Microliter™, which differ primarily in the design of the plunger. Hamilton syringes are accurate to within ±1% of nominal volume with a precision of 1% at 80% of the total volume. Their stainless steel, borosilicate type I glass or PTFE composition ensures a chemically inert fluid path. Besides the extensive list of Hamilton syringes presented here, we can also supply any other Hamilton syringe.

Frequently Asked Questions (FAQ)
Gastight syringes have a precision machined PTFE plunger tip which provides a tight, leak-free seal for both liquids and gases. Replacement plunger assemblies are available for most Gastight syringes.
Luer Tip Cemented Needle (LTN), Luer Tip Special Cemented Needle (LTSN), Luer Tip (LT), Removable Needle (RN), SampleLock (SL), and PTFE Luer-Lok (TLL)
Syringe Volumes: 1 mL, 1.25 mL, 2.5 mL, 5 mL, 10 mL, 25 mL, 50 mL, 100 mL
- Mid-volume solution for all liquid and gas handling
- Ideal for manual and automated HPLC injections
- Commonly used in syringe pumps and other liquid handling instrumentation
Cemented Needle (N), Special Cemented Needle (SN), Luer Tip Cemented Needle (LTN), Luer Tip Special Cemented Needle (LTSN), Luer Tip (LT), Removable Needle (RN), SampleLock (SL), and PTFE Luer-Lok (TLL)
Syringe Volumes: 10 µL, 25 µL, 50 µL, 100 µL, 250 µL, 500 µL
- Gastight version of the original Hamilton 700 series
- Ideal for low volume gas or liquid handling
- Excellent for manual & automated GC & HPLC injections
- Commonly used in syringe pumps and other liquid handling instrumentation
Cemented Needle (N) and Removable Needle (RN)
Syringe Volumes: 10 µL, 25 µL, 50 µL, 100 µL, 250 µL
- Designed to eliminate the possibility of plunger damage
- Same liquid handling capabilities as the 1700 series but the extended plunger eliminates breakage and allows the user some control over the dispensing rate
- Ideal when the plunger of a 1700 syringe may be bent
Microliter syringes feature a stainless steel plunger which is individually hand-fitted to its matching glass barrel. The handfitting process is finely controlled to create a liquid-tight seal between the barrel and the plunger. Microliter syringes are for use with liquids and incorporate a stainless steel plunger that is individually fitted to its matching syringe barrel. These syringes are ideal for homogenous samples that are not prone to precipitation or bonding with glass. Plungers for Microliter syringes cannot be interchanged or replaced if damaged. If working with heterogeneous samples, we recommend frequent, diligent cleaning, or using a Gastight syringe instead.
Removable Needle (RN)
Syringe Volumes: 2.5 µL, 5 µL
- Robust design
- Consists of two distinct parts: bottom half of the barrel accurately measures the liquid sample and the top half supports the plunger
- Top section of the plunger is thicker to reduce the risk of bending
- Require half of the standard stroke length making them ideal for one-handed operation
- Plungers and barrels are not interchangeable or replaceable
Cemented Needle (N), Special Cemented Needle (SN), Removable Needle (RN) and Luer Tip (LT)
Syringe Volumes: 5 µL, 10 µL, 25 µL, 50 µL, 100 µL, 250 µL, 500 µL
- The original Hamilton syringe
- Still has wide applicability - industry standard
- Solves general liquid handling requirements
- Plungers and barrels are not interchangeable or replaceable
Cemented Needle (N), Special Cemented Needle (SN), and Removable Needle (RN)
Syringe Volumes: 5 µL, 10 µL, 25 µL, 50 µL, 100 µL, 250 µL
- Intended for applications where the plunger on a 700 series syringe might be bent
- Aluminum syringe holder eliminates plunger damage
- A friction screw at the top of the barrel can be adjusted to give the user some control over dispensing speed and prevent the accidental removal of the plunger
- Syringe holder can be fi tted with different barrel/ plunger assemblies to cover a range of volumes
- Excellent for novice users
Cemented Needle (N), Special Cemented Needle (SN), and Removable Needle (RN)
Syringe Volumes: 5 µL, 10 µL
- Economical version of the 800 series
- Contains no replaceable parts, reducing initial cost
- Perfect when a robust syringe is desired and budget is a consideration
Knurled Hub (KH)
Syringe Volumes: 0.5 µL, 1 µL, 2 µL, 5 µL
- For manual and automated GC and HPLC injections
- Employs a tungsten plunger wire inside the needle to accurately dispense ultra-low volumes
- Ideal for everyday applications that require ultra-small measurements of liquid
- Needle is bored to extremely accurate tolerances to accommodate the plunger wire
- When plunger is inside the needle, the standard dead volume inside the needle is eliminated
- Removable needles, PTFE-tipped replaceable plungers
