Hamilton Microliter Syringe Series

Explore Hamilton Microliter syringe series for low-volume liquid handling, precise manual injections, and chromatography-ready analytical workflows.

Hamilton Microliter Syringes are precision liquid-handling instruments designed for applications that require accurate, reproducible sample delivery in chromatography and analytical laboratories. Chrom Tech supplies Hamilton microliter syringe configurations across the 7000, 600, 700, 800, and 900 series, helping laboratories select the right syringe design based on sample volume, handling preference, precision requirements, and workflow demands.

Hamilton positions Microliter syringes as liquid-only syringes featuring a stainless steel plunger fitted to a precision glass barrel. These syringes are intended for homogeneous liquid samples and are widely used for HPLC, GC, microinjection, and other analytical workflows where dependable volume delivery and smooth plunger movement are essential.

Built for Precision Liquid Handling

Hamilton Microliter syringes are designed to deliver precise liquid volumes across a broad range of laboratory applications. The fitted plunger-and-barrel construction supports accurate dispensing and repeatable injections, making these syringes a strong choice for analytical methods where consistency and low-volume control are important.

700 Series: The Original Fitted Syringe

The 700 series is Hamilton’s original Microliter syringe platform and remains a widely used standard for ultra-precise low-volume liquid handling. Hamilton describes this series as a fitted syringe with a stainless steel plunger individually matched to the glass barrel, giving it a smooth feel and strong everyday performance for chromatography, titration, and related manual workflows.

600 Series: Half-Stroke, Low-Volume Control

The 600 series is designed for extremely low-volume dispensing and is described by Hamilton as similar to the 700 series, but with half the stroke length and a reinforced stainless steel plunger. This design supports one-handed operation and gives laboratories an effective option for very small liquid volumes where controlled manual handling is important.

800 Series: Reinforced Plunger Design

Hamilton positions the 800 series as the reinforced plunger version of the original 700 series. This series is well suited for laboratories that want the familiarity of a fitted Microliter syringe with added plunger durability and a holder design intended to help reduce barrel heating during handling.

900 Series: Economical Small-Volume Dispensing

The 900 series is presented by Hamilton as the economical version of the 800 series. These syringes use a permanently attached holder to support accurate routine small-volume dispensing while reducing initial cost, making them a practical option for laboratories that need reliable performance in a cost-conscious format.

7000 Series: Zero Dead Volume Design

The 7000 series is engineered for highly sensitive applications where maximizing sample utilization is important. Hamilton describes this series as a zero dead volume design using a fine tungsten plunger wire that extends through the full needle length, helping drive sample completely through the needle for chromatography, microdosing, and other demanding low-volume workflows.

Wide Configuration Flexibility

Across these Microliter syringe families, laboratories can choose from multiple volumes, needle styles, and termination options to match specific instruments and injection techniques. This flexibility helps users align syringe selection with sample type, injection port design, and preferred manual handling style without compromising analytical precision.

Best for Homogeneous Liquid Samples

Microliter syringes are best suited for homogeneous liquid samples that are free from particulates. In applications involving residue-forming samples or more difficult matrices, proper cleaning and maintenance remain important for preserving smooth plunger movement, minimizing carryover, and extending syringe life.

As an authorized distributor, Chrom Tech helps laboratories select the right Hamilton Microliter Syringe series based on required volume range, syringe construction, injection style, and application sensitivity. Whether your workflow calls for a 600, 700, 800, 900, or 7000 series syringe, Chrom Tech can help match the right Hamilton configuration to your analytical method.

Key Definitions ▸
Microliter Syringe
A precision liquid syringe designed for accurate manual handling of very small sample volumes in chromatography and analytical laboratory workflows.
Fitted Syringe
A syringe construction in which the plunger is individually matched to the glass barrel to create a smooth seal and highly controlled liquid movement.
Half-Stroke Syringe
A syringe design with reduced plunger travel that helps support fine control for very low-volume dispensing and one-handed manual operation.
Reinforced Plunger
A strengthened plunger design used to provide additional support during injection, especially in small-volume syringes where bending risk can be greater.
Zero Dead Volume
A syringe design intended to push sample fully through the needle path so little or no sample remains trapped at the end of dispensing.
Plunger-in-Needle Design
A syringe configuration in which a fine plunger wire extends through the needle to maximize sample delivery and reduce residual volume.
Tungsten Plunger
A very fine, durable plunger wire material used in specialized low-volume syringe designs where precise sample displacement is required.
Built-In Syringe Holder
A permanently attached holder designed to protect the syringe, improve handling, and help reduce heat transfer from the user’s hand to the sample.
Homogeneous Liquid Sample
A uniform liquid sample without particulates or separated phases, typically best suited for fitted Microliter syringe performance.
Frequently Asked Questions ▸
What are Hamilton Microliter Syringes used for?
Hamilton Microliter Syringes are used for precise manual liquid handling in chromatography, microinjection, titration, and other analytical laboratory workflows.
What volume range do Hamilton Microliter Syringes cover?
Hamilton states that the Microliter syringe family covers volumes from 0.05 µL to 500 µL, depending on the syringe series and configuration.
What is the difference between the 600 and 700 series?
The 700 series is Hamilton’s original fitted Microliter syringe. The 600 series is a half-stroke version designed for very low-volume dispensing and one-handed operation.
What makes the 800 series different from the 700 series?
Hamilton describes the 800 series as the reinforced plunger version of the 700 series, giving additional support for small-volume plungers that may be more prone to bending during injection.
What is the 900 series best suited for?
The 900 series is an economical Microliter syringe option with a permanently built-in holder, making it a practical choice for routine small-volume liquid handling.
Why would a lab choose the 7000 series?
A lab would typically choose the 7000 series when it needs zero-dead-volume performance for sensitive applications. Hamilton describes this series as using a tungsten plunger wire that pushes sample through the full needle length.
Are Microliter Syringes best for homogeneous liquid samples?
Yes. Microliter Syringes are best suited for homogeneous liquid samples. Samples with particulates or residue-forming components may require more careful cleaning and maintenance to preserve syringe performance.
Does Chrom Tech help with Microliter syringe selection?
Yes. Chrom Tech can help identify the right Hamilton Microliter syringe series based on sample volume, application sensitivity, handling preference, and the level of plunger support or zero-dead-volume performance your workflow requires.
