Hamilton Gastight Syringes

Hamilton Gastight Syringe Series

Explore Hamilton Gastight syringe series for accurate liquid and gas dispensing across low-volume analytical work, mid-volume transfer, reinforced handling, and large-volume applications.

Hamilton Gastight Syringes are designed for accurate dispensing of both liquids and gases in chromatography and analytical laboratory workflows. Chrom Tech supplies Hamilton Gastight syringe options across the 1700, 1000, 1800, and Super Syringe series, helping laboratories match the right syringe platform to sample type, volume range, and handling requirements.

Gastight syringes use a precision-machined polymer plunger tip to create a leak-free seal inside the syringe barrel. This construction makes them especially useful for heterogeneous liquids, volatile samples, viscous samples, and gas-handling applications where minimizing evaporation, leakage, and residue buildup is important for consistent performance.

Why Choose a Gastight Syringe

Compared with a fitted metal-plunger liquid syringe, a Gastight design helps wipe the inside of the barrel during dispensing, reducing the chance of deposits building up and helping move more of the sample through the syringe. This makes Gastight syringes a strong choice when difficult samples or gas-tight handling conditions are part of the workflow.

1700 Series

The 1700 Series is the low-volume Gastight platform for precise dispensing from the microliter range. It is well suited for chromatography and analytical applications that require leak-free handling of small sample volumes with flexible configuration options.

1000 Series

The 1000 Series extends Gastight performance into the mid-volume range and is commonly used when larger liquid or gas volumes must be dispensed accurately. This series is a practical option for laboratories that need more capacity while still maintaining the benefits of a Gastight seal.

1800 Series

The 1800 Series provides a reinforced Gastight syringe platform for workflows where plunger durability is especially important. This makes it a strong option for laboratories that experience more frequent plunger stress in low-volume or repetitive dispensing applications.

Super Syringe

The Super Syringe platform is designed for very large Gastight dispensing volumes. It is useful in applications where large-volume liquid or gas transfer is needed with accurate, reliable syringe-based control rather than small-volume analytical injection.

Well Suited for Liquids, Gases, and Difficult Samples

Gastight syringes are commonly selected for HPLC, GC, analytical chemistry, sample transfer, and other workflows where gases or challenging liquid samples must be dispensed with minimal leakage. Their sealing design also makes them useful when working with volatile compounds or samples that may otherwise leave deposits inside a standard syringe barrel.

Broad Volume Range and Configuration Flexibility

Across the 1700, 1000, 1800, and Super Syringe families, Gastight syringes cover a very broad working range from very small analytical volumes to large dispensing tasks. Different terminations, needle options, and syringe styles help laboratories match the syringe more closely to the instrument, sample, and dispensing technique being used.

As an authorized distributor, Chrom Tech helps laboratories select the right Hamilton Gastight Syringe series based on sample characteristics, volume range, and dispensing requirements. Whether your workflow calls for a compact 1700 Series, mid-volume 1000 Series, reinforced 1800 Series, or large-volume Super Syringe, Chrom Tech can help match the right Gastight solution to your method.

Key Definitions ▸
Gastight Syringe
A syringe designed for leak-free dispensing of liquids or gases using a polymer plunger tip that seals tightly against the barrel wall.
PTFE Plunger Tip

1700 Series
A low-volume Gastight syringe platform intended for precise dispensing of gases and liquids in analytical and chromatography workflows.
1000 Series
A mid-volume Gastight syringe family used for accurate dispensing of larger liquid and gas volumes while maintaining leak-free performance.
1800 Series
A reinforced Gastight syringe platform designed for low-volume dispensing when added plunger support is needed.
Super Syringe
A large-volume Gastight syringe used for accurate dispensing or transfer of substantial liquid or gas volumes.
Heterogeneous Liquid Sample
A liquid sample containing suspended material or non-uniform composition that benefits from a wiping plunger design during dispensing.

Frequently Asked Questions ▸
What are Gastight syringes used for?
Gastight syringes are used for accurate dispensing of liquids and gases in GC, LC, analytical chemistry, and sample transfer workflows where leak-free sealing is important. :contentReference[oaicite:1]{index=1}
Why choose a Gastight syringe instead of a standard liquid syringe?
A Gastight syringe is often chosen when the sample is volatile, viscous, gaseous, or heterogeneous because the polymer plunger tip provides a tight seal and helps wipe the barrel during dispensing. :contentReference[oaicite:2]{index=2}
What is the 1700 Series best suited for?
The 1700 Series is best suited for low-volume analytical dispensing of liquids and gases, especially in applications where leak-free performance and small-volume precision are important. :contentReference[oaicite:3]{index=3}
What is the 1000 Series used for?
The 1000 Series is used for mid-volume liquid and gas dispensing, covering a broader capacity range while maintaining Gastight sealing performance. :contentReference[oaicite:4]{index=4}
Why would a lab choose the 1800 Series?
A lab would typically choose the 1800 Series when it wants Gastight performance with additional plunger reinforcement for low-volume applications where plunger bending is more likely. :contentReference[oaicite:5]{index=5}
What is a Super Syringe used for?
A Super Syringe is used for large-volume liquid or gas dispensing, including applications such as air sampling, gas standard preparation, and large-volume transfer. :contentReference[oaicite:6]{index=6}
