Hamilton 1800 Series Gastight Syringes

Reinforced low-volume PTFE-tipped syringes designed for accurate liquid and gas dispensing with added plunger protection

Hamilton 1800 Series Gastight Syringes

Hamilton 1800 Series Gastight syringes are designed for accurate, leak-free dispensing of liquids and gases in analytical, chromatography, and laboratory workflows where plunger protection is especially important. The 1800 Series is the Gastight version of the Hamilton 800 series platform and is built to provide the same core liquid-handling capabilities associated with the 1700 Series while adding a reinforced syringe holder design that helps protect against plunger bending and breakage. Chrom Tech supplies Hamilton syringes as an authorized distributor, helping laboratories choose the right 1800 Series configuration for precise sample transfer, injections, standards preparation, and instrument-related workflows.

The 1800 Series uses a PTFE plunger tip and precision glass barrel to create a tight Gastight seal for controlled handling of both liquids and gases. This design helps reduce evaporation, leakage, and sample loss while supporting dependable low-volume performance. A key differentiator of the 1800 Series is the blue syringe holder, which helps protect the plunger, reduces heat transfer from the user’s hand, and gives the operator added control over dispensing speed. For laboratories that want the sealing benefits of a Gastight syringe with added plunger support, the 1800 Series is a practical option.

Why Hamilton 1800 Series Gastight Syringes Are Used

In many analytical workflows, syringe reliability depends not only on sealing performance but also on protecting the plunger from damage during routine handling. The Hamilton 1800 Series is used when laboratories need accurate low-volume Gastight dispensing along with a more protected plunger design. The integrated syringe holder helps reduce the risk of bending or breakage while also improving user control during aspiration and dispense steps. This makes the series especially useful in applications where repeatable motion and operator handling can affect consistency.

Like other Hamilton Gastight syringe families, the 1800 Series is suitable for both liquid and gas handling. The PTFE plunger tip creates a leak-free seal inside the barrel, helping maintain sample integrity during aspiration, transfer, and injection. This is valuable when working with volatile samples, gas standards, or other applications where leakage and evaporation can affect analytical performance. The reinforced holder design adds another layer of practical durability without changing the core Gastight handling benefits.

Reinforced Design for Plunger Protection

The defining feature of the 1800 Series is its reinforced holder design. This blue holder supports the syringe plunger and helps protect it from accidental bending or blowout during use. In laboratory environments where syringes are handled frequently or used in repetitive workflows, this added protection can improve usability and extend service life. The holder also reduces direct heat transfer from the user’s hand to the syringe, which can support more consistent performance in sensitive analytical work.

Because the 1800 Series is based on the same general Gastight liquid-handling concept as the 1700 Series, it remains a strong choice for laboratories that want dependable precision but prefer a syringe design with more mechanical support. This makes it especially relevant for users who value durability, handling control, and low-volume accuracy in the same platform.

Controlled Gastight Performance for Low-Volume Work

The 1800 Series is designed for low-volume dispensing where accurate, controlled delivery is critical. The Gastight PTFE plunger tip helps create a tight seal within the barrel, supporting reliable aspiration and controlled dispense speed across analytical tasks. The added syringe holder also gives the user more control over plunger movement, which can be beneficial in applications requiring careful, deliberate sample delivery.

For chromatography laboratories and other analytical settings, this combination of Gastight sealing and reinforced plunger support makes the 1800 Series well suited for tasks such as manual injections, standards preparation, sample transfer, and other precision dispensing workflows. When laboratories need a Gastight syringe that helps reduce plunger damage while maintaining accurate liquid and gas handling, the 1800 Series is a strong fit.
