Hamilton Gastight glass syringes with female 1/4-28 UNF tip in PEEK for easy connection to threaded fittings.
1/4-28 fittings are often used in microfluidics for connecting rigid tubing (PTFE, FEP, PEEK, etc.).
Available from 25 µL to 50 mL, with 1/4-28 tip.
Hamilton syringes are indisputably the best in terms of precision and quality. These glass syringes with a female 1/4-28 PEEK connectors can be used along with syringe pumps in microfluidic applications for liquids and gases. The female connector ensures a simple and efficient connection to the microfluidic system.
Chemically inert, the syringes have an extreme resistance to acids (affected by sulfuric acid), alkalis, greases, solvents, hydrogen peroxide, demineralized water, or hot steam.
We offer these syringes with volumes ranging from 25 µL to 50 mL.
