SGE 1MDF-GT Gas Tight 1mL Fixed Needle Injection Syringe with 22 Gauge Beveled Needle

The SGE 1MDF-GT Gas Tight 1mL Injection Syringe is designed for precise handling of liquid and gas samples, making it essential in molecular diagnostics, bioprocessing, and clinical research applications. Constructed from chemically inert borosilicate glass, the syringe features a PTFE plunger tip that enhances chemical resistance and ensures sample integrity during injection or dispensing.

Key technical aspects include:

• Fixed needle design: 22 gauge, 50 mm length, bevel tip glued with epoxy solvent-resistant adhesive to minimize dead volume and eliminate leaks, critical for accurate gas-tight performance.
• Gas tight sealing: Achieved through an interference fit between the PTFE plunger tip and barrel, supporting inert sampling vital in synthetic biology workflows and biopharmaceutical production pipelines.
• Precision and accuracy: Needle aligns with the zero mark on the barrel to improve volumetric precision to within ±1%, supporting meticulous experimental protocols in fluorescence analysis and live-cell imaging sample preparation.
• Autoclavable glass barrel: Supports sterility requirements in biotechnology and molecular cloning laboratories (plunger must be removed prior to autoclaving).
• Interchangeable plungers: Facilitates maintenance and adaptability to different protocols in clinical diagnostics and biomanufacturing environments.

This gas-tight syringe is widely adopted in synthetic biology research and molecular diagnostics, providing reliable and contamination-free sample injections and dispensations critical for analytical chromatography, gas sampling, and bioprocessing. Its compatibility with manual and dispenser/diluter devices makes it versatile for laboratory workflows demanding high inertness and sample integrity.
