Agilent Needle Support Insert and Captive Screw

The Agilent G4513-40529 Needle Support Insert and G1946-20168 Captive Screw are a paired set for your research lab's autosampler, ensuring accurate and secure sample handling during chromatography experiments. The needle support insert acts as a guide for the autosampler needle, ensuring precise positioning and preventing bending or damage during sample injection into chromatography columns. This helps prevent inaccurate results. The captive screw (G1946-20168) plays a key role by securely fastening the needle support insert in place. Its captive design keeps the screw attached during installation or removal, preventing it from getting lost and ensuring a secure fit for reliable sample injection in your chromatography work.
