Plastic Needles for Autosampler AS421 & AS500
Material: PVC
Quantity: Sets of 2
These needles are crucial components of autosampler systems. Plastic needles are resistant to corrosion and chemical attack from a wide range of solvents and samples encountered in chromatographic analysis. This chemical resistance ensures the integrity of the needle and prevents contamination or degradation of samples during sampling.
Maintenance and replacement:
- Clogging: If the needle is clogged or obstructed, it can affect the flow rate and sample transfer. Symptoms include inconsistent sample volumes or delays in aspiration.
- Visible Damage: Check for visible cracks, chips, or deformation in the plastic needles. Damage can cause leaks or inaccuracies in sample delivery.
- Reduced Performance: If you notice that the autosampler is not aspirating samples as efficiently or accurately as before, it may be due to issues with the needles.
