A comprehensive range of needles and needle seats for HPLC samplers.

• The needle should be replaced when it becomes bent, burred, or blunt, or when it is leaking or plugged
• Suspect a leak if you notice a trail of buffer crystals on the needle seat
• If the sample contains particles, the needle seat can become blocked, as this is the first restriction that the sample experiences
• If this occurs, try backflushing the needle seat capillary
