Seal wash supplies help increase seal lifetime when highly concentrated buffer solutions are used.

• Water/isopropanol (90/10) is recommended as the wash solvent
• Wash the flow path with clear solvent after using concentrated buffers to increase the piston and seal lifetime
• Routine pump maintenance should be done on a regular basis to keep your Agilent LC system performing at its optimum

Agilent seal wash kits include all supplies needed to modify the pump head to allow flushing the back of the seal with a wash solvent. The routine use of highly concentrated buffer solutions (100 mM) will reduce the life of seals and pistons in your pump. The use of seal wash in HPLC systems helps to increase the performance and lifetime of the piston seals.
