* The chosen frequency may be time-based, for example weekly or injection-based, for example 100 injections. It depends on
your individual application and needs. The time and injection-based EMF counter can be customized.
Do not open the top cover or remove the cartridge without lowering the lifts. Use the
N O T E
function maintenance position from the tools section of the Lab Advisor. Careless opening
may lead to floating of electrodes with buffer or sample which leads to contamination or
carry-over.

Typical frequency Notes
• Use the Clean Level Sensor task to remove salt
deposits inside the tubing system.
• Keep a water-filled parking vial in carousel
position 49.
• Occasionally replace the parking vial in position
49 with water or buffer.
• Inspect for bending if clogged.
• Remove persistent clogging by a syringe flush
with water/isopropanol or use ultrasonic
device.
• Inspect O-ring in cap for damage, remove salt
deposits.
• Do not use buffer reservoir for long-term
storage (prevents oxygen saturation and
bacteria from growing).
• Remove liquid from waste bottle.
• Inspect and clean (especially if absorbing
buffers have been used).
• Replace when dirty.
• Do not overuse vial caps (especially the PEO
caps).
• Inspect for damage.
