Cleaning Optimum Ceramic MicroDot Tips
Instructions
Introduction
To precisely dispense accurate, small amounts of fluid, the Optimum
®
Ceramic MicroDot
™
tip has an
extremely small opening. This opening can become clogged or blocked by very small contaminants which
can adversely affect dispensing results.
Tip contamination, particularly in the fluid flow path, is manifested by the following symptoms:
• Poor dispensing
• No fluid flow, caused by clogging of the nozzle orifice
Recommended Cleaning Schedule / Cycles
Cleaning and maintenance intervals vary depending on operating conditions. Testing has shown that MicroDot ceramic tips
can survive 10 cleaning cycles without loss of performance.
Cleaning Tools
• Valve disassembly / reassembly tools (refer to the valve manual)
• Tweezers
• Acetone
• Compressed air supply
• Ultrasonic cleaner
Three Steps for Cleaning MicroDot Tips
(1) Clean the Fluid Path by Purging the Tip
If the tip is not clogged, purge the tip with a cleaning fluid or solvent that is compatible with your dispensing fluid. Purging
can be performed with the tip assembled on the valve or manually if the tip has been disassembled from the valve.
NOTES:
• Refer to the valve manual for disassembly and reassembly procedures.
• The MicroDot tip can withstand repeated purging cycles with acetone. Before using acetone, refer to the Technical Data
Sheet (TDS) or Safety Data Sheet (SDS) for your dispensing fluid to ensure that it is compatible with acetone.
