System Cleaning
When the
intelliPATH
software notifies operator that cleaning is necessary, follow on-screen instructions. This cleaning
cycle should be performed at a minimum of once per week if the user has not reached the maximum slide count allowed.
Daily
• Rinse the used racks in tap water after every run.
• Using a DI squirt bottle, simply rinse the built-up buffer off the gap between the rear frame of the instrument
and the slide tray rails (where the rails meet the back of the instrument).
• Add a DI Water wash at the end of every protocol. Probably the most effective way to keep your instrument clean.
• Always use DI water with Tween 20 and Proclin such as Biocare’s Automation Tween 20 (TWA 20).
Weekly
Note:
This procedure cleans only the reagent ‘probe’ (pipettor) and waste-reservoir drain.
• Weekly or every 250 slides, perform the DAB Away cleaning as required or, at least, once a week to clean the
reagent Probe and Waste Reservoir Drain.
• Using a soft brush and a non-abrasive, non-corrosive cleaning agent, gently clean each rack (especially clips),
then rinse thoroughly in tap water. Do not bend clips in process.
• Use a Kimwipe dampened with DI water to wipe the Liquid Level Sensor, the Barcode Reader and the outside
of the probe.
Monthly
• Disinfect carboys and internal supply lines using a 10% Lysol solution.
• Fill Buffer 1, DI and Buffer 2 carboy (if used) with at least 2L of a 10% Lysol solution.
• Shake the carboys so the walls of the carboys are well washed.
• Log in to the IntelliPATH system.
• Execute the Stainer Application.
• Within the tools menu, click prime probe and prime the probe for 30 seconds.
• Within the tools menu, click on Drain Waste and Prime Buffers.
• Click the “Prime Buffer” radio button; sequentially prime all the Lysol solution out of each carboy.
Use the “Drain Waste” function to drain the waste into non-hazardous carboy as needed.
• After all the solution has been primed through the instrument lines, dump out the remaining solution, and rinse
the carboys 2-3 times with DI water.
• Fill each carboy with at least twice as much DI water (4-5L) as Lysol solution and repeat the above steps. Be
certain to prime the probe for at least 2 minutes. This will ensure your instrument is well rinsed.
• Soak removable components in a 10% Lysol solution.
• Remove the slide racks and soak in solution. Scrub if necessary, paying particular attention to the slide clips.
• Remove the splash guard dividers and soak in solution
• Remove the slide rails by unscrewing the thumb screws – soak in solution. Scrub if necessary, paying particular
attention to the rail guide area.
• With all components removed, clean the interior of the stainer.
• White stains are typically Buffer buildup and can be rinsed with DI water.
• Brown stains are DAB stain. DAB stain can be removed with DAB Away.
