Periodic Maintenance
Inspect and clean the delivery nozzles at each IDF and SDF station
On a monthly basis (or more frequently depending on usage), follow the steps below to inspect and clean the delivery nozzles.
1. Observe the spray capability during the rinse cycle of an assay.
2. Remove any plugged nozzles by pulling and turning them (they are friction fit to the delivery tubes).
3. Clean out the six holes using the Spray Tip Cleaning Tool (part # 8130) to regain unobstructed fluid passage.
4. Clean out any foreign matter left by the process (pressurized air may be used to blow out the holes).
5. Reinstall the delivery nozzles by turning and pushing them onto the delivery tubes.
Inspect and clean chemical containers and filters
On a monthly basis (or more frequently depending on usage), follow the steps below to inspect and clean the chemical
containers and filters.
1. Inspect the containers and container filters (at the end of the tubing inside each container) checking for any
precipitate, particles, or foreign matter that may be plugging the filters or settled at the bottom of the container.
2. Clean the filters by running them under fast running water.
3. Rinse the containers out with water and let air dry as needed.
Regularly clean the instrument surfaces
Wipe down the surface of the instrument whenever spills occur or splatters are observed.
Inspect silicone tubing for wear or leaks
On a monthly basis (or more frequently depending on usage), follow the steps below to inspect the silicone tubing.
1. With the instrument connected to pressurized nitrogen, inspect the pressurized air lines. Listen for any audible
leaks and check for cracks or kinks.
2. Replace tubing as needed.
If after running this instrument you plan to leave it unused for 1 week or longer, you
must clear out the fluid lines to ensure proper operation. See “Appendix B –
Instrument Out-of-use Procedure” for more information.
