Up to 15 programs can be saved.
You can select up 5 of your protocols as favorite programs.
As long as the delay step has not yet been completed the finish time can be changed.
In the program mode of the menu, press the Edit button and mark the reagent you wish to have as delay step. Press the button Delay on top of the display. The “delay clock” will appear at the chosen station.
Fill an external bottle (13 ext.) with an appropriate cleaning solvent.
When starting the extended cleaning program, the ASP calls on the operator to insert the external bottle after finishing the first two cleaning steps with station bottles 11 and 12. Follow that order by inserting the external bottle with detergent at station 13 ext. and follow the on-screen instructions. The instrument continues the cleaning cycle and informs you afterwards to insert the previous bottle 13. After your confirmation the ASP will complete the cleaning program.
All cleaning programs are predefined and ensure good cleaning results. They can be minimally modified but not renamed, added or deleted.
It is not possible to remotely fill the wax bath. You can fill the wax bath either with solid paraffin, or with liquid wax.
Recommended reagents for the fixation step are formalin buffered or unbuffered, and formalin saline. Other reagents may damage some components of the instrument. Never use acetone, benzene or trichlorethane! Fixatives containing mercuric salts, acetic or picric acid will shorten instrument life. If you choose to work with such reagents, it is essential to perform a cleaning cycle which contains multiple water rinses after each use to minimize damage.
The anti-reflection clips prevent reflections affecting the level sensor which could falsely initiate error messages.
Every 3 months, unless the ASP is connected to an external fume hood.
A pneumatic (PK) hose with an inside diameter of 8 mm and an outside diameter of 10 mm can be connected at the intended junction at the rear side of the ASP. To achieve an effective exhaustion, a low pressure in the external fume hood should be used. However, even with an external connection you have to install an activated carbon filter.
