Remove the Dispense Tubes and Injector Tip Holder
See Figure 2-3 on page 14 for the location of the injector tip holder.
1. Purge the dispense lines of all fluid; see the instructions under on page 37 .
2. Open the door on the front of the reader.
3. Grasp the injector tip holder by the tab and pull it up out of its socket.
4. Using your fingers, remove the thumbscrews securing the light shield to the top of
the reader and slide the shield up the outlets tubes.
5. Slide the injector tip holder through the hole in the top of the reader.
6. Turn each tube’s thumbscrew counterclockwise and gently pull the tube from its
injector tip.
7. On the dispense module, turn each outlet tube’s thumbscrew counterclockwise to
disconnect it from the syringe drive.
Caution! Do not bend the injector tips! A bent tip may not
dispense accurately.
Clean the Dispense Tubes and Injectors
As discussed on page 54 , some reagents can crystallize and clog the tubing and injectors.
Daily flushing and purging can help to prevent this, but more rigorous cleaning may be
necessary if reagent has dried in the tubing or injectors.
To clean the dispense tubes, soak them in hot, soapy water to soften and dissolve any
hardened particles. Flush each tube by holding it vertically under a stream of water.
To clean the injectors:
l
Gently insert the stylus into each injector tip to clear any blockages. (The stylus is
stored in a cylinder affixed to the rear of the dispense module.)
l
Stream water through the pipe to be sure it is clean. If the water does not stream
out, try soaking in hot, soapy water and then reinserting the stylus.
