9. Cleaning
The instrument must be cleaned in the following situations to assure correct operation:
if the piston becomes difficult to move
-
after dispensing liquids which form deposits
-
before changing the reagent
-
prior to long term storage
-
should liquid have accumulated in the closure cap
-
prior to sterilization
-
before replacing the valves
-
1. Remember to recover the reagent before cleaning the dispenser.
2. Make sure the dispenser is still properly mounted on the reagent bottle and
there is plenty space in the bottle for the reagent inside the dispenser to be
recovered.
3. Rotate the recovery switch clockwise by 90 degrees to the direction
perpendicular to the discharge tube, and the remaining
reagent inside the dispenser will flow back into the bottle
underneath.
4. Turn off the recovery switch. Carefully remove the
dispenser from the reagent bottle to another empty bottle.
Pull and push the piston for several time to dispense the
remaining reagent from the discharge tube into the reagent
bottle as much as possible.
5.Remove the dispenser from the empty bottle to another
bottle full of distilled water (or other proper wash buffer).
6. Rinse the instrument by dispensing the washing liquid into a
beak again and again.
7. Empty the bottle, flush it and fill it with distilled water.
Repeat step 6 to 7.
8. Empty the instrument.
9. Unscrew the piston seat (1).
10. Carefully pull the piston out of the glass cylinder by pulling on the piston seat
only.
11. Carefully remove sediments at the edge of the glass cylinder with a
screwdriver. Clean piston and cylinder with a bottle brush.
12. Carefully reassemble the instrument in the reverse order. Flush it with distilled
water.
Note:
Insert the piston straight into the cylinder, not at an angle.
9.1. Clean/Replace the valve
1. Follow all cleaning instructions.
2. Remove the filling tube.
3. Unscrew the filling valve using the mounting tool. Remove the valve with its seal.
Make sure the seal does not remain in the valve block.
