- Use your thumb on the piston rod, or the knob on the end of the piston, to move the seal rapidly up and down in the jet to remove most of the air from below the seal.
- Start filling with the piston fully downward near the jet.
- Thumb upwards, or pull ball/piston rod upwards, to set the red line above the 0 graduation - then move the piston down to set the red line exactly on the 0 mark. Remove drops from the Syrette (pipette) tip.
- Dispense with the tip of the diji touching the side of the receptacle close to the fluid surface.
NOTES:
Tighten seal to ensure piston moves only in response to positive thumb pressure. (diagram below)
AIR BUBBLES under the seal or on sides of Syrette will NOT affect volumetric accuracy. Volume dispensed is determined by the distance the piston is moved
TO PREVENT DRIPPING expand and tighten the seal by rotating the flat-sided roller on piston rod immediately above the seal.
TO PRECONDITION glassware when switching from one chemical to another, draw up small amount into diji, invert diji and draw piston fully towards hand-piece, dispose of the fluid to waste.
TO CLEAN, fill and empty diji with tap water then distilled water. For thorough wash, remove Syrette and wash all as glassware. Keep hand-piece and Syrette together to prevent need for adjustments later. Autoclavable - remove Syrette and draw piston fully into hand-piece when autoclaving.
All parts are replaceable without tools.
