Trident reagent needle guide set of 3
Trident reagent needle guide set of 3 ensures that the maximum of reagent is used
Unscrew the caps from the reagent bottle and insert the ‘funnel’ into the bottle.
Then insert the needle through the center hole of the guide and screw on the bottle cap.
This prevents the needle from tipping and staying in place when the tray is pushed back into place.
This prevents the needle from drawing in air and using the maximum reagent from the bottle.
