No drops are coming out of the Luminase dropper bottle. Is this an indication that it is spoiled?
Drops are not coming out of the Luminase dropper bottle.
In some cases, the nozzle of the Luminase dropper bottle can become plugged. The Luminase in the bottle will generally still be good. One can access this Luminase by removing the nipple from the top of the dropper bottle, and using a micropipette to dispense the Luminase. The chemistry will have the same shelf life in this condition.
