DragonLab 0.5-10 uL TopPette 8-Multi Channel Adjustable Pipettor
Here is something you probably wont find in a movie prop closet. The multi channel is used to fill 96 well plates with the same reagent in each well at a much more efficient rate of production.
These are quite expensive and even the Dragon Lab (cheapest brand) is around $500. But we have this worthless left over retired from our DNA lab multi channel pipettor that you can use as a prop. It is fully functional ad you can get 4K or 8K closes ups of it working for great b-roll. We also have well plates, thermocyclers and the rest of the lab supplies and equipment you need to base your movie in a science lab.
