Heathrow Scientific's Non-Sterile Pill Counting Trays are for counting pills that are round-shaped. These trays are extremely easy to use, simply form the pills into even rows, count the number of rows and look up the total on the scale. Once this is complete, you'll be able to easily pour the pills into a bottle. These trays are intended to be single-use (disposable). Each tray comes with a curved polypropylene spatula for additional sorting convenience. The trays are made out of polystyrene and come in the color white. Sold in packs of 10.
