Seedburo's hand testing screens are a must for anyone who buys, cleans, or grades seed or grain. They are made of selected straight grained wood with nesting frames. These screens can be stacked together with a blank bottom pan to make several separations at one time.

A generous assortment of sizes will enable you to experiment with various separations and select the correct screens for your larger cleaning or sizing operations. Our hand test screens are an excellent choice for experimental or laboratory use when only small samples are available. Made in USA.

Ship wt: 3 lb. each

Please specify the screen perforation sizes on your order, they can be added in the comments field. Bottom pans are sold separately.

Note: Screens are custom made for order - non-returnable
