The Vanning Plaque Laboratory Pan was originally designed by Professor Richards and has found wide acceptance for panning small amounts of fine material. The surface is white, with baked enamel finish. This unit is especially useful for laboratory work in studying the products from concentration tests. It is available in one size only and shipping weight is one pound.
This pan is an extremely useful item to have about your mill for studying the various mill products in order to observe mesh at which minerals are freed, amount of sliming, efficiency of operation of various units, and other factors which may be approximately determined by visual examination.
The Laboratory Hand Gold Pan is a useful item of equipment for laboratories which test alluvial materials for gravity concentration. This pan makes possible rapid preliminary visual inspections to determine the existence of values. Pans can be furnished in either the all steel standard pan or the copper-bottomed pan. The latter is made of steel with a copper bottom and forms an excellent amalgamating unit when coated with mercury.

Batea Hand Gold Pan
The Batea Hand Gold Pan, patterned after the Latin America Batea, is so simple to operate that anyone can easily use it to recover gold without previous experience. The Batea Gold Pan is both a gravel washing and concentrating device. It is shallow, disk shaped, and has a turned up rim which catches and holds the gold and black sands, making it very difficult to lose the values while washing. The small depression in the center is useful in finally separating the gold and black sands, and gold concentrates can be easily removed through the hole in the rim. Operating instructions are furnished with each Batea Hand Gold Pan. The diameter of this pan is 19½”, weight 4 lbs.
