WIG-L-BUG WONDER ELECTRIC MORTAR

END MIXING-GRINDING DRUDGERY Using Plastic, Metal or Agate Vials the Wig-L-Bug will become indispensable to you as it has already in hundreds of laboratories in this country and dozens of countries abroad. Use plastic vials for mixing powders or prepar­ ing mulls with mineral oil. For grinding hard materials use the hardened tool steel or agate vial. With these you can obtain 200 mesh materials in 2-3 minutes.

For preparing KBr pellets use stainless steel or agate vials. Invaluable in the fields of X-Ray Diffraction, Emission Spectrographic Analysis, X-Ray Spectroscopy, Infra-Red Spectroscopy, Metallurgy, Geology, Oil Re­ search, Aluminum Manufacture, Chemical, Paint and Color Analysis, Ceramics, Foods, Agriculture.
