Alconox® Powdered Detergent This is a heavy duty, concentrated detergent, developed especially for laboratory use, but for which there are many other applications outside the laboratory, that can be used either manually or in conjunction with ultrasonic cleaning. The product has been especially formulated to be "free rinsing" (e.g. easily rinsed off with running tap or distilled water) with virtually no redeposition of removed (and unwanted) materials, all of which translates to virtually a complete absence of any residues.
