Bransonic accessories are designed to maximize the effectiveness of your Bransonic baths. It is important that parts do not rest on the bottom of the bath, as it can inhibit the ultrasonic activity and possibly damage the unit. A variety of perforated trays, mesh baskets, beakers, and support racks give you the option of direct or indirect cleaning. All five models come with covers to allow the cleaning bath to heat up more quickly. Direct Cleaning Method • Suspends parts using a perforated tray, mesh basket, or a support rack. • Permits sound waves to penetrate directly to the parts. Indirect Cleaning Method • Suspends parts using a solid tray, or beakers with a beaker cover. • Ideal for cleaning small parts. • Discarded soil cleans easily from a beaker or solid tray. • Indirect method is ideal for sample preparation.
