Insert cups are used for the application of chemically aggressive liquids (e.g. TICKOPUR J 80 U), the removal of chemically aggressive or abrasive soiling or the sonication of sample liquids (indirect sonication). Since nothing must be placed on the bottom of the ultrasonic bath, BANDELIN offers suitable perforated covers / insert strips to hold the insert cups. Another advantage: Several insert cups can be exposed to different liquids simultaneously (e.g. removal of dental cements with STAMMOPUR Z in one insert cup and cleaning with simultaneous chemical disinfection of dental instruments with STAMMOPUR DR 8 in a second insert cup).
