System Component Description
Digital Sonifier
This attachment, which is screwed onto the disruptor horn, permits continuous processing of
low-viscosity materials at rates of up to 38 liters per hour. Designed primarily for emulsifying,
dispersing, and homogenizing, the attachment will disrupt most cells, with the exception of the
more difficult species. The materials being treated can be passed through the attachment more
than once to obtain desired results. For cooling, a water jacket with input, output, and overflow
connections is provided.
Rosett Cell
The Rosett Cell, made of borosilicate glass, has a conical shape with three side arms, through
which the solution is driven by pressure produced from vibrations from the ultrasonic horn,
thereby exposing the substance to ultrasonic energy repeatedly during circulation. When the
Rosett Cell is immersed in a cooling bath, the enlarged glass surface area and circulation
through the side arms provide an efficient means of heat exchange.
The Rosett Cell is available in three sizes: 8-25 ml, 25-180 ml, and 35-300 ml.
Flow-Thru Rosett Cell
The Flow-Thru Rosett Cell is equipped with its own water cooling jacket, with intake and out-
put connections for continuous processing and a double chamber for cooling. Normally, ade-
quate cooling can be achieved by connection to the cold water tap or by using a closed circuit
system. An ice/salt water solution will maintain a temperature below 0
°
C. Since the double
chamber is made of glass, the substance can be easily observed during treatment. The Flow-
Thru Rosett Cell is not suited for difficult cells.
