Horns are designed to allow chilled water to circulate through the Cup Horn to
prevent heating of the solution as a result of the ultrasonic activity. The Cup Horn
is available with a water cooling device which allows water to flow through the
cup, keeping the material cool.
!
The bottom of the test tubes should not be in contact with the surface of
the ultrasonic horn, which could cause breakage.
C.3 Flow-thru Horn
Designed for pharmaceutical research, the flow-thru horn has two inputs or ori-
fices at the non-vibrating, nodal point of the horn. A pre-mixed substance is fed
through one of the units while the horn is ultrasonically activated. Because two
inputs are available, two different types of material can be treated simultaneously,
for mixing or emulsifying. The processed solution exits at the tip of the horn. The
horn may be used as a continuous-flow device to collect the solution in one large
vessel. Or, by using a special switching, an instantaneous ON/OFF action permits
multiple tubes or vials to be filled.
C.4 Rosette Cell
The Rosette Cell, made of borosilicate glass, has a conical shape with three side
arms, through which the solution is driven by the ultrasonic horn, thereby expos-
ing the substance to ultrasonic energy repeatedly during circulation. When the
Rosette Cell is immersed in a cooling bath, the enlarged glass surface area, plus
circulation through the side arms, provide an efficient means of heat exchange.
The Cell is available in three sizes: 35-300 ml, 25-180 ml, and
8-25 ml.
