These basic tools are designed to be used with both analog and digital units for a wide variety of general applications. They are available in standard sizes ranging from 3/8" to 1.0."
For use with discontinued models S250D, S450D, and current models SFX250, SFX550, S250A, S450A.
These smaller, high-intensity tips are ideal for processing smaller samples in Eppendorf vials or similar vessels. Available in stepped or tapered designs. Sizes range from 1/8" to 5/16".
Microtips for the SLP Sonifier are available in four sizes to handle volumes up to 100 ml. The microtips are also designed to process samples to the smallest diameter vessels. The 1/8" microtip is already provided with the SLP Sonifiers.
Cup Horns - Standard Intensity
For use with S-450 units only.
These specialized horns permit high intensity sound to be applied to multiple samples without direct horn contact. Units are available in 2.0" and 3.0" diameters.
For use with S-450 units only.
This 1.0" horn is similar to a standard cup horn but utilizes a parabolic reflector to amplify the sound intensity while producing maximum sound density within the sample.
These horns offer the ability to pass a process liquid through an intense energy field within the horn itself. Dual ported horns permit the emulsification of two dissimiliar liquids in controlled, continuous proportions.
This temperature-controlled chamber permits continuous processing of a flowing liquid through a high-intensity ultrasonic field.

3" Diameter Cup Horn for the SLP Sonifier Cell Disruptor is ideal as an indirect method of sonification for open and closed vessels. The cup horn enables sonification of a sample without the horn coming in contact with the solution.
These cabinets have been designed to effectively contain operating noise while providing easy access to process samples. Suitable for standard or inverted horn operation.

Sealed Atmosphere Horns
(No longer available)
These specialty horns have been developed to handle noxious or hazardous samples while isolating them from incidental contact or to contain reactants for metric evaluation.
