Parts Diagram Converter Size Continuous Converter/Probe Adapter Force Spring Bracket Stop Collar Latch Probe Tube Counter Cooler Hand Crank Platform Thumbscrew The continuous force spring helps support the weight of the platform and enables it to move up and down the rod smoothly, either using the latch or the hand crank. The stop collar is used to set the highest point on the rod that the platform can be set.
EpiShear™ Cooled Sonication Platform During shipment of the EpiShear Cooled Sonication platform, the probe chimney, tube cooler, alignment tool and hex wrenches are placed inside of the sound enclosure. Carefully remove each item and perform a visual inspection to detect any damage that may have occurred during ship- ment.
B. Placement of the Converter/Probe To ensure sample-to-sample consistency, the platform has a bracket secured near the top of the rod that holds the sonicator converter/probe. This bracket enables you to fix the placement of the probe tip. Depending on the probe to be used, you may need to adjust where the converter bracket is located vertically on the rod.
C. Calibration of the Platform Counter The counter on the platform needs to be set to an appropriate “zero” point to enable you to return the platform to the same height consistently once you have determined the appropriate height for your purposes.

The crank is then turned to slowly raise the stand up the rod. When the probe begins to enter the Alignment Tool, you may need to adjust the position of the stand so that the probe is centered in the tool. Simply loosen the two thumb screws underneath the stand, use one hand to move the stand forward/backward and left/right until the probe is centered, then re-tighten the thumbscrews.
Using the Cooled Sonication Platform Benchtop Tube Coolers The Benchtop Tube Coolers can keep the temperature of a sample at or below 4°C for up to 2 hours of sonication if the cooler has been placed in a -20°C freezer overnight. If a large amount of time will pass between each sonication, return the cooler be to a -20°C freezer between samples.
Appendix Section A. Attaching the Alternate Spring Bracket The alternate spring bracket was provided in case you need to remove the converter/probe bracket from the top of the rod, which you would need to do if your converter/probe is too large to be held by the bracket.
