1. 15 000 cycles per second ultrasound source into a fluid suspension of the material being treated Typically when ultrasound is applied to a bulk biological sample solution as for the extraction of intracellular constituents from tissue the treatment causes a complex heterogeneous mixture of sub events that vary during the course of a treatment dose In other words the acoustic energy effects may change between various spatial and temporal states during the course of a treatment For example the energy may directly treat a sample the energy may displace the target and shift the target out of the optimal energy zone the energy may result in interference i e a bubble shield that reflects the acoustic energy or the large particles may move to low energy nodes thereby leaving the smaller particles with more dwell time in the high energy nodes In addition the sample viscosity temperature and uniformity may vary during the ultrasonic process resulting in gradients during the process The current low frequency unfocused sonicator type processes are random and non uniform This limits the use of ultrasound in applications where treatment standardization is required In contrast with the Covaris Process focused acoustics are computer generated and delivered to individual samples with the S series systems The mechanical energy imparted on the sample results in a controlled series of compression and rarefaction events The S series in2. 7 For convenient usage find the executable file under c Covaris S Series v2 xx Program and create a shortcut to the desktop Do not drag executable file to the desktop just create shortcut 8 Double click on the shortcut to start SonoLab Single NOTE If the software is being installed on a computer already running a previous version of SonoLAB Single only the SonoLAB installation is required The NI VISA and driver installations will not be necessary Details can be found in the ReadMe file of the install CD Contact Covaris for assistance NOTE Laptop standby and hibernate modes should be avoided while operating the SonoLAB Single software To ensure this from the start menu open Control Panel then Power Options Select a Power Scheme that sets System standby and System hibernate times to Never If standby and hibernate modes remain enabled then the SonoLAB Single software should be closed and the system powered down whenever the system is not in use NOTE SonoLab Single software was not tested with other application software and therefore we recommend that no additional application software is loaded Wireless Network Connections on the Laptop should be disabled to avoid loading of any unwanted software Go to Network Connections in the Control Panel Highlight the Wireless Network Connection and select disable this network device S series User Manual 23 Covaris APPENDIX C
