Yes. Upon request we can send you the CS studio6 software before purchase.   CS studio6- for experiment run and control    CS Analysis- Data anaylsis     Click "into demo mode" and then you can click and run any experiment through a channel. After you choose an experiment to run, you can click "Browse" to locate the storage path of data files which will be automatically saved during experiment. We want to show the layout of multichannel potentiostat, so there are 2 channels for demo model. For single channel potentiostat, it will directly show "Experiments" and then you can choose a method to run. CS Analysis is for data analysis. You can drag the raw data files directly into CS Analysis, and do the fitting, equivalent circuit etc. Our data files can be opened directly by computer's Notapad, and can also directly drag into Excel or Origin for graping.  

    Dummy cell is a simulation cell. It’s used to check whether the potentiostat is normal. When you receive a potentiostat, you can use it to ensure the potentiostat is well-functional. During tests if you find data abnormal or something wrong, you can also use it to check whether it’s caused by your testing system, or by the malfunctioning of the instrument.   1. Firstly, please connect the potentiostat with dummy cell by the electrode cable, and power on the instrument. If there is a white Sense(SEN) cable, you should always connect it with the green WE together. Cable connection is as follows:   2. Open the software, click “Setup” - “Restore Defaults”. Select “Potentiostatic (i-t)” in the “Experiments”. Pay attention to the OCP, and it’s should be 0. Apply 1.1V vs. RE, choose a location to save the data file by “Browse”, then click “OK”. After it runs, please check the displayed potential /current value. If it’s 1.1V and 1mA respectively, it means the test goes normally, indicating the instrument’s potential output is accurate and normal.   3. Similarly, run “Galvanostatic (E-t)”. The OCP should also be 0. Apply 1mA. Please check the displayed current and potential. If it’s 1mA and 1.1V, it means the test runs normally, and the current output is accurate and normal. 4. Run EIS to click Experiments - Impedance - Potentiostatic EIS (Nyquist, Bode). Keep the parameters setting as default and click OK to run EIS. If the instrument is well-functioning, the result should be as follows, presenting a standard semicircle.

CS905 is non-aqeous Ag/Ag+ electrode. It's used for organic solution environment. The usual filled solution is AgNO3 and AgClO4 iwth concentration of 0.01mol/L~0.1mol/L.

(1) Add 1~1.5g agar powder,10g KCl and 30ml instilled water into a beaker. (2) Heat the beaker on the asbestos gauze to 80℃. During the heating, please stir the solution with a glass rod to dissolve all the powder and get rid of buddles in the solution. (3) Stop the heating, and immerse the tip of luggin capillary into the agar solution, and quickly suck some agar solution into the luggin capillary with the rubber suction bulb (please don’t let air in during this process). Then pour some agar solution from the upper port of the luggin capillary till middle of the thick part. Before the agar gets cold, insert the SCE into the agar. When the agar gets cold, add some saturated KCl solution.  

1. The purpose of polishing As the redox reactions are repeatedly conducted, the products during the reaction will adhere to the surface of the electrode and gradually slow down the electron transfer, which enlarges the potential difference between the oxidation and reduction peak. The purpose of polishing is to remove the redox products adsorbed on the surface of the working electrode, and increase the electron transfer rate to normal. 2. Polishing steps Put a polishing cloth on a glass pad, and give a few drops of polishing liquid on the cloth. The working electrode should be vertically placed on the cloth, and then polish it by drawing “O” or “8” shape. After polishing, wash the electrode surface with distilled water. Note: We provide Alpha alumina powders of three diameters: 1μm/0.3μm / 0.05μm. Use the 1μm firstly and then the smaller ones in order. The method is applicable to the polishing of glass carbon electrode, gold electrode, platinum electrode and silver electrode etc. CS942 Electrorde polishing kit
