The following editor will briefly introduce the operation process of the sterile homogenizer and some precautions. Welcome to come to consult and buy.

Operating procedures:

1. Unpack the instrument, remove the box, remove the CX-20 sterile homogenizer, and move it to a place close to the power supply and place it on the work surface stably.

2. Connect the power cord to the socket at the back of the machine and plug it into the external output power socket, turn on the power switch, the LCD screen will display the factory settings, and the homogenizer will automatically be in the standby state.

3. Check and confirm the groove on the lower edge of the door of the aseptic homogenizer when using it. Other homogenizers may not have them. Generally, there are good ones. They can be used for fixing. Move the door handle and open the door to the maximum. Put the homogenizing bag containing the sample and solvent into the homogenizing box, and the lower edge of the homogenizing bag is basically parallel to the lower plane of the hammer plate (when the sample is less than 100 ml, the lower edge of the homogenizing bag should preferably be higher than the stainless steel hammer). Press the lower plane of the plate 1-2 cm to prevent the homogeneous bag from breaking), the edge of the homogeneous bag is exposed to the door cover, the edge of the homogeneous bag should not be wrinkled, and then turn the door switch, after hearing a "drip" sound (this When the LCD screen should display "close door"), indicating that the door has been closed. At this time, the door and the upper rail are squeezed to clamp the homogenizing bag to seal it.

4. Select the speed and timing on the panel according to the need to homogenize the sample. Each time the key is pressed, there will be a beep sound. Press the "Settings" button, at this time, the LCD screen M1 and the number of tap times flash, indicating that it is in the setting state, press the setting button continuously, M1 tap times - M1 tap minutes - M1 tap seconds - M2 tap times - M2 beat minutes - M2 beat seconds - M3 beat times - M3 beat minutes - M3 beat seconds - exit. When pressing the "Set" button to the parameter that needs to be adjusted, press the increase or decrease button, the parameter will be adjusted accordingly, long press for more than 1S, the number will increase or decrease continuously, if you want to exit after setting M1, you can Directly "OK/Reset" key to exit. After the setting is completed, press the "mode/cycle" key, M1-M2-M3-cycle-M1 switch. After adjusting the required parameters, press the ON/OFF button, the LCD will work, the machine will run according to the displayed beat times and time, and the running time will be accumulated in seconds. When the set time is reached, there will be a "beep" sound, the LCD display will pause, and the machine will stop working. Press the start/stop button again to run again. If in the cycle mode, the LCD will automatically display the parameters of M2 after the "beep" sound after running the time of M1, and run the parameters of M2, and then run the parameters of M3, and the long sound of "di---", the display pauses, The machine stopped working. During the running process, there is a door opening action, and the LCD displays the door opening and enters the pause state. After closing the door, you need to press the "Open/Stop" key again to start working. In the pause state, press and hold the "OK/Reset" button for more than 1S, the "Di---" long sound, and the running time will be "returned to 0".

5. Open the door of the homogenizer with the right hand, hold the upper edge of the homogenizer bag with the left hand when taking out the homogenizer bag, and finish the work once. If the sample is contaminated, use a special tool to extract the homogeneous bag. The bag should be a sterile bag, otherwise the sample will be contaminated.

Precautions:

(1) The power plug must be plugged in firmly. Looseness may affect the computer controller and cause a crash. If the crash occurs, please turn off the power switch on the rear side, and restart it after 3 minutes of shutdown.

(2) Please do not open the door of the homogenizer at will when the hammer plate is working to avoid overflow of the sample liquid. Should press the "ON/OFF" key, the device will automatically stop running. When the door is closed, press the "Open/Stop" button again, and the device will automatically complete the rest of the work.

(3) If the instrument is not used for a long time, the power should be cut off and the plug should be unplugged.

(4) The bottom of the homogenizer door is designed to be empty in order to prevent accidental rupture of the homogenizer bag and facilitate cleaning of spills. The bottom of the door is designed to be empty, and a water-receiving tray can be placed. Therefore, when the instrument is running, please do not insert your hand from the bottom to avoid strangling your fingers. .

(5) Before the machine is running, please check whether there are foreign objects in the homogenizing box to avoid malfunction and damage to the homogenizing bag during operation.

(6) Hard lumps, bone-like and ice-like substances should not be used, so as not to damage the homogeneous bag.

(7) The storage of the instrument and the homogenizing bag should avoid direct sunlight, especially the homogenizing bag should be stored in a place without sunlight or avoiding ultraviolet radiation to avoid aging.

(8) When the amount is small, when the speed needs to be increased, when the fiber of the homogeneous material is tough, the back knob can be used to adjust the distance between the slap plate and the visual window to achieve a better homogeneous effect.
