4. Setup

1. Unpacking: Carefully remove the vortex mixer and all accessories from the packaging. Retain packaging for future transport or storage.
2. Placement: Place the unit on a clean, stable, and level laboratory bench away from direct sunlight or heat sources. Ensure adequate ventilation around the device.
3. Accessory Installation: Attach the mixing cup head or any other desired platform/accessory firmly onto the vibrating shaft.
4. Power Connection: Connect the provided power supply to the instrument's power input and then plug it into a grounded electrical outlet.

5. Operation

5.1 Powering On/Off

• To turn the unit ON, flip the rocker switch to the 'ON' position.
• To turn the unit OFF, flip the rocker switch to the 'OFF' position.

5.2 Selecting Operating Mode

The ZX4 offers two operating modes: Sensor Mode and Continuous Mode.

• Sensor Mode: Press the 'SENSOR/CONT.' button until the red 'Sensor Mode' indicator light illuminates. In this mode, the mixer will automatically start vibrating when a test tube is placed onto the mixing cup head and stop when removed.
• Continuous Mode: Press the 'SENSOR/CONT.' button until the red 'Sensor Mode' indicator light is off. In this mode, the mixer will vibrate continuously at the set speed until the unit is turned off or the mode is changed.

5.3 Adjusting Speed

Rotate the blue speed control knob clockwise to increase the mixing speed and counter-clockwise to decrease it. The speed can be adjusted from 0 to 3000 RPM.

5.4 Vortexing Samples

1. Ensure the appropriate mixing accessory is installed.
2. Select either Sensor Mode or Continuous Mode.
3. Set the desired mixing speed using the speed control knob.
4. If in Sensor Mode, gently press the bottom of the test tube onto the mixing cup head. The mixer will start automatically.
5. If in Continuous Mode, the mixer will vibrate constantly. Carefully bring the test tube into contact with the mixing cup head.
6. Mix the sample for the required duration.
7. Remove the test tube. If in Sensor Mode, the mixer will stop automatically.

6. Maintenance

6.1 Cleaning

• Always disconnect the power supply before cleaning.
• Wipe the exterior surfaces of the device with a soft, damp cloth.
