1. Introduction
The HFBTE Multi-Tube Vortexer is a microprocessor-controlled, pulsed vortex mixer designed for scientific laboratory applications. It is engineered for experiments requiring high mixing intensity and is capable of processing up to 50 samples simultaneously, significantly saving time and effort. This instrument is primarily utilized in fields such as food safety, residue and food additive testing, drug analysis, and drug development. Its automated mixing capabilities enhance the reproducibility of experimental methods and improve sample recovery rates.
The unique knob operation mode ensures ease of use, and the ability to change different tube fixing sponges allows for mixing and incubation of various common tube types.
2. Key Features

4. Setup
- Unpacking: Carefully remove the Multi-Tube Vortexer from its packaging. Inspect the unit for any signs of damage during transit.
- Placement: Place the vortexer on a stable, level surface in a laboratory environment. Ensure adequate clearance around the unit for ventilation and operation.
- Assemble Fittings: Insert the sponge test tube rack into the lower tray. Place your test tubes into the rack. Position the upper tray sponge pad over the test tubes.
- Secure the Upper Cover: Press the upper cover tightly down onto the support rods and fix it in place using the adjustment knobs on the sides. Ensure the test tubes are securely held between the upper and lower sponge pads.
- Power Connection: Connect the power cord to the power socket located on the back of the instrument. Plug the other end into a suitable AC power outlet (AC110~220V, 50/60Hz).
- Power On: Flip the power switch to the 'ON' position. The LED displays on the control panel should illuminate.

5. Operation
The Multi-Tube Vortexer offers several operation modes: Continuous, Inching (Short Mix), and Pulse (Programmed).
5.1 Continuous Operation Mode
- Ensure the unit is powered on and test tubes are securely loaded.
- Use the speed control knob to set the desired RPM (100-2500 RPM). The speed will be displayed on the left LED screen.
- Use the time setting knob to set the desired operation duration (1 min to 99h 59min). The time will be displayed on the right LED screen.
- Press the "Start/Stop" key to begin continuous mixing. The unit will operate for the set duration and automatically stop.
- To stop operation manually before the set time, press the "Start/Stop" key again.
5.2 Inching (Short Mix) Mode
This mode is suitable for quick, short bursts of mixing.
- Ensure the unit is powered on and test tubes are securely loaded.
- Press and hold the "Inching key" (Short key) to activate the short mix function. The vortexer will operate only while the key is pressed.
- Release the "Inching key" to stop mixing.
5.3 Pulse (Programmed) Mode
The pulse mode allows for setting up to 10 program segments for more complex mixing protocols.
- Refer to the detailed programming instructions in the full user manual for setting specific pulse parameters (speed, duration, and number of cycles for each segment).
- Once programmed, press the "Start/Stop" key to initiate the programmed pulse sequence.

6. Maintenance
- Cleaning: Regularly wipe the exterior surfaces of the vortexer with a soft, damp cloth. For spills, use a mild detergent solution. Ensure the unit is unplugged before cleaning. Avoid using abrasive cleaners or solvents that could damage the surface.
- Sponge Racks: The foam racks can be removed and cleaned with water and mild soap. Ensure they are completely dry before re-inserting them into the unit.
- Motor: The brushless DC motor is designed for long service life and is maintenance-free. No lubrication or internal cleaning is required.
- Storage: When not in use for extended periods, store the vortexer in a clean, dry environment away from direct sunlight and extreme temperatures.
- Fuse Replacement: The instrument is equipped with fuses for protection. If the unit fails to power on, check the fuse located near the power socket. Replace with a fuse of the same rating if necessary. (The product details mention 3 fuses are included).
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Unit does not power on. | No power supply; Power cord loose; Blown fuse. | Check power outlet; Ensure power cord is securely connected; Replace fuse (refer to Maintenance section). |
| Vortexer not mixing or shaking weakly. | Incorrect speed setting; Overload; Test tubes not properly secured. | Adjust speed setting; Reduce sample load; Ensure upper cover is tightly fixed and test tubes are snug in the rack. |
