Vortex Mixer Usage in the Laboratory: Definition, Application, Principal, Operational Procedure

Most of the laboratories have to blend various components carefully and regularly. The manual blending of such components might not provide the preferred result. Thus, laboratories prefer to use different devices such as vortex mixers. 

What Does a Vortex Mixer Mean? 

A vortex mixer is a type of laboratory device that makes a vortex for blending two liquids in tubes of different sizes. The vortexer works by an electrical current, and its speediness is manageable. It is a tiny portable apparatus that is appropriate for blending small capacities of liquid samples in the laboratory. Researchers in bioscience laboratories commonly use vortex mixers. They use these mixers to suspend cells in cell culture and microbiology labs. Biochemical and analytical labs also use vortex mixers to combine assay reagents or an experimental sample with a dilutant. Vortex mixers and centrifuges are both laboratory devices that use centrifugal forces, but they have clear differences in their usages and operations. There are some main differences between a vortex mixer and a centrifuge.

What Are the Parts of a Vortex Mixer? 

 

Main Power:

The electrical current needed to run the vortex mixer comes from turning on the main switch. This switch manages the machine's power.

Motor:

The motor is the core of the vortex mixer. It rotates in a circular motion and sits immediately below the cup head. This motor creates a vortex effect in the liquid to ensure proper sample homogenization.

Speed Control:

The speed control knob is on the front panel of the machine. Turning this knob adjusts the speed of the rotation.

Mixer Operation:

The machine has an embedded control unit that allows the user to program the mixer's operation.

Cup Head:

The cup heads come in various sizes to enable rapid mixing. These heads are interchangeable, allowing users to blend a range of tube sizes. The tube sits on the cup head to produce the vortex effect.

How Does a Vortex Mixer Operate; Step by Step Procedure

1. Unpack the apparatus and remove it from its packaging. 
2. Place the device on a smooth and level surface.
3. Connect the power cable at the back of the apparatus to a power source. Place the rubber head on the apparatus shaft and, by pressing the power button, the apparatus will be ready to use.
4. Now, by turning the volume control next to the power button, you can set the apparatus within a range of different mixing intensities. The more the volume control is turned towards Max, the more intense the mixing will be.
5. Place the sample in the Falcon tube in the designated head on the apparatus. Make sure that Falcon tubes used for mixing are firmly held to prevent any potential hazards.

Safety Protections When Working with a Vortex Mixer: 

Ensuring safety is crucial when operating a vortex mixer. Following these important safety protections can protect individuals and maintain a safe working environment: 

1-Secure the Shaking Head

Always make sure the shaking head is firmly in place before operating the vortex mixer. Verify that the shaking head is securely attached to prevent any accidents or dislodging during use.

2-Wear Eye Protection

Use impact-resistant eye protection, such as protection goggles or glasses, when running the vortex mixer. This safeguards your eyes from potential splashes or spills that may occur during the mixing process.

3-Avoid Flammable and Hazardous Substances

Refrain from mixing or using solvents, flammables, or other dangerous substances near or on the vortex mixer. Doing so can heighten the risk of fire or chemical reactions. Keep a safe distance between the mixer and any flammable or hazardous materials.

4-Use Proper Containment Vessels

When mixing potentially dangerous samples, place them in appropriate containment vessels designed to safely hold and contain the specific substances. This prevents leaks, spills, or exposure to harmful materials.

5-Wear Personal Protective Equipment (PPE)

Always use proper hand and eye protection while operating the vortex mixer. Gloves can shield your hands from hazards or chemical exposure, while eye protection safeguards against splashes or flying particles.

6-Refrain from Using Flammable Substances

Avoid using flammable substances while running the vortex mixer, as they pose a fire risk. Follow proper storage and handling procedures for flammable substances in your laboratory.

7-Use Sealed Containers for Hazardous Substances

While shaking dangerous materials, make sure they are included in closed vessels or containers. These assist in preventing any unplanned release or exposure to detrimental fumes or substances. 

8-Securely Attach the Cup Head

Pay attention before utilizing the vortex mixer, try to check that the cup head is firmly attached. Because this helps to prevent any separation or movement while working with the apparatus. 

9-Maintain and Repair the Vortex Mixer

Frequently try to check the vortex mixer to make sure it is working appropriately and safely. Follow producer guidelines for preservation procedures and schedule any essential repairs on time. Do not use defective equipment until it has been properly serviced or repaired by qualified personnel.

Various Applications of Vortex Mixers in the Laboratory Industry: 

A Vortex mixer is used in wide different fields, here are some applications of this apparatus:
