Laboratory Equipment

There are many different types of equipment found in scientific research laboratories. The vortex mixer is a simple yet vital instrument that is a necessity in any lab.

What Is A Vortex Mixer?

A vortex mixer is a device that mixes small amounts of liquid rapidly. Think of it as being similar to a tornado where the air is pulled into a zone causing water droplets to form a funnel cloud and revolve around a straight or curved axis line. The vortex mixer works pretty much the same way in creating its vortex.

How Does A Vortex Mixer Work?

The vortex mixer basically is made up of an electric motor with a vertical drive shaft. This is connected to a rubber cup that is slightly off-center. As the motor runs, the cupped rubber rapidly oscillates in a circular motion. 

When the container of liquid makes contact with the rubber cup, the motion is then transmitted to the liquid inside the container and the vortex is formed. Most vortex mixers have variable speed settings which result in precision temperature control.

What Is The Purpose Of A Vortex Mixer?

The vortex mixer is a key instrument when it comes to scientific research. They are used in biochemical, bioscience, microbiology, and analytical research. The rotational velocity is designed to create a suspension. In microbiology, the purpose of the suspension is to disrupt or suspend cells. 

Features And Benefits Of Using A Vortex Mixer

The vortex mixer is a simple device with simple features. The features basically consist of several speed options and may come with other programmable features such as continuous function or on-demand function.

There are several benefits when it comes to using a vortex mixer. The different speed settings assure that the intended speed is maintained throughout the procedure. Vortex mixers can accommodate anywhere from one vial to a dozen vials where they are being mixed simultaneously. 

The vortex mixer also requires very little space, power, and skill to operate. However, the ultimate benefit is that the vortex mixer ensures a reliable and efficient method of mixing samples.

Top Uses Of A Vortex Mixer

Vortex mixers are more commonly found in bioscience labs and molecular biology procedures. In bioscience labs, they are used to suspend cells. In molecular biology procedures, they are used for incubating cultures since they can create precise temperatures at different speeds.

Different Types Of Vortex Mixers

1. Digital Vortex Mixer

The Digital Vortex Mixer offers a digital display of time and speed and is designed for an accurate continuous function or an on-demand pulsating function. The VM-D is one of the most powerful mixers on the market designed for more aggressive mixing. The speed ranges from 300 rpm to 4,200 rpm so the range is pretty widespread from low velocity mixing to aggressive mixing.

The attachments include the VM-D-FLASK which holds 250 ml, a VM-D-PLATE which is a foam insert and holds a 1 microtiter plate, a VM-D-PLATFORM which is a universal platform, and a VM-D-TUBE that is a foam insert and holds 24 1.5/2.0 ml microtubes.

2. Mini Vortex Mixers

The Mini Vortex Mixers are more compact and portable which allows for vortexing anywhere in the lab. The VM-M is a powerful mixer with a 100 mm x 100 mm footprint and a maximum speed of 4,500 rpm. The suction cup on the bottom of the unit adds stability, minimal vibration, and minimal sound. The base is designed out of die-cast aluminum so it is extremely sturdy, solid, and made to last.

3. Multi-Tube Vortex Mixers

Multi-Tube Vortex Mixers are designed to mix a single or multiple flasks and tubes. The VM-MT features a variable speed along with a  digital display which includes a timer. The speed ranges from 300 to 2,500 rpm so they don’t quite reach the velocity speed of the more simple mixers that hold fewer vials.

The attachments include the VM-MT-7 which is a 7 ml tube foam designed to hold 60 tubes, the VM-MT-15 which is a 15 ml tube foam that securely fits 45 tubes, the VM-MT-50 which is a 50 ml tube foam to house 18 tubes, and the VM-MT-FLASK which is a 250 ml flask foam designed for 6 flasks.

Vortex mixers have been around since the ‘60’s and are still just as essential as they ever were. Scientific research heavily relies on this one simple piece of equipment.
