Frequently asked questions
What is a vortex mixer and how does it work?
A vortex mixer is a laboratory instrument used to rapidly mix small vials of liquid. It works by creating a circular, high-speed motion that agitates the contents through orbital movement, ensuring homogenous mixing without manual shaking.
Why should I choose an Ohaus vortex mixer over other brands?
Ohaus vortex mixers are known for their reliability, precision speed control, and ergonomic design. They offer robust construction, low-noise operation, and compatibility with a wide range of tube sizes, making them ideal for demanding lab environments.
What’s the difference between a vortex mixer and a multi vortexer?
A standard vortex mixer is designed to mix one tube at a time, typically via touch activation. A multi vortexer, on the other hand, can mix multiple tubes simultaneously, increasing throughput and efficiency in high-volume labs.
Are Ohaus vortex instruments compatible with different tube sizes and accessories?
Yes, Ohaus vortex instruments are designed to be versatile. They support various platforms and tube holders, allowing seamless integration with microtubes, test tubes, vials, and even microplates, depending on the model.
What are the key applications of vortex mixers in a laboratory setting?
Vortex mixers are used in molecular biology, microbiology, clinical diagnostics, and analytical chemistry. Common applications include mixing reagents, resuspending pellets, and preparing samples for PCR, electrophoresis, or cell culture work.
Can a vortex mixer be used for temperature-sensitive samples?
Yes, while vortex mixers do not actively heat or cool samples, their quick and efficient mixing minimizes prolonged exposure to ambient conditions, making them suitable for temperature-sensitive processes when used appropriately.
How do I maintain a vortex instrument to ensure long-term performance?
Regularly inspect the unit for wear, keep the platform clean, and avoid overloading the instrument. Follow Ohaus’s maintenance guidelines for calibration and safety checks to ensure optimal operation and extended equipment lifespan.
Do Ohaus multi vortexers offer digital control and programmability?
Yes, select Ohaus multi vortexer models feature digital displays, programmable speed and time settings, and continuous or pulse operation modes—ideal for protocol standardization and reproducibility in regulated environments.
