Ohaus multi-tube vortex oscillator for olive oil analysis program - proper mixing of two-phase liquid system

Today, Xiaobian takes you to the case of the application of the Ohaus multi-tube vortex oscillator at the Department of Biopharmacy and the Department of Natural Product Chemistry at the University of Athens.

Olive oil is a natural oil extracted from the fruits of olive trees. The health benefits of olive oil are well known, but scientific research has revealed and validated the potential of extra virgin olive oil for the prevention and treatment of many chronic diseases. The mystery lies in the amount of a compound called polyphenols, which contain a lot of polyphenols. A few years ago, the European Union enacted a health labeling regulation that stipulates that olive oil containing a certain amount of polyphenols can indicate healthy ingredients on the label. This regulation has redefined the classification of olive oil products - the transformation of the olive oil industry has just begun, Ohaus is involved!

Researchers at the Laboratory of Natural Product Pharmacy and Chemistry at the University of Athens are well aware that olive oil can improve our health and lives. Professor Magiatis Prokopios and his team from the University of Athens are dedicated to studying the health benefits of olives and olive oil.

The university's laboratories analyze olive oil produced in many parts of the world and provide certification for health claims. They serve olive oil producers who are interested in health properties. Not only that, but the team also provides training for manufacturers to study the health and therapeutic properties of all olive products, with the ultimate goal of increasing the economic value of their products. After years of scientific research, the university's laboratory has developed an olive oil analysis program that includes a liquid-liquid extraction step.

A very critical step in the analysis of olive oil is the vigorous mixing of the two liquid components to form a two-phase system. Researchers in the lab are looking for a device that can meet this particular need. They visited the Chem 2017 Expo and met the Ohaus vortex oscillator. After demonstrating the capabilities of the vortex oscillator and testing it in the real world, they are convinced that the Ohaus vortex oscillator is well suited for their workflow.

The multi-tube vortex oscillator from Ohaus is in full compliance with their needs, and now in the university's laboratory, the Ohaus multi-tube vortex oscillator is used whenever liquid-liquid extraction is performed.

“When a typical vortex mixer or rotary mixer is used, the two-phase liquid system cannot be properly mixed. The Ohaus multi-tube vortex oscillator is a high-intensity mixer that almost doubles the two-phase liquid system. Mixture. By using the Ohaus multi-tube vortex oscillator, we automate the daily mixing process."

“From October to February of the following year, we will analyze about 2000 samples during the harvest season of olive oil. Analytical experiments are usually performed on ten sets of samples. Ohaus multi-tube vortex oscillator is used for mixing in 50 A 45 ml two-phase liquid system in a milliliter tube. We usually mix 5-9 samples simultaneously."

——Annia Tsolakou, Researcher

The Ohaus multi-tube vortex oscillator has been well received by laboratory researchers for shortening the analysis time of olive oil. Strong mixing at a horizontal position of 2400 rpm is very effective compared to previous mixing methods. By using a one-minute timer, the trouble of needing an alarm or a timer when mixing steps is eliminated.

Annia Tsolakou concludes: “Overall, no matter how many samples we analyze at one time, or how many times we use the device every day, we get the same standardized results.”

1. The digital display model is equipped with a touchpad controller for easy input settings and a separate LED display for speed/time. The timer can be displayed when running time or programming, when the time is zero, it will be turned off.

2. Digital display control model with programmable function, can adjust pulse pause time in 1s-59s, the shortest intermittent time is 1s. And the pulse function produces a more powerful blending that enhances the vortex oscillating effect.

3. The analog control model is also equipped with a microprocessor controller that provides a consistent and uniform oscillation effect. The user can adjust the speed and time separately with the two knobs labeled 1-10.
