Dynamica Centrifuge – Keep Your Lab Quiet

March 16, 2022 No Comments

Dynamica centrifuge

A quiet centrifuge is very important to most lab users.

Every sound has a decibel level associated with it. If an item is 52 dB(A), then it has a sound similar in intensity to an electric fan, hair dryer, a running refrigerator and a quiet street.

Even at highest speed spinning, the noise level measured is within 52 dB(A). 

Watch the video that introduce more features of Dynamica centrifuges.

Why do we need cooling during centrifugation?

February 21, 2022 No Comments

Some of our readers have doubts after reading the last post. Why there is such a big difference of -20°C on the chamber wall while only 4°C on the sampling position? This is because, during centrifugation, the spinning of the rotor will create some gaseous friction with the air in the chamber. Imagine the rotor is spinning at a very high speed in a centrifuge and this will then generate a lot of heat. This phenomenon explains the differences in chamber and sample tube temperature.

Why refrigerated centrifuge will need -20°C?

February 17, 2022 No Comments

As you are working on your biological samples, you will possibly need a centrifuge with -20°C. Have you ever doubted why the temperature would need to be so low? At negative temperatures, ice crystals will be building up and will denature the cells/organelles. Besides, you normally set the running temperature at 4°C instead of -20°C. Although the specification of the centrifuge is -20°C, this only means the chamber temperature. Your setting of 4°C is meaning the actual temperature on the sample position. This is your sample temperature during centrifugation.

What is a centrifugal force?

What is a centrifugal force?

Centrifugal force is the outward force generated when an object is being rotated. This phenomenon is used on separating substances in a centrifuge. Substances, like blood cells, organelles or DNA, are separated by their density. The higher the density, the higher the centrifugal force it is experiencing and hence being pushed to the bottom of the tube. The less the density, the upper will be the final position.

Dynamica provides you with a variety of selections for benchtop centrifuges.

Daily Maintenance of Rotor

December 9, 2021 No Comments

This week, we will talk about the rotor chamber. A lot of users will just leave the rotor inside the chamber after use. A long period of time later, the rotor might no longer able to be detached from the centrifuge due to corrosion. This will make overhaul of centrifuge impossible. To prevent this, please remove the rotor from the chamber after use. If a rotor cover is provided, detach the rotor cover from the rotor to dry the inside of the tube holes.

First Installation Experience

December 9, 2021 No Comments

Gentlemen, I know you guys are always there for support. Thanks for the end user and our service engineer. The installation of our new Dynamica Centrifuge Velocity 14R Pro could not be easier, even with its’ tens of kilogram weight. This unit is used to separate protein. The user has few standard procedures so he uses the program function and call it up when need to use that specific procedure.
