One of decanter centrifuge professionals tips is in the process of high speed, the movement caused by the centrifugal force making the solid material suspended in the liquid precipitation, larger objects with big weight or volume of the suspension fluid will move towards the direction of the largest turn radius, and the smaller objects with small weight or volume will deposit in the place of the smallest turn radius.
One of decanter centrifuge professionals tips is the above we mentioned the concept of the centrifugal force.Decanter centrifuge is a machine to generate centrifugal force, centrifugal force is related to the rotor radius, speed and quality of samples: namely F=Rmω2 (F: centrifugal force, R: radius, m: sample quality, to: speed), centrifugal force is one of the most important parameters to measure decanter centrifuge, is also one of the difference of the decanter centrifuge class standard, when the decanter centrifuge leave the factory it will be given the largest centrifugal force.
As we all know, the radius of the rotor and the sample quality is invariable during operation, we can only control rotate speed, so we tend to use speed to describe a decanter centrifuge.Such as: high-speed decanter centrifuge, high-speed decanter centrifuge.
One of decanter centrifuge professionals tips is there are many different kinds of decanter centrifuges, we are used to classify it from the following several aspects: according to the size of the rotational speed it can be divided into: low speed decanter centrifuge, high-speed, super high-speed centrifuge; according to the requirements of the temperature it can be divided into: ordinary decanter centrifuge and refrigerated decanter centrifuge; according to the different of the rotor it can be divided into: horizontal decanter centrifuge and angle centrifuge; according to the size of the centrifuge it can also be divided into: floor centrifuges, centrifuge table centrifuge, handheld decanter centrifuge; according to the grade of the centrifuge it can also be divided into ordinary centrifuge and precision decanter centrifuge. Ordinary centrifuge has not many function, it is not accurate in terms of speed and capacity, such as: an ordinary decanter centrifuge maximum speed is 5000 r/min, but the actual speed but can't reach 5000 r/min.The decanter centrifuge is only suitable for ordinary centrifugal work, such as: separation of serum, concentrated urine.
One of decanter centrifuge professionals tips is precision decanter centrifuge has many functions, rotating speed and capacity are accurate, it is suitable for some experiments that needs higher requirements of decanter centrifuge , such as: the PCR separation experiment, blood component (more for blood stations), etc.When choosing ordinary decanter centrifuge, according to the size of the workload, we should choose mainly from two aspects of speed and capacity.
Today we will talk about the problem we should pay attention to when choose and buy decanter centrifuges : (1) speed: according to maximum speed decanter centrifuge it can be divided into low speed decanter centrifuge (< 1 0000 RPM/min), high-speed decanter centrifuge (1 a 30000 RPM to 0000 RPM/min/min), ultra high speed decanter centrifuge (> 30000 RPM/min), each decanter centrifuge has rated maximum speed, maximum speed refers to the speed under the condition of no-load speed, but the maximum speed differs according to the type of the rotor and the size of the sample quality.
(2) temperature: some samples (such as protein, cells, etc.) under the environment of high temperature it will damage, this needs us to choose refrigerated decanter centrifuge, refrigerated decanter centrifuge has rated temperature range.ng.
