Micro centrifuge is a compact type of centrifuge ideal for separating small liquid samples at high speed (usually more than 6,000 rpm). Most micro centrifuge have available PCR strips rotor, adapters for 0.2 ml PCR tubes, and microhematocrit rotor.
Tabletop centrifuge is sometimes referred to as benchtop centrifuge. It is a larger type of centrifuge ideal for separating larger liquid samples at high speed (usually more than 4,000 rpm). While micro centrifuges run liquid samples using fixed-angle rotor only, most tabletop centrifuge have another type of rotor called swing-bucket. This type of rotor can spin samples up to 90° angle at lower speed. Tabletop centrifuge is commonly used in running various sample tubes at once.

A centrifuge is a laboratory equipment used for the separation of heterogeneous mixtures or samples.
Centrifugation process can be employed to separate particles or macromolecules like cells, sub-cellular components, proteins, and nucleic acids. The particles are separated from a solution according to their size, shape, density, the viscosity of the medium, and rotor speed. Various separation technique can be done using a laboratory centrifuge. Basic applications include sample pelleting, sample separation, sedimentation and preparation, and blood/urine testing.
Centrifuge work by spinning the samples loaded in a rotor at high speed. It undergoes a centrifugation process which involves the use of centrifugal force for the separation of particles or macromolecules.
Centrifugal foce is the apparent force used in centrifuge that draws a rotating body away from the center of rotation. The substance within the solution will be deposited to the bottom of the vessel thru the action of this force.
Swing-out/ swing-bucket, fixed-angle, microtiter plate rotor, PCR strip rotor, hematocrit rotor
No. Rotors have different maximum rcf/rpm. The fixed-angle rotors' maximum speed is 15000 rpm /21380 x g (for MCV & MCR), 15000 rpm/21382 x g (for TCV), and 16000 rpm/24,320 x g (for TCR). The automatic rotor recognition system is only available for tabletop centrifuges.
The external body of Versati™ Centrifuges are made of electro-galvanized steel with antimicrobial coating. Most of the rotors and rotor lids are made of aluminum. Transparent rotor lids, caps, rotors, and buckets/ adapters are made of polycarbonate or polypropylene.
No. As of now, the maximum capacity of Esco Versati™ tabletop centrifuge is 1500 ml only.
Yes, for hospital use in centrifugation of blood and urine, we have rotor (VST-ROT-014) for tabletop centrifuge models with a tube capacity of 30 x 15 ml, maximum speed at 4500 rpm.
In fixed-angle rotors, it is acceptable if the rotors are not filled totally with either tubes/adapters as long as the weight of the samples are equal and is placed symmetrically. But, in swing-bucket rotors, it is necessary to put all the buckets/adapters in the carriers and load the samples in the bucket/adapter diagonally with equal weight.
The refrigerated centrifuge is best used when handling temperature-sensitive samples such as DNAs, RNAs, proteins and blood.
Relative Centrifugal Force (RCF) is measured in force x gravity or g-force. It is the force exerted on the contents of the rotor, resulting from the revolutions of the rotor. On the other hand, Revolutions per Minute (RPM) is describe as the speed of the centrifuge. The force applied to the contents varies by the size of the centrifuge rotor. RCF, not RPM, separates aqueous solutions in the centrifuge.
No, they may cause material damages and impair mechanical resistance.
The differences between micro centrifuge and tabletop centrifuge are the following:
1) Micro centrifuge can load a maximum volume of 88 ml while tabletop centrifuge can have a volume of up to 1500 ml.
2) The type of rotor that can be used for micro centrifuge is fixed-angled rotors only while for tabletop centrifuge, swing-out rotors and fixed-angled rotors can be used.
3) Tabletop centrifuge has a rotor auto-recognition system, no need for manual setting of rotor type. On the other hand, micro centrifuge does not have an automatic rotor detection system, so there is a need for manual setting of rotor type.
