What is a microcentrifuge?

A microcentrifuge is an important piece of equipment for any laboratory, as it is used for spinning a variety of samples at high speed, enabling, for example, the pelleting of nucleic acids or proteins from solution, microfiltration of small aqueous samples and gathering liquid into the bottom of a tube to avoid …

What is the difference between centrifugation and centrifuge?

Centrifugation is a technique that helps to separate mixtures by applying centrifugal force. A centrifuge is a device, generally driven by an electric motor, that puts an object, e.g., a rotor, in a rotational movement around a fixed axis.

What are the two types of centrifuges?

Generally, there are two types of centrifuges: the filtration and sedimentation centrifuges.

What are the three types of centrifuge?

Three types of centrifuge rotor. Centrifuge rotors fall into three categories: swinging-bucket rotors, fixed-angle rotors, and vertical rotors. Each category is designed to address three key factors: 1) type of centrifugation (differential, rate-zonal, or isopycnic), 2) speed, and 3) volume range.

What is called centrifugation?

Centrifugation is a method of separating molecules having different densities by spinning them in solution around an axis (in a centrifuge rotor) at high speed. It is one of the most useful and frequently employed techniques in the molecular biology laboratory.

When spinning your samples in the microcentrifuge it is important to?

Prepare the samples that you want to spin down. It is important to always have your samples located close to your microfuge when you are working to minimize the distance you need to move things and to avoid shaking-up your sample after centrifugation.

What are rotors in centrifugation?

A centrifuge rotor is the rotating unit of the centrifuge, which has fixed holes drilled at an angle. Test tubes are placed inside these holes and the rotor spins to aid in the separation of the materials. There are three types of centrifuge rotors: swing-bucket, fixed-angle and vertical rotors.

What is a Serofuge?

A Serofuge is a piece of laboratory equipment that is used in blood banking by spinning the serum from whole blood red cells. Rouleaux detection, agglutination grading, and direct antibody testing and antibody identification are just some of the test serum is used for in blood banking.

What is the difference between centrifugation and ultracentrifugation?

As verbs the difference between ultracentrifuge and centrifuge. is that ultracentrifuge is to submit a material to ultracentrifugation while centrifuge is to rotate something in a centrifuge in order to separate its constituents.

What are centrifuge rotors made of?

Aluminum, having a low density, is a commonly used material for superspeed and benchtop centrifuge rotors. The greater structural properties of titanium are better suited for ultracentrifuge rotors, which experience the highest level of stress of all rotors.

What is RPM centrifuge?

RPM (revolutions per minute) is the way in which we describe how fast a centrifuge is going. This is the rate at which the rotor is revolving regardless of its size. G-Force or RCF (relative centrifugal force) is the force being exerted on the rotor contents.

What is swinging bucket centrifuge?

Swinging-bucket centrifuge rotors feature a full pathlength, slow run time, and excellent resolution. The swinging bucket rotor allows the tube to change angle during the run. The buckets are vertical when stopped and horizontal when running.

Why the slip is never zero in an induction motor?

In motors the number of rotor slots and stator slots are different and thus cogging (magnetic locking) can’t happen. And thus The slip motor can’t run at rated speed. Torque developed by induction motor is proportional to the slip.

Whats better drilled or slotted rotors?

Given the choice between drill holes and slots, the drill holes will give you better braking power over slots for normal city/highway driving. This is why high end BMW, Porsche, Corvette, and Mercedes rotors are drilled, not slotted. However, for track racing (high speed stops), slotted rotors are the better choice.

What are slotted rotors?

Slotted rotors are brake rotors with slots etched onto the friction surface of the rotor. These slots help “wipe” the brake pad clean during each pass and help maintain an even pad wear as well as performance.

Are drilled and slotted rotors less likely to warp?

Cross drilled rotors and cross drilled and slotted rotors will provide better heat ventilation. It will bring the temperature of the rotor down to a point where heat spots are least likely to form. Cross drilled rotors will prevent the glazed effect from brake pads.

Are vented rotors better than solid?

Vented rotors are a better option than traditional solid rotors. They dissipate heat better and don’t warp or fade as much as solid rotors.

Are zinc plated rotors good?

Zinc Plating is more efficient than other processes. It has been found to give longer protection to brake callipers and steel in general, thereby providing a vehicle with reduced risk of damage over time.

Why drilled and slotted rotors are bad?

Drilled & slotted rotors are not recommended for performance racing since the drilling makes them vulnerable to cracking.

Can you put vented rotors on the rear?

Vented rotors are usually installed on the front axle due to the vehicle’s Brake Bias. However, vehicles with a performance braking system can also have vented rotors on the rear axle.
