Excedr’s centrifuge leasing program provides you with the following advantages:
- Leasing eliminates the upfront price tag of buying equipment and allows you to make payments over time
- Payments may be 100% tax-deductible*, which yields you additional savings
- We minimize instrument downtime with our complete repair coverage
- Excedr takes care of the admin work associated with equipment procurement and upkeep
- With the cash saved through our program, labs are better able to reinvest in their core business and operations (staffing, inventory, marketing/sales, etc.)
*Please consult your tax advisor to determine the full tax implications of leasing equipment.
Centrifugation is used in a variety of laboratories for many different types of separation.
Whether you need to separate mixtures with close densities, blood, insoluble particles, or immiscible liquids, sediment suspended solids, or even simulate different types of gravity for astronaut training, a centrifuge is an indispensable piece of equipment. This device!centrifuge is an instrument that puts an object in rotation around a fixed axis, applying a potentially strong force perpendicular to the axis of spin.
There are three types of centrifuges designed for various applications. Industrial-scale centrifuges are commonly used in manufacturing and waste processing to sediment suspended solids, or to separate immiscible liquids. Very high-speed centrifuges and ultracentrifuges able to provide very high accelerations can separate fine particles down to the nano-scale, as well as molecules of different masses. Gas centrifuges are used for isotope separation.
Centrifuge Types, Designs, and Uses
A centrifuge can be described as a machine with a rapidly rotating container that applies centrifugal force to its contents. There are multiple types of centrifuge, which can be classified by intended use or by rotor design.
Types by Rotor Design

- Fixed-angle centrifuges are designed to hold the sample containers at a constant angle relative to the central axis
- Swinging head (or swinging bucket) centrifuges, in contrast to fixed-angle centrifuges, have a hinge where the sample containers are attached to the central rotor. This allows all of the samples to swing outwards as the centrifuge is spun
- Continuous tubular centrifuges do not have individual sample vessels and are used for high volume applications
Types by Intended Use

- Laboratory centrifuges are general-purpose instruments of several types with distinct, but overlapping, capabilities. These include clinical centrifuges, superspeed centrifuges and preparative ultracentrifuges
- Analytical ultracentrifuges are designed to perform sedimentation analysis of macromolecules using the principles devised by Theodor Svedberg
Haematocrit centrifuges are used to measure the volume percentage of red blood cells in whole blood
- Gas centrifuges, including Zippe-type centrifuges, for isotopic separations in the gas phase
A wide variety of laboratory-scale centrifuges are used in chemistry, biology, biochemistry, and clinical medicine for isolating and separating suspensions and immiscible liquids. They vary widely in speed, capacity, temperature control, and other characteristics.
Laboratory centrifuges can often accept a range of different fixed-angle and swinging bucket rotors able to carry different numbers of centrifuge tubes while being rated for specific maximum speeds. Controls vary from simple electrical timers to programmable models able to control acceleration and deceleration rates, running speeds, and temperature regimes.
Ultracentrifuges spin the rotors under vacuum, eliminating air resistance and enabling exact temperature control. Zonal rotors and continuous flow systems are capable of handling bulk and larger sample volumes, respectively, in a laboratory-scale instrument.
Types of Centrifugation

- Differential centrifugation, often used to separate certain organelles from whole cells for further analysis of specific parts of cells
- Isopycnic centrifugation, often used to isolate nucleic acids such as DNA
- Sucrose gradient centrifugation, often used to purify enveloped viruses and ribosomes, and also to separate cell organelles from crude cellular extracts
Types of Laboratory Centrifuges
Learn MoreShow Less
- Microcentrifuges – devices for small tubes from 0.2 ml to 2.0 ml (microtubes), up to 96 well-plates, compact design, small footprint; up to 30,000 g)
- Clinical centrifuges – moderate-speed devices used for clinical applications like blood collection tubes
- Multipurpose high-speed centrifuges – devices for a broad range of tube sizes, high variability, big footprint
- Ultracentrifuges – analytical and preparative models
Because of the heat generated by air friction (even in ultracentrifuges, where the rotor operates in a good vacuum), and the frequent necessity of maintaining samples at a given temperature, many types of laboratory centrifuges are refrigerated and temperature controlled.
We Offer Flexible Laboratory Centrifuge Leases to Fit Every Need
This off-balance sheet financing structure provides three options at the end of the term. The lessee has the option to return the equipment to the lessor, renew at a discounted rate, or purchase the instrument for the fair market value. Monthly payments are also 100% tax deductible which yields additional monetary savings.
If you recently bought equipment, Excedr can offer you cash for your device and convert your purchase into a long-term rental. This is called a sale-leaseback. If you’ve paid for equipment within the last ninety days, we can help you recoup your investment and allow you to make low monthly payments. This also frees up money in your budget rather than tying it down to a fixed asset.
