Features to Look for When Buying a
Centrifuge
www.blockscientificstore.com
Centrifuges, used for processing blood samples of varying density, are very much in demand in medical and clinical laboratories. There are many different brands and models of this piece of lab equipment such as benchtop, horizontal and microhematocrit centrifuges. Laboratories
choose
a
suitable
model
based
on
their
performance
requirements, budget and space availability. Here are some of the factors that should govern centrifuge purchase decisions
Size The device come in a variety of sizes and shapes and range from benchtop models to floor-standing models. Benchtop centrifuges occupy less space. This makes them a cost effective solution for those small medical laboratories. Some of the top centrifuge models offered by leading suppliers include StripSpin™12 Mini centrifuge, PowerSpin Porta-Spin Portable Centrifuge C828H, Octafuge Plus 220V Centrifuge and PowerSpin MX C8606E.
Capacity This is an important feature to be considered by medical laboratories before buying a centrifuge. A bench top model will be suitable for small laboratories or clinical settings have smaller samples for separation. On the other hand, for high-throughput laboratories larger models are more suitable as they can offer a larger number of tubes per run.

Programmability A programmable centrifuge will be an ideal choice for those laboratories, who conduct clinical applications at variable speeds and temperatures. For repetitive centrifugations, a pre-set model will be more cost-effective.
Speed Before choosing a centrifuge model, it is important for medical laboratories to determine the actual speed/g force required and choose the device on that basis. Hence, verify whether the device selected is able to reach the set speed levels. This can be done by checking the speed/force ratings on your centrifuge tubes. StripSpin™12 Mini Centrifuge by Benchmark Scientific is a good option for those laboratories want a model with a speed of 5,500rpm.
Temperature Different models of centrifuges include a refrigeration and non-refrigeration option. The refrigeration feature will protect the samples from heat. Some of the top model centrifuges also have additional options like last run memory or over-speed running.
Power Supply Before selecting a specific centrifuge model, laboratories must check the voltage/plug to make sure whether the centrifuge chosen is compatible with their electricity supply.

Tube dimensions Check the tube, which may be made of glass or plastic. Consider the dimensions of the tubes. Microcentrifuges that are used in research labs have tubes of very small capacities. Make sure you get the tube size suitable for your application.
Choose a Reliable Lab Equipment Supplier To buy centrifuges, you need to find a reliable and reputable lab equipment supplier. An online search will help you to locate the top suppliers offering quality lab instruments. A reliable supplier will offer top centrifuge models with advanced features at an attractive price as well as impressive post-sales service and warranty. Reputable dealers will also supply different accessories like tubes, microtitre plates, rotor adapters and cell culture packages along with a centrifuge model.
