Centrifuges Vital for Medical Laboratories

Centrifuges are a highly useful and valuable piece of lab equipment in clinical and research settings. Driven by a high speed centrifugal force, the instrument is used to separate sample components of varying densities in an efficient manner.

Different models of centrifuges integrated with advanced technologies and features are available today. It is very important to purchase top quality, branded instruments to ensure accuracy and reliability. Leading manufacturers offer various models of laboratory centrifuges (both bench top and floor models) with advanced features and specifications. When buying a device, it’s important to evaluate your specific requirements and choose the device that can meet them. The article gives an overview of why centrifuges are vital for medical laboratories.

Laboratory Centrifuges - Different Applications

Centrifuges are used for a wide variety of applications in both small and large medical laboratories and research facilities. Research and medical laboratories use this lab device to separate proteins and chemicals from blood samples. They are also used to separate plasma from blood in order to remove pure serums to be used for several testing procedures.  Centrifugal machines are also used by clinical test laboratories to segregate the different components of urine and blood. The lab equipment is also used in blood banks to separate unique components of blood like plasma from direct transfusion. They are used to process large samples of blood for future use in blood banks.

Centrifuges are available in different models and sizes. Leading manufacturers take care to supply instruments that can deliver accurate, timely, and consistent results. Medical laboratories with space constraints can opt for bench-top centrifuge models. Top quality devices make the centrifuging process quicker and easier. Before purchasing a centrifuge, medical laboratories need to consider the following factors

  • Type of centrifuge
  • Features and specifications
  • Accuracy of result
  • Budget limits
  • Warranty
  • Post-sales support

Top Models of Centrifuges

  • Octafuge Plus 220V Centrifuge - Manufactured by Block Scientific, this is an 8-place 3-15ml tube with a fixed speed rotor with 3300 RPM and timer. The centrifuge model features an angled rotor and has a total of 8-tube capacity (3ml to 15ml size tubes). With reduced functional errors, this model features a brushless motor of 110V (maintenance free), auto-off 30-minute timer with bell and a Blue LED power indicator light as well.

  • PowerSpin MX 50mL Horizontal Centrifuge - This is a new centrifuge model by Unico that features a horizontal swing-out rotor that provides high G-force and flat separation meniscus line. It includes a 4 place swing-out horizontal spin rotor for 50 ml tubes and spins at a variable speed of 1000 – 3400 RPM.

  • HemataSTAT II Microhematocrit Centrifuge - This centrifuge model from Separation Technology, Inc., can measure hematocrit in any setting. With a whisper quiet operation, this model features a 6-place rotor with a total spin time of 60 seconds.  It is possible to measure the percentage of red blood cells in a blood sample with this model.

  • E8 Centrifuge - This is a unique centrifuge model from LW Scientific that has a capacity to hold 8-tubes (3ml to 15ml size tubes). This is an economical fixed speed centrifuge designed to fit any budget that operates at a fixed speed of 3,300 rpm (for blood only). The centrifuge also features a brushless motor (110V only) and blue LED power indicator light.

Choose a Reliable Laboratory Equipment Supplier

It is very important to select a reliable and established laboratory equipment supplier for purchasing centrifuges. This will provide the advantage of being able to choose from top brands at competitive prices. Reputable laboratory equipment suppliers offer both new and recertified lab equipment. In addition, professional lab equipment suppliers will provide excellent post-sales support.
