A must read guide to buying a laboratory centrifuge

There are many different factors that you need to consider when investing in a laboratory centrifuge.

  • This small brief may have answered your questions as to what is a centrifuge used for in a lab; but it does not mention how to use a centrifuge or even what is the purchasing procedure of a centrifuge.
  • In general a laboratory centrifuge is used only by certified operators who are fully aware of the risks involved in operating the centrifuge device and thus can take the appropriate precautions.
  • That said it is not hard to operate a laboratory centrifuge though there are several facts that you should be aware off, but I digress.

Hence coming back to topic on the factors that you need to consider before buying a laboratory centrifuge; here are a few tips:

Capacity and size of laboratory centrifuge:

  • It is vital that you know the capacity of the centrifuge prior to buying it since the centrifuge is then governed by those limitations.
  • There are a limited number of sample tubes that can he placed inside a centrifuge for one given run.
  • Thus you need to make sure you know how many sample tubes you would generally require to place in the centrifuge at a time.
  • In general the maximum sample tubes that the centrifuge can hold in one run is called the capacity.
  • There are centrifuge rotors that can spin 18 to 24 1.5 ml to 2.0 ml tubes.

laboratory centrifuge Safety:

  • There may be times when you will have the need to use hazardous materials as sample inside the test tubes.
  • The basic instinct while using hazardous substances is to be wary of it.
  • With the centrifuge devices there are changes the tube may break while handling or transporting.
  • Such an incident could cause the entire laboratory to be contaminated. Additionally it is a good idea to make sure that the centrifuge device has as auto shut down feature if the lid is opened.
  • The rotor lid are at times made from plastic or metal. Plastic lids can be transparent and prevent corrosion while the metallic ones have the advantage of being stronger and thus don’t break easily.

Usability of laboratory centrifuge:

  • A laboratory centrifuge is used day in and day out in a laboratory and hence can take its toll on an operator.
  • This can very easily be prevented by making sure that the laboratory centrifuge selected at easy to operate.
  • A device that is easy to use and operate is bound to help improve the performance of the operator who is then less likely to make mistakes.
  • A centrifuge device which have feature where the rotors are interchangeable.

Additional factors that you should consider prior to buying a laboratory Centrifuge:

  • It is important to check the spin speed. Revolutions per minute of the centrifuge will vary and hence the speed requirements of your applications should be taken into account.
  • Furthermore the programmability of the centrifuge should be checked and made sure that it meets your individual requirements.
  • You also have a choice to make between a refrigerated and a non-refrigerated one. The interior of the refrigerated on will help to protect the sample from any damage caused due to heat.
  • Check the tubes as well which could be either plastic or glass.
  • Also take the dimensions of the tube into consideration since some centrifuges have tubes will small capacity that is not suitable for all experiements.
  • A centrifuge with a brushless motor would be virtually maintenance free and thus is an ideal option for just about any laboratory.And if a stainless steel bowl would be used, it will ensure that it can easily clean out.
  • Centrifuges that consist of a digital display showing status, time, speed and RCF(g) have a greater advantage again.
  • It is important to make sure you always look for a centrifuge with the latest technology. Usually good quality centrifuges that have the advanced technology are more accurate and better throughput.
  • Opting for branded centrifuges can go a long way in providing peace of mind and good quality.

Laboratory Centrifuge Specifications:

The technical specifications to look out for in a laboratory centrifuge are as below:

  • Capability and applications.
  • The programmability
  • Whether it is refrigerated or non-refrigerated.
  • Protocols for centrifugation.
  • Dimensions of the tubes themselves.
  • Protocols for centrifugation.
  • Sample volume and throughput.
  • Safety
  • Speed
  • Motor and noise level
  • Hermetically sealable lids on rotor or buckets.
  • Accuracy.
