Things to consider while buying a Microcentrifuge

A Microcentrifuge is one of the most important equipment in a laboratory. This could be hospital laboratory a healthcare clinic or even a research laboratory. It has a vast number of applications and if considering to buy one you need to make sure you get the right type that meets your requirements.

A Microcentrifuge has a lot of features and the cost of microcentrifuge and availability will depend on the features you select. Thus to make sure you select the right set of features for your device there are a few factors mentioned in this article that you should consider.

Speed:

The speed at which the Microcentrifuge spins is of utmost importance thus this needs to be noted. Since the revolutions per minute of the device will vary in each device you need to have a set range of requirements prior to actually purchasing the device.

  • The Microcentrifuge should also have the right set of programmable features to meet your needs. The speed of the Microcentrifuge depends a lot on the type of sample that you wish to analyse. All samples have a set duration and speed that is required to be set of them.
  • It is important to note that the g-force and RCF are more important than the speed while selecting a Microcentrifuge.
  • It is possible to substitute the duration for the speed. For example if you are unable to set the desired speed on your Microcentrifuge device due to some reason or the other it is possible to lengthen the duration in order to achieve the desired result.

Temperature Sensitive Samples:

Microcentrifuges are of two different kinds; in the sense that one is refrigerated and the other is non-refrigerated. As the name suggests the refrigerated one will keep the sample placed inside very cool throughout the process thus preventing any damage to be caused to the sample.

Some of them offer additional features like last run memory or over speed running, etc. The perfect example of an industry where a refrigerated Microcentrifuge is required is the Medical Industry and especially the pathology department. If you have even been to the pathology laboratory you would have noticed that they all have cold storages used to store the blood necessary for patients. It is necessary to store blood in a cold storage in order for it to be used in blood transfusions. Again, the same thing applies while running tests on a blood sample as well. It is necessary to keep the temperature of the blood low while performing tests on it. Thus the refrigerated Microcentrifuge is perfect for this application.

Tube for Samples:

  • The tubes used in the Microcentrifuge to fill the sample are of great importance as well.
  • The tubes could be either glass or plastic, besides which the size also varies.
  • For example those devices that are used in research labs have tubes that have very small capacity.
  • The size really depends on the size allowed by your Microcentrifuge device.

If you do have a large Microcentrifuge you will usually have the option of using larger test tubes. In addition to which if you need to analyses larger samples you will need bigger test tubes for the sample.

Motor:

  • The brush-less motor is popular and is considered almost maintenance free; thus is the one you should consider opting for.
  • It is recommended that you use a brush-less motor for just about every minor requirement.
  • The brushless motor is the one to use for blood banks, chemical laboratories and just about any industry you can think off.
  • As far the bowl is concerned it would be best to opt for a stainless steel bowl ensuring easy clean out.

Display:

Some of the Microcentrifuge devices also sport a nice digital display that shows the status, time and speed. This can also be something you might want to consider.

Service:

After sales service is also important; maybe not as important as the Microcentrifuge device itself though.

Opting for a used Microcentrifuge:

Often these Microcentrifuge devices get rejected by a laboratory due to some minor defect. These devices that are thus obtained are fixed by trained technicians and refurbished; after which they function more or less as new.

  • You do have the option of opting for buying such devices if the budget is a constraint.
  • Such devices can also be considered reliable and a good alternative to a new one since usually parts warranty is offered.
  • At times you may end up with a very good quality product by paying half the price of a new one if not lesser. One of the popular places to purchase a used Microcentrifuge is ebay.com for example, which is a global website.

Specification:

The microcentrifuge specification tends to vary from device to device but here is the specifications of a Centrifuge device; which can act as a reference as to what to expect.

  • 8 Place closed rotor for 1.5/2.0 ml micro tubes (Rotor capacity)
  • 6000/2000g -> Maximum RPM/RCF(g) (Rotor)
  • Digital Display
  • Noise level of < 55db
  • 1 – 25 minutes and infinite mode (Duration settings)
  • Dimension (w x d x h) of 162 mm x 157 mm x 115 mm
  • Reduction adapters for 0.2 / 0.4 ml micro-tubes (Rotor and Adapter)

Cost of Microcentrifuge:

In order to make you aware of what features to expect in what price range a sample guide has been provided below with three different centrifuges and their price range.

  • Price range Rs 7000 to Rs. 9000: For this price range you could expect to be able to purchase a centrifuge with capacity of 4 tubes, each of 15ml with swing out head. The maximum RPM to expect would be in the range of 3100RPM, while the maximum R.C.F would be in the range of 1750g.
  • Price range Rs 20,000 to Rs 22000: For this price range it is possible to expect a centrifuge with 12 capillary tubes. The maximum speed would be up to 12000 RPM. The duration settings can range from 0 to 60 minutes.
  • Price range Rs 21,000 to Rs 23000: This is a higher price range and you can expect a higher specifications centrifuge for the price. It would be possible for you to obtain a centrifuge with about 24 capillary tubes in this price range. The speed would be approximately up to 12000 RPM and duration 0 to 60 minutes. In addition to which you can expect features like electrical lock and speed regulators.
