Top 10 Best Lab Centrifuges For Sale In 2017 Reviews
Whether you are a technician, research assistant, or just looking to bolster your lab equipment for independent lab use, lab centrifuges will be vital. Centrifuges work by applying centrifugal force to various tubes inside the machine. This separates fluids, gas or liquids outward based on its density as it spins. This is a very useful function for harvesting cells, viruses, proteins, DNA/RNA research and other fluids.
Benchtop centrifuges are excellent for most lab applications. They are not as powerful as the larger floor standing versions, but they come at a much cheaper price point. The most important to consider is the relative centrifugal force (RCF). Typically, the higher the RCF, the more efficient it will be at separation. Speed is also measured in terms of revolutions per minute (RPM), and variable speed options are good to have. Another important factor is cooling and noise. Excessive noise can be very distracting if you have to frequently use it. Decent ventilation or internal cooling systems ensures that your samples are not heating up as they spin.
This model is fairly compact and versatile, ensuring efficient results every time. It can spin up to eight 15 mL test tubes, or 7 mL test tubes using the small tube sleeve insert. You can set the variable-speed centrifuge between 550 and 3300 rpm, which can produce an RCF of up to 1350 x g. To prolong the centrifuge life, it features a brushless motor that will automatically stop if the unit is opened during operation, and there is a vortex ventilation system in place to protect your samples inside the chamber. There is an easy-to-read digital display with touch controls to change the time, speed, and on/off.
For any small or moderate sized task, this centrifuge is sturdy enough to handle them all. It features a variable-speed configurations that range from 1000 to 4000 rpm. It has a max RCF of 1790 x g. It has a 1 to 60 minute timer with a hold function, and for extra convenience, there is a memory function that remembers that last operation settings. It features a six-place rotor for 10mL or 15mL tubes. This unit weighs just 13 lbs and it uses 80 watts of power.

The timer is settable between 1 and 99 minutes. This non-refrigerated centrifuge is slightly larger than most other benchtop models at 10 kg, but it does have a more impressive capacity. It can accept up to six 50 mL tubes. In addition to that, it is compatible with various swing-out rotors and adapters for different sized tubes, which can be purchased separately.
If you’re interested in leveraging centrifugal force in a slightly different application in your kitchen, check out this milk separator by Motorsich. This machine makes processing whole milk much simpler. It can be used to prepare any dairy product using the same physics principles as centrifuges. The spinning motion helps separate the fat from the milk, due to the density difference between the two. This separator features a manual driving gear that is easy to use and works effectively.
5. Benchmark Scientific BSC1006-B
