First Use Experience
My initial testing took place in our molecular biology lab, where temperature-sensitive RNA and protein samples are routinely processed. The Beckman Coulter Microfuge 22R was put through its paces with a series of RNA isolations and protein precipitations, requiring precise temperature control and consistent centrifugation speeds. The refrigerated aspect was crucial for maintaining the integrity of the RNA samples.
Even with the lab’s temperature fluctuating, the Microfuge 22R maintained a consistent internal temperature. The digital display was clear and easy to read, and setting the parameters for time, speed (RPM/RCF), and temperature was straightforward.
The learning curve was minimal, thanks to the intuitive interface. A minor initial issue was figuring out the best method for balancing the rotor with varying sample volumes, but this was quickly resolved with a bit of practice and proper tube placement.
Extended Use & Reliability
After several months of almost daily use, the Beckman Coulter Microfuge 22R has proven to be a reliable workhorse. The refrigeration system has consistently maintained the set temperature, and the brushless induction drive operates quietly and efficiently. The included Beckman Coulter 368894 Rotors F301.5 rotor shows no signs of wear, even after repeated autoclaving.
Aside from routine cleaning of the rotor chamber, maintenance has been minimal. I’ve noticed no signs of corrosion or material degradation, which is impressive considering the frequent exposure to various chemicals and samples.
Compared to my previous microcentrifuge, the Beckman Coulter Microfuge 22R is a significant upgrade. It offers superior temperature control, higher speeds, and significantly quieter operation, leading to more reliable results and a more pleasant lab environment.
