In 2008, the Invitrogen Countess Automated Cell Counter was launched and became almost instantly famous for saving researchers from the tedious task of manual cell counting. Later in 2014, high-performance Invitrogen Countess II and Countess II FL Automated Cell Counters were launched, which were equipped with advanced autofocusing and image processing algorithms, enabling researchers to count cells accurately and faster, while minimizing user-to-user, sample-to-sample, and slide-to-slide variabilities associated with manual counting. The updated Countess II FL Automated Cell Counter with additional detection methods has been the state-of-the-art model with superior capabilities to address various research needs of customers. Here, we introduce the top 10 reasons behind choosing Countess II and Countess II FL Automated Cell Counters.
