"I purchased the instrument upon development of a new Cell Biology Laboratory course. At first, I thought it was a great product because it was relatively easy to use & worked well for students in the course. Unfortunately, the unit lasted for just over a year before the electronic board inside it malfunctioned. As infrequently as it was used (probably less than 25 times total), I find that completely unacceptable. My options for repair include a $1655 charge or a $500 service charge just to look at the instrument & give me a quote. Seeing as I am working on a shoestring budget (in a primarily-undergraduate institute), I'm going to have to just shelve the instrument. Overall, purchasing this piece of equipment has been my worst decision in 10 years of running a lab. Severely disappointed. "

"This automated cell counter is user-friendly. "

"For a large number of cell lines, the cell counter is perfect. Simple, fast and accurate! Since we have the TC20 our Millipore Scepter is only in the drawer. The Scepter was delicate, expensive and often defective. The TC20 is used all day every day and has never made problems for now about 3 Years!"

"This cell and particle counter is very easy to use, provides results in a quick and simple way, and is suitable for counting magnetic beads, to be used in immunoassays. Its cost and no need of maintenance makes it an excellent tool for lab workers, especially when compared to traditional cell counters. "
