Guava PCA-96

$65,000.00 Released January, 2003

Product Shot 1 The Pros:Reliability. Ease of use. Volumetric absolute counting.

The Cons:Clogs easily. Limited fluorescent parameters. Reagents for canned assays pricy.

The Guava PCA-96 System provides automated, higher throughput screening of 96-well microplates or a tray of microcentrifuge tubes. This flexible sample format makes the Guava PCA-96 System ideal for screening in basic research, target validation, assay development, and clinical trials.

Like its smaller cousin, the Guava PCA System uses a green laser for excitation, two fluorescence detectors, and a forward scatter detector for assessing relative size. The walkaway automated sampling of 96-well plates makes it easy to screen large numbers of samples and plates in one day.

Flowjock457: #guava_pca_96 To compare this instrument with the FACS Array isn't fair. This is a stand alone bench top flow cytometer while the FACS Array is a multiplexing instrument and not a cytometer in the true sense of the word. The better competitor for the FACS Array is the LX200 Luminex instrument. Dec 20, 10

We've had this in our lab for 2 years now and it has been a fantastic instrument. Cleaning and quality control couldn't be more straight-forward. The 96-well device is very well designed and manufactured. Zero problems thus far. The software is extremely simple to use and robust; program your plate layout, put in your plate and hit go. That simplicity comes at the expense of flexibility, but once you understand the instrument's purpose, this all makes sense.

We use it almost exclusively for cell count/viability of mouse splenocyte preps. Allowing the technicians to load 50+ samples at a time and walkaway is a huge time saver, not mention the improved accuracy versus manual counting. Dec 17, 10
