Reviews
The QFX Fluorometer has a 4.8 / 5 star rating on SelectScience from independent scientist reviews.
The instrument is very helpful to estimate DNA from processed and degraded samples which have a very low concentration in extraction, as it can measure DNA between 0.5 pg/µL and 4000 ng/µL. It is more sensitive and reproducible than its competitors in the market. It is very user-friendly and can provide results in 2 seconds. It can also quantify proteins so it is a must buy an instrument for any laboratory.
