Sensitive Fluorometer
The TBS-380 Mini-Fluorometer provides high sensitivity for fluorescence measurements. The new Minicell Adaptor with two focusing lenses allows you to measure samples in low assay volumes without losing sensitivity. When used with the Minicell Adaptor, the TBS-380 Mini Fluorometer can detect 50 pg of dsDNA in 50 µL assay volume using PicoGreen® reagent.

DQ300 Mini-Fluorometer Minicell Adaptor Kit
  • Measure sample volumes as low as 50 µL without losing sensitivity.
  • Adaptor fits into the DQ300 Mini-Fluorometer sample compartment.
  • Easy to use.

For applications where sample volume is a concern, the Minicell Adaptor with two focusing lenses allows you to measure sample in an assay volumes as low as 50
µL without losing sensitivity (e.g. 1 ng/mL dsDNA using PicoGreen, 50 pg of dsDNA in 50 µL assay volume).

The Minicell Adaptor Kit comes equipped with 500 borosilicate, flat-bottomed vials that are easily loaded in and out of the adaptor. The disposable vials eliminate potential cross-contamination and time-consuming cleanup required with non-disposable cells. Vials accommodate a sample volume range of 50-250 µL.

Straightforward easy to use Fluorometer
The DQ300 Mini Fluorometer is designed for fast accurate fluorescence measurements. Unlike larger, more complex fluorometers, it is so easy to use that you can have results within minutes without training or previous experience. The single point calibration saves time, and the dual-channel design allows you to switch between two assays with a single press of a button.

Low Cost Fluorometer
Small in size but big in utility, the DQ300
Mini-Fluorometer gives you the performance you expect from larger and more expensive instruments. Its inexpensive price meets your need for accurate fluorescence measurements within a limited budget. Although quite economical, the DQ300
Mini-Fluorometer provides superior sensitivity and reliability.
