Compact, easy to use, and cost-effective single tube fluorometer for Life Science applications.
The QuantiFluor™-ST Fluorometer replaces the Turner BioSystems TBS-380 Fluorometer. Same instrument... new look!
OVERVIEW
The QuantiFluor™-ST is an affordable, sensitive fluorometer designed for quick, easy, and accurate fluorescence measurements. The QuantiFluor™-ST provides high sensitivity for fluorescence measurements and is so easy to use that you can have results within minutes. Single-point calibration saves time and the dual-channel design allows you to switch between two assays with the touch of a button.
UNIVERSAL POWER
The QuantiFluor™-ST is powered using a universal power adapter (included).
SMALL AND SENSIBLY PRICED
The QuantiFluor™-ST is smaller than a standard sized book, saving you valuable bench space. It is sensibly priced to meet your need for accurate fluorescence measurements within a limited budget.
SIMPLE
The QuantiFluor™-ST is designed for fast, accurate fluorescence measurements. It is so easy to use that you can have results within minutes without training.
DUAL CHANNEL
Dual UV and Blue Channels allow you to switch between two assays by pressing one button.
PCR TUBE ADAPTER
An optional PCR Tube Adapter allows measurement of small fluorescence sample volumes (100µl minimum) in 0.5 mL PCR tubes without sacrificing instrument sensitivity.
MINICELL ADAPTER
The optional Minicell Adapter with two focusing lenses allows you to measure samples in low assay volumes without losing sensitivity. When used with this Minicell Adapter, the QuantiFluor™-ST can detect 50 pg of dsDNA in a 50 µL assay volume.
CALIBRATION
Single-point calibration improves accuracy while saving time.
INTERNAL DATALOGGING
An internal datalogging package with software that interfaces with Microsoft Excel can log up to 1,000 data points.
