What is
the sensitivity of the QuantiFluor™-P Fluorometer?
The QuantiFluor™-P 's sensitivity is defined in terms of the minimum detection
limits of dsDNA and RNA. The QuantiFluor™-P Fluorometer can detect:

What is
the optical configuration of the QuantiFluor™-P Mini-Fluorometer?
The QuantiFluor™-P UV/BLUE has two dedicated optical channels.
UV: Ex 365 nm, Em 440-470 nm
BLUE: Ex 460 nm, Em 515-575 nm
The QuantiFluor™-P GREEN/BLUE has two dedicated optical channels.
GREEN:
Ex 525 nm, Em >570 nm
BLUE: Ex 460 nm, Em 515-575 nm
What size
sample tube/cuvette is standard with the QuantiFluor™-P Fluorometer?
The standard cuvette size for the QuantiFluor™-P Fluorometer is 10 x 10 mm plastic
cuvettes. With the optional Minicell Adapter, 75-250µl minicell vials can be used.
What is
the Minicell Adaptor?
The QuantiFluor™-P Minicell Adaptor is designed to accommodate the measurement
of small volume samples.
Do the
sample tubes/cuvettes require minimum volumes? If so, what are they?
Sample tubes do require minimum volumes so that enough sample is exposed
to the incoming light. The minimum volumes are as follows:

What kind
of cuvettes should I use with the QuantiFluor™-P Fluorometer?
Methacrylate or polystyrene 10 x 10 mm cuvette, or 10 x 10 mm adaptor that
is designed for fluorescence measurement is appropriate. Due to the natural
fluorescence properties of polystyrene, this material is not recommended
for UV applications. The following sample tubes and cuvettes are available
for purchase from us:
10 x 10 mm Square Polystyrene Cuvette (3.5 mL)
10 x 10 mm Square Methacrylate Cuvette (3.5 mL)
Minicell Borosilicate Glass Cuvette (75-250 mL)
Can I
use a quartz or glass cuvette?
The sample compartment cannot accept glass or quartz cuvettes. Glass and quartz cuvettes have a slightly different shape and will damage the sample holder and optics if inserted into the instrument.
Can I wash cuvettes and re-use them?
Cuvettes for the QuanitFluor™ instruments are single use only. We do not recommend washing and re-using cuvettes.
Does the
QuantiFluor™-P Fluorometer have changeable optical filters?
No, the QuantiFluor™-P Fluorometer does not have changeable optical filters.
If the QuantiFluor™-P Fluorometer's optical configuration does not fit your application
requirement, please see information about the
GloMax-Multi Jr Single Tube Multimode Reader.
What is
the dynamic range of the QuantiFluor™-P Fluorometer?
The dynamic range of the QuanitFluor™ Instruments is 4 logs, assay dependent. Dynamic range is often assay dependent because the assay background signal may limit the lower detection limit of the fluorophore and the fluorophore maximum intensity may limit the detection maximum of the fluorophore independent of the instrument.
