ESCRIPTION
AquaPen (AP) is a lightweight, hand-held fluorometer intended for quick and reliable measurements of photosynthetic activity in algal,
cyanobacterial or plant cell suspensions. The photosynthetic activity is derived from the chlorophyll fluorescence (ChlF) kinetics. ChlF is
determined based on a Pulse Amplitude Modulated technique (PAM). For user convenience, all illumination protocols are predefined
and AP offers a set of illumination protocols (more in chapter
Error! Reference source not found. ) to determined fast fluorescence k
inetics known as OJIP-test as well as slow ChlF kinetics such as quenching analysis or Light response curve.
AquaPen is available in two versions: AquaPen-C AP110-C and AquaPen-P AP110-P.
AquaPen AP110-C, cuvette version is equipped with blue (455 nm) and red (630 nm) LED emitters whereas AquaPen AP110-P, probe
version incorporates just blue (470 nm) LED emitter. These are optically filtered and precisely focused to deliver PAR values of up to 3,000
μmol.m -2 .s -1 to measured volume. Blue excitation light is intended for excitation of chlorophylls and thus for measurements of algal
cultures and plant cell suspensions. Red-orange excitation light is suitable for measurements of cyanobacteria which tend to absorb
inefficiently the blue light.
AquaPen-P AP 110-P is a probe version, which allows detection of chlorophyll fluorescence in liquid samples by directly submersing the
probe in the suspension medium. It is designed for laboratory measurement and for field studies (in ponds and natural bodies of water).
This AquaPen version is supplied with single blue LED emitter (optionally red or white).
AquaPen-C AP 110-C is a cuvette version of the fluorometer. The sample is measured in a plastic cuvette inserted into an optical holder
with a lid. This version of the AP can also be used in laboratory conditions or field studies where samples of suspension may be obtained
and placed in the AP. The AP 110-C contains a built-in turbidity meter for measurements of optical densities in addition to chlorophyll
fluorescence. The AP 110-C also contains two LED emitters, blue and red.
Both AP versions have ultra- high sensitivity to chlorophyll with detections of up to 0.5 μg Chl/l – therefore natural water samples
containing very low concentrations of phytoplankton can be measured.
AP can be operated as a stand-alone instrument. Measured data are sequentially stored in the internal AquaPen memory. Data transfer
is via USB and Bluetooth communication. Comprehensive FluorPen 1.1 software provides data transfer routines and many additional
features for data viewing in tables and graphs.
AP 110-P does not measure Optical Density.
