AlgaeTorch

Measurement of cyanobacteria with the AlgaeTorch from bbe Moldaenke

In-situ measurement of cyanobacteria has never been easier…. Power up, submerge and measure!

The AlgaeTorch is lightweight, field-portable, and designed to measure total chlorophyll and blue-green algae (cyanobacteria).  The pigments of the algae are spectrally excited subsequently by three colored LEDs at a high frequency.  In response, the algae emit red fluorescence light and the intensity of this light is used for the calculation of the different algae types (i.e. blue-greens and total micro-algae).  Results are displayed and stored in the internal memory and can easily be transferred to a PC via the USB port for further analysis.

BenthoTorch

Measurement of benthic algae with the Benthotorch from bbe Moldaenke

In-situ measurement of benthic algae has never been easier…. Power up, place head on sample and measure …

… and get your results in less than 15 seconds!

The BenthoTorch is lightweight, field-portable, and designed to measure benthic algae in real-time and in situ by utilizing fluorometric characteristics of the different algal pigments in the intact cell.  No sample preparation is required.  Results are displayed and stored in the internal memory and can easily be transferred to a PC via the USB port for further analysis.

Innovative concept. Fast & easy measurement.

The Benthotorch has made benthic algae measurements an entirely new experience. Different light sources excite the internal pigments of intact algal cells. The amount of re-emitted red light fluorescence gives a quantitative estimate of the algal density without the need for sample prep, enabling quick and easy analysis of benthic algae in real-time. The BenthoTorch is precalibrated for the most prominent algal classes to be found in the field.

This fluorometric technique has been well-proven for pelagic phytoplankton by extensive application of the bbe FluoroProbe, and has now successfully adapted to measure benthic algae concentrations.The BenthoTorch includes an additional LED (700nm) that is used to compensate the chlorophyll measurements due to reflectance caused by the background substrate material (e.g. silt, rock, etc.).

It is operated through transparent housing using capacity keys located below the display. The key actions are confirmed by a vibration signal, ensuring the safe operation of the instrument even in a wet environment. The instrument can be deployed down to a depth of 10 m without the need for power due to the internal rechargeable batteries.

FluoroProbe III

Fluoroprobe from bbe Moldaenke

A unique in-situ spectrofluorometer that provides accurate measurements of up to 5 different algae classes and total chlorophyll in one portable unit.

The FluoroProbe III quickly and reliably determines chlorophyll concentration down to depths of 100 meters making it ideal for depth profiling.  Measurements can be displayed online via a serial interface or stored in the probe for subsequent analysis.  In addition to determining the chlorophyll content, the probe also detects the presence of algae and allocates them to various spectral algae classes (i.e. blue-green algae / cyanobacteria, green algae, diatoms / dinoflagellates / chrysophytae, cryptophytae).  This enables the instrument to analyze the occurrence and distribution of algae on-site without the necessity of the laboratory.

PhycoProbe

Depth-profile with quick analysis of chlorophyll and unbound phycocyanin concentrations as well as algae classes

Quick analysis of chlorophyll and phycocyanin

Measurement Chamber

NEW! Depth-profile with quick analysis of chlorophyll and unbound phycocyanin concentrations as well as algae classes

The bbe PhycoProbe* is a highly sensitive measuring instrument for the in vivo analysis of chlorophyll-a in real microalgae and blue-green algae (cyanobacteria). Individual profiles for the different algal classes are created during the measurement. The algal content is determined by evaluating the chlorophyll fluorescence in real-time. Without the necessity of using a laboratory, it is possible to completely analyse the occurrence and distribution of algae in different water bodies, if necessary at different depths.

Additionally, the PhycoProbe measures the amount of unbound phycocyanin (free PC) which reflects the release of blue-green algae contents like toxins as well as flavors and odorous substances. Interference from e.g. humic substances is compensated using the integrated yellow substances measurement.

Hydro-Wiper unit to prevent biofouling

The PhycoProbe can now be operated on moored platforms, submersed from buoys or fixed measuring stations using the Hydro-Wiper (made by Zebra-Tech Ltd, NZ). The wiper brushes can be set to periodically clean the lenses of the measuring chamber to remove biofilms and dirt which builds up over long periods of operation.
