Water is the source of all life! Good water quality is a pre-requisite for our future and is a great challenge. To be involved in this, bbe has committed itself to water quality monitoring! WHO WE ARE AND WHAT WE DO For more than 20 years bbe Moldaenke GmbH has been one of the leading manufacturers of out‑ standing environmental technology products. bbe develops and produces measuring instruments and software for the monitoring of water quality. Our instruments are used e.g. in oceanography and limnology, in the analysis of drinking and raw water, in the measurement of bathing water...

CHLOROPHYLL & TOXICITY SOME FACTS ABOUT ALGAE DETECTION Chlorophyll is a universal pigment in the process of photosynthesis. It is distributed in all micro-phytoplankton and can be easily used for the estimation of the amount of microalgae and cyanobacteria in sample water. Beside microscopic analysis, the extraction of pigments and with measurement of chlorophyll absorption or fluorescence are widely used. Both methods are laborious and are subjected to limitations in accuracy and sensitivity. Nevertheless, the microscopic picture allows a classification of phytoplankton due to shape and...

AlgaeTorch FEATURES The user-friendly, handheld measuring instrument: switch on – dip in – read off! The bbe AlgaeTorch is a light handheld measuring instrument for the simultaneous detection of the chlorophyll-a of blue-green algae (cyanobacteria) and the total chlorophyll-a content of all microalgae present in the water. The measurement of chlorophyll-a fluorescence can replace laboratory analysis. A complete measurement requires less than 15 seconds. Sample-taking and preparation are unnecessary. With capacitive keys on the housing the AlgaeTorch is simple and easy to use. The instrument...

BenthoTorch FEATURES In-situ measuring instrument for the rapid and simple determination of the chlorophyll of benthic algae The bbe BenthoTorch is a reasonably priced instrument for the measurement of benthic algae concentrations in real time. It enables the immediate and reliable determination of algal growth for the estimation of primary production and for the analysis of ecological status (in accordance with the EU Water Framework Directive). The portable field instrument measures in vivo chlorophyll fluorescence in situ on different substrates such as stones or sediments without any...

The depth-profiling instrument for the rapid analysis of chlorophyll content and algal classes The bbe FluoroProbe III is a highly sensitive measuring instrument for the in vivo analysis of chlorophyll 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...

AlgaeLabAnalyser FEATURES Determination of chlorophyll concentrations, algal classes and photosynthetic activity for science and routine analysis The bbe AlgaeLabAnalyser offers the simultaneous determination of chlorophyll concentrations, transmission, and – as an option – the photosynthetic activity of microalgae in a 25 ml glass cuvette. The chlorophyll content is excited by coloured LEDs and allocated to the different algal classes. The AlgaeLabAnalyser enables direct measurement without sample preparation by filtration or solvent. The fluorescence signals f0, f, fm are used to...

AlgaeOnlineAnalyser FEATURES Online determination of chlorophyll concentrations, algal classes and photosynthetic activity The bbe AlgaeOnlineAnalyser is deployed in measuring stations and laboratories in which online measurement of water quality is required for rivers, reservoirs, dams and lakes as well as in drinking water production. The instrument impresses due to its rapid analysis of chlorophyll concentrations. The chlorophyll concentration, the transmission and optionally the photosynthetic activity are determined simultaneously. The detection of different algal classes by excitation...

IOcells FEATURES ▶ Field instrument with the highest sensitivity on the market Simple, quick and highly sensitive – the first choice for ballast water assessment! With the bbe 10cells device we have used our manufacturing experience of more than 2 decades of chlorophyll instrument production to venture into new measurement dimensions – the detection of single living algal cells. Microalgae are an ideal indicator in many applications since they make up the largest part of the biomass of small organisms. The 10cells is thus always the right choice when the smallest possible algal...

AlgaeToximeter II FEATURES ▶ Highest sensitivity in the detection of herbicides and their by-products The online instrument for the detection of toxic substances and herbicides in water The bbe AlgaeToximeter II continually monitors water for toxic substances and determines the algal classes present. Standardised algae are mixed with the sample water and their photosynthetic activity is determined fluorometrically. Damage to the algae – e.g. by herbicides – causes a reduction in photosynthesis and triggers an alarm above a user-defined threshold. Optionally, the sensitivity can be tested...

DaphniaToximeter II FEATURES ▶ 1- or 2-chamber system ▶ Simple operation Biological early warning system with daphnia and computer-controlled video evaluation The bbe DaphniaToximeter II observes daphnia (also known as water fleas – Daphnia magna) under the influence of a continuous flow of sample water and evaluates the occurrence of toxic substances using a sensitive alarm analysis. A CCD-camera records the behaviour of the daphnia, which are kept in a chamber fed with sample water (0.5-2 l/h). The live images are evaluated by the internal PC and investigated for changes in the swimming...
