Equipment Set “Environment Explorer” Strong and versatile set of equipment for taking water and plankton samples, for catching flies, beetles, suspended particles, aquatic insects etc. or for collecting small creatures in soil from the beds of watercourses. The key component is a telescopic pole to which the various nets and collecting vessels can be attached. […]

Compact analysis set in carry-case for reliable determination of key parameters for water in scientific lessons which do not require detailed prior knowledge. The case contains all the necessary reagents and accessories. It can be used to determine the following parameters for natural water: ammonium-content, nitrate-content, nitrite-content, phosphate-content, pH value and overall hardness. There are […]

Separate test kits for chemical analysis of water samples without the need for extra apparatus or previous chemical knowledge. The VISOCOLOR ® card color templates are keyed to the original colors of freshly prepared standard solutions, thus ensuring fine resolution, precision and reproducibility of the measurement results. Instructions in German, English, French, Italian, Spanish, Dutch, […]

The measurement chamber for earthworm experiments is used in neurophysiological experiments on intact worms. This involves stimulation of the worm by electrical or tactile means and measurement of its action potential. Worms remain uninjured and can be returned to their habitat after completion of the experiment. A cover with holes drilled in it allows worms […]

The bio-measurement interface is for measurement and control in electrophysiological experiments with the bio-amplifi er. It operates in conjunction with a computer via a serial USB interface. Driver and measurement software are included with the equipment. There is also a built-in fl oating, software-controlled pulse generator, which acts as a stimulus generator in conjunction with […]

This analysis set can be used to reliably identify important soil parameters without prior knowledge of chemistry. The case contains all the necessary reagents, equipment and accessories. It can be used to identify the concentrations of the following substances in the soil: nitrate, nitrite, ammonium, phosphate and potassium. It is also possible to determine soil […]

Two-channel amplifi er for electro-physiological experiments. The ampli fi ed signals from both channels can be displayed on a storage oscilloscope or with the help of the Bio-measurement interface connected to a computer. Gain and frequency response are dependent on the selected experiment: action and muscle potentials in live earthworms (Worm), electro-retinograms (ERG), electrocardiograms (ECG), […]
