The sample requires to be stirred so that the formation, development, and settlement of floc can be watched just as it would be in the fullscale treatment plant.The operator then performs a series of tests to compare the effects of different amounts of flocculation agents at different pH values to determine the right size floc.

Intuitive and Digital COD Analysis Thermoreactor ECO 16 ensures a simple and easy programming of time (from 1 to 199 minutes or continuous) and temperature (from ambient to 160 °C).Through the digital display, it is possible to monitor the test at any time, with the countdown constantly shown.The unit automatically shuts down when the analysis time expires, whilst safety is of primary importance, as demonstrated by the antisplash cover that protects the user and other samples and the several acoustic and visual signals that report unpleasant situations. Eco 16 has also the transparent test tube cover that offers a constant visual control.Safe and FastECO 16 COD Thermoreactor can be used with 14 small tubes of 16 mm and 2 x 22 mm. The thermoreaction in small test tubes minimizes reagent consumption and reduces the required space and equipment to one reactor block that works on several samples at the same time.Each test set-up is a self-contained disposable vial, which is inserted into a heating system, using small amounts of reagent and sample and so decreasing both the cost and the waste volume. ECO 16 is suitable for performing a short time COD analysis, in only 30 minutes with a high thermoreaction temperature (160 °C).

UDK 129 Kjeldahl Distillation UnitEntry-level Kjeldahl distillation unit for your analyses concerning different applications such as determining ammoniacal nitrogen, protein determination, nitrogen content (Kjeldahl or direct alkaline distillation), nitric nitrogen (after reduction/Devarda), phenols, volatile acids, cyanides and alcohol content.Entry-level Kjeldahl Distillation UnitThe Kjeldahl distillation unit UDK 129 runs automatically, after setting sodium hydroxide addition and distillation time using the LCD display in order to get reliable and accurate results. The high-precision pumps ensure constant accurate dosing of reagents and the cooling water is automatically stopped during pauses, thus cutting down on its consumption.UDK 129 includes many features that ensure efficient and reliable distillation, far beyond expectations of an ordinary entry level unit.The UDK 129 Distillation Unit ensures the highest safety standards to provide maximum protection to the operator: the use of an innovative system allows the insertion of the test tube in complete safety and the use of test tubes of various sizes.

-Since materials that can react with metal detectors (including core materials) are used, reduces the risk of contamination by foreign objects substances-Compliant product for food hygiene test

-This is a connector that takes the larger inner diameter compared with general resin connectors and reduces loss of the flow amount or pressure.-Excellent in pressure resistance and chemical resistance.-Complies with the food hygiene test that is specified in the Ministry of Health and Welfare Notification No. 201, 2006.

-Since materials that can react to metal detectors are used, reduces the risk of contamination by foreign objects substances.-More excellent in wear resistance than a polyethylene spatula-Compliant product for food hygiene test

SER 148 Series - Solvent ExtractorsSolvent extraction system suitable for the separation of a substance or a group of elements from solid and semi-solid samples according to the Randall technique.- The reliable solution for solvent extractionThe SER 148/3 and SER 148/6 can be used to separate a substance or a group of elements from solid and semi-solid samples according to the Randall technique (consisting of Immersion, washing and solvent Recovery).As for the automatic version SER 158, the main field of application is the determination of the content of soluble products such as fats, detergents, plasticizers and pesticides in food, animal feeds, detergents, rubber and plastic formulas, pharmaceutical products, soil.The SER 148 Series is a semi-automatic solution with no compromises on operator safety (IP55) and solvent consumption also guaranteeing a limited cost per analysis.Combined to HU6 Hydrolysis Unit, is possible to use the same crucibles to prevent any possible sample loss between the two units.- Randall Method, Faster ResultsPerform single or multiple solvent extractions with Randall method, an improvement of Soxhlet technique, as hot solvents are used to speed up the analysis. In fact, the fast solubilization made by hot solvent permits a considerable reduction of the extraction time (approx. 90 minutes).The extraction is made by immersion of the sample in the boiling solvent, followed by a rinsing phase with cold solvent.Maximum reproducibility is ensured, as well as a high recovery rate of the solvent used.SER Series can be used with a wide range of sample types and with a variety of solvents, for increased flexibility.

ARE Hot Plate Stirrer. Hot plate stirrer widely used in research and development, industrial and university laboratories worldwide. Easy to Use and to Control. The hot plate stirrer ARE offers an innovative low profile and attractive design for an outstanding comfort. Also, the inclination of the front panel has been carefully studied to facilitate use. The control panel is extremely intuitive. By turning the left knob of the hot plate stirrer it is possible to adjust the temperature (up to 370°C), whilst the right one controls the stirring speed (up to 1500 rpm). Aluminum alloy top plate ensures a great temperature homogeneity and optimum heat transfer across the entire surface. Maximum Protection Against Leakages - IP 42. The hot plate stirrer ARE ensures an excellent level of safety and protection for the user. The elevated control panel is easily accessible, is positioned at a safe distance from sources of heat and is protected against possible damage caused by liquid spills thanks to a dedicated run-off groove. The pressure die-cast structure is designed so that accidental liquid spills cannot reach the internal parts of the hot plate stirrer.

Cannot be used in solvent-based liquid.
