Clamps for oxygen determination bottles acc. to Winkler

Winkler pattern. Soda-lime glass.For determination of dissolved oxygen in water. The measured capacity is specified to ± 0,01ml. With white labelling area. Solid, bevelled glass stopper, secured with an accessory spring clip. Each bottle is adjusted to the relevant stopper. Stoppers and bottles are therefore not interchangeable. Each bottle and its stopper is marked with a unique, matching identification number.

The incubators from Lovibond® are designed for continuous tempering for different applications, mainly for the determination of BOD, the storage of wastewater samples, and the determination of enzymatic activity. The temperature range is +2°C up to +40°C and can be regulated in steps of 0,1°C. Temperature tolerance is defined with +/- 1°C respectively +/- 0,5°C (at 20°C). Low engergy consumption due to reinforced isolation. The interior of the cabinets is equipped with sockets for connecting stirrers. Illuminated LED display with actual / setpoint display.Temperature range 2 °C to 40 °C, continuously adjustable in steps of 0.1 °CLow power consumptionIlluminated LED display of preset and current temperaturesWith natural refrigerant R600aIdeal for BOD determination at 20 °CPower sockets inside the incubatorThe incubators from Lovibond® are designed for continuous tempering for different applications, mainly for the determination of BOD, the storage of wastewater samples, and the determination of enzymatic activity.

BOD measurement is an important measurement of the effects of domestic and industrial waste water on sewage plants and outflow points. The sensor system BD 600 is a 6 sample system that allows precise measurements of BOD based on the manometric principle. Manometric respirometers relate oxygen uptake to the change in pressure caused by oxygen consumption while maintaining a constant volume. Due to the modern integral pressure sensors, it is not necessary to use mercury for the measurements. The BOD values are stored automatically in the sensor memory at regular intervals and can be called up on the large-format display at any time without the need for time-consuming conversion using factors. This means that test series that end on a Sunday can be evaluated during the following week without any problem. Measurement series can be stored on USB stick/ SD card or transferred via USB cable to evaluate the data on a computer. The measurement period is user-selectable between 1 and 28 days to suit the application. While short measurement periods are useful for scientific applications, standard BOD measurements typically extend over a period of 5 days - and manometric determination of OECD, for example, generally takes place over a period of 28 days.Scope of supply:BD 600, complete unit with 6 or 12* sensor heads and control unit with batteriesPower supply unit incl.

These Stirring platforms have been specially developed for BOD measurement with the OxiTop® system. Software-controlled speed regulation prevents the magnetic stirrer bar from getting caught or wobbling. The speed is selected so that an optimal gas exchange with the sample takes place. The stirrer is maintenance-free and non-wearing as it contains no moving parts.The IS 6-Var model has been specially developed for use with large measuring vessels and has space for 6 measuring vessels. Its outer dimensions are identical to those of the IS 12. Speed 180 to 450 rpm.

The special bottle neck of the Karlsruhe bottles absorbs the water which is displaced by the stopper of the electrode. This construction guarantees clean working and ensures at the same time that the test results are not adulterated by unwanted entry of oxygen into the samples.
