Water treatment equipment

BOD Sensor is an extremely reliable innovative solution for the determination of BOD, without the us (more)e of mercury. Easy to use, fast and simple. It screws directly onto the bottle containing the sample and a pressure transducer microprocessor transfers the BOD value directly to the display (in mg / l) and automatically stored in the BOD sensor (5 measurements at 24 hour intervals, offering the possibility of making the analysis even during the weekend). The BOD value can also be obtained directly from the display at any time, even after five days. Measurement is available on 4 different scales - 90ppm, 250, 600 and 999 BOD. For higher values, the measurement can be measured by diluting the sample. The BOD Sensor System 6 is a complete package for analyzing 6 samples simultaneously, consisting of a 6-position stirring base, BOD sensors, dark glass bottles, carbon dioxide absorption caps and magnetic stir bars. The BOD Sensor System 10 is a complete package for analyzing 10 samples simultaneously, consisting of a 10-position stirring base, BOD sensors, dark glass bottles, carbon dioxide absorption undercaps and magnetic stir bars. The stirring base has been designed to meet the user's needs, it is comfortable, guarantees a high quality stirring and the small footprint allows to accommodate up to 5 bases of 6 positions (30 samples) or 3 of 10 positions ( 30 samples) in a VELP incubator (FOC 200E). Determine the BOD value in 5 steps! To better analyze the BOD values ​​with the innovative VELP Scientifica systems, based on the respirometric technique, capable of providing highly reliable results, just 5 easy and simple steps are enough: 1. Add the magnetic stir bar to the dark glass bottle, add the sample and place the CO2 trap filled with the necessary reagents 2. Incubate everything 3. Screw in the sensor 4. Monitor the activity of microorganisms 5. Read the BOD value (ppm or mg / l), based on the change in pressure inside the bottle due to the activity of microorganisms Technical features: Sensor display: 3-digit LED display Bod measurement: mg/l (ppm) directly on the display BOD scales: 90, 250, 600, 999, 4000 ppm, Higher values after dilution Bottle volumes:  500 ml Data storage: BOD values at 24h intervals Sensor construction material: Technopolymer Power: BOD Sensor System 6 2 W; BOD Sensor System 10 2 W Sensor battery type: CR 2430 Power supply: BOD Sensor System 6 Sensors: 2x3V lithium batteries Stirring Station: 230V / 50-60Hz or 115V / 60Hz BOD Sensor System 10 Sensors: 2x3V lithium batteries Stirring Station: 230V / 50-60Hz or 115V / 60Hz

The KNAUER Online Degasser is a 2-channel for semi-preparative flow rates up to 50 ml/min. The degas (more)sing membrane is an innovative Teflon AF fluoropolymer which is more than 200x more gas permeable than regular Teflon and has excellent physical and chemical stability characteristics. Its high efficiency also allows for reduced internal chamber volumes– less than 7.7 ml per channel. For isocratic HPLC applications the 2 chambers of the semi-prep degasser can be connected in series for maximum degassing efficiency. For gradient applications, up to 2 eluents can be degassed simultaneously. For special applications, one degasser can also be used for multiple HPLC systems. The low dead volume makes reconditioning fast and minimizes solvent waste. Extremely low chamber volumes. Broad chemical compatibility is perfect for use in general HPLC applications Zero hysteresis even at higher flow rates No need to replace check valves or other parts even when under continuous operation Prevents air bubble spikes in the chromatogram Minimizes retention time fluctuations Minimizes gradient reproducibility problems Minimizes unwanted formation of chromophores which can disturb UV detection Minimizes unwanted oxidation or reduction which can disturb electrochemical detection Minimizes fluorescence quenching Technical Data: Dimensions: 85 x 165 x 315 mm (W x H x D) Weight: 2.5 kg Power Supply: 85 – 265 V, 47 – 63 Hz, 20 W Max. Flow Rate: up to 50 ml/min Number of Channels: 2 Degassing Method: gas permeation through Teflon AF amorphous fluoropolymer membrane Degassing Efficiency: < 0.5 ppm residual dissolved O2 at 1 ml/min Dead Volume: 7.7 ml Solvent Applicability: universal, except hydrochloric acid and halogenated hydrocarbons especially hexafluoro isopropanol (HFIP) Wetted Materials: PEEK, Tefzel, Teflon AF Vacuum Chamber: polypropylene and stainless steel
