Benchmark D1034-28 Prefilled 5.0ml tubes, Stainless Steel beads, 2.8mm Acid Washed, 50pk (for D1036 and D2400 only)

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

VACUUBRAND VACUU-PURE 10 Screw Pump Ultimate Vacuum 0.005 mbar (0.0038 Torr) Maximum Pumping Speed  (more)5.9 CFM Inlet/Outlet Connection Small Flange KF DN 25 Features - 10-3 mbar vacuum range - 100% oil-free - No abrasion - No wear parts The dry screw pump VACUU-PURE 10 reliably delivers the benefits of oil-free vacuum technology in the pressure range down to 10-3 mbar. VACUU-PURE 10 combines three important benefits for the user: 100% oil-free, no abrasion, and no wear parts. VACUU-PURE 10 is ideal for clean processes which require a dry and hydrocarbon-free vacuum. The spindles of the screw pump run contact-free and are thus free of abrasion and wear. The screw pump is especially designed for processes in the vacuum range down to 10-3 mbar, however unlike other fine vacuum technologies it can be used across the entire pressure range from atmospheric pressure to its ultimate vacuum. The evacuation of even larger systems from atmospheric pressure down to the 10-3 mbar vacuum range can be done without changing the vacuum pump. VACUU·PURE easily handles high levels of vapor accumulation through its extraordinary condensate compatibility. Thanks to this capability, a gas ballast is unnecessary, avoiding associated disadvantages like the reduction in pumping speed and an increase in noise levels. The integrated regeneration mode enables rapid drying of the pump at the end of the process. This allows sample throughput to be increased significantly as compared to other pump technologies. INCLUDED: The VACUUBRAND VACUU-PURE 10 Screw Pump includes: - 2 x Centering Rings - 2 x Clamping Rings - Power Cord - Operator's Manual - Manufacturer's Documentation - 2 Year Manufacturer's Warranty

VACUUBRAND PC 3002 VARIO Select Chemistry Pumping Unit Ultimate Vacuum 7 mbar Max. pumping speed a (more)t 60 Hz 1.65 cfm Number of Heads/Stages 2/2 Features - VACUU·SELECT vacuum controller with graphical user interface and predefined applications simplifies work in the laboratory - Automatic boiling point detection and adjustment of the vacuum for short process times - Compact and efficient, good ultimate vacuum even with open gas ballast valve - Very quiet, low-vibration operation and extra long service intervals - Excellent environmental compatibility through low energy consumption and efficient solvent recovery The PC 3002 VARIO select pumping unit precisely controls the vacuum level in order to achieve unparalleled process control. This two stage MZ 2C VARIO pump at the core of the PC 3002 VARIO is suitable for work with most common solvents. The integrated VACUU·SELECT controller provides an easy-to-use, application based interface that covers all common lab applications. The VACUU·SELECT controller has you covered. Use manual set-point-control for simple processes, run fully automated distillations, or create your own application with simple drag-and-drop editing. For solvent evaporation, the VACUU·SELECT controller detects the boiling point and automatically adjusts the vacuum process as necessary. The application, desired vacuum, and other parameters can also be combined or controlled individually. The pump runs only as fast as necessary due to the VARIO control. This extends the maintenance intervals and makes the pumping unit whisper-quiet. The inlet separator, made of glass with protective coating, prevents particles and liquid droplets from entering the pump. The exhaust vapor condenser provides nearly 100% recovery of solvents for economical recycling and environmental protection. Typical applications are all evaporation processes. Evaporation processes can be run fully automatically and with short process times and high sensitivity at the same time. The VARIO® control ensures high process reliability through prevention of superheating or foaming. The control allows for automatic vacuum level adaptation and is self-adapting to changing process parameters at any time. The VACUU·BUS® interface facilitates an user-friendly configuration of even complex vacuum installations.INCLUDED: The VACUUBRAND PC 3002 VARIO Select Chemistry Pumping Unit includes: - Power Cord - Operator's Manual - Manufacturer's Documentation - 2 Year Manufacturer's Warranty
