Tekmar Dohrmann Velocity XPT Purge and trap-cover
Tekmar Dohrmann Velocity XPT Purge and trap

For sale: Tekmar Dohrmann Velocity XPT Purge and trap Condition: never used Including: installation  (more)kit + test reports from manufacturer     We are not a agent/reseller. All products on our website are in stock and can be delivered with installation by our own service engineers. All systems are delivered with warranty! ​Velocity XPT is more than a next-generation Purge and Trap system, it’s a revolutionary leap in technology. Advancements in Velocity XPT ensure the highest throughput with the least amount of downtime. From cutting sample cycle time nearly in half, to built-in intelligent diagnostics, Velocity XPT is the most productive Purge and Trap available today. With the Velocity XPT, you increase the sample throughput up to 100%. This nearly double sample throughput and increases the profitability of your VOC lab without the cost of an additional GC system. Patent-pending Accelerated Purge and Trap technology lets you independently control the flow rate during all modes, greatly reducing dry purge and bake times. Velocity XPT also provides a 25% reduction in trap cool down time after bake mode. Forward Focusing Chamber:  This patent-pending technology provides the highest resolution chromatography and superior peak shape for early eluting gases. By placing an expansion chamber after the trap during the desorption modes, analytes are focused into a tight band. When analytes are tightly focused prior to desorption into the GC, dramatic improvements in chromatography resolution are evident. The FFC also efficiently desorbs which greatly reduces carryover from run to run. Exceptional Inertness: Silcosteel tubing and Silcosteel-treated fittings throughout the sample pathway prevent loss of active, polar, and high-boiling compounds, and also resists corrosion. With the simple setup and accurate control, you save time by entering all parameters electronically with Electronic Flow Control where flow and pressure parameters remain precisely the same and are constantly monitored for accurate and reproducible results. Automatic Leak Check, Electronic Pressure Monitor: With intelligent diagnostics, Velocity XPT quickly and simply checks itself for leaks. If a leak is detected, system diagnostics help you isolate and pinpoint leaks. The Electronic Pressure Monitor uses a pre-set over pressure limit to identify potential pressure build ups and will shut itself down before damage can occur. The Guardian Foam Sensor option is a set of built-in photodiode-based sensors. If foam or liquid is detected at the top of the glassware, purge gas shuts down, the vent valve closes, and the sample drains. Guardian can be configured to automatically add an anti-foaming agent to the sample, allowing purge to continue and without re-running the sample.

Varian DS 102 Two-stage Rotary Vane Pump SQ 396 SP + Oil Mist Eliminator KF 25-cover
Varian DS 102 Two-stage Rotary Vane Pump SQ 396 SP + Oil Mist Eliminator KF 25

Manufacturer: Varian Model: DS 102 Two-stage Rotary Vane Pump + Oil Mist Eliminator KF 25 949-9395 s (more)erie S/N: 219579 Description: Thanks to a very simple and highly reliable design, this field proven DS Series rotary vane pump provides excellent vacuum performance. The quality and manufacturing standards ensure that the DS rotary vane pumps provide high pumping stability for light gases, low noise, minimal oil backstreaming, and a long operating life. The pump’s two-stage design allows for low operating temperature, minimal backstreaming at low pressure and good pumping efficiency and gas ballast. It delivers a pumping speed of max. 114 liters per minute, low noise and a long operating life. It conforms to European Union directives (CE) and Restriction of Hazardous Substances (RoHS) requirements, and it is also UL and Canadian Standards Authority (CSA) approved. Oil Mist Eliminator KF 25 949-9395 serie is assembled at the outlet of the rotary pump and the main purpose is to purify the exhaust gases from oil mists. The use is advised for pumps which have to work for a long time at intake pressures exceeding 10 mbar, or with the ballasting tap open. Applications: - Analytical Instruments:Dual Stage Rotary Vane Pumps are practically the only primary vacuum pumps used on GC-MS and MALDI-TOF Instruments:GC-MS typically uses this small pump - the pump is needed to rough the system and back the high vacuum Turbo or Diffusion pump. MALDI-TOF depending on system size, uses the DS102 as roughing or interface pump.- Leak Detection:DS102 is typically used to back the Helium Mass Spectrometer Turbo or Diffusion pump.- Industrial Vacuum Processes:Vacuum coatings, Metallurgy Vacuum Furnaces, Lamps and TV Tube manufacture, Sterilizers, Freeze Dryers, Glove Boxes, High Speed Centrifuges, and Flywheels (for energy storage) represent the main Industrial applications for Dual Stage Rotary Vane pump. - High Energy Physics and Research Laboratories:In these applications the Rotary Vane pumps are mainly used in combination with Turbo pumps. The combination is typically used to rough and pump High Vacuum experimental chambers or to start Ion Pumps in ultra high vacuum systems.Features: - Dual Stage Pump:The two stage design allows low 10-3 mbar operation, low operating temperature, minimal backstreaming at low pressure, good pumping efficiency and gas ballast in the high 10-3 mbar region.- Forced Oil Circulation:The dedicated oil circulation gear pump ensures efficient and reliable lubrication of the pump from atmospheric pressure throughout the entire vacuum operating range.- Built-in Oil Shield:This feature minimizes the oil mist at the pump exhaust. Apart from drastically reducing the oil consumption over long periods of operation, this results in a reduction of air pollution limiting the impact on the environment.

BOD Sensor Velp analysis system-cover
BOD Sensor Velp analysis system

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.
