VACUUBRAND PC 3003 VARIO Select Chemistry Pumping Unit Ultimate Vacuum 1.5 mbar (1.12 Torr) Maximum (more) Pumping Speed 1.65 CFM at 60Hz Number of Heads/Stages 4/4 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 - Ideal for evaporation of high-boiling solvents even at low temperatures - Extraordinary diaphragm life for minimum operational and servicing costs - Excellent environmental compatibility through low energy consumption and efficient solvent recovery The PC 3003 VARIO select pumping unit precisely controls the vacuum level in order to achieve unparalleled process control. With its high pumping speed and deep ultimate vacuum, this pump is suitable for demanding applications with high boiling point solvents in low temperature conditions. 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 continuously detects the boiling point and automatically adjusts the vacuum process as necessary. And the VARIO control algorithm maintains the desired vacuum level without running the motor faster than necessary. This prevents bumping and foaming, makes the pump whisper quiet, and extends maintenance intervals. The inlet separator, made of glass with a robust protective coating, prevents particles and liquid droplets from entering the pump, preventing damage and extending pump life. And the exhaust vapor condenser allows for nearly complete recovery of solvents when used with a chilled water line or recirculating chiller for economical recycling and environmental protection. Typical applications are all evaporation processes. They can be run fully automatically by the integrated vacuum controller CVC 3000 resulting in both shorter process times and extra sensitivity at the same time. The excellent ultimate vacuum allows even high boiling solvents to evaporate at low temperatures. The VARIO® control ensures high process reliability through prevention of superheating or foaming. It detects boiling pressures of solvents fully automatically and adapts continuously the vacuum conditions to changing process parameters. All this without any need of parameter input or the use of a solvent library. In many other applications - like in local vacuum networks - the VARIO® control offers a significant advantage by supplying always the appropriate pumping speed. The VACUU·BUS® interface facilitates an user-friendly configuration of even complex vacuum installations.INCLUDED: The VACUUBRAND PC 3003 VARIO Select Chemistry Pumping Unit includes: - Power Cord - Operator's Manual - Manufacturer's Documentation - 2 Year Manufacturer's Warranty

KNF IP65 UFEM 1.10 KT.18RCP2 Liquid Pump KNF SIMDOS diaphragm pumps offer a variety of options to su (more)it most laboratory liquid metering and dosing needs. The UFEM 1.10 FT.18RCP2 version has a liquid transfer flow rate of 1 – 100 mL/min and discreet dosing volumes of 1 – 999 mL. It is constructed with the following chemically-resistant fluoropolymer flow path materials: PTFE head, PTFE covered diaphragm, and FFKM valves. The easy-to-read display combined with a touch control knob makes programming and access of all functions very intuitive. Besides onboard manual control, this pump offers analog control, start/stop and reset/prime TTL logic control, output signal fault alarm, and RS 232 PC control. A RC control interface cable and RS 232 cable with D-Sub 9 connector are included. A foot switch for start and stop impulses is available. All SIMDOS pumps are simple and intuitive to operate, compact, and quiet, making them a welcome addition to any business or academic lab. They are effective against pressures of up to 85 psig and transfer viscous media up to 500 centistokes (reduces flow rate above 150 cSt). The integrated software permits the transfer parameters to be modified for a range of different viscosities at the touch of a button. With a durable and IP65 splash-proof design, these pumps are maintenance free, and provide trouble-free ±2% accuracy and ±1% repeatability performance. SIMDOS 10 pumps are self-priming up to 9.8 feet of water, and can run dry indefinitely without damage. Also, unlike peristaltic pumps, there are no troublesome tubing to break or fatigue. INCLUDED: The KNF IP65 UFEM 1.10 KT.18RCP2 Liquid Pump includes: - Power Cord - Operator's Guide - Manufacturer's Documentation - 1 Year Manufacturer's Warranty

Edwards XDS46iC Dry Scroll PumpFeatures - Peak pumping speed of 23.5 CFM - Ultimate vacuum of 0.05 m (more)bar (0.04 Torr) - Bearing shield ensures separation between process gases and bearing lubrication to ensure a clean vacuum and no possibility of contamination to lubrication from process gases, which prolongs bearing life - Axial air gap motor reduces overall pump size and gives low power and noise - Smart motor drive means consistent performance globally, pump overload protection and remote start/stop capability - High flow gas ballast feature allows pumping of vapours including water vapour at up to 240 gh-1 - Simple single-sided scroll design allows maintenance to be done in minutes for low cost of ownership and maximum up-time - Fitted with Chemraz internal valve pads and stainless steel exhaust port for increased corrosion resistance XDS scroll pumps have become industry standard when dry pumping is essential, proving to be a robust and clean vacuum pump solution in a range of applications and processes. The XDS35i pump has an innovative bearing shield that isolates the vacuum environment from all forms of lubricant, making it not only lubricant-free but hermetically sealed. XDS35iNGB variant has had the gas ballast feature removed for applications such as rare gas recirculation and gas recovery. The XDS46i shares many of the same features of the XDS35i but with a peak speed of 40 m3h-1. The pump has been optimised for maximum pumping speed at inlet pressures between 1 mbar and 10 mbar, making it ideally suited for LCMS and ICPMS applications requiring higher pumping speeds. This C variant has been modified so that it is more suitable for use on vapour handling processes and may be used in some applications using corrosive substances. This C version is fitted with Chemraz® internal valve pads and stainless steel exhaust port. INCLUDED: The Edwards XDS46iC Dry Scroll Pump includes: - Power Cord - Operator's Manual - 1 Year Manufacturer's Warranty
