VACUUBRAND ME 16 NT Diaphragm Pump Ultimate Vacuum 70 mbar Max. pumping speed at 60 Hz 9.6 cfm Num (more)ber of Heads/Stages 8/1 Features - Contamination-free pumping and evacuation - High flow rate even near ultimate vacuum - Whisper quiet - Very low vibration - Exceptionally long diaphragm life and maintenance-free drive system for low lifetime costs Diaphragm pumps are an excellent solution for continuous, oil-free evacuation and pumping of gases. The one-stage design provides the advantageous combination of high pumping speed and low ultimate vacuum down to 70 mbar. All parts in contact with pumped media are made of aluminum and selected plastics allowing a wide range of applications for non-corrosive gases. The highly flexible, fabric-reinforced double diaphragms made of FKM are ideal for extended operating life. These pumps are particularly powerful and offer large volume flow. The eight-cylinder pump ME 16 NT features exceptionally high pumping speed, low vibration and a very compact design with smooth and easy-to-clean surfaces. Large one-stage diaphragm pumps are an excellent choice for continuous, oil-free pumping of large amounts of gases. Typical applications are vacuum ovens and in general evacuation and pumping of non-corrosive gases. They are also excellent for very fast evacuations down to modest vacuum levels.INCLUDED: The VACUUBRAND ME 16 NT Diaphragm Pump includes: - Power Cord - Operator's Manual - Manufacturer's Documentation - 2 Year Manufacturer's Warranty

Edwards Silencer for XDS35i Dry Scroll PumpFeatures - Compact design combines both filtration effici (more)ency and noise reduction - Integrated inlet diffuser optimizes sound attenuation - Multi-stage noise reducing features including final stage sound absorbent insert - Tubular silencing design - tube is positions to maximize attenuation and air flow while minimizing pressure drop - Patented high grade element with built-in butterfly gasket seal which creates positive seal between housing hemispheres and a new seal with each element - Seamless drawn housings - no welds to rust or vibrate apart - Durable carbon steel construction with black powder coated finish - Ability to mount vertically or horizontally The Edwards Silencer for XDS35i Dry Scroll Pump has two main functions: to reduce exhaust noise during pump down and gas ballast operation as well as to collect and retain tip seal dust as the pump is operated. Exhaust gases exit the exhaust port when the pump is being used to evacuate a process chamber, or when the gas ballast control is being used, or both. The noise level when pumping down rises as the throughput increases and the silencer is used to reduce this noise level. The outer can is made of pressed steel and is split to allow access to the filter elements. The filter element housing is made from Santoprene thermoplastic elastomer. The element itself is polyester. The foam block is manufactured from filter foam. INCLUDED: The Edwards Silencer for XDS35i Dry Scroll Pump includes: - NW25 Clamp - Centring Ring - Manufacturer's Documentation - 1 Year Manufacturer's Warranty

Edwards nXDS20iC Dry Scroll PumpFeatures - Bearing shield ensures separation between process gases a (more)nd bearing lubrication to ensure clean vacuum and no possibility of contamination. - 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. - Enhanced versions offer up to 20% lower peak power requirements during initial pump down. The nXDS allows a wide range of control and communication options The nXDS comes as standard with a manual, easy to use, gas ballast port A perfect companion for your turbomolecular pump With exceptional pumping capability, ultimate vacuum performance and state-of-the-art design features Edwards nXDS is the best performing pump in its class.nXDS improves on legacy XDS pumps by offering increased pumping speeds, combined with lower ultimate pressures, lower power consumption and lower noise - up to 20 times quieter than other pumps. Gas ballast allows for pumping of condensable vapours including, water, solvents, dilute acids and bases. nXDS pumps also feature the latest in tip seal technology giving significantly longer life between tip seal changes. Integrated inverter drive with auto sensing voltage input delivers optimised pumping performance globally. The Edwards nXDS20iC features Chemraz internal valves and stainlesssteel fittings for extra protection from the pumped media. The ‘C’ series isbetter designed for more aggressive applications as opposed to the standardseries.

Spectra Physics Mai Tai HR067 Laser and J80-8SS-28K Power Unit This system was removed from a labora (more)tory where it was surplus to requirements. The system is in very good cosmetic condition. The laser power supply powered on with cooling fans running, the display screen shows successful self-tests, and system details are displayed. However, according to the previous owner, "The FLIM card works but the multiphoton laser doesn't. At last inspection it would required £30K to repair the laser."  Therefore, no further testing was carried out, and it is listed as Spares/Repair. Includes: - Spectra Physics Mai Tai (Serial No. 3133, Year: 2007) - Spectra Physics Laser Power Unit (Part No. J80-8SS-28K-08, Serial No. 130906, Year: 2006)
