VACUUBRAND MD 1 Diaphragm Pump Ultimate Vacuum 1.5 mbar (1.1 Torr) Maximum Pumping Speed 0.82 CFM a (more)t 60Hz Number of Heads/Stages 4/3 Features - Contamination-free pumping and evacuation - High flow rate even near ultimate vacuum - Excellent ultimate vacuum - Whisper quiet and ultra-low vibration - Proven long diaphragm life, maintenance-free drive system The MD 1 diaphragm pump is an excellent choice for oil-free evacuation and pumping of non-corrosive gases down to 1.5 mbar ultimate vacuum. The three-stage design with precisely guided flat diaphragms provides outstanding pumping speed even close to the ultimate vacuum, especially when compared with similarly rated two-stage diaphragm pumps. The MD 1 is an ultra-low vibration pump with very long diaphragm lilfetime and stable ultimate vacuum documented with years of testing. With a flow path consisting of aluminum and selected plastics (diaphragms and valves made of PTFE/FKM and FKM, respectively) the pumps are suitable for a wide range of applications with non-corrosive gases. The MD 1 is an excellent choice for continuous, oil-free evacuation and pumping of non-aggressive gases. It is suitable for high vacuum requirements at modest gas flow as often needed in physics and analytics. The pump is exceptionally quiet and reliable with long diaphragm and valve lifetimes. With its low ultimate vacuum and compact dimensions the MD 1 is widely used as replacement of rotary vane pumps. Typical applications are exhaust gas analysis, for degassing of small amounts of viscous media and in particular as backing pump for compact turbomolecular drag pumps. Back diffusion of oil or even oil back flow, e.g., into a high vacuum chamber is excluded due to its oil-free operation. For equipment manufacturers customized versions are available.INCLUDED: The VACUUBRAND MD 1 Diaphragm Pump includes: - Power Cord - Operator's Manual - Manufacturer's Documentation - 2 Year Manufacturer's Warranty

Labconco 794801300 FreeZone Stoppering Tray Dryer with 6-Port Manifold and IsolationValve 115V, 60Hz

Labconco FreeZone Stoppering Tray Dryer with 6-Port Manifold and IsolationValve FreeZone Stoppering (more) Tray Dryers lyophilize moderate to largeloads of vials or serum bottles and stopper them under vacuum. They offertemperature control from -40 to +40C. Options include a 6-port manifold,isolation valve and sample trays. A pneumatic mechanism stoppers containers undervacuum on three large adjustable processing shelves, 16.5” x 12” each. AnHCFC/CFC-free refrigeration system and electric heater cool and heat fluidmedium that is circulated through the shelves to maintain shelf temperatureswithin ±1C. Lyo-Works™ OS lets the user set up to 30 programs, with up to 16steps each; record, chart and store data; and receive email alerts. The traydryer connects to a FreeZone Console Freeze Dryer that provides a real timedisplay of the tray dryer’s parameters on a large capacitive touch screen. Features Three 16.5 x 12 in. temperature-controlled (±1C), adjustable shelves with sample temperature sensors Chamber pre-freezes samples to save time and money by eliminating need for separate freezer and product transfer Up to 594 sq. inches of shelf space Circulating fluid in shelves ranges from -40 and +40C 1/8 in. OD backfill port introduces sterile air or inert gas from outside source to chamber, protecting samples from atmospheric moisture and contaminants Lyo-Works™ OS provides real time display of freeze dryer and tray dryer parameters on 5 in. full color, capacitive touch screen on connected FreeZone 6, 12, or 18L Freeze Dryer (sold separately) Microprocessor-based controller allows up to 30 different temperature programs to be stored and repeated, each using up to 16 different steps Display provides navigation to manual or program mode, probe temperatures, vacuum in mBar, Torr or Pa, step of program in progress, time remaining in present step, and end of program, as well as alarms Optional 6-Port Tray Dryer Manifold accommodates either 1/2 in. or 3/4 in. flask adapters and connect to flasks and other glassware Optional built-in isolation valve separates Stoppering Tray Dryer from freeze dryer to shorten time necessary to reestablish working vacuum levels and to provide means for determining end point Freeze dryer, vacuum pump with displacement of at least 163L/minute, and freeze dry glassware (if not bulk freeze drying) are required (not included) INCLUDED: The Labconco 794801300 FreeZone Stoppering Tray Dryer with 6-Port Manifold and IsolationValve 115V, 60Hz includes: - Sample Temp Sensor x 3 - Communication Cable - Power Cord - Operator's Guide - Manufacturer's Documentation - 1 Year Manufacturer's Warranty
