Combining top-notch and uncompromising quality with an affordable price the Labconco CentriVap Benchtop Centrifugal Concentrators and Systems Labconco Benchtop Centrifugal Concentrators Acrylic Lid 7810010/ 89004-916 can fulfill your laboratory needs while still offering a great value for the money. Product Category Description: Ideal for biology microbiology biochemistry pharmaceutical research and analytical chemistry laboratories centrifugal concentrators quickly process the evaporation of multiple small samples. Benchtop Vacuum Concentrators feature 30.5cm (12") dia. epoxy-coated aluminum chambers to accommodate a wide selection of high-capacity rotors. A microprocessor controls centrifugal motion to eliminate bumping and foaming during vacuum evaporation. The brushless motor has a maximum speed of 1725rpm. A large automatic vacuum release valve prevents loss of sample by quickly releasing the vacuum before the rotor stops. During startup a built-in vacuum delay prevents bumping by allowing the rotor to achieve set speed before applying vacuum. Up to nine user-set programs may be stored to define temperature heat time and run time. Program temperature and time may be altered while the program is being run. Timer may be set for 1 to 999 minutes. An easy-to-read LCD shows program number actual and set point temperatures heat time run time and a heat boost indicator. The control panel features three Quick-Start buttons that each store one user-set program. An audible alarm signals completion of set point run time. Microprocessor-controlled 300W heater speeds evaporation by supplying up to 100 C (212 F) of heat in 1 C increments. Optional heat boost warms the chamber with additional heat up to 100 C in 1 C increments. Heat and run times are set separately to protect heat-sensitive samples from excessive heat exposure after the solvent has evaporated. The lid features a large phenol-free seal and a safety sensor that prevents startup when the lid is open. Concentrators include a 1.3cm (1/2") O.D. aluminum hose fitting and a vacuum port with a 6.4mm (1/4") quick-disconnect fitting. An electrical receptacle on the back allows the vacuum pump (sold separately) to be powered and controlled via the control panel. Cold traps have CFC-free refrigeration systems with 1/4hp compressors that lower temperature to 55 C ( 67 F) in less than 20 minutes. The ultra-low cold traps have two compressors to lower temperature to 85 C ( 121 F) within 40 minutes. All traps feature an acrylic lid with two quick-disconnect fittings for 1.3cm (1/2") I.D. hose an LED temperature graph display and a 4L stainless steel collector that features a drain with a corrosion-resistant nylon valve. CentriVap aqueous acid and solvent systems include a benchtop concentrator cold trap 12 13mm rotor and vacuum tubing with six clamps. Aqueous systems also include a clear canister and moisture insert. Acid systems include an acid-resistant benchtop concentrator an acid-resistant 12 13mm rotor a clear canister an acid insert and a glass trap. Solvent systems feature glass lids and include a clear canister and solvent insert. Gel dryer systems include a gel dryer and a three-way valve. Vacuum pumps are sold separately. The CentriVap systems are also available as mobile units which encase the system components in a brushed stainless steel cabinet with 5.1cm (2") dia. hard rubber casters. The cabinets feature space for vacuum pumps (not included). Mobile systems are supplied with a 12 13mm rotor that holds a hundred 12x75mm or 13x75mm tubes sixty-four 12x95mm or 13x100mm tubes sixteen 12x55mm tubes or forty 1.5 or 2.0mL microcentrifuge tubes. Mobile systems also include a clear canister and solvent insert. The 115V 60Hz concentrators and all 60Hz cold traps and systems are ETL and ETLc listed. The 230V 50Hz concentrators and all 50Hz cold traps and systems are CE marked. Note: The 115V concentrator systems require a 20A dedicated circuit; the 115V mobile concentrator systems require a 20A circuit breaker. The 230V concentrator systems require a 10A dedicated circuit; the 230V mobile concentrator systems require a 10A circuit breaker. Ordering Information: All units include one-year manufacturer s warranty. Acid-resistant benchtop concentrators (89041-236 and 89041-238) feature a fluoropolymer resin-coated aluminum chamber. Other components in the vapor path are constructed of acid-resistant materials as well. The 115V mobile concentrators and cold traps are supplied with a 2m (6.5') three-wire power cord with a NEMA 5-15 plug; the 115V mobile systems are supplied with a 3m (10') three-wire power cord with a NEMA 5-20 plug. The 230V concentrators cold traps and mobile systems are supplied with a 2.4m (8') power cord with a NEMA 6-15 plug. Benchtop concentrators require cold traps and a vacuum pump; systems require a vacuum pump. For
