The Labconco CentriVap Benchtop Vacuum Concentrator and CentriVap Cold Trap System is designed to rapidly concentrate multiple small samples using centrifugal force, vacuum and heat. Sample sizes range from a few microliters up to 25 milliliters.
The CentriVap Cold Trap collects evaporated liquid from the CentriVap Vacuum Concentrator, protecting the vacuum pump from corrosion. The trap may also be used in other laboratory applications such as freeze drying and desiccation.
ADDITIONAL INFORMATION
Features of the CentriVap Vacuum Concentrator:
Microprocessor-controlled centrifugal motion up to 1725 RPM eliminates bumping and foaming common when applying vacuum during evaporation and maximizes recovery of trace solutes.
Quick-Stop™ System. Once run time has expired or the RUN/STOP button is pressed, within seconds the vacuum pump stops, the valve opens to bleed air into the chamber, and the rotor stops.
Automatic vacuum release valve prevents loss of sample by releasing the vacuum before the rotor stops and during power failures.
Lid latch with safety sensor locks the lid in place when the rotor is turning and prevents start up when the lid is open.
Built-in vacuum delay prevents bumping by allowing the rotor to achieve speed before applying vacuum.
Corrosion-resistant sample chamber accommodates accessory rotors for a wide variety of sample tubes.
Large phenol-free lid seal ensures good vacuum without potential for phenol contamination.
Microprocessor-controlled 300-watt heater speeds evaporation by supplying a controlled amount of heat from OFF up to a maximum of 100° C in one degree increments.
Three Quick-Start™ Buttons store one user-set program each.
Easy-to-read LCD display prompts the user to set program parameters and displays program number, actual and set point temperatures, heat time remaining, run time remaining, and if Heat Boost™ is activated.
Heat and run times are set separately, each from 1 to 999 minutes, so that heat may be programmed to shut down sooner than the run to protect heat sensitive samples from excessive heat exposure after the solvent has evaporated.
PREHEAT button activates the heater to begin elevating to set point temperature.
Memory stores 9 user-set programs with parameters of temperature, heat time and run time.
Audible alarm signals completion of set point run time.
Electrical receptacle allows connection of accessory vacuum pump so that the pump may be activated from control panel.
ETL listed for 115 Volts.
Features of the Labconco CentriVap Cold Trap:
Four liter stainless steel collector holds up to four liters of liquid.
Ready indicator illuminates when the collector coil reaches operating temperature.
Acrylic lid has two Quick-Disconnect fittings for 1/2" ID hose for connecting the Cold Trap and CentriVap.
CFC-free refrigeration system has a high capacity 1/4 hp compressor to lower cold trap temperature to -55° C in less than 15 minutes and accelerates start up procedures.
Collector drain speeds clean up and eliminate need for glass insert with non-corrosives.
