A cold trap condenses all those vapors into a solid or liquid state except for the permanent gases. The main function of the cold trap is to prevent contamination inside the vacuum applications. While conducting experiments, scientists want the container to sit airtight so that no vapor can evacuate.

CentriVap Centrifugal Vacuum Concentrators use a combination of centrifugal force, vacuum and heat to speed laboratory evaporation of multiple small samples. CentriVap Cold Traps protect your vacuum pump from corrosive chemicals.

The CentriVap Complete system combines a concentrator, cold trap, and a vacuum pump in one cabinet. As an integral part of the CentriVap Complete system, the cold trap can be used to trap moisture, vapors, and corrosive fumes as they evaporate from the samples.

In a vacuum concentrator, samples are held in a rotor that spins at 1700 RPM creating a centrifugal force. The centrifugal force prevents liquids from bumping out of the tube when vacuum is applied. Heat is applied indirectly through the walls of the vacuum chamber.

Used in proteomics, genomics, cell biology, microbiology, and drug development, a vacuum centrifuge concentrator uses a vacuum, centrifugal force, and sometimes heat or gas blow down to evaporate liquid and concentrate DNA, RNA, nucleotides, and other proteins for further use or study. …

The Importance of the Evaporator Coil The main job of the evaporator coil is to cool the refrigerant so that it can absorb the heat. As the fan blows air over the coil, the refrigerant becomes cold and turns into a vaporous state.

Cold Traps are offered in three temperature choices, -50°C, -85°C and -105°C. Choosing the correct Cold Trap temperature will optimize the trapping efficiency. It is important to select a cold trap that reaches temperature that is colder than your sample’s freezing point.

Cold Traps are offered in three temperature levels: -50°C, -85°C and -105°C. Choosing the correct Cold Trap temperature will optimize the moisture trapping efficiency. It is important to select a cold trap capable of reaching a temperature that is colder than your sample’s freezing point.

Evaporation and vapouration are two processes in which simultaneous heat and mass transfer process occurs resulting into separation of vapour from a solution. Evaporation and vapourization occur where molecules obtain enough energy to escape as vapour from a solution.

A rotary evaporator (also called as “rotavap” or “rotovap”) is a device used in labs for the efficient and gentle removal of solvents from samples by evaporation.

CentriVap Concentrators are also available as one component of CentriVap Concentration Systems. Let Scout lead you to the right laboratory hood or evaporation equipment for your application. These concentrators are designed to rapidly concentrate as many as 132 small samples using centrifugal force, vacuum and heat.

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.

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.

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.
