ROTARY EVAPORATION/DISTILLATION The most important considerations when choosing a rotary evaporator All KNF pumps are chemical-resistant, offer a high vapor compatibility and feature a gas ballast. There are three key parameters to consider when selecting an appropriate vacuum system. Firstly, the performance of the vacuum system is dependent on the volume of the evaporating flask used. The larger the volume, the higher the flow rate required. Beyond this, it is necessary to consider the ultimate vacuum required for the evaporation process, as well as whether or not a remote control is required....

The relevance of the right vacuum level... All KNF pumps are chemical-resistant and have a high vapor compatibility. The efficiency of vacuum filtration can be affected by a number of different factors, including the porosity of the filter, the viscosity of the liquid to be filtered and the type of particle to be removed. When choosing a vacuum pump, it is important to consider the volume of your flask and the number of filtration units (here referred to as “funnels”). A vacuum that is too weak will cause the process to take more time, while a vacuum that is too strong can lead to the filter...

SPE/SOLID PHASE EXTRACTION An ideal solution from KNF SPE/SOLID-PHASE EXTRACTION Solid-phase extraction is a common method of sample preparation where compounds are dissolved in a liquid and separated according to their chemical and physical properties. A vacuum pump can be used to speed up this physical extraction process. All KNF pumps are chemical-resistant and have a high vapor compatibility. When choosing a vacuum pump for solid-phase extraction, it is important to select a pump with both an appropriate flow rate and a vacuum level suited to the application. The N 816.3 KT.18 diaphragm vacuum...

Viscosity and container volume All KNF pumps are chemical-resistant and have a high vapor compatibility. The viscosity of the solvent and the container volume or capacity play an important role in both dessication and vacuum degassing. Viscous liquids such as gels, creams and synthetic resins require a higher ultimate vacuum than thin liquids. The larger the volume, the higher the flow rate required to ensure a fast evacuation of the system. Solvent Low viscosity fluid Diaphragm Vacuum Pump Solvent Viscous fluid Solvent Low viscosity fluid DESICCATION/ DEGASSING Flow rate: 16 l/min Ultimate vacuum:...
