Vacuum Solutions for Filtration and SPE

Fluid movement applications, such as filtration and solid phase extraction typically don’t require deep vacuum levels or high flow rates. Normally, these applications are best served by VACUUBRAND^®’s ME2C and ME4C NT. Users seeking additional capability or users with special circumstances, however, may want to consider VACUUBRAND^®’s MZ2C NT + 2AK or MD1C + AK + EK pumps with integrated solvent recovery.

When choosing the pump for your filtration or solid phase extraction application, consider the following factors:

How much vacuum do I need?
Vacuum filtration and solid phase extraction typically require just enough vacuum depth to generate a pressure differential between the receiving vessel and atmospheric pressure. These applications do not usually require control unless the vacuum level is too low and may cause filtrate boiling.

The ME2C vacuum pump is an excellent selection for most fluid movement applications. It is a simple, compact, stand alone pump with sufficient vacuum and flow to perform effective vacuum filtration or solid phase extraction and is powerful enough to support up to three simultaneous applications.

How much flow do I need?
Labs running more than three simultaneous filtration applications may require a pump with higher flow rates to maintain sufficient vacuum at all workstations.
The ME4C NT vacuum pump is an excellent pump for these circumstances. Like the ME2C, it is a simple, compact stand alone pump. However, its higher flow rate ensures better results and faster process times in large-scale filtration and solid phase extraction labs.

Do I need solvent recovery?
During normal filtration and solid phase extraction applications, filtrates under vacuum in the receiving vessel can evaporate and pass through the pump into the lab, or contaminate the pump itself. This problem can be minimized by a vacuum pump with integrated solvent recovery to collect those vapors, such as the MZ2C NT +2AK or the MD1C+AK+EK.

The solvent recovery and higher performance of these pumps also allows them to support a broader range of applications. They are an excellent choice for labs seeking to support multiple applications with only one pump.
