The typical work flow for operating the Model L is shown below in Figure 1. The user begins bydetermining what type <strong>of</strong> separation they will be conducting with the Model L and then selectingan appropriate membrane filter. Once the desired membrane has been selected, the user mustthen configure the Model L for the membrane selected.Follow these guidelines to determine filtration type and membrane:Determine either the size or molecular weight <strong>of</strong> the particle to be separatedIdentify which type <strong>of</strong> filtration (MF, UF, or RO) will be required to perform the desiredseparation.Review specifications from membrane manufacturers to identify appropriate membrane.Pay close attention to the following:<strong>Operating</strong> limits <strong>of</strong> candidate membranes (pH, temperature range, maximum pressure).The maximum pressure (Pmax) <strong>of</strong> the membrane will determine how concentrated <strong>of</strong> a solutionyou can filter. The Model L has a Pmax <strong>of</strong> 1000 psi.11
