Performance envelope , biological

In the future this innovation in the testing of the performance of biological safety cabinetry will make it easier to evaluate cabinet performance when the cabinets are serviced and certified. The use of the cabinet performance envelope concept can teach us much about the effects of fan performance, filter loading, and cabinet placement on cabinet performance. 

Figure 9.8 Determining the performance envelope. A variation in line voltage can have a marked effect on the performance of a biological safety cabinet. The performance envelope allows the cabinet designer to predict the effects of changes of operating conditions on overall cabinet performance.

Liposomes can provide a type of envelope to protect solutions of biologicals against chemical degradation. The many application opportunities of liposomes are based on their ability to associate with other molecules. Hydrophilic molecules can be incorporated, amphiphilic and ionic molecules can be adsorbed at the surface, and lipophilic compounds can be dissolved within the membrane. The preparation of liposomes can be performed using a vari-...
