Stax AKS Systems
Combining the high efficiency Seitz AKS media grades with the Stax capsule represents a milestone in the minimal handling of activated carbon.The StaxDepth Filter System Design Provides Simple and Intuitive Operation.
Placed into one of the three different sized chassis, Pall’s single-use Stax AKS capsules eliminate the use of stainless steel housings, which require costly cleaning and cleaning validation. Stax system chassis are designed for assembly and use by a single operator. They provide a logically conceived disposable platform. The operator can load, operate, and unload in an ergonomically designed vertical orientation. With simple, straightforward, and familiar features, the Stax platform eliminates the risk of error or mishap and enables greater process success.
Complete Flexibility in Process Design
The Stax platform has been designed to accommodate nearly all processing options. Whether you want to process:- Bottom up
- Top down
- Bottom-in/bottom-out
- In series
| Features | Benefits |
| No housing | Easier to use and manipulate while eliminating operator safety issues |
| Completely disposable | Eliminates need for cleaning and cleaning validation |
| Small footprint | Enables use in close proximity to other equipment and reduces cost to install |
| Intuitive design | Reduces operator training and time to acceptance |
| Encapsulated design | Reduces operator exposure to potential biohazards |
| Low hold up volume | Greater product recovery and lower post use rinse volume required than traditional modules and housings |
Seitz AKS Filter Media
Macro- and mesopores can generally be regarded as the highways into the carbon particle, and are crucial for adsorption kinetics. Macropores are used for the transport, and absorption occurs in the meso- and micropores. Small molecules, such as methylene blue, which has a molecular weight of 319.86 daltons, are mainly captured in micropores. For larger impurity molecules, other pore structures in the carbon must be available to ensure optimal adsorption. Carbon, which can capture larger molecules, tends to adsorb smaller impurities as well, whereas dedicated carbons for small molecules do not remove larger contaminants.The table below provides an overview of how different AKS grades may suit an application based on their general characteristics. However, due to the various factors that may affect the adsorption process, Pall recommends scaled-down testing of several Seitz AKS filter media using Pall UpScaleSM program test kits as the most reliable way. For more information on Pall’s depth filter system, please reference Pall data sheet USD 2459 or validation guide USTR 2491.

Highest Efficiency in Adsorption and Design
Powdered activated carbon (PAC) is widely used in the pharmaceutical industry for decolorization and removal of other trace impurities. The use of bulk PAC has significant drawbacks relating to the handling of bulk carbon powder, cleaning of process equipment, and time (costs) associated with carbon removal from the process. Seitz AKS immobilized carbon media alleviates these concerns by incorporating activated carbon within a matrix of cellulosic fibers. This immobilized carbon media is then coupled with a downstream filter paper to prevent carbon particle shedding downstream of the filter. Additionally, the adsorption efficiency of Seitz AKS immobilized carbon filter media is greater than an equivalent amount of bulk PAC, further reducing overall process time and increasing product yield.Comparison of PAC and Pall’s Seitz AKS Immobilized Activated Carbon Media
