Placed into one of three different sized chassis, Pall’s single use Stax 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 and provide a logically conceived disposable platform in which the operator can load, operate and unload in an ergonomically designed vertical orientation. The ability to operate with two different media grades in one chassis (serial filtration) further improves the flexibility and economy of operating the Stax platform. With simple, straight forward and familiar features, the Stax platform eliminates the risk of error or mishap and enables greater process success. Integrating Pall’s Allegro™ platforms into a comprehensive single-use system will further maximize the overall benefits of implementing a single-use strategy and the Stax platform.

 

 

Features	Benefits
Low hold-up volume	Greater product recovery and lower post use rinse volume requirements than traditional modules and housings. Post use blow down in forward or reverse flow direction are possible.
Seamless linear scalability	Greater flexibility and assurance of process success from <1L to 20,000+ L Scalable through Pall’s entire line of scale-up devices (Supracap™ 50 and Supracap 100 capsules) as well as traditional Supradisc I and Supradisc II modules. Provides assurance of meeting process design and requirements.
Minimized risk	The Stax capsules are based upon the outstanding design of Pall’s Supradisc II modules, which provides benefits in process stability due to their high mechanical robustness.
No housings	Easier to use and manipulate while eliminating operator safety issues.
Completely disposable	Eliminates need for cleaning and cleaning validation.
Encapsulated design	Reduces operator exposure to potential biohazards.
Intuitive operation	Reduces operator training and increases time to acceptance.
Small footprint	Enables use in close proximity to other equipment and reduces cost to install.

 

Minimized Risk

 

Benefiting from Pall’s Supradisc II mechanically robust module design, the Stax capsules provide stable filtration results batch to batch. Through the use of interlocking and welded dual drainage plates, this robust module design is able to provide the structural integrity necessary for:

 

• Unobstructed process flow
• Consistent filtration results
• Minimized risk to filter media ruptures due toreverse pressure
• Minimized risk of damage due to shipping and handling

 

Seitz depth filter media available in Stax capsules:

 

P-series

 

Seitz P-series depth filter sheets were specifically developed for the strict requirements in biotechnological and pharmaceutical industries. Manufactured with stringent in-process control methods assures consistent filtration quality, a very high purity of filter medium, and alignment with the requirements of the pharmaceutical industry. For further information, please reference Pall data sheet USD 2205 or validation guide USTR 2366.
