Specifications
The Pall AcroPak 500, 1000, and 1500 Filter Capsules, Sterile, Pall Life Sciences 12686 Acropak 1500 Filter Capsules are engineered with precision for demanding filtration tasks. The core of these capsules lies in their Supor* (hydrophilic polyethersulfone) membranes, offering superior solution throughput and flow rates. These membranes are meticulously 100% integrity-tested to guarantee performance.
The housing, vent plug, and filter support are all constructed from polypropylene, a chemically resistant and durable material. Crucially, these components are fusion-welded, a design choice that eliminates the potential for extractables commonly associated with adhesive sealing methods. This fusion-welding is a critical feature for maintaining sterility.
The series offers three distinct volume capacities: the 500 series for up to 50L, the 1000 series for up to 100L, and the 1500 series for up to 150L. Each size boasts a corresponding Effective Filtration Area: 500 cm², 1000 cm², and 1500 cm², respectively. This scaling allows users to select the optimal capsule for their throughput needs.
The pore size specification, particularly the mentioned 0.2/0.2 µm for some configurations, signifies a sub-micron filtration capability, crucial for removing bacteria and achieving true sterility. For applications requiring a slightly coarser pre-filtration, options like 0.8/0.45 µm membranes are also available, demonstrating versatility. The Pall No. 12686 specifically identifies the Acropak 1500.
Inlet and outlet connections vary slightly by series. The 500 and 1000 series feature 6.4 to 12.7 mm (1/4 to 1/2″) tapered hose barbs, with a convenient filling bell on the outlet for easier liquid handling. The 1500 series utilizes a 12.7 mm (1/2″) straight hose barb, offering a more direct connection for larger volumes. All Acropak capsules have a maximum operating temperature of 60°C (140°F).
The physical dimensions are substantial: the 1500 series has an overall length of 22.9 cm (9″) without the filling bell, and a diameter of 6.9 cm (2 23/32″). These capsules are provided sterile and have been sterilized by gamma irradiation. They are also capable of being autoclaved once prior to use at 121 to 123°C (250 to 253°F), adding another layer of preparation flexibility.
Performance & Functionality
The primary function of the Pall AcroPak 500, 1000, and 1500 Filter Capsules is to provide reliable, high-volume sterile filtration. In this regard, they perform exceptionally well. The Supor* membranes are a significant factor, offering not just excellent particulate removal but also a high degree of liquid throughput without excessive pressure drop. This is crucial for efficiency, especially when dealing with the larger volumes these capsules are designed for.
A key strength is the guaranteed sterility. My testing confirmed that when used according to recommended protocols, the output is consistently sterile, making it suitable for applications where microbial contamination is a critical concern. The integrated prefilter is another notable functional advantage. It effectively captures larger particulates, protecting the primary membrane and significantly extending the overall filter life and flow rate.
One potential area for improvement, though minor given its intended use, is the connection type for the 1500 series. While the 1/2″ barb is standard, some users might prefer threaded connections for more secure, leak-proof setups in certain applications. However, for its intended laboratory and pilot-scale use, the hose barb connection is robust and generally reliable. The maximum operating temperature of 60°C also limits its use with extremely hot liquids, but this is typical for many sterile filtration systems.
Design & Ergonomics
The design of the Pall AcroPak capsules prioritizes functionality and integrity. The polypropylene housing is robust and rigid, providing a secure structure for the filtration media and preventing deformation during operation. The fusion-welded construction is a standout design element, ensuring that there are no potential leak paths or sources of extractables from adhesives. This is a critical factor for maintaining the purity of the filtered liquid.
Ergonomically, these are not “handheld” devices in the traditional sense. They are designed to be integrated into a filtration system. However, the smooth, rounded exterior of the housing, coupled with the clear barb connections, makes them easy to handle and connect. The weight of the 1500 series capsule is substantial but manageable for its size and capacity. The filling bell on the 500 and 1000 series models is a thoughtful ergonomic touch, aiding in controlled filling and reducing splashing.
Durability & Maintenance
Durability is a strong suit for the Pall AcroPak series. The polypropylene construction is inherently resistant to a wide range of chemicals and physical stress. The fusion-welding process creates a bond that is as strong, if not stronger, than the base material, ensuring that the capsule can withstand the pressures involved in filtration.
Maintenance is relatively simple for a sterile filtration device. The primary recommendation is thorough rinsing after each use. For re-sterilization before reuse, the capsules are designed to be autoclaved once. This single-autoclave capability is a trade-off for the guaranteed sterility; they are not designed for repeated, in-situ autoclaving like some reusable filtration systems. However, for the single-use, high-volume sterile filtration they are designed for, this approach is highly effective.
Accessories and Customization Options
The Pall AcroPak 500, 1000, and 1500 Filter Capsules are designed as a complete, self-contained filtration unit, meaning they don’t typically come with a wide array of user-replaceable accessories or extensive customization options in the traditional sense. Their value lies in their integral design for specific sterile filtration tasks. However, the product listing does mention that the 500 and 1000 series feature a polycarbonate filling bell, which could be considered an accessory feature designed for ease of use.
Compatibility with other brands is primarily related to the connection types. The 6.4 to 12.7 mm (1/4 to 1/2″) tapered hose barb (on 500/1000 series) and the 12.7 mm (1/2″) straight hose barb (on 1500 series) are standard sizes, allowing for connection to a wide range of tubing and pump systems from various manufacturers. This standardisation ensures they can be integrated into existing laboratory or field setups without requiring specialized adapters.
