Let’s Dive into Pall Acrodisc Sterile Syringe Filters, Pall Life Sciences 4908, Pack of 50
The Pall Acrodisc Sterile Syringe Filters, Pall Life Sciences 4908, Pack of 50 are a critical tool in any lab setting requiring sterile filtration. These filters, produced by Pall Life Sciences, promise to provide a reliable and effective method for sterilizing small to medium volumes of liquid. My own journey to these filters began with a growing frustration in the inconsistency of sterility in my field lab work; contamination was a constant, unwelcome guest.
I was seeking a solution that offered not just filtration, but also peace of mind, knowing that my results wouldn’t be compromised by rogue microorganisms. The Pall Acrodisc filters boasted a reputation for dependable sterilization, a key factor in my decision. Upon receiving the pack of 50, the first thing I noticed was the professional, individually blister-packed presentation. This immediately conveyed a sense of quality control and attention to detail, a reassuring sign for a product intended for such sensitive applications.
Compared to cheaper, non-sterile filtration options, the Pall Acrodisc offered a clear advantage in terms of guaranteed sterility and ease of use. I’d previously experimented with reusable filter setups, but the time invested in cleaning and autoclaving, plus the inherent risk of human error, made them far less appealing. The ease and reliability tipped the scales in favor of the Pall Acrodisc. My initial impression was one of cautious optimism; I was eager to put these filters through their paces and see if they could truly deliver on their promise of consistent sterility in challenging field conditions.
Real-World Testing: Putting Pall Acrodisc Sterile Syringe Filters, Pall Life Sciences 4908, Pack of 50 to the Test
First Use Experience
My first experience with the Pall Acrodisc Sterile Syringe Filters, Pall Life Sciences 4908, Pack of 50 was in a remote field lab during a water quality assessment project. The environment was far from ideal – high humidity, fluctuating temperatures, and the constant threat of airborne contaminants. Using the filters was surprisingly straightforward. I simply attached the filter to a syringe containing the water sample and slowly pushed the liquid through into a sterile collection vial.
The flow rate was noticeably consistent, and I appreciated the secure Luer-lock connections, which prevented any leaks or backflow. While I had initially anticipated some difficulty due to the viscous nature of the sample, the filter handled it with ease, minimizing the pressure required. Post-filtration, I incubated aliquots of the filtered sample to check for any signs of bacterial growth. The results were promising; no contamination was detected, a clear indication that the filter had successfully removed all microorganisms.
Extended Use & Reliability
After several weeks of intensive field testing, the Pall Acrodisc filters consistently delivered reliable sterility. We processed hundreds of samples under varying conditions, and the filters never faltered. Durability wasn’t a major concern, as these are single-use items, but the polypropylene housing proved to be robust enough to withstand the rigors of field handling. Maintenance was nonexistent, another plus for a fast-paced field operation; simply discard the used filter after each sample.
Compared to my previous attempts at using non-sterile, reusable filters, the Pall Acrodisc filters were a game-changer. The reduction in contamination rates significantly improved the accuracy and reliability of our data, justifying the cost. My previous method involved a painstaking sterilization process which was replaced by simply using a new sterile Pall Acrodisc filter for each sample. The Pall Acrodisc outperformed my previous methods by a considerable margin, providing consistent sterility and saving valuable time and effort.
Breaking Down the Features of Pall Acrodisc Sterile Syringe Filters, Pall Life Sciences 4908, Pack of 50
Specifications
The Pall Acrodisc Sterile Syringe Filters, Pall Life Sciences 4908, Pack of 50 boast several key specifications that contribute to their performance:
- Membrane Type: 0.2 µm Posidyne. This positively charged nylon membrane is designed to attract and retain negatively charged bacteria, ensuring effective sterilization.
- Flow Rate at 2.1 bar (30 psi): 77 mL/min. This indicates a reasonably fast flow rate, allowing for quick processing of samples.
- Pall No.: 4908. This is the specific product code for easy reordering.
- Unit: Pack of 50. Provides a convenient quantity for moderate to high-volume users.
- Effective Filtration Area: 2.8 cm2. This affects the flow rate and capacity of the filter.
- Maximum Operating Temperature: 60°C at 4.1 bar. Indicates the temperature limit for use without compromising the filter’s integrity.
- Maximum Operating Pressure: 5.4 bar at ambient temperature. Important for ensuring the filter doesn’t rupture during use.
These specifications are not just numbers; they translate directly into real-world benefits. The 0.2 µm Posidyne membrane, for example, is crucial for achieving true sterilization, as it effectively removes bacteria and other microorganisms. The flow rate dictates how quickly samples can be processed, a significant factor in time-sensitive applications.
Performance & Functionality
The Pall Acrodisc Sterile Syringe Filters, Pall Life Sciences 4908, Pack of 50 excel at their primary function: providing reliable sterile filtration. Accuracy is guaranteed by the 0.2 µm Posidyne membrane, which consistently removes bacteria. Reliability is evident in the consistent flow rate and robust construction, preventing leaks or ruptures.
Usability is high, thanks to the simple syringe-filter design, which requires minimal training. The only potential weakness is the relatively low flow rate for highly viscous liquids, which may require more pressure or pre-filtration. Overall, the Pall Acrodisc meets and exceeds expectations for sterile filtration, providing a consistent and reliable performance.
Design & Ergonomics
The Pall Acrodisc Sterile Syringe Filters, Pall Life Sciences 4908, Pack of 50 feature a simple, yet effective design. The polypropylene housing is lightweight and durable, comfortable to hold and manipulate. The Luer-lock connections ensure a secure fit with syringes, preventing leaks and backflow.
There is minimal learning curve; anyone familiar with standard laboratory techniques can use these filters with ease. The individually blister-packed design adds to the user-friendliness, ensuring sterility until the moment of use.
Durability & Maintenance
Given their single-use nature, long-term durability is not a primary concern for the Pall Acrodisc Sterile Syringe Filters, Pall Life Sciences 4908, Pack of 50. However, the polypropylene housing is robust enough to withstand normal handling and pressure during filtration.
Maintenance is non-existent; simply discard the used filter after each sample. This eliminates the need for cleaning, sterilization, or other maintenance procedures, saving valuable time and resources.
Accessories and Customization Options
The Pall Acrodisc Sterile Syringe Filters, Pall Life Sciences 4908, Pack of 50 themselves do not offer extensive customization options. However, they are compatible with a wide range of standard syringes and collection vials. Users can choose syringes of various sizes to accommodate different sample volumes.
Pre-filtration options, such as glass fiber filters, can be used upstream of the Pall Acrodisc to remove particulate matter and improve flow rates for heavily contaminated samples.
