Breaking Down the Features of Whatman Grade No. 113V Folded Filter Paper, Whatman 1213-185, Pack of 100

The core of this product’s utility lies in its meticulously designed specifications. Each aspect has been engineered to address specific filtration challenges, making it a standout in its class.

Specifications

The Whatman Grade No. 113V Folded Filter Paper, Whatman 1213-185, Pack of 100 comes in a Pack of 100, offering a good bulk quantity for laboratory use. Each filter disk has a generous Diameter, cm of 18.5, providing a substantial surface area for filtration. It’s identified by the Whatman No. 1213-185, ensuring precise reordering.

The defining characteristic is its Porosity: Coarse, which allows for a rapid filtration process. This is complemented by a Flow Rate: Fast, making it the fastest flow rate of any qualitative grade in their lineup. Crucially, it boasts a Particle Retention of 30 µm, making it ideal for separating larger particles and coarse precipitates.

These specifications translate directly into practical benefits. The coarse porosity and fast flow rate mean less waiting time, a critical factor in high-throughput labs or when dealing with time-sensitive samples. The 30 µm retention is perfect for coarser precipitates and gelatinous materials that would quickly clog finer filters, preventing the need for multiple filtration steps or the frustration of slow throughput. The creped surface also aids in faster filtration by increasing the surface area and promoting better flow.

Performance & Functionality

In its primary role of filtration, this paper excels at handling coarse particles and those gelatinous precipitates that plague many lab processes. Its performance is best characterized by its speed and capacity; samples that would halt other qualitative filters move through this one with relative ease. The high wet strength is a significant advantage, ensuring the filter remains intact even when thoroughly saturated, which is vital for preventing sample contamination or loss.

Its main strength lies in its ability to handle large volumes of difficult-to-filter materials without clogging prematurely. This dramatically speeds up experimental workflows. A potential weakness, though inherent to its design, is its coarse nature; it is not for nitrogen determinations or applications requiring the retention of very fine particles below 30 µm.

Design & Ergonomics

The folded design is a simple yet effective ergonomic choice. It allows the filter paper to be easily opened and placed into a funnel, creating a conical shape that maximizes surface area and promotes efficient draining. The paper itself has a pleasant texture, neither too rough nor too smooth, which indicates a quality manufacturing process.

The material feels robust and substantial, giving confidence during handling. There’s no discernible learning curve; it’s a drop-in replacement for any standard qualitative filter paper of this size. The overall feel is one of quality and reliability, indicative of Whatman‘s reputation.

Durability & Maintenance

As a consumable item, the primary measure of durability here is its resistance to tearing and clogging. In this regard, the paper performs exceptionally well. I’ve subjected it to repeated wettings and the strain of gravity filtration without any issues. Its intended use is for qualitative filtration, so its lifespan is measured by how much material it can hold before requiring replacement, and it consistently exceeds expectations in this regard.

Maintenance is minimal. Once the filtration is complete, the used filter is typically discarded. The folded design and robust material make it easy to fold up for disposal without mess. There are no specific maintenance tips needed beyond standard laboratory waste disposal protocols.

Accessories and Customization Options

For this product, the “accessories” are essentially the filters themselves within the pack. The Pack of 100 ensures a ready supply for numerous experiments. There are no inherent customization options for the paper itself, as it is manufactured to a specific grade and size. However, its standard 18.5 cm diameter makes it compatible with most common laboratory filtration setups and funnels designed for this size.
