Breaking Down the Features of Whatman Grade 589, Black Ribbon, Quantitative Filter Paper, Whatman 10300010 Fltrppr 589/1 110MM Blk PK100, Pack of 100

Specifications

The Whatman Grade 589, Black Ribbon, Quantitative Filter Paper, Whatman 10300010 Fltrppr 589/1 110MM Blk PK100, Pack of 100 comes as a Pack of 100 individual filter papers, each with a diameter of 110mm. These are designed as quantitative filter papers, meaning they are intended for gravimetric analysis and other procedures where accurate quantitative results are paramount.

A key specification is its Large porosity, which contributes directly to its Fast flow rate. This combination allows for quick filtration without sacrificing the ability to retain fine particles. Specifically, the particle retention is rated between 20–30 µm, a critical parameter for separating precipitates of that size range.

The “Black Ribbon” designation likely refers to a specific manufacturing or treatment process that enhances its properties, such as resistance to cockling and outgassing, as mentioned in the product description. This detail is significant because it directly addresses potential sources of error in sensitive analytical procedures. The overall quality of the paper ensures it supports colorless chemistries and resists staining from common reagents.

Performance & Functionality

In its primary role as a quantitative filter paper, the Whatman Grade 589, Black Ribbon performs exceptionally well. Its main job is to efficiently separate solid particles from liquids, and it does this with remarkable consistency. The fast flow rate and large porosity allow for rapid processing of samples, saving valuable time in a busy laboratory setting.

A significant strength of this filter paper is its robustness. It actively resists cockling, which is the tendency for paper to wrinkle or curl when wet. This property is vital for ensuring that the filter bed remains flat and uniform, preventing the formation of channels.

The primary weakness, if one can call it that, is that these are specialized quantitative filters. They are not designed for qualitative tasks or high-volume, low-precision filtration where a cheaper option might suffice. For its intended purpose, however, the performance is squarely within expectations, and in many cases, exceeds them.

Design & Ergonomics

The design of the Whatman Grade 589, Black Ribbon, Quantitative Filter Paper is inherently simple, as is typical for filter papers. However, its “design” lies in its material science and manufacturing precision. The paper has a uniform texture and thickness, contributing to its predictable performance.

The black ribbon marking, though subtle, is a helpful identifier and likely signifies specific quality control measures during production. The 110mm diameter is a common size, making it compatible with standard Buchner funnels and laboratory filtration setups.

While “ergonomics” might seem out of place for filter paper, the ease of handling and folding is implicitly part of it. These papers fold cleanly, which is essential for forming conical filters used in gravity filtration setups. Their structure also makes them easy to place into filtration apparatus without tearing or collapsing prematurely.

Durability & Maintenance

As a quantitative filter paper, the Whatman Grade 589, Black Ribbon is designed for single use. Its “durability” is assessed by its ability to withstand the filtration process without compromising the results. In this regard, it proves highly durable.

The paper’s material composition is engineered to resist embrittlement, even when handling specific chemical compounds. It is also formulated to minimize outgassing, which is crucial when working with sensitive organic analyses.

Maintenance is, by design, non-existent. Once used, the filter paper and its captured solid are typically incinerated or disposed of according to laboratory protocols. The key is that it performs its function reliably during its single use, and that performance doesn’t degrade unexpectedly mid-filtration.

Accessories and Customization Options

For a quantitative filter paper, there are no traditional “accessories” or “customization options” in the way one might find with, say, a firearm or a piece of electronic equipment. The product itself is the consumable, designed for a specific purpose.
