Whatman Grade 470 Special-Purpose Filter Paper, Whatman 10318493, Pack of 100 Review

Let’s Dive into Whatman Grade 470 Special-Purpose Filter Paper, Whatman 10318493, Pack of 100

The Whatman Grade 470 Special-Purpose Filter Paper, Whatman 10318493, Pack of 100 isn’t your everyday, run-of-the-mill filter paper. It’s a specialized tool crafted for specific applications in labs and potentially even niche outdoor scenarios. Made by Whatman, a respected name in filtration, this thick, absorbent paper promises consistent performance for filtering gelatinous precipitates, oils, and even serving as a blotting medium.

My journey to the Whatman Grade 470 started with a personal challenge: refining my own bio-diesel production. I was looking for a reliable way to filter out impurities and gelatinous byproducts. The promise of high absorbency and fast flow rate, as advertised for the Whatman Grade 470, steered me away from typical coffee filters and towards lab-grade solutions.

Upon unboxing, the first thing that struck me was the size of each sheet – a generous 46 x 57 cm. The paper felt robust, definitely thicker and more absorbent than standard filter paper, with a smooth surface. It has a reassuring quality, hinting at the durability and effectiveness I was hoping for.

Compared to standard lab filter paper I’ve used in the past (like Whatman Grade 1) and even cellulose-based coffee filters, the Grade 470 felt significantly different. It seemed designed for handling thicker, more viscous substances without tearing or clogging. It stood out in its size and perceived absorbency. My initial impression was one of cautious optimism – excited by the potential for superior filtration, but also slightly intimidated by its specialized nature.

Real-World Testing: Putting Whatman Grade 470 Special-Purpose Filter Paper, Whatman 10318493, Pack of 100 to the Test

First Use Experience

My initial test was in my small-scale bio-diesel setup. I used a sheet of the Whatman Grade 470 to filter a batch of freshly produced bio-diesel after the initial settling phase. The oil was still warm and contained a significant amount of sediment and residual glycerin.

The paper performed admirably; it handled the viscous liquid without any signs of tearing or saturation. The fast flow rate, as advertised, was noticeable – the filtration process was significantly quicker than when using standard filter paper. I did observe a slight “shedding” of the paper initially, with a few stray fibers visible in the filtrate, so a pre-rinse may be necessary for certain applications.

Extended Use & Reliability

After several weeks of consistent use, the Whatman Grade 470 has become an integral part of my bio-diesel refining process. It consistently delivers clean, sediment-free fuel. The durability of the paper is impressive; even with multiple uses and exposure to various solvents and oils, it maintains its integrity.

Cleaning is straightforward; larger debris can be brushed off, and the paper itself is disposable. Compared to my previous experiences with less robust filters, the Grade 470 has significantly reduced filtration time and improved the overall quality of my bio-diesel. The reduction of clogging is a huge benefit.

Breaking Down the Features of Whatman Grade 470 Special-Purpose Filter Paper, Whatman 10318493, Pack of 100

Specifications

The Whatman Grade 470 Special-Purpose Filter Paper, Whatman 10318493, Pack of 100 boasts several key specifications. Its dimensions are 46 x 57 cm, providing a large surface area for filtration. It’s categorized as having coarse porosity, allowing for fast flow rates.

The particle retention is specified as 20–30 µm, making it suitable for removing relatively large particles. The filter paper is made from thick, absorbent cotton linter. This makes it ideal for gelatinous precipitates and oils.

These specifications matter because they dictate the types of substances the filter paper can handle and the efficiency of the filtration process. The large size is useful for filtering larger volumes, while the coarse porosity ensures a fast flow rate, reducing processing time. The specified particle retention determines the size of particles that will be effectively removed, influencing the purity of the filtrate.

Performance & Functionality

The Whatman Grade 470 excels in its intended purpose: filtering viscous liquids and removing relatively large particles. Its performance is consistent and reliable, providing a clear filtrate with minimal effort. However, it is not suitable for applications requiring the removal of very fine particles, due to its 20-30 µm particle retention.

Its strengths lie in its high absorbency, fast flow rate, and large sheet size. It’s a perfect choice when dealing with substances that tend to clog finer filters. Areas for improvement might include surface treatment to minimize initial fiber shedding.

Design & Ergonomics

The design of the Whatman Grade 470 is simple and functional. The thick, smooth-surfaced paper is easy to handle and fold into various filtration setups. Its weight and texture feel substantial, inspiring confidence in its durability.

There’s no real “learning curve” associated with using this filter paper; it’s as straightforward as filter paper gets. Its large size offers flexibility in adapting it to different filtration apparatus.

Durability & Maintenance

Given its construction from thick cotton linter, the Whatman Grade 470 is surprisingly durable. It can withstand repeated handling and exposure to various liquids without significant degradation. Maintenance is minimal; simply dispose of the used filter paper after each filtration.

Proper storage (away from moisture and contaminants) will ensure its longevity. The product should last a considerable amount of time, with the pack of 100 sheets providing ample supply for extended use.

Accessories and Customization Options

The Whatman Grade 470 Special-Purpose Filter Paper, Whatman 10318493, Pack of 100 itself doesn’t come with any specific accessories. However, its versatility lends itself to use with a variety of filtration apparatus, funnels, and support structures. You can customize the size and shape of the filter paper by cutting it to fit your specific needs.

It is compatible with various filtration setups, including Büchner funnels, gravity filtration systems, and even homemade filter arrangements. The user could benefit from the Whatman range of filtration devices, but the paper works well with 3rd party funnels also.
