Filter Paper 15cm Lab Qualitative Grade 1 - Medium Flow 300 Discs

In this review the Fluted Filter 15cm Grade 1 discs are assessed as a straightforward, budget-friendly laboratory filter paper for routine separations. The bottom line: this pack of 300 discs is best for students, educators and labs that need reliable qualitative filtration and paper chromatography practice without paying a premium. The reviewer found the paper to offer medium flow and consistent retention suitable for fat determination, solids extraction and general clarification tasks, making it a pragmatic choice where value and compatibility matter.

Key Features

• Grade 1 equivalent: Standard qualitative filter paper comparable to commonly used lab grade for general separations and teaching exercises.
• 15cm diameter discs: Convenient pre-cut 150mm discs save time and are ready for funnels used in routine lab work.
• Medium retention / medium flow: Retains medium crystalline particles (roughly 10 to 15 micron) while allowing practical flow rates for common assays.
• Chemical compatibility: Produced with good chemical resistance and low ash content, suitable for many qualitative lab procedures.
• Multipurpose lab use: Suitable for extracting solids, clarifying liquids, determining fat content and teaching paper chromatography.
• Bulk value pack: Three hundred discs in a single pack provide cost-effective supply for classes or repeated experiments.

Who It's For

This product is aimed at teaching labs, college chemistry classes and small analytic labs that regularly run qualitative filtrations, fat determinations or basic chromatography demonstrations. The pre-cut discs and medium flow characteristics make it a practical choice when convenience and predictable performance matter.

Those who need ultrafine retention, quantitative analytical filter papers for critical trace analysis, or specialty filters for extreme chemical resistance should look for higher-grade or specialized filter media. For general classroom and routine lab filtration, this product meets the needs well.

Pros & Cons

Pros

• Good value for money with 300 pre-cut 15cm discs in one pack.
• Reliable medium retention and medium flow for common qualitative tasks like fat tests and clarification.
• Manufactured with attention to low ash content and moisture resistance, helpful for repeatable results.

Cons

• Not intended for ultra-fine particulate capture or specialized quantitative trace work where lower pore size is required.

Specifications

Our Verdict

These 15cm Grade 1 discs represent solid value for educational and routine laboratory filtration tasks.
