Filter Paper, Grade CFP1 Cellulose , cut 4.7cm dia, 11um, Medium flow. Qualitative grade. Antarisz brand. 100/pk
Laboratory filter paper is used for general filtration, sample clarification, and preparative laboratory workflows across a wide range of scientific disciplines. This category includes qualitative and quantitative cellulose filter paper suitable for routine laboratory use, sample preparation, and pre‑filtration prior to finer separation methods.
Filter paper is a foundational laboratory consumable, widely used in chemistry, life sciences, environmental testing, education, and analytical laboratories—including those that perform chromatography as well as non‑chromatographic work. Available in multiple grades and porosities, filter paper can be selected based on particle retention requirements, flow rate, and application needs.
Material & Performance Characteristics
The filter paper in this category is manufactured from high‑quality cellulose, offering:
Consistent fiber structure
Predictable filtration behavior
Reliable particle retention across common laboratory applications
Both qualitative filter paper (used where ash content is not critical) and quantitative filter paper (specified for low ash residue) are offered to support different laboratory requirements.
Applications & Use Cases
Laboratory filter paper is commonly used for:
General laboratory filtration
Sample clarification and cleanup
Buffer and reagent preparation
Gravity‑based and vacuum filtration
Educational and research laboratory workflows
Pre‑filtration prior to syringe or membrane filtration
In chromatography laboratories, filter paper is often used as a first‑step filtration tool, complementing membrane filters and syringe filters by removing larger particulates before finer filtration stages.
Product Line Scope
This filter paper category is a recent addition to the product offering, supplied through Cornerstone Scientific. The current selection focuses on essential grades used in routine laboratory applications, with additional formats and grades expected as the product line expands.
