1000pcs Professional Grade 2 Qualitative Filter Paper - High Purity and Finer Retention
Elevate your laboratory filtration standards with our Grade 2 Qualitative Filter Paper. Specifically designed for general laboratory filtrations, material identification, and routine analytical applications, this media offers a higher level of particle retention and absorbency compared to standard Grade 1 paper, with a corresponding, controlled increase in filtration time.
Particle Retention in Liquid: 8 um (at 98% efficiency)
Filtration Speed / Flow Rate: Medium (55-60 seconds for 10 ml water through 10 cm2 at 23 +/- 1 degrees C)
Thickness: 0.21 mm
Basis Weight: 103 g/m2
Wet Burst Strength: 290 mm H2O (measured via specialized wet burst instrumentation)
Ash Content: Less than 0.15% (achieved via clean air ignition at 900 degrees C)
Order Includes: 10 Packs of 100 pieces (1000pcs)
Crafted from nearly 100% pure alpha-cellulose, this filter paper guarantees excellent chemical stability and consistency across batches. The low ash content minimizes background interference, ensuring that your qualitative analyses remain precise and reproducible.
Thanks to its enhanced absorbency and precise 8-micron rating, this Grade 2 paper is highly utilized across multiple disciplines:
Agricultural Science: Ideal for soil testing, core nutrient retention, and specialized plant growth trials.
Environmental Monitoring: Efficiently captures solid contaminants and particulates suspended in air or soil extracts.
General Chemistry: Perfect for routine laboratory liquid clarifications and identifying unknown crystalline precipitates.
Whether you are conducting environmental safety checks, agricultural assessments, or standard laboratory separations, this Grade 2 filter paper delivers the dependable structural wet strength and fine particle capturing capabilities your work demands.
High-Precision 8um Particle Retention: Grade 2 qualitative filter paper is engineered to efficiently retain particles above 8 um with a 98% efficiency rating. It offers slightly finer retention and higher absorbency than Grade 1, making it ideal for routine analytical workflows and demanding laboratory clarifications.
Premium Alpha-Cellulose Composition: Manufactured under strictly controlled conditions, these filter papers consist of nearly 100% high-purity alpha-cellulose. With an ultra-low ash content of less than 0.15% (determined by ignition at 900 degrees C), they ensure excellent structural integrity and reliable, uncontaminated results.
Optimized Medium Flow Rate and Strength: Features a balanced flow rate of 55-60 seconds (for 10 ml distilled water through 10 cm2) and a robust wet burst strength of 290 mm H2O. This ensures the paper maintains its stability and resists tearing under standard wet filtration pressures.
Versatile Laboratory and Agricultural Applications: Perfectly suited for environmental monitoring, soil quality analysis, and plant growth trials where extra absorbency is required to hold nutrients. It is also widely used for contaminant monitoring in both air and liquid samples.
Industry-Standard Performance: Delivers professional-grade performance, thickness (0.21 mm), and basis weight (103 g/m2), seamlessly integrating into standard laboratory setups and demanding separation workflows.
