Hawach Qualitative Filter Paper BIO-1 Introduction

Hawach BIO-1 filter paper has a particle retention of 11 μm. BIO-1 filter paper is the most frequently used in daily filtration. It is a chemical analysis filter paper with medium retention capacity and flow rate. The diameters are 55mm, 70mm, 90mm, 110mm, 125mm, 150mm, 180mm, 185mm, 240mm, 270mm. This level covers most laboratory applications and is often used for liquid clarification. Also isolated by traditional qualitative analysis of precipitates, such as lead sulfate, calcium oxalate (hot), and calcium carbonate, which are cellulase activity, drilling fluid reactive clay, protective cloth resistance, penicillin, solid waste, chlorine weeding standard filter paper for the determination of the agent.

Filter Paper Type

Hawach Qualitative Filter Paper BIO-1 is a type of cellulose-based filter paper specifically designed for qualitative analysis. It is commonly used for tasks where the identification and presence of substances in a sample are the primary focus

Key Features of Qualitative Filter Paper

  1. Particle Retention: BIO-1 filter paper offers effective particle retention capabilities, allowing for the filtration of solid particles in various qualitative analysis procedures. The specific particle retention size of the filter paper is designed to meet the needs of qualitative analysis applications. Qualitative filter papers come in different grades with varying particle retention capacities. The choice of grade depends on the size of particles you want to retain.
  2. Flow Rate: The porosity of the filter paper determines the flow rate of the liquid through the paper. Qualitative filter papers are generally designed to provide a balance between particle retention and flow rate.
  3. Filtration Speed: BIO-1 filter paper provides a moderate filtration speed, striking a balance between efficient filtration and sufficient time for accurate analysis. The controlled filtration speed helps ensure reliable and reproducible results.
  4. Material: The filter paper is made from pure alpha cotton cellulose, sourced from sustainable forests. The use of high-quality cellulose ensures reliable performance and minimal interference with the analyzed substances. Typically made from high-quality cellulose fibers, these papers may have additives to improve wet strength, chemical resistance, or other specific properties.
  5. Applications: Used for a wide range of applications, including routine laboratory filtration, clarification of solutions, and qualitative analysis where fine precipitates are collected.
  6. Sizes and Formats: Available in various sizes, including sheets and discs, to fit different filtration apparatus. The BIO-1 filter paper is available in various sizes and shapes, including circles and sheets, to accommodate different laboratory setups and filtration needs. The availability of multiple sizes allows for flexibility in choosing the appropriate filter paper for specific applications. Common diameters for discs include 70 mm, 90 mm, and 125 mm.
  7. Grade Identification: Filter papers are often labeled with a specific grade that corresponds to their particle retention characteristics. The grading system varies among manufacturers.
  8. Compatibility: Suitable for use with a variety of chemicals and solvents commonly used in laboratory work.
  9. Certifications and Quality Assurance: Hawach Qualitative Filter Paper BIO-1 complies with international quality standards and is manufactured under strict quality control processes. The filter paper is designed to provide consistent performance, reproducibility, and accurate results.

Applications

Hawach Qualitative Filter Paper BIO-1 is suitable for a wide range of qualitative analysis applications in laboratories. It is commonly used for tasks such as gravimetric analysis, sample preparation, clarifying liquids, and general qualitative separations.

1. In agriculture, it is used for soil analysis and seed testing.
2. In the food industry, BIO-1 filter paper is often used to separate solid foods or extract liquids from related liquids and is also widely used for simple qualitative analysis and separation in teaching.
3. In the aspect of air pollutant monitoring, there are discs and coils available for use, collecting atmospheric dust from the atmosphere and then measuring the degree of pollution with a photometer.
4. In gas detection, the filter paper is soaked with a coloring agent and quantified by light reflection
