The Whatman 1454-055 and 1450-055 Hardened Filter Papers are high-quality, lab-grade filtration tools designed for precise and reliable filtration in various scientific applications. These filter papers, available in the grade 50 and 54, have a diameter of 5.5 cm, making them suitable for a wide range of experimental setups.
The Whatman 1454-055 and 1450-055 Hardened Filter Papers are made from a special cellulose nitrate material, which has been treated to create a hardened, rigid filter medium. This hardened structure provides several advantages over traditional soft filter papers. Firstly, it allows for easier handling and stacking, reducing the risk of damage during storage and transportation. Secondly, the hardened structure ensures a consistent pore size, providing reliable filtration results.
The grade 50 and 54 refer to the pore size of the filter paper, with a smaller pore size indicating a finer filtration. The grade 50 filter papers have a pore size of 0.6 m, while the grade 54 filter papers have a pore size of 0.4 m. This makes the 1454-055 filter papers suitable for filtration of particles up to 0.6 m in size, while the 1450-055 filter papers are suitable for filtration of particles up to 0.4 m in size.
The Whatman 1454-055 and 1450-055 Hardened Filter Papers are designed to be used with standard filter funnels and vacuum pumps. The stiffness of the filter papers allows for easy assembly and disassembly of the filtration setup, while the consistent pore size ensures reliable and reproducible filtration results.
Overall, the Whatman 1454-055 and 1450-055 Hardened Filter Papers are essential tools for any laboratory that requires precise and reliable filtration of liquid samples. Their hardened structure, consistent pore size, and ease of use make them a popular choice among scientists and researchers.
