Cellulose are manufactured from virgin cellulose fiber and used for general filtration. At Present we offer 1 to 6 grade filter paper with particle retention upto 2.5 µm to suit different laboratory applications. These cellulose filters are used in qualitative analytical techniques to determine and identify materials.

Filter papers are made on high tech machines and undergo a strict quality control both during production as well as packing.

Grade 1: 9 µm, Grade 1 filter paper is the most widely used filter paper for routine applications with medium retention and flow rate.

This grade covers a wide range of laboratory Grade 2: 9 µm, Grade 3: 5 µm, applications and is frequently used for Grade 2 filter paper is slightly more retentive Grade 3 filter paper is almost double the clarifying liquids. Traditionally the grade is and having more absorbing power than Grade thickness of Grade 1 with still finer particle used in qualitative analytical separations for precipitates such as lead sulfate, calcium 1 with a corresponding increase in filtration retention and excellent loading capacity; oxalate (hot), and calcium carbonate. time. In addition to general filtrations, the more precipitate can be held without extra absorbency is utilized, for example, to clogging. The extra thickness gives increased It is used for soil analysis and seed testing hold soil nutrient in plant growth trials. Also wet strength and makes this grade highly procedures. In the food industry, Grade 1 is used for monitoring specific contaminants in suitable for use in Buchner funnels.

MAGNETIC PENDULUM The Random Oscillating Magnetic Pendulum (ROMP) is a popular desktop toy. It consists of a pendulum, with a small magnet attached to the end, which can swing freely over a metal base. On the base there are nine numbers of strong, disc-shaped magnets, which act on the pendulum with either an attractive or repulsive force. When the pendulum is displaced and released, it tends to swing in an erratic, unpredictable pattern. Due to friction, the pendulum eventually comes to rest over one of the magnets. FLOATING RING MAGNETS PH40098 Demonstrate magnetic repulsion in a colorful and memorable way. Includes: Five 12.6 in. (32cm) external diameter ceramic ring magnets; one 5.9 in.

SEDIMENTATOR TUBE The Sedimentator is a tube with different types of sediments for students to use for observing movement, deposition, and layering of sediments and organic materials. These observations apply to In Development sedimentary rock formation and fossil formation. With just a gentle shake and a flip of the tube into an upright position, students can observe how sedimentation occurs in rivers, streams, swamps, marshes, lakes, and oceans. Letting the Sedimentator stand for several minutes will allow students to watch the suspended organic material slowly ORBITER settle to form a dark layer. Students can predict the order in which How many days does it take the Earth to revolve around the Sun?
