Filter Papers Cellulose filter paper 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 applications and is frequently used for clarifying liquids. Traditionally the grade is used in qualitative analytical separations for precipitates such as lead sulfate, calcium oxalate (hot), and calcium carbonate. It is used for soil analysis and seed testing procedures. In the food industry, Grade 1 is used for numerous routine techniques to separate solid foodstuffs from associated liquid or extracting liquid and is widely used in education for teaching simple qualitative analytical separations.

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. PH40098

FLOATING RING MAGNETS Demonstrate magnetic repulsion in a colorful and memorable way. Includes: Five 12.6 in. (32cm) external diameter ceramic ring magnets; one 5.9 in. (15cm) wooden rod on base PH40095

LUNG APPARATUS PLASTIC W/TWO BALLOONS Show how the lungs are emptied and filled with air by relaxation and contraction of the diaphragm muscle! Two balloons attached to a Ytube simulate the lungs. The chest cavity is represented by a halfgallon plastic bell jar with an open top and stout rubber sheet which acts as a diaphragm. As the diaphragm is pulled downward, the atmospheric pressure is lowered inside the chamber causing the lungs to expand, taking in air. When the diaphragm is released, the lungs deflate.

ANEMOMETER Anemometer, rotating cups, pack of 50 units. The anemometer is useful for determining wind speed. It is made of corrosion resistant materials for prolonged outdoor use. One cup is red to facilitate the determination of the number of rotations. It is simple enough for students to understand and use, while accurate enough to be used by professional meteorologists in weather forecasting. The unit consists of a pole with rotating suction cups. These cups are mounted on horizontal arms that extend from the axis of rotation. When using it, make sure that each cup is pointed in the same direction with its face perpendicular to the floor. Includes: anemometer instructions. B19001

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 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 settle to form a dark layer. Students can predict the order in which different sediments settle along the bottom of a river or in a river delta. They can also classify the types of sediments and observe how organic material becomes trapped in sedimentary layers - the beginning of the fossilization process. Students can hold the tube horizontally and simulate different rates of water flow in a stream bed, showing how fast water must flow to move the different types of sediments downstream. They can also use their observations to determine how moving particles become rounded. B19140-S
