    N95 Respiratory Mask

    Category:

    Details:

    • Company Name: Degil
    • An N95 respirator is a respiratory protective device designed to achieve a very close facial fit and very efficient filtration of airborne particles.
    • The edges of the respirator are designed to form a seal around the nose and mouth.
    • A face mask is a product that covers the wearer’s nose and mouth.
    • The mask is designed to inhale clean dust free air.
    • Face masks are for use as source control by the general public and health care personnel (HCP) in accordance with CDC recommendations.
    • The face covering helps to avoid spreading of the virus by stopping the respiratory droplets which contain viral particles.

    Oersted’s Apparatus

    Oersted’s Apparatus

    SKU: 0914-1401 Category:

    Details:

    • Oersted developed a principle that describes the magnetic field around a current- carrying conductor.
    • Oersted principle states that a charge moving through a straight conductor produces a circular magnetic field around the conductor.
    • This instrument shows the action of electric current on a magnet.
    • Instrument is used to show the magnetic field created by the current during experiments.
    • A cobalt-steel needle (75 mm long) with agate bearing supported by a pivot is mounted on a plastic base and surrounded by a rectangular frame fitted with terminals.
    • Setting up a compass through a wire carrying an electric current, Oersted’s apparatus shows that moving electrons can create a magnetic field.
