  4. Graduated pipette - Wikipedia

    en.wikipedia.org/wiki/Graduated_pipette

    A small pipette allows for more precise measurement of fluids; a larger pipette can be used to measure volumes when the accuracy of the measurement is less critical. Accordingly, pipettes vary in volume, with most measuring between 0 and 25.0 millilitres (0.00 and 0.88 imp fl oz; 0.00 and 0.85 US fl oz). [2]

    Volumetric pipettes or bulb pipette allow the user to measure a volume of solution extremely precisely (precision of four significant figures). These pipettes have a large bulb with a long narrow portion above with a single graduation mark as it is calibrated for a single volume (like a volumetric flask). Typical volumes are 20, 50, and 100 mL.

    (These are for Class A pipettes; Class B pipettes are given a tolerance of twice that for the corresponding Class A.) A specialized example of a volumetric pipette is the microfluid pipette (capable of dispensing as little as 10 μL) designed with a circulating liquid tip that generates a self-confining volume in front of its outlet channels. [3]

    en.wikipedia.org/wiki/Safety_lamp

    A safety lamp has to ensure that the triangle of fire is maintained inside the lamp, but cannot pass to the outside. Since any breathable atmosphere contains oxygen, and a safety lamp's raison d'être is to operate in an atmosphere also containing fuel (firedamp or coal dust), the element which must be blocked is heat. The key to manufacturing ...
