The Pyrex Corning 8733-07 is a high-quality, 160mm graduated mercury manometer tube designed for precise pressure measurement applications. This manometer tube is made of durable Pyrex borosilicate glass, which is known for its excellent thermal shock resistance, making it ideal for use in both laboratory and industrial settings.
The tube features a 14/35 graduated scale, which allows for accurate measurement of pressure in millimeters of mercury (mmHg). The scale is etched onto the glass using a precise process, ensuring that the markings are clear and easy to read, even under magnification. The tube is also marked with a zero line, which helps to ensure that the manometer is properly calibrated.
The Pyrex Corning 8733-07 manometer tube is designed to be used with mercury, which is a common fluid used in manometers due to its density and low vapor pressure. The tube is sealed at both ends to prevent the escape of mercury, and it features a small vent hole at the top to allow for the introduction of mercury. The tube is also equipped with a U-bend, which helps to prevent the mercury from siphoning out of the tube when the pressure is lower than atmospheric.
The Pyrex Corning 8733-07 manometer tube is made to a high standard of craftsmanship, with smooth, even walls and a uniform diameter. The tube is also suitable for use in a wide range of temperatures, from -20 C to 300 C, making it a versatile tool for a variety of pressure measurement applications.
In summary, the Pyrex Corning 8733-07 is a high-quality, 160mm graduated mercury manometer tube that is suitable for precise pressure measurement applications. Made of durable Pyrex borosilicate glass, it features a 14/35 graduated scale, a sealed design, and a U-bend, making it a reliable and accurate tool for use in laboratory and industrial settings.
