About Thomas Glass Pycnometer Bottle, 50ml
Description This Thomas Gay-Lussac style pycnometer bottle has a glass body and a ground glass stopper with a capillary tube and a flat point. The pycnometer bottle (also known as a specific gravity bottle) is used to measure the density of a substance. The glass body provides solidity, transparency, solution compatibility, and versatility for use in an array of common applications, and it is heat, gas, and vapor resistant. This Gay-Lussac style pycnometer bottle has a pear-shaped flask with a stopper to contain substances and an external cap to reduce evaporation. The bottle has a ground glass stopper with a capillary tube that seals the bottle but allows air bubbles to escape for accurate density measurements. The stopper has a flat point for taking off the overflow of the substance to be measured from the capillary tube. This bottle has a label indicating its volume when filled with water at the listed temperature. The 10 mL and 25 mL bottles are for measuring specific gravity according to American Society for Testing and Materials International (ASTM) Standard D 369 and Barrett test H-8. This bottle is suitable for measuring the density and specific gravity of substances. Lab bottles are used to store, hold, and mix liquids, powders, and other substances in a wide variety of scientific industries. Lab bottles have a more pronounced neck and shoulder than jars. Lab bottles are manufactured with a combination of characteristics in order to meet the demands of particular applications, such as for solution dispensing, mixing, and weighing, and use in centrifuge operations. They come in many shapes for specific applications, with a variety of mouth or nozzle shapes and sizes for specific use. Lab bottles are made from materials, such as glass (borosilicate or soda-lime) and an array of plastics, which are selected for chemical and thermal expansion resistance, transparency, and their adaptability in a variety of applications. Lab bottle interiors, caps, and lids are often lined with a protective material. Caps and lids help seal bottles to prevent solutions from spilling. The capacity refers to the fluid amount held by a lab bottle, and is commonly measured in milliliters (mL) and liters (l), and sometimes in ounces (oz). Lab bottles are suitable for use in chemistry and biology applications, as well as in pharmaceutical and scientific testing. Thomas Scientific manufactures scientific supplies and equipment such as pH meters, balances, glass and plastic ware, baths, and centrifuges for life science, research, industrial and educational applications. Founded in 1900, Thomas Scientific is headquartered in Swedesboro, NJ.
