This Dynalon Boston round dropping bottle has an LDPE body and a screw cap with pipette and bellows-shaped bulb dropper top. This dropping bottle is used to dispense liquids in a unit of a drop in a dropping motion. The low-density polyethylene (LDPE) body is lightweight, flexible, and elastic, has an opaque hue, and resists impact, stress cracks, and moisture absorption. Its Boston round shape is used for applications that require a rounded body, short neck, and narrow mouth to store liquid samples, solvents, and chemicals, and dry materials. This lab bottle has a screw cap with dropper assembly to secure contents and help prevent spills and evaporations. The pipette and bellows-shaped bulb dropper top dispense drops of liquid in a dropping motion. The bottle's dropper pipette is graduated for measuring when dispensing.
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.
