• Dropping bottle used to dispense liquids in a unit of a drop in a dropping motion.
• LDPE body for flexibility, elasticity, and impact, stress-cracking, and moisture resistance, and is lightweight.
• Round shape used for a wide variety of common applications that require fluid containment.
• Screw closure with spout for dispensing one drop of liquid at a time.
• Captive spout cap remains in place while bottle is squeezed to secure contents.

The Nalgene round dropping bottle has an LDPE body, a screw closure with a spout, and a captive spout cap that stays in place. 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 round shape is used for a wide variety of common applications that require fluid containment. The bottle has a screw closure with a spout for dispensing one drop of liquid at a time, and it also has a captive spout cap that remains in place while the bottle is squeezed to secure contents. The bottle is suitable for most biotech, diagnostic, and ceutical applications. 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 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 a 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 ceutical and scientific testing. Nalge Nunc International manufactures plastic laboratory containers, outdoor sports bottles, and packaging materials under the Nalgene brand name. The company, founded in 1995, is headquartered in Rochester, NY.
