Product Description

This Wheaton Boston round media bottle has a borosilicate glass body, a sealed, linerless polypropylene screw cap with a pour ring, and a marking area. This media bottle is used to hold samples and for storage, mixing, and sampling applications. The borosilicate glass body provides chemical, thermal expansion, shock, and heat resistance. Its round shape is used for a wide variety of common applications that require fluid containment. The white, linerless polypropylene cap secures contents and helps prevent spills and evaporation. This cap has a plug seal that presses against the rim of the bottle to provide a tight seal and a barrier against moisture and gas. A removable polypropylene pour ring neck insert helps reduce drips when dispensing contents

This lab bottle has a marking area to label for security and accountability, and it is graduated for measured dispensing and storing. The bottle, cap, and pour ring are autoclavable for applications that require sterilization. The borosilicate glass conforms to United States Pharmacopoeia (USP) Type I requirements for glass containers. This bottle is suitable for mixing and storing samples, reagents, culture media, biological fluids, and other liquids.

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.
