This Nalgene heat-shrink band has a PVC body and a perforated tear strip, and it withstands gamma irradiation. This heat-shrink band provides a tamper-evident seal over a lab bottle's closure and neck to help protect the contents of the bottle. The PVC (polyvinylchloride) band provides flexibility, dimensional stability, flame resistance, and mechanical strength. This band withstands gamma irradiation for applications requiring sterilization. It has a perforated tear strip for ease of removal. This heat-shrink band is suitable for use in securing media bottles (sold separately).
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.
