Space-Saving Storage Bottles.These graduated laboratory bottles are rigid and feature a wide-mouth opening for easy filling and emptying of liquids and powders. The square shape allows the bottles to be tightly and neatly packaged side by side. In addition to the screw cap, a plastic plug stopper comes with each bottle, providing additional leak-resistance. Simply insert the plug stopper into the mouth of the bottle prior to closing the lid. This ensures a leak-resistant seal and makes these bottles ideal for transport and long-term storage. Confidential notes can be stored inside the bottle in the space between the plug stopper and the screw cap.
The cap and bottle neck have molded-in tagging points which are designed for securing the cap to the bottle using wire security ties. This makes the bottle tamper-evident. This bottle is approved for use with food products.
