Choose these wide neck storage bottles from RS PRO for a reliable storage solution in your educational or industrial lab. They can safely store samples of powders, liquids and other materials. As they're made from a durable polypropylene (PP) material, the bottles are highly resistant to chemicals and corrosion for use in harsh environments. They're translucent, so you can easily identify your samples. As the PP material can withstand high temperatures, it's safe to sterilise the bottles in autoclaves at temperatures of up to +121°C. For ease of recycling, each bottle has a moulded SPI (Society of the Plastics Industry) recycling code so recyclers can easily identify the plastic type. These bottles are commonly used for a variety of purposes in laboratory settings.
