General description

During mixing in standard GLS 80 laboratory bottles, the liquid moves in a swirling motion that
approximates a solid-body rotation. The entire fluid, and any suspended particles, moves like a carousel.
This is a very inefficient flow pattern, and very little mixing actually occurs. By adding three vertical baffles
into the inner surface of the GLS 80 bottles, the swirling motion is disrupted, and a much more effective
mixing occurs. The baffles improve the top-to-bottom circulation and produce a greater radial mixing. The
baffles also offer other advantages such as suppressing the formation of a central vortex, and reducing
dead-zones where mixing does not occur.

Features and Benefits

  • The baffled GLS 80 bottles are fully compatible with both the DURAN GLS 80 magnetic stirrers, and other magnetic stir bars.
  • Manufactured from DURAN borosilicate 3.3 glass, renowned for its excellent thermal performance and high resistance to chemical attack.
  • The baffled GLS 80 bottles are fully autoclavable.
  • Available in three convenient sizes: 250, 500 and 1000 ml.
  • The wide 65 mm inner diameter of the GLS 80 wide mouth provides easy access to the contents,or for cleaning.
  • The baffles are moulded into the glass side wall of the bottles and form a continuous, smooth inner surface making clean up easy.
  • Compatible with full range of wide mouth GLS 80 connection cap systems for liquid addition or removal when mixing with stir bars.
  • The bottles feature an easy-to-read graduated volume scale.
