Wide neck bottles made of clear DURAN® borosilicate glass 3.3, with GLS 80® thread, have three vertical baffles into the inner surface, the swirling motion is disrupted, giving a much more effective mixing motion.

• Bottles are fully autoclavable
• Easy to read graduated volume scale
• Very good temperature resistance
• Complete with PP pouring ring and GLS 80® screw cap

The baffles improve 'top to bottom' circulation and produce 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. Compatible with DURAN® GLS 80® magnetic stirrers, other magnetic stir bars, and with the full range of wide mouth GLS 80® connection cap systems for liquid addition or removal when mixing with stirring bars. The baffles are moulded into the glass side wall of the bottles and form a continuous, smooth inner surface making clean up easy.
