2678 T Diffusion Shells. Schleicher & Schull's, 579. 



These shells are far superior to the parchment paper, be it in the shape of a hose or in connection with glass cylinders. 



With the very smallest volume they offer the largest possible surface, enabling work to be carried on with the smallest outside 

 vessel, combining greatest cleanliness with absolute reliability. 



Our dialysing shells are for this reason exceedingly valuable for experiments in the digestion of substances such as albumin 

 bodies, serum, in isolating poisonous substances from secretions and excretions. 



Packed in boxes with sliding covers containing twenty-five shells.
