Walter Stern Glass Beads Soda Lime. These Glass Beads by Walter Stern easily pierce lab equipment or membranes used in qualitative procedures for bacterial and mycoplasma cultures. When in suspension these Walter Stern Lab Consumables gently agitate suspensions to release the trapped air bubbles. To separate the individual components simply agitate the suspension for a few seconds. These Walter Stern Lab Equipment are sized and tapered so that they offer gentle mixing without over-diluting the sample. Also to prevent etching of organic matter the Walter Stern Soda Lime Glass Beads 100E easily penetrate cell membranes without etching. When large enough these beads may be used in procedures for isolating and precipitating salts from glass wool. To initiate etching simply stop the etching and start over. The glass beads then fall to the bottom of the suspension. To release the oil place the bead on a suitable absorbent pad and let it set. Once etching is complete the glass beads may be reused without loss of identity.
