General description

The Steridilutor® NEO device with expansion chamber is a tubing and needle assembly for difficult to dissolve powders, for dilution of super-potent antibiotics and pool products in vials. Pure products (solid or liquid) are difficult to rinse and residuals from products might be a major inhibitory factor in sterility testing. In the case of powders, a good dissolution is required to avoid any possible aggregate. A dilution step is strongly recommended for liquid antibiotics to reduce the concentration of the antimicrobial agent. This will reduce the possibility of binding of the agent to the filter. The expansion chamber vents residual vacuum or pressure from the vials without after-drip or contamination risk. The small diameter double needle connects test products with the diluent. The diluted product is subsequently filtered with suitable Steritest® NEO devices.


The Steridilutor® NEO Device with expansion chamber is used for the dilution of powders and super-potent antibiotics and to pool products in vials. The expansion chamber enables the venting of diluent container.
