Metabolic cages provide uncontaminated, reliable samples for accurate metabolic  monitoring, In fact, a unique funnel-and-cone design completely and immediately separates feces and urine into tubes outside the cage. Its design prevent urine from washing over and entering the feces tube. Accommodating mice or rats, our Metabolic Cages offer 99% separation efficiency of urine and feces, assuring the maximum purity of samples. Each cage may be placed on a single cage stand or a stainless steel rack accommodating up to eight cages. Components below the cage floor are removable without disturbing animals allowing tests to be conducted over a prolonged period of time without interruptions. Featuring autoclavable polycarbonate and stainless steel components, these units are easy to assemble, maintain, disassemble and clean. Animals may be accessed without disassembly of cages.
Animal waste is directed through a collection funnel and onto a linear diffuser. The diffuser  allows the solid matter to travel down the top ridges of a 50% incline, passing over a urine port, and  into a fecal collection vessel. Liquid waste flows along grooves down the inclined diffuser, passing  through the urine port, and into a urine collection vessel. A urine deflector prevents excess urine  from splashing and contaminating the fecal specimens. Separate urine and feces samples are  collected in two standard 50 ml. centrifuge vessels.
