L (K3325) – Lot of 12\u003c\/h3\u003e\n\u003cp\u003eThe Bio-Serv® K3325 is a professional-grade environmental enrichment device engineered to support the natural burrowing, nesting, and sheltering behaviors of laboratory rodents within vivariums and biomedical research facilities. Fabricated from premium, high-purity **polycarbonate plastic**, these tunnels feature a transparent red tint that aligns perfectly with rodent visual physiology—blocking their perception of white light to create a secure, dark shelter while permitting unhindered, non-disruptive visual monitoring by facility technicians. Supplied as a tracking-coded lot of 12 tunnels, this durable model withstands repeated autoclaving cycles, complying fully with Good Laboratory Practice (GLP) and international animal welfare (AAALAC) standards.\u003c\/p\u003e\n\u003ch3\u003eTechnical Performance \u0026amp; Design\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eRodent-Blind Red Tint Spectrum: Outfitted with a specialized red hue that filters out bright ambient laboratory light waves.
