ILAR Guide

Since its passage in 1966, the Animal Welfare Act and enhancements created by the Improved Standards for Laboratory Animals Act of 1985, have had a profound impact on the lives of both animals and people. To assist institutions and researchers in caring for and using animals in ways judged to be scientifically, technically, and humanely appropriate, the ILAR Guide* was created. The Guide is a generally accepted industry standard, and a primary reference on animal care and use, and for planning and conducting animal experiments in accord with the highest scientific, humane and ethical principles.

Lab Products is devoted to the design and manufacture of the highest quality laboratory animal housing and care equipment. Accordingly, throughout our product lines from individual Micro-Isolator™ cages to highly sophisticated environmental control systems that help protect both animals and personnel, our intent is to create products with specifications designed to meet or exceed ILAR Guide* recommendations. The health of our personnel, animals and facilities, even our overall industry depend on our collective actions.

We strive to provide solutions today and offer a vision of an even healthier tomorrow… for all of us.
