Percival Scientific Biological Incubator Model I-66LLVL
High-Capacity, Lighted Environmental Incubator for Biological & Multi-Organism Research
The I-66LLVL Biological Incubator is a large-capacity, dual-door, fully lighted environmental chamber designed for drosophila rearing, culturing and holding of test organisms, bioassays, seed germination, and product stability testing. With high-intensity LED lighting, generous growing height, and precise environmental control, the I-66LLVL supports diverse biological workflows in a single, scalable platform.
