Percival Scientific Biological Incubator Model I-22NL
Compact reach-in biological incubator without lighting for temperature-critical small organism research.
The Percival Scientific I-22NL Biological Incubator is a compact, reach-in environmental chamber designed for C. elegans, nematodes, yeast and fungi, insects, bacteria, and BOD testing where controlled temperature stability is required without internal lighting. Paired with the advanced IntellusUltra™ Controller, the I-22NL delivers precise, repeatable environmental control in a space-efficient laboratory footprint.
