The positive lock design of this contact plate prevents contamination after inoculation. The locking plate secures the sample by preventing the lid from separating and compromising the contents. The locking plate is suitable for a wide variety of uses including air sampling, all environmental monitoring, and personnel testing. Designed to open and close easily with a positive lock, the new product will eliminate the time, cost, and hassle of resampling. The plate is available with gamma irradiated standard media in triple-wrap packaging. Custom formulations are available upon request.
