Location and access
Describe the surface or monitoring location and any access constraints. Explain the problem in everyday terms before trying to select an item.
BioM / Environmental monitoring
Environmental monitoring product support
I support questions about ICR media and ICR swabs for cleanroom monitoring. Describe the location you need to sample, how accessible it is, and the supplies you currently use.
Before we talk
What should I bring to the conversation?
Start an environmental monitoring product discussion with the sampling location and the question you need to resolve. Flat surfaces, difficult-to-access areas, and different monitoring activities can call for different product conversations.
Three useful starting points
Current supplies
Share the product name or item number, format, packaging needs, and any handling question. Specific product documentation is the place to confirm storage and use requirements.
Scope of the question
Say whether you need help locating an item, understanding a product family, or planning team training. Monitoring plans and sampling frequencies remain part of your site’s program.
Products I support
Use the manufacturer’s pages for specifications, instructions, availability, and exact item selection.
ICR media
Ready-to-use contact and settle plates for monitoring cleanroom environments. The culture media portfolio includes irradiated, packaged options for critical sterile-production areas.

ICR swabs
A ready-to-use sampling system for qualitative detection of microbial contamination on dry surfaces. Useful for hard-to-access locations such as filling needles and tubing in cleanrooms and isolators.
Official product information ↗Ask me about this product →Questions you may have
Are ICR swabs and contact plates interchangeable?
They are different sampling formats. ICR swabs are described by the manufacturer for qualitative detection on dry surfaces, including difficult-to-access locations. Product selection needs to fit your monitoring application and procedure.
Where can I find current product instructions?
Follow the Sigma-Aldrich product links for documentation and current item details. If you cannot locate a particular document, send me the item number and what you need.
