Air-O-Cell Cassette, 50/PK

Got within a day and don’t expire for year. Given that each home needs 3+ air samples, typically 50 get used faster than you think. Plus most labs will still take expired sample cassettes within a reasonable date from the expiration.

Zefon is as good a product as any others. A bit pricy compared to Allergenco.

Only cassette I would ever trust. So easy to collect perfect samples.

Great prices great service great product

these were ordered as a refill of our normal supplies when a local supplier was low on stock. Upon receiving and using the samples the Lab reported they could not perform the analysis as the coating on the slide in the sample was "melted" and the media was unreadable. Attempted to use a different lab to see if that was the issue and they came back with the same result - most of the samples were unreadable due to the melted coating.

Been using them for years.

Expiration date was May 2020 and I ordered in Jan 2020. They should be good for 2 years. Older stock.
