The M2 is a two-sided, two sample - sampling cassette, a true two for one cassette. Each cassette can be used to collect two samples, or one sample while using the other side as a control.
I've rated it 4 Stars but our Lab loves it. The lab like the sample size &
shape. Maybe they will write a review giving it 5 Stars.
The M2 is easy to use and allows us good choices as we develop our
sampling plans. The options include being able to draw 2 simultaneous
samples at the same location, and it is obviously easy to 'pair' samples.
Standard wall cavity adapters fit this cassette as well.
They have serial numbers, and there's enough room on the label to write.
Hurray!
It looses a star in our book because they have an expiration date.
Recently, we recieved a box from a vendor and it was out of date upon
arrival. They replaced the box and were good about over-nighting the
replacements, however the replacements are only good for 90 days. This
will limit me to ordering only 1 box at a time and eliminate any volume
discounts.
We'll keep buying the M2's because of the Lab loving them, but the ex
date is something that should be addressed. ~C
