What is the price of HPLC acetonitrile?: 2/24/16 edition

Something that bothers me about spending on lab supplies is that it is very difficult to track the price of certain supplies. The amount of transparency is quite low; with that in mind, I plan to track the price of a 4X4L case of HPLC-grade acetonitrile weekly indefinitely as a public service.

I initially plan to look three places: the Sigma-Aldrich website, EMD-Millipore's site and also P212121, a site of Sean Seaver, a chemblogosphere stalwart. I have also added an unnamed lab supply house:

Sigma-Aldrich (4X4L, HPLC grade, ≥99.9%, 34851-4X4L): $1,150
Unnamed Very Large Supplier (4X4L, HPLC grade, 99.8% min (GC assay)): $190-230
EMD-Millipore (1X4L, HPLC grade, 99.8% min (GC assay), AX0145-1): $288.00*
P212121 (4X4L, HPLC grade, Purity >99.9%, PA-30000HPLCCS4L): $135.00**

*I know that EMD-Millpore offers 4X4L cases, but I can't find them on their public websites.

**There's a minimum of 5 cases. 


  1. If you're interested in taking a look at what kind of pricing a large research university might be getting, here's one data point that seems to be publicly accessible:

  2. Sigma's price does not reflect substantial discounts offered through a NAOSMM membership.

    1. This may be true, but it only serves to reduce the transparency about price that CJ is trying to study.

    2. Why is the unnamed supplier, well, unnamed? It kinda goes against the transparency.
