Ethanol 200 Proof (100%), Suitable for Molecular Biology is undenatured ethanol in liquid form, supplied as Molecular Biology Grade with an assay of ≥99.5%. It’s a high strength alcohol meant for bench work where you need a consistent starting material. Lab Alley sells it in 1L, 1 gallon and 4L sizes, plus cases of 4 x 1L, 4 x 1 gallon and 4 x 4L. The paperwork is easy to find. Under Product Manuals you’ll see the Safety Data Sheet, Technical Data Sheet, Allergen Statement, BPA Statement, Non-Irradiation Statement, PFAS/PFOS Free Statement and TSE/BSE Declaration. Certificates of Analysis for several lots are posted there too, so you can compare results with your own requirements.
Most people reach for molecular biology grade ethanol for DNA and RNA precipitation, wash steps in nucleic acid purification and making up buffers and stock solutions. The trouble starts when a bottle doesn’t match what your protocol expects, the paperwork is missing, or your supplier can’t deliver the size you need on time. Lab Alley is built to fix that. Documents are available instantly on this page, sizes run from 1L up to cases and bulk, and if your order needs hazmat handling, we manage it from start to finish. Pick the size that fits your workload, set up Autoship if you use it regularly, or request a quote for larger volumes. Our promise is simple: on budget, on time, every time. Request a quote and we’ll take it from there.
