Histological grade solvents are specially prepared for tissue processing and other histological and cytological research procedures. Certificates of Analysis are available online or by scanning the QR code on the label.

Our research grade solvents for life science applications include DNase-, RNase-, and protease-free molecular biology grade products. Our ethanol solvents can be used with Invitrogen and Thermo Scientific purification kits.

Thermo Scientific molecular biology grade ethanol is an ultrapure grade ethanol used for the purification and precipitation of biomolecules such as nucleic acids and proteins. It can be used in histology to prepare staining and destaining reagents and for dehydrating tissues prior to embedding.

Key features:

  • Available in several concentrations
  • Tested for DNase, RNase, and protease to ensure absence of these enzymes
  • Meets ACS specifications for sbsolute ethyl alcohol
  • 0.2 micron-filtered
  • Water less than 0.2%


  • Purification and precipitation of nucleic acids (DNA and RNA) and proteins
  • Preparation of staining and destaining solutions
  • Dehydration of cells and tissues prior to paraffin wax embedding
  • Extraction medium
  • Chromatographic reagent

High purity isopropanol (IPA) is a staple solvent used in many life science laboratories. Our ultrapure molecular biology grade Thermo Scientific isopropanol can be used in research applications such as purification and precipitation of nucleic acids and proteins, and preservation of biological specimens.

Key features:

  • Ultrapure isopropanol (assay >99.9%) for molecular biology work
  • Tested for DNase, RNase, and protease to ensure absence of these hydrolyzing enzymes
  • Water <0.05%
  • Low UV optical absorbance
  • Variety of product pack sizes to meet various laboratory needs


  • Extraction and purification of nucleic acids, proteins, fats, and lipids
  • Preservation of biological specimens (nontoxic alternative to formaldehyde)
  • Disinfectant
  • Chromatography
