Practical Grade -- Sufficiently high quality for use in many syntheses and other applications.
Technical Grade -- Selected commercial grades, scrupulously clean, and of reasonable chemical purity. Where usable, most economical grade and suitable for educational purposes.
Organic Chemicals -- Fall into reagent, practical, and technical grades, with specifications generally determined by melting or boiling point.
Biological Stains and Solutions -- We have greatly expanded our offerings of biological stains and ready-to-use staining solutions. Every effort has been made to include affordable and practical small package sizes. All dry stains are of certifiable quality. They are for use in the most exacting work in biology, cytology, etc.
Indicators -- As with biological stains, we have also expanded the indicators in our chemical list. Small, practical, and affordable package sizes are included. All indicators and indicator solutions are of the highest quality for laboratory use.
Due to the fact that packaging of chemicals changes frequently, quantities may vary from listing, depending on availability.
