Different applications may or may not require guaranteed purity levels of the chemicals being used. As a general rule, the higher the purity of a chemical, the higher the cost will be. For this reason, Nasco offers a variety of purities, or grades, of each chemical, depending on the application. Common chemical grades are:
ACS Reagent Grade -- Manufactured and guaranteed to the highest specifications as set by ACS (American Chemical Society). These chemicals are necessary for analytical applications requiring the most stringent standards.
Reagent Grade -- These chemicals are guaranteed to meet or be below maximum impurity limits as stated. Reagent grade is suitable for use in general analytical testing.
Laboratory (Educational) Grade -- The most economical of chemical, these general, all-purpose chemicals are suitable for use in applications where no specific purity and/or other standards are specifically called for. They are suitable for almost all educational applications.
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.
SOME PRODUCTS ARE SUBJECT TO AN ADDITIONAL $12.00 UPS HAZARDOUS MATERIAL SURCHARGE AND WILL APPEAR UNDER THE "Additional Information" COLUMN.
