1 gallon or larger)

the standard high-concentration solvent for organic extractions

a two-ball refill when originals are lost or worn

Air condenser in borosilicate glass measures 20cm with 19/26 ground joint for high-boiling-point reflux and organic chemistry procedures

Separation Of Molecules AP Lab #5 Chemical_Fine White Sand Pair of Alnico bar magnetsStudents collect data using different solvents to identify the optimal solvent for separation. They will then illustrate the intermolecular forces that are acting on the molecules in the separation. Students evaluate the chromatograph with different solvents and establish a connection between molecular structure and intermolecular attraction to the solvent. The activity contains enough materials for 15 groups of students as well as a Teacher?s Guide
