Decolorizing a Solution of Impure Acetanilide and Hot Filtration
1) Set up a hot filtration apparatus using a stemless funnel, a fluted filter paper (the TA will
demonstrate), and a 125 ml Erlenmeyer flask. Place a small amount of recrystallizing solvent
Isolating the Recrystallized Product with Vacuum

Ultimately, digital PCR does not rely on the number of amplification cycles to determine the initial
amount of template nucleic acid in each sample; rather, it relies on Poisson statistics to determine the
absolute template quantity (5). Poisson statistic
Aneuploidies are a major cause of perinatal disease and death. Perinatal is the period immediately
before and after birth. It starts at twenty to twenty-eight weeks of pregnancy and ends one to four
weeks after birth. Therefore, it is the most
