Putri Deda Blog: Laporan Praktikum Rotary Evaporator

Oct 30, 2018 · Rotary evaporator adalah alat untuk efisiensi penguapan larutan dari sebuah campuran. A lat ini menggunakan prinsip vakum distilasi. Rotary Evaporator lebih disukai karena mampu menguapkan pelarut di bawah titik didih sehingga zat yang terkandung di dalam pelarut tidak rusak oleh suhu yang tinggi (Firdaus, 2011).

Antifeedant Effect of Some Medicinal Plant Extracts .

Background and Objective: At present, insecticides with raw materials of active compounds from plants have become a strategic alternative, because they are easily obtained and produced. In an attempt to find natural and cheaper methods for the control of rice weevil (Sitophilus oryzae L.), some useless waste of local medicinal plant extracts was evaluated.

The Self-Assembly Phenomenon of Poloxamers and Its Effect .

Commonly used solvent methods include vacuum drying using rotary evaporators [44], spray drying [45], or freeze-drying [46], among others. In rotary evaporators, solvents are removed under reduced pressure, limiting thermal decomposition of the components of the mixture as organic solvent evaporation occurs at low temperature.
