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.
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.

For the past two decades, there has been much confusion about molecular gastronomy. This confusion has arisen because people ignore that the word gastronomy does not mean cuisine, it means knowledge about food. Similar to 'molecular biology', molecular gastronomy is a scientific discipline that looks for the mechanisms of phenomena occurring during dish preparation and consumption.
total soluble solids (TSS) of rotary evaporator or water bath methods, where they reached to 70.45 and 70.26%, respectively. Using higher temperature in water bath than rotary evaporator associated with increasing in the yield of dibs reached to 35.87 %, while it was 30.70% in dibs that concentrated with rotary evaporator.
The Magnetic Stirrers offered here represent the finest products of their kind in the industry, today. Whether ceramic, aluminum or acrylic top-design, our magnetic stirrers are built for durability and dependability. Likewise the shafted stirrers with propeller are available to fit the most demanding applications including very viscous liquid stirring.

The RV 10 control is the flagship of the new rotary evaporator series by IKA ®.It offers all the functions of the RV 10 digital. But the IKA ® RV 10 control goes one step further. Like the RV 10 digital, it can be precisely controlled via the RS 232 interface for remote PC operation with IKA ® 's labworldsoft ® and is thus ideal for automatic operation - but that's not all; the control .

Rotary evaporator system vacuum degree is higher than normal is the possible reason. If vacuum degree is too high, will cause solvent steam temperature is too low so couldn't be collected efficiently. Release vacuum is need, but other problems will happen if vacuum degree is too low.
