30. Automatic Solvent Extraction
System
Velp Italy make L SER 148 3/ 6
Programmable Solvent Extraction System is used for rapid, safe & economic determination of soluble material in food,
feed, soil, polymer, textiles and environmental samples. Manufactured by an ISO 9001 certified company based on
technique Randall technique in accordance with AOAC, TAPPI, UNI, ASTM, APHA, AWWA, WEF, EPA etc.
The extraction cycle’s performance is further improved owing to uniquely designed thimble made of high quality cotton
cellulose fiber and extremely thin (1 mm) due to extreme thinness, the solvents flow through the thimble’s wall to be
faster. The above mentioned thickness features and optimum pressing of the cellulose fibers makes the surface the new
thimbles smooth and compact.
