OVERVIEW:

GWSI Extractor for Soxhlet Apparatus performs continuous solvent extraction of solids in the lab. Premium borosilicate 3.3 glass with interchangeable ground joints delivers high thermal shock resistance, hydrolytic resistance, and full chemical inertness. The siphon mechanism enables efficient, repeated solvent cycling without manual intervention. This autoclavable lab glass stands up to demanding extraction cycles.

HISTORY :

Franz von Soxhlet invented the Soxhlet extractor in 1879 to extract fats from milk and other solids using continuous solvent reflux. Earlier manual methods were slow and inconsistent. The glass apparatus design allowed precise, automated extraction that became a standard in analytical chemistry.

APPLICATIONS:

– Pharmaceutical labs for active ingredient extraction
– Biotech research facilities handling natural compounds
– Industrial chemical and petrochemical analysis
– School and educational institute teaching experiments
– Colleges and university chemistry labs
– Research lab and educational institute projects

MANUFACTURING PROCESS:

GWSI melts high-purity borosilicate 3.3 glass and shapes the extractor via master hand-blowing or automated molding. Precision forming creates the siphon tube and interchangeable ground joints, followed by annealing to relieve thermal stress.

TESTING PROCESS :

Quality begins with manual inspection followed by polarization stress testing to ensure zero residual stress. High-precision verification follows I.S.O. and DIN standards using manual or automatic testing machines. Each extractor undergoes rigorous checks for joint fit and siphon performance.

PRINTING PROCESS :

GWSI applies permanent markings through precision screening with Glass Enamels (Ceramic Inks). These are baked in high-temperature kilns to permanently fuse the scale into the glass matrix, so it never fades.

PACKAGING PROCESS :

Final cosmetic sorting removes any blemishes. Each extractor goes into heavy-duty double-wall boxes with shock-absorbing bubble wrap for safe export.

 MAINTENANCE & SAFETY :

– Rinse immediately after use with mild detergent or suitable lab cleaner
– Autoclave safely at standard conditions
– Store upright in padded cases to protect ground joints and siphon
– Inspect joints and surfaces for chips or cracks before each use
– Heat and cool gradually to avoid thermal shock
