Condensers Allihn for Soxhlet Apparatus

• Manufactured from Boro 3.3 Glass.
• Printed in Anti Acid Blue Colour.
• Plastic Screw Thread Connector available with this Condenser.

OVERVIEW:

GWSI Allihn Condenser for Soxhlet Apparatus provides efficient vapor condensation during continuous extraction. Premium borosilicate 3.3 glass with interchangeable ground joints delivers high thermal shock resistance, hydrolytic resistance, and full chemical inertness. The series of internal bulbs greatly increases cooling surface area for rapid and complete condensation. This autoclavable lab glass pairs perfectly with Soxhlet extractors in demanding lab work.

HISTORY :

Friedrich Allihn developed the Allihn condenser in the late 19th century to improve cooling efficiency in reflux and distillation setups. Earlier straight-tube designs offered limited surface area and slow condensation. The bulb design solved these issues and became a standard component in Soxhlet extraction apparatus.

APPLICATIONS:

– Pharmaceutical labs for solvent reflux and extraction
– Biotech research facilities handling natural product isolation
– 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 condenser via master hand-blowing or automated molding. Precision forming creates the internal bulbs 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 condenser undergoes rigorous checks for joint fit and cooling 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 condenser 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
– Inspect joints and surfaces for chips or cracks before each use
– Heat and cool gradually to avoid thermal shock
