OVERVIEW:
GWSI Flat Bottom Borosilicate Crystallizing Dish with Spout 2000 ml is perfect for ultra-small volume evaporation and crystal growth. Premium borosilicate 3.3 glass provides high thermal shock resistance, hydrolytic resistance, and complete chemical inertness. The stable flat base supports even heating on hotplates while the spout allows precise pouring of tiny samples. This autoclavable lab glass performs consistently through multiple thermal cycles.
HISTORY:
Crystallizing dishes first appeared in 19th-century labs to support slow, controlled evaporation for growing pure crystals. The flat bottom design improved stability and uniform heat distribution. Borosilicate 3.3 glass later introduced high thermal shock resistance, making these dishes essential for precise micro-scale work in research and education.
APPLICATIONS:
– Pharmaceutical labs for precise formulation and dilution
– Biotech research facilities handling sample volumes
– 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 crystallizing dish via master hand-blowing or automated molding. Precision forming creates the flat base and integrated spout, 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 dish undergoes rigorous checks for dimensional accuracy and thermal 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 dish 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 racks to protect the flat base and spout
– Inspect for chips or cracks before each use
– Heat and cool gradually to avoid thermal shock
