OVERVIEW:
GWSI Beaker Low Form 1000 ml is the standard stable vessel for mixing, heating, and reactions in daily lab routines. Crafted from premium borosilicate 3.3 glass, it delivers high thermal shock resistance and complete chemical inertness. The low-profile design with spout provides excellent balance and smooth pouring. Clear graduations support quick volume readings during routine experiments.
HISTORY:
Chemists in the 1800s needed vessels that resisted tipping during stirring of medium volumes. The low-form beaker, developed by John Joseph Griffin, solved the instability of taller designs while improving mixing and evaporation control. Borosilicate 3.3 glass later made this practical 1000 ml size safe for repeated heating and cooling cycles
APPLICATIONS:
– Pharmaceutical labs for solution preparation and mixing
– Biotech research facilities handling reagents and cultures
– Industrial chemical and petrochemical testing
– School and educational institute teaching experiments
– Colleges and university chemistry labs
– Research labs and analytical institutes
MANUFACTURING:
GWSI melts high-purity borosilicate 3.3 glass and shapes the low form beaker with spout via automated molding. Precision forming creates uniform walls and a controlled 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.
PRINTING PROCESS:
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 beaker 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 on stable shelves to support the wide base
– Inspect spout and walls regularly for chips or cracks
– Heat and cool gradually to avoid thermal shock
