OVERVIEW:
GWSI Glass Lab (Ambala, Haryana — the Science City) builds this 100 ml low-form beaker with a neat pouring spout from premium borosilicate 3.3 glass. It packs high thermal shock resistance, complete chemical inertness, and full autoclavable durability into a tiny footprint. Small volumes, zero compromise — ideal for precise micro-prep where accuracy matters.
HISTORY:
Miniature low-form beakers appeared in early analytical chemistry to handle expensive or scarce reagents in tight quantities. The spout allowed clean transfer into micro-tubes without spills. GWSI continues that legacy, hand-crafting borosilicate 3.3 vessels for modern pharmaceutical, biotech, and university labs that demand precision at small scale
APPLICATIONS:
– Pharmaceutical micro-dosing and stability trials
– Biotech enzyme reactions and small-culture prep
– Industrial R&D micro-batches and pilot checks
– School, college, and university basic science labs
– Educational institutes teaching volumetric technique
– Research labs backed by I.S.O. DIN / NABL calibrated glassware
MANUFACTURING PROCESS:
GWSI melts high-purity borosilicate 3.3, shapes each 100 ml body through precise master hand-blowing or automated molding, strengthens via ceramic glass fusing, then completes a slow annealing cycle that fully relieves thermal stress for long service life.
TESTING PROCESS:
First test done by manual inspection for wall uniformity and spout form, followed by polarization stress test under polariscope light to confirm zero internal stress. Final verification uses I.S.O. DIN standard manual or automatic testing machines with NABL gravimetric calibration for volumetric accuracy.
PRINTING PROCESS:
This permanently fuses the print into the glass matrix, so it survives acids, autoclaving, and repeated washing without fading.
PACKAGING PROCESS:
Finished beakers pass cosmetic sorting to filter out any surface imperfections or rim defects. Approved pieces are packed in heavy-duty double-wall boxes with shock-absorbing bubble wrap, ensuring safe export delivery to your bench.
MAINTENANCE & SAFETY:
– Wash gently with mild lab detergent or compatible solvent; avoid abrasive scrubbers near graduations.
– Fully autoclavable at standard steam temperatures.
– Store upright in a padded rack; never stack unprotected.
– Inspect before heating; discard pieces with chips or visible stress lines.
– Always use tongs or heat-resistant gloves with hot glass
