OVERVIEW:
GWSI Glass Lab manufactures chromatography columns with a socket cone joint and integrated sintered disc from premium borosilicate 3.3 glass. Built for reliable separation with built-in filtration, they deliver high thermal shock resistance, full chemical inertness, and hydrolytic resistance. Every column is I.S.O. DIN, NABL calibrated for consistent analytical performance.
HISTORY:
Chromatography columns combining socket cone joints with sintered discs developed in mid-20th-century separation science to provide secure connections and built-in particle filtration in a single vessel. GWSI modernizes this integrated format with borosilicate 3.3 durability, ceramic glass fusing for disc and joint interfaces, interchangeable ground fittings, and autoclavable lab glass reliability.
APPLICATIONS:
* Pharmaceutical purification and compound isolation
* Biotech and analytical separation laboratories
* School, college, university, and educational institutes
* Industrial quality control and research labs
* Integrated filtration chromatography workflows
MANUFACTURING PROCESS:
We melt high-purity borosilicate 3.3, form the column tube through master hand-blowing or automated molding, apply ceramic glass fusing at the socket cone and sintered disc, incorporate interchangeable ground joints, and complete controlled annealing to fully eliminate thermal stress.
TESTING PROCESS :
Every column receives manual polariscope stress testing for zero residual stress, followed by high-precision ISO, DIN standard verification — manual or automatic testing machine — and NABL gravimetric calibration where volumetric measurement applies.
PRINTING PROCESS:
Graduations and markings are applied by precision screening with ceramic glass enamels, baked in high-temperature kilns to permanently fuse the scale into the borosilicate 3.3 matrix so it never fades.
PACKAGING PROCESS:
We perform cosmetic sorting to filter out any blemishes, confirm socket cone and sintered disc integrity, and pack in heavy-duty double-wall boxes with shock-absorbing bubble wrap for safe export from Ambala, the Science City.
MAINTENANCE & SAFETY:
* Autoclavable lab glass: sterilize at 121 °C with all openings clear.
* Clean with non-abrasive detergents; protect the socket cone, sintered disc, and ground joints from impact or abrasion.
* Confirm hydrolytic resistance before prolonged use with acidic or basic mobile phases.
* Store vertically in a stable rack away from direct heat sources.
* Inspect for polarization stress before high-thermal-shock cycles.
