OMSONS

Class A glassware ships with a batch accuracy certificate and costs more; Class B does not and costs less. Class A matters for accredited labs, calibration work, or any procedure requiring documented traceability. For routine teaching or general prep work, Class B is a sound, more affordable choice.

Condensers, adapters, and flasks with ground glass joints only seal correctly when the taper sizes match across every piece in the train. Confirm the joint size on each item before ordering a distillation or reflux setup from separate pieces.

OMSONS' glass range is borosilicate 3.3, which resists thermal shock and most laboratory chemicals. This makes it suitable for direct heating and reflux work, unlike ordinary soda-lime glass, which can crack under rapid temperature change.

SmartLabs stocks a selected range of OMSONS' most reliable products rather than their entire catalogue. If you need an OMSONS item you don't see listed, contact us to check availability.

OMSONS is an Indian manufacturer of borosilicate laboratory glassware. This is confirmed as the country of origin on OMSONS product listings for procurement and tender purposes.

OMSONS' range is glassware, not electronics, so it is covered by our standard returns policy for manufacturing defects rather than a warranty. Class A items ship with their own batch accuracy certificate as proof of calibration.

Class A means the item ships with a batch calibration certificate proving its accuracy; Class B means it does not. This is purely a certification difference, not a build quality difference: both classes are made from the same borosilicate glass to the same manufacturing tolerances.
