Description
Pear-shaped flask with standard ground joint, capacity marking and frosted label area is a borosilicate laboratory vessel designed for routine heating, mixing and reaction work. Made from Boro 3.3 glass with white inscription, it offers a nominal volume of 1000 ml and a female ground joint NS 29/32 for secure connection to condensers, adapters and other standard joint glassware. The pear-shaped body supports efficient swirling and drainage, while the capacity marking and frosted label area allow clear volume reference and sample identification at the bench. Supplied without stopper, the flask integrates easily into existing joint assemblies. This model from manufacturer Hecht suits organic synthesis, distillations and general preparative chemistry where thermal shock resistance and chemical durability of borosilicate 3.3 are required. The white lettering remains legible under typical laboratory lighting and cleaning cycles. Packaged as a multi-piece unit for stock replenishment in teaching and research laboratories, it provides a practical, standardised pear-shaped flask for everyday glassware setups.

Questions about Flasks, rotary evaporators with ground socket, Boro 3.3, printing white,
What is this article?
Flasks, rotary evaporators with ground socket, Boro 3.3, printing white, is the article on this page. Luminix Health distributes Hecht for laboratory use. It sits in Laboratory labels, inside Labels, signs & marking, in Lab safety equipment.
A laboratory label has to stick to a cold, a wet or a curved surface and stay legible. Cryo labels, autoclave labels and ordinary bench labels are different adhesives. The size and whether it takes pencil, print or a thermal transfer are the choices.
A label is how the next person knows what is in the bottle. A GHS label carries the pictogram, the signal word and the hazard statements the classification requires. A tape or a marker is only as useful as its survival in the freezer, the autoclave or the solvent it will meet. A safety sign is the instruction that stays on the door. The pictograms come from the CLP Regulation and are explained by ECHA CLP. Workplace signs sit with EU-OSHA.
