Borosillicate glass is not toxic; it is a safe type of glass. It is used in making many types of products such as cookware and lab equipment.
It's safe to drink water boiled in this glass IF no poisons have ever been put in the glassware. Borosilicate is the glass originally used to make Pyrex cookware--in Europe they still use it, but in the US a different glass is used that doesn't break as easily when dropped.
Thermostable glass is a borosilicate glass.
Borosilicate glass
Yes, glass doesn't resist to HF and other compounds of fluorine.
Bottles, Petri dishes, Erlenmeyer flasks, Berzelius flasks, graduated cyllinders, test tubes, funnels, glass crucibles, glass dishes, watch glasses, round-bottom flasks, distillation columns, condensers, volumetric flasks, weighting vials and many others.

The density of borosilicate glass is approx. 2,23 g/cm3.

Borosilicate glass
Pyrex (the traditional borosilicate glass Pyrex made by Corning before 1998) is safe for both applications. Avoid the more recent Pyrex made by World Kitchen. The January 2011 issue of Consumer Reports indicates that it is not safe.
Borostix are rectangular glass rods used in the borosilicate glass-art industry.
Yes, glass doesn't resist to HF and other compounds of fluorine.
There could be heavy metals and/or other toxic elements in the glass which could leach into the food.
Borosilicate glass is resistant to higher temperatures; this glass is used for chemical labware.
Bottles, Petri dishes, Erlenmeyer flasks, Berzelius flasks, graduated cyllinders, test tubes, funnels, glass crucibles, glass dishes, watch glasses, round-bottom flasks, distillation columns, condensers, volumetric flasks, weighting vials and many others.
Pyrex is borosilicate glass and like all glass does not absorb any chemicals.
Glass types are named after the fluxes that are used to lower the melting temperature of the grains of silica sand. Borosilicate, therefore, contains boron, or a derivative, such as boric acid, or borax, to do this. Borosilicate glass is most often used for cookery or in laboratory apparatus, as it is very resistant to thermal shock and corrosion by acids.
