Pyrex RodFor nearly seventy years, Macalaster Bicknell Company of New Jersey has been a preferred supplier of Pyrex rod, tubing and high tech glassware. Our extensive inventory of borosilicate glass products can be used in a variety of industries, including lampworking, pharmaceutical packaging and laboratory applications.

Borosilicate Glass

Forged from a combination of boron trioxide and silica, borosilicate glass boasts a low coefficient of thermal expansion. This means that borosilicate has a higher resistance to thermal shock than common glass. This covetable property makes it an ideal material for laboratory glassware because it can withstand repeated heating and cooling without breaking down or cracking.

However, thermal shock resistance is also great for lampworking, and classifies borosilicate as a hard glass. This is because the glass melts at a higher temperature and shrinks slowly when cooling. Hard glass is considered more flexible to work with, and more forgiving than soft glasses, which tend to break easily if an even temperature is not maintained throughout handling.

Pyrex Tubing

Glass tubing is often used to join different pieces of scientific apparatus. The hollow tubes can be broken, bent and shaped to accommodate a versatile array of laboratory setups.

During the lampworking process, Pyrex tubing is ideal for creating hollow wares like vases and other containers. Borosilicate tubes are often colored with metal or silver, which can produce unpredictable patterns when heated with an oxygen flame.

Pyrex Rod

Pyrex rods are very similar to tubes in their cylindrical shapes and composition of borosilicate. However, the solid rods are most often used as stirring bars for titration in laborites. In lampworking, a colored Pyrex rod is used to create decorative solid pieces, like figurines, paper weights and goblets.

High tech glassware

In addition to Pyrex rods and tubing, Macalaster Bicknell Company of New Jersey also stocks a variety of beakers, bottles, flasks and funnels. From round bottom and Erlenmeyer flasks to reagent and media bottles, we have the scientific glassware you need for any application.
