Details
Authentic, old-school Sheldon Black beaker tube from the era that helped define modern American scientific glass.
This piece features the classic black Sheldon Black label and the iconic beaker silhouette that made the brand highly sought after among collectors.
American-made from thick, high-quality borosilicate glass, this tube includes its original removable 8-arm diffusion downstem crafted from black glass, paired with an 18mm ground glass joint—a signature setup seen on early Sheldon Black production. The clean welds, balanced proportions, and substantial glass thickness reflect the craftsmanship and durability the brand is known for.
Early Sheldon Black beakers with original components are becoming increasingly difficult to find, especially examples featuring a black glass diffusion downstem. A true piece of American glass history and an excellent addition to any serious scientific or vintage glass collection
