MADE IN USA – 8 Dram (1 oz / 30 ml) Clear Borosilicate Glass Vial with Black Phenolic Screw Cap

Reliable. Versatile. Perfect for Kaleidoscope Oil Cells.

This 8 Dram clear glass vial is proudly made in the USA from Type I borosilicate glass, known for its exceptional clarity, strength, and resistance to thermal expansion. It is an excellent choice for both oil-filled and dry kaleidoscope object chambers, delivering dependable performance and a clean, professional finish.

Borosilicate glass has a low coefficient of expansion, making it especially well-suited for holding mineral oil and suspended objects—ideal for leak-resistant kaleidoscope oil cells. The included black phenolic screw cap features a PP/PE liner for a secure seal. For best results, adding 1–2 wraps of white Teflon plumber’s tape to the threads creates an almost foolproof, leak-resistant seal.
