High Vacuum Stopcocks, Double Oblique, Borosilicate Glass
Product Code : JA-SCSAS-1668
High Vacuum Stopcocks, Double Oblique, Borosilicate Glass (product code JA-SCSAS-1668) are switching taps for glass vacuum manifolds. The high vacuum double oblique stopcock has two angled bores in a glass key, so each port can be switched between two lines, typically vacuum and an inert gas, or closed. The borosilicate barrel and glass key are made for secure operation on lines under vacuum. Two bore sizes are listed, 2 mm and 4 mm, for research and advanced teaching laboratories.
Specifications
These stopcocks have a borosilicate glass barrel and a glass key with a double oblique bore, listed in 2 mm and 4 mm bores. A straight-through high vacuum version with a key-retaining device is listed separately.
