Blow Pipes
Whatsapp Order
Blow Pipes are slender, tubular instruments used to direct a focused stream of air or gas onto a flame to increase its temperature and precision during chemical, metallurgical, or glasswork operations. Constructed from heat-resistant metal or glass, blow pipes are essential tools in laboratory flame tests, small-scale metal soldering, glassblowing, and analytical chemistry for identifying elements through flame color reactions. Their simple yet efficient design enables precise flame control and directional heating, critical for both qualitative analysis and delicate manual fabrication tasks.
