General purpose lab burner for propane and/or gas supplies Key benefits and features - Versatile laboratory heating source compatible with propane and/or gas inputs for general purpose use. - Energy-efficient operation with a design optimized for effective flame production. - Flexible tube configuration: supports both single-tube and dual-tube operation to suit different heating needs. - Independent flame control on each tube, allowing single-tube or dual-tube flame management as required. - Adjustable orientation: mounting or head rotation up to 30 degrees left or right to accommodate both left-handed and right-handed users and to optimize bench workflow. 2-3 practical use scenarios - Microscale heating and testing: use in a focused single-tube mode for precise heating of small glassware or samples, with flame orientation adjusted to fit tight bench spaces. - Two-sample heating or higher heat: switch to dual-tube operation to heat two samples simultaneously or to increase overall heat output when needed. - Tool preparation and sterilization: employ the burner for routine heating tasks such as sterilizing tools or preheating crucibles, selecting single or dual-tube flame as appropriate and positioning the flame for convenient access.
