What Is the Zinc Boss Head Used For?
Every clamped set-up on a retort stand depends on boss heads. Fixed on the upright rod, a boss head carries the stem of a burette clamp, condenser clamp, extension clamp or support ring and can be moved up or down to set the working height. With several on one stand, a funnel, a burette or a condenser can be held together for filtration, titration or distillation in chemistry practicals at school and college level. Die-casting gives the zinc alloy a precise, repeatable shape, and its softening point of 250 °C is a temperature that a burner flame can easily exceed.

- Model — this die-cast zinc boss head or one of the aluminium, iron or powder-coated models.

OEM Manufacturer
JLab is the trading name of Jain Laboratory Instruments Pvt Ltd, a manufacturer of stand fittings, clamps and chemistry lab equipment in India, incorporated in 2017 and based on Hargolal Road, Ambala, Haryana. The zinc boss head is cast and finished at JLab’s own works rather than bought from a trader, so schools, colleges, dealers and importers buy it factory-direct.
