Retort Clamp Special 4-Prongs
Retort Clamp Special 4-Prongs (Product Code: SLE/RC/05) is a four-finger stainless steel laboratory clamp used to hold larger or heavier round vessels, such as big flasks and wide columns, firmly on a retort stand. Made from 18/10 stainless steel with silicone-coated fingers and a 12 mm shaft, it comes in three sizes with spans of 0–120 mm, 20–100 mm or 50–150 mm. It is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM, at its own factory in Ambala, India.

What Is the 4-Prong Special Retort Clamp Used For?
A fourth finger spreads the holding force around more of the vessel, so the clamp resists tilting when it carries a large round-bottom flask, a wide chromatography column or a full separating funnel. The 150 mm size with a 0–120 mm span covers everything from narrow necks to mid-sized bodies, while the two 190 mm sizes reach further from the rod and are set for mid-range (20–100 mm) or wide (50–150 mm) vessels.
Silicone-coated fingers keep metal off the glass and add grip on smooth surfaces. For heavy loads, mount the clamp low on the support rod, tighten the bosshead fully before adding liquid, and keep the coated fingers clear of direct flame. Checking the stand for wobble before starting a long run is a good habit in any teaching or research lab.

Frequently Asked Questions
What sizes does the Retort Clamp Special 4-Prongs come in?
The Retort Clamp Special 4-Prongs comes in three sizes, all with a 12 mm shaft: 150 mm long with a 0–120 mm span, 190 mm long with a 20–100 mm span, and 190 mm long with a 50–150 mm span.
Why choose a 4-prong clamp instead of a 3-prong clamp?
A 4-prong clamp such as the Retort Clamp Special 4-Prongs grips a vessel at four points instead of three, spreading the load and resisting tilt, which helps with large flasks, wide columns and other heavy or top-heavy apparatus.
What are the fingers of the Retort Clamp Special 4-Prongs coated with?
The fingers of the Retort Clamp Special 4-Prongs have a silicone coating over the 18/10 stainless steel. The coating cushions glass and improves grip on smooth surfaces, and it should be kept away from direct flame.
