What Is the Retort Stand Ring Used For?
The ring turns a retort stand into a support for apparatus that rests rather than being clamped. In filtration — for example separating sand from a salt solution in class 9 science — it holds the filter funnel over a beaker; over a burner it carries a wire gauze for heating a beaker or evaporating dish, or a clay triangle holding a crucible; and in extraction work it can support a separating funnel. The boss-head version clamps straight onto the stand rod, while the version on a stem is mounted through a separate boss head.
Because the ring is closed, apparatus is lowered into it from above rather than slipped in from the side, so set the ring height before placing the funnel or gauze. Keep the ring and stand clear of the flame when heating anything other than the gauze, and allow it to cool before you adjust it.
What to Specify When Ordering
- Version — the 75 mm ring with boss head, or the plated mild steel ring on a 140 mm stem (70 mm internal diameter), and how many of each.
- Quantity — the minimum order is 10 units; schools usually plan one ring per stand used for filtration or heating.
- Your stand rods — give their diameter so JLab can confirm the boss-head fit.
- Matching items — boss heads, gauzes and clay triangles can be added to the same enquiry.
Frequently Asked Questions
What sizes is this ring listed in?
Two. The ring with boss head has a 75 mm ring diameter; the ring on a rod has a 70 mm internal diameter and a 140 mm stem.
What is the difference between the two versions?
The boss-head version fixes directly to the retort stand rod. The stem version is a plated mild steel ring on a rod, which you mount on the stand with a separate boss head; its stem diameter is not stated, so check it against your boss heads.
What is the ring made of?
The ring on a rod is plated mild steel. The listing does not give the material of the boss-head version, so ask JLab if this matters for your lab.
Can the ring hold a separating funnel or a crucible?
Yes, as a support. A separating funnel can rest in the ring, and a crucible is held on a clay triangle placed on the ring over the burner.
Is the retort stand included?
No. This listing covers the ring only; the stand rod, base and boss heads are separate items.
What should an export enquiry contain?
The version and quantity, the destination country and port or city, delivery terms such as FOB or CIF, any packing or labelling instructions, and a tender reference where one applies.
Who manufactures this ring?
JLab (Jain Laboratory Instruments Pvt Ltd) makes it at its works in Ambala, Haryana, India.
OEM Manufacturer
JLab is the trading name of Jain Laboratory Instruments Pvt Ltd, a maker of school and college lab equipment in India, incorporated in 2017 and based on Hargolal Road, Ambala, Haryana. Stand fittings such as this ring are produced at JLab’s own works rather than resold from a trader, so schools, colleges, dealers and importers buy factory-direct, every ring is visually inspected before dispatch, and repeat orders go back to the same manufacturer. JLab exports worldwide and ships to buyers in every region — for example Brazil in South America, El Salvador in Central America and the Caribbean, Bhutan in South Asia, South Korea in East Asia and Latvia in Northern Europe. Tender information is on the JLab lab tenders page.
