What Is the Porcelain Boat Used For?
A combustion boat is a shallow, elongated tray that slides a weighed solid sample into a combustion tube or furnace, where the sample is heated, burned or ignited and either the residue or the gases given off are measured. Typical uses are the combustion method for estimating carbon and hydrogen in organic compounds, taught in senior-secondary and college chemistry, and igniting small samples of minerals, soils or foods to find their ash content or loss on ignition in teaching and research labs. Because the boat is weighed before and after heating, it suits gravimetric work where the sample is only a few milligrams.
Before a gravimetric run, ignite the empty boat, let it cool in a desiccator and weigh it until the mass is constant. Load and unload it with crucible tongs or a hook, never by hand when hot. Porcelain resists high heat but can crack under sudden temperature change, so raise and lower the temperature gradually and never set a hot boat on a cold or wet surface.
What to Specify When Ordering
- Size — the listing gives no dimensions, so state the length or sample capacity you need and the bore of your combustion tube or the furnace opening the boat must fit.
- Working temperature — confirm that your method stays within the listed limit of 1500 °C.
- Quantity — the minimum order is 10 boats; labs running repeat ignitions usually keep spares, since porcelain can chip or crack.
- Handling items — crucible tongs, crucibles and pipe clay triangles are separate items that can be added to the same enquiry.
Frequently Asked Questions
What is a porcelain boat used for?
It holds a small solid sample while it is heated in a combustion tube or furnace. It is used for microanalysis such as carbon and hydrogen estimation, ash content and loss on ignition in school, college and research labs.
What temperature can this porcelain boat withstand?
Up to 1500 °C, as listed. Heat and cool it gradually, because a sudden change of temperature can crack porcelain even below that limit.
Is the boat glazed?
No. This boat is unglazed. If your method calls for a glazed surface, mention it in your enquiry and JLab will confirm what it can supply.
What size is the boat?
The listing does not give dimensions. Send the length or sample capacity you need, and the inside diameter of your combustion tube, so the quotation matches your equipment.
How is a combustion boat different from a weighing boat or a crucible?
A weighing boat, such as the JLab polystyrene weighing boat, is a disposable dish for weighing at room temperature and is not meant for heating. A crucible is a deeper cup, often with a lid, heated on a triangle or in a muffle furnace. A combustion boat is shallow and long so it can slide into a tube.
What information is needed for an export quotation?
Send the quantity and size, the destination country and port or city, the delivery terms you prefer (for example FOB or CIF), packing or labelling needs, and any tender reference.
Who manufactures this porcelain boat?
JLab, the trading name of Jain Laboratory Instruments Pvt Ltd, makes it at its works in Ambala, Haryana, India, and quotes for it directly as the manufacturer.
OEM Manufacturer
JLab is the trading name of Jain Laboratory Instruments Pvt Ltd, a chemistry lab equipment and porcelain ware manufacturer in India, incorporated in 2017 and based on Hargolal Road, Ambala, Haryana. Porcelain boats are made at JLab’s own works rather than bought from a trader, so schools, colleges, research labs, dealers and importers buy them factory-direct, each boat is visually inspected before dispatch, and repeat orders are handled by the manufacturer. The company holds MSME Udyam registration UDYAM-HR-01-0003849 (manufacturing enterprise) and Importer-Exporter Code 3317504552. JLab exports worldwide and ships to buyers in every region, for example Iceland in Northern Europe, Egypt in North Africa, Lesotho in Southern Africa, Serbia in Southern Europe and Belize in Central America and the Caribbean. Tender buyers can find details on the JLab lab tenders page.
