Gooch Crucible

Product Code : SCL-LG-11985

Gooch Crucible (SKU SCL-LG-11985) is a filtration vessel that collects a precipitate so it can be washed, dried and weighed in the same container during gravimetric analysis. It suits college and university chemistry, research laboratories and quality-control rooms wherever a solid must be separated from a liquid and measured by mass. From its base in Ambala, Haryana, Science Lab Supplies quotes and dispatches the crucible for teaching laboratories, testing rooms, tender contractors and distributors.

Specifications

The Gooch crucible's specifications are split into single rows below. In short, it is a gravimetric crucible with a filtration base, porous, fritted or perforated depending on construction, that lets the liquid drain while the precipitate stays behind; material, capacity, pore grade and heating limit are named on the quotation.

Applications and Experiments for the Gooch Crucible

A Gooch crucible is chosen when a precipitate has to be caught, washed and brought to constant mass without being transferred between vessels, which keeps losses low in quantitative work. It fits college analytical chemistry, pharmaceutical analysis and residue determinations in testing laboratories.

• B.Sc. and M.Sc. chemistry: gravimetric estimations in which a precipitate is filtered, washed, dried and weighed.
• B.Pharm pharmaceutical analysis: practical introduction to gravimetric methods.
• Quality-control work: finding the mass of an insoluble residue.
• Teaching precipitation, filtration and mass determination as one sequence, for example with the Equipment for Vacuum Filtration set.

Bring the empty crucible to constant mass first, seat it in the filtration set-up with Rubber Stoppers with Holes where needed, filter and wash, then dry, cool and reweigh. Lift it hot only with Crucible Tongs.

Standard Scope of Supply

One Gooch Crucible is supplied per unit ordered. Filter mats, adapters, suction flasks, a vacuum source, stands, tongs and a desiccator are not included; they can be requested alongside the crucible so the whole filtration train is priced on one quotation.

Packing, MOQ and Lead Time

A single crucible and a laboratory stock of dozens are quoted the same way: send the quantity and you receive packing details, delivery time and price for that order. As a chemistry lab instruments supplier, Science Lab Supplies can also place desiccators, funnels and weighing bottles on the same quotation.

Science Lab Supplies is a registered exporter with an Importer-Exporter Code and is able to ship to buyers in Vietnam, Malaysia, Peru, Egypt, Iraq and Nigeria. Gravimetric labs can list crucible quantities on the contact page or in the enquiry cart, while bids for institutions are covered on the lab tender page.

Frequently Asked Questions

What is a Gooch crucible used for?
It holds back a precipitate during gravimetric analysis so the solid can be washed, dried and weighed in one vessel. The mass of the precipitate is then used to calculate the amount of the substance being estimated.

Can it be used with vacuum filtration or heated?
Suction filtration and drying are possible with Gooch crucibles, but the limits depend on the material and filtration base. Check these for the model on your quotation before applying vacuum or heat.

Are a filter mat or suction flask included?
No. Only the crucible is supplied. A filter mat, adapter, suction flask, vacuum source, tongs and desiccator must be arranged separately or added to the same order.

Who supplies the Gooch Crucible?
The crucible comes from Science Lab Supplies in Ambala, Haryana, which sends it to teaching and testing laboratories and to contractors buying for them, and can combine it with other gravimetric and filtration glassware on a single quotation.

Related Gravimetric, Filtration and Weighing Items

Gravimetric work runs as a chain: filtering the precipitate, handling the hot crucible, cooling it away from moisture and weighing it accurately. The items below cover each of those steps and alternative filtration routes, so a teaching or testing bench can be equipped from one enquiry.
