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. Chemistry departments, university and research laboratories and quality-control rooms use it wherever a solid must be separated from a liquid and measured by mass. Science Lab Supplies sends it out from Ambala, India to schools, colleges, research institutes, tender contractors and distributors.

Specifications

The crucible has a filtration base through which the liquid drains while the precipitate stays behind; the base may be porous, fritted or perforated depending on construction. Material, capacity, pore grade and heating limit vary between versions, so the quotation names these for the model offered.

Applications and Experiments for the Gooch Crucible

A Gooch crucible is used 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 belongs in college analytical chemistry, pharmaceutical analysis and routine 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 laboratories: finding the mass of an insoluble residue.
• Teaching precipitation, filtration and mass determination as one sequence.

Bring the empty crucible to constant mass first, filter and wash as the method specifies, then dry, cool and reweigh. Move a hot crucible only with tongs and avoid sudden temperature changes.

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 full filtration train arrives together.

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, we 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. Questions and orders go through the contact page or the enquiry cart, and tender buyers can refer to 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 common 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 order.

Who supplies the Gooch Crucible?
Science Lab Supplies, based in Ambala, Haryana, supplies this crucible to teaching and testing laboratories, and to contractors buying for them. Quotations can combine it with other gravimetric and filtration glassware.

Related Gravimetric and Filtration Items

Gravimetric work depends on a chain of steps: filtering the precipitate, cooling it away from moisture and weighing it accurately. The four items below cover those steps and an alternative filtration route, so a teaching or testing bench can be equipped from one enquiry.

• Glass Desiccator — cools the dried crucible without it picking up moisture.
• Weighing Bottle — holds samples during accurate weighing.
• Borosilicate Filter Funnel — for gravity filtration with filter paper.
• Millipore Filter Apparatus — vacuum filtration through membrane filters.
