Gooch Crucible

Product Code : SCL-LG-11985

The Gooch Crucible is a laboratory filtration vessel used for collecting, washing, drying, and weighing precipitates during gravimetric analysis. It is intended for chemistry laboratories, colleges, universities, research facilities, and quality-control environments where solid residues must be separated from liquids and retained for quantitative measurement.

Product Description

A Gooch crucible supports gravimetric procedures by retaining a precipitate while liquid passes through a porous, fritted, or perforated filtration base, depending on the specific construction. The collected solid can then be washed and, where the material and method permit, dried before weighing.

The exact material, capacity, pore grade, dimensions, and thermal limits of this Science Lab Supplies model have not been verified and should be confirmed before ordering. Buyers may also explore the chemistry laboratory equipment collection for related analytical and educational apparatus.

Key Features

• Designed for gravimetric analysis: Supports collection and quantitative handling of precipitates.
• Direct precipitate retention: Keeps the solid residue in one vessel for washing, drying, and weighing where the method permits.
• Filtration base: Exact porous, fritted, or perforated configuration.
• Laboratory workflow compatibility: May be used with suitable filtration accessories when required.
• Reusable format: Can be cleaned and reused when the material, sample, and method allow.
• Handling guidance: Hot crucibles should be moved with suitable crucible tongs.

Technical Specifications

What's Included in the Kit

• 1 × Gooch Crucible.
• Any filter mat, adapter, suction flask, vacuum source, stand, tongs, desiccator, or other accessory is not included unless specifically confirmed.

Applications / Uses

• Collecting precipitates during gravimetric chemical analysis.
• Washing retained solids without transferring them to another vessel.
• Drying a collected precipitate when the crucible material and method permit.
• Preparing residues for weighing after filtration and conditioning.
• Teaching quantitative analysis, precipitation, filtration, and mass determination.
• Working with compatible filtration setups and suitable laboratory flasks where required.

How to Use the Gooch Crucible

1. Inspect the crucible for cracks, chips, blockage, or contamination.
2. Clean and condition it according to the analytical method.
3. If constant mass is required, dry or heat the empty crucible only within verified material limits, cool it properly, and weigh it.
4. Place the crucible in the compatible filtration setup.
5. Transfer the precipitate-containing mixture and apply the required filtration method.
6. Wash the retained precipitate as specified.
7. Dry or heat the crucible and residue only when the confirmed material and analytical method permit.
8. Cool as required, then weigh and calculate the precipitate mass.

Safety note: Wear appropriate personal protective equipment. Avoid thermal shock and never apply vacuum, heat, or chemicals beyond the verified limits of the selected crucible.

Care & Maintenance

• Remove residues promptly with a cleaning method compatible with the crucible material and sample chemistry.
• Do not scratch or damage the filtration base.
• Avoid sudden temperature changes that may cause cracking.
• Store clean and dry in a protected location.

Frequently Asked Questions

What is a Gooch crucible used for?

A Gooch crucible is used to collect and retain a precipitate during gravimetric analysis so the solid can be washed, conditioned, and weighed according to the analytical method.

How does a Gooch crucible work?

Liquid passes through the crucible's filtration base while the solid precipitate is retained. The exact base type depends on the model.

What material is a Gooch crucible made from?

Gooch crucibles can be made from different materials depending on the design and intended method. The material of this specific Science Lab Supplies model is.

Can a Gooch crucible be used with vacuum filtration?

Some Gooch crucibles are used in compatible suction or vacuum filtration arrangements. Vacuum suitability for this specific model should be confirmed before use.

Is a Gooch crucible suitable for gravimetric analysis?

Yes. Gooch crucibles are commonly used for retaining precipitates in quantitative gravimetric procedures.

Can a Gooch crucible be heated?

Heating suitability depends on the crucible material, filtration medium, sample, and analytical method. Do not heat it until its material and temperature limits are confirmed.
