Filtration Gooch Crucible

The Filtration Gooch Crucible is a laboratory filtration vessel used for collecting, washing, drying, and weighing precipitates during gravimetric analysis. It is intended for supervised chemistry, college, university, research, and analytical laboratory procedures where solid material must be separated from a liquid and retained for quantitative measurement.

Product Description

The STEMAids Filtration Gooch Crucible is intended for quantitative filtration and gravimetric analysis. A Gooch crucible uses a perforated or porous filtration base that allows liquid to pass while retaining the precipitate required for subsequent washing, drying, and weighing.

The ability to retain the solid in a single vessel can simplify gravimetric workflows and reduce unnecessary sample transfer. The exact STEMAids construction material, nominal capacity, filtration-base type, pore grade, dimensions, and thermal limits are [confirm].

Key Features

• Designed for gravimetric analysis: Supports quantitative collection and handling of precipitates.
• Integrated filtration base: Allows liquid to pass while retaining suitable solid particles.
• Reduced sample transfer: The collected precipitate can remain in the crucible during washing and subsequent processing where the method permits.
• Suitable for analytical workflows: Supports laboratory procedures requiring separation and measurement of insoluble residues.
• Reusable format: Can be cleaned and reused when compatible with the sample, filter structure, and crucible material.
• Compatible with controlled filtration: May be used with an appropriate filtration setup according to the crucible design.
• Critical specifications: Capacity, material, pore grade, and temperature limit are [confirm].

How to Use the Filtration Gooch Crucible

1. Clean and prepare the crucible according to the analytical procedure.
2. Dry and weigh the empty crucible to constant mass where required by the method.
3. Position the crucible in the appropriate filtration assembly.
4. Transfer the sample or precipitate suspension carefully into the crucible.
5. Apply gravity or suitable suction only if permitted by the crucible design and laboratory method.
6. Wash the retained precipitate with the specified wash liquid.
7. Dry or otherwise condition the crucible and precipitate according to the analytical procedure and confirmed material limits.
8. Cool as required, then weigh and calculate the mass of the retained material.

Safety note: Do not heat, ignite, or apply vacuum to the crucible unless its material and operating limits are confirmed. Handle hot crucibles with suitable laboratory tongs and follow the safety requirements for the sample and wash liquids.

Care & Maintenance

• Remove retained residues using a cleaning method compatible with the crucible material and filtration base.
• Do not scratch, probe, or mechanically damage a porous or fritted filtration surface.
• Inspect the crucible for cracks, chips, blocked pores, or filtration damage before use.
• Store clean and dry in a protected location to prevent contamination and impact damage.

Frequently Asked Questions

What is a Filtration Gooch Crucible used for?

A Gooch crucible is used to collect and retain precipitates during filtration, especially in gravimetric analysis where the solid must subsequently be washed, dried, and weighed.

How does a Gooch crucible work?

The crucible has a perforated or porous filtration base. Liquid passes through the base while suitable solid particles are retained inside the crucible.

Can a Gooch crucible be used for gravimetric analysis?

Yes. Gravimetric analysis is one of the principal uses of a Gooch crucible because the collected precipitate can be quantitatively processed and weighed.

Can the STEMAids Gooch Crucible be used with vacuum filtration?

[confirm]. Vacuum compatibility depends on the exact crucible construction, filtration base, adapter, and manufacturer’s operating specification.

What material is the STEMAids Filtration Gooch Crucible made from?

The material for this specific STEMAids model is [confirm]. It should not be described as porcelain, borosilicate glass, sintered glass, or another specific material until verified.

Can a Gooch crucible be heated?

Heating limits depend on the crucible material and filtration medium. Do not assume that this STEMAids model can be dried at high temperature or ignited until its thermal specification is confirmed.
