CRUCIBLE (Gooch)

The GISCOM Porcelain Gooch Crucible is a high-precision filtration crucible designed with a perforated bottom for efficient solid–liquid separation and gravimetric analysis. Its glazed inner and outer surface (except the rim and base) ensures chemical resistance, durability, and ease of cleaning. Widely used for total suspended solids (TSS) determination, residue testing, and analytical filtration, it delivers reliable, repeatable performance in research, QC/QA, and industrial laboratories.

Key Features

• Perforated bottom design for superior filtration efficiency
• Fully glazed interior and exterior (except rim and bottom) to resist chemicals and minimize contamination
• High thermal resistance, ideal for ignition, drying, and gravimetric evaluations
• Uniform pore arrangement for consistent and accurate solid retention
• Strong mechanical stability for repeated heating and cooling cycles
• Smooth, vitrified finish for easy sample removal and cleaning
• Compatible with filter mats, fiber pads, and standard filtration assemblies

Material Specifications

• Material: High-quality laboratory porcelain
• Thermal Properties: Suitable for temperatures up to 1000–1200°C. Excellent thermal shock resistance when heated gradually
• Chemical Properties: Resistant to most acids, salts, and reagents. Non-porous, vitrified body minimizes absorption
• Mechanical Properties: Rigid, impact-resistant structure designed for long-term laboratory use
• Manufacturing Standards: Produced under ISO 9001:2015 certified processes

Technical Specifications

• Available Capacities: Multiple volumes available (as per GISCOM standard range)
• Design: Straight-sided Gooch crucible with perforated base
• Glaze: Inside and outside glazed except the rim and bottom edge
• Tolerance: Consistent wall thickness; precision perforations
• Included Accessories: Compatible with porcelain or silica fiber filter pads (available separately)

Handling & Precautions

• Heat gradually to avoid thermal shock and extend crucible life
• Allow the crucible to cool naturally before washing or handling
• Use non-abrasive cleaning materials to protect the glaze
• Suitable for furnace, muffle furnace, and controlled heating equipment
• Avoid sudden temperature changes, direct flame, or quenching
• Store carefully to prevent rim or edge chipping

Applications

• Water and wastewater testing: Total suspended solids (TSS) and residue analysis
• Environmental laboratories: Filtration and particulate analysis
• Pharmaceutical QC/QA: Gravimetric residue, ash content, and purity tests
• Chemical and analytical laboratories: Filtration, drying, ignition, and mass determination
• Academic and research institutions: Teaching, training, and routine analytical procedures
• Essential in workflows requiring precise gravimetric filtration and solids determination
