White Glazed Finished Al2O3 Porcelain Reaction Spot Plate for High-precision micro-scale Chemical Experiments

White Glazed Finished Al2O3 Porcelain Reaction Spot Plate 

Product Description

Renowned for its precise micro-reaction capabilities, clear visual contrast, and excellent chemical stability, the Porcelain Spot Plate is a classic choice for qualitative chemical analysis. These plates are available in two material types—standard laboratory porcelain and 95% high-purity alumina—and come in various configurations, such as 2-well, 6-well, and 12-well versions. The dense, non-absorbent glaze prevents reagents from seeping into the ceramic body, thereby eliminating the risk of sample cross-contamination. The 95% alumina version offers superior hardness and minimal impurity leaching, making it suitable for high-precision micro-scale chemical experiments; durable and easy to clean, it serves as an ideal laboratory consumable for parallel comparative testing.

Product Structure

The ceramic reaction spot plate is manufactured using an integrated molding process, resulting in a simple yet practical design:

1. Base Body: a rectangular or nearly square ceramic plate of moderate thickness, ensuring a stable grip.
2. Reaction Wells: the surface features 2–12 evenly distributed circular wells (cavities); the depth and diameter of these wells are precisely engineered to ensure thorough reagent mixing while minimizing the risk of splashing.
3. Glazed Finish: the surface and the inner walls of the wells are glazed, creating a smooth, dense, and chemically inert finish that is easy to clean.
4. Edge Design: the edges are smooth and flat, facilitating easy handling and stable placement on the laboratory bench.

Product Features

1. Dual-color design for clearer experimental observation

    available in two color options:

    white spotting plate: suitable for observing color-forming reactions; colored products stand out against the white background, facilitating easy interpretation.

    black spotting plate: Suitable for detecting white precipitates; white precipitates are clearly visible against the black background, preventing missed detections.

2.High-quality ceramic material with exceptional chemical stability.

   manufactured from high-purity porcelain clay and fired at high temperatures, the vessel features a glazed surface that offers excellent resistance to acid and alkali corrosion. It is safe for contact with various inorganic acids, alkalis, and organic solvents, ensuring that experimental results remain unaffected by the vessel itself.

3.Smooth, easy-to-clean, and reusable glazed surface.

   the smooth glaze resists chemical residue; after use, it can be cleaned with water or a mild detergent. It is suitable for repeated use, making it both economical and eco-friendly.

4.Multi-well layout for efficient parallel experimentation

    a single plate integrates multiple reaction wells, enabling simultaneous parallel or control experiments; this significantly boosts experimental efficiency while saving on reagents and time.

5.Micro-scale reactions to conserve reagents

    each well requires only a few drops of reagent to complete the reaction, making it ideal for the analysis of precious samples or expensive reagents.

6.Rugged, durable, and long-lasting.

    the ceramic material offers high mechanical strength and resists breakage under normal use, ensuring a long service life in various laboratory environments.

Technical Specifications

Size reference: The 2-well plate is compact and portable, suitable for rapid testing of small sample quantities; the 6-well plate is a standard specification for educational experiments, balancing efficiency with working space; the 12-well plate is suitable for high-throughput screening or experiments involving multiple control groups.

Typical Application Scenarios

1. Qualitative analysis experiments: color-forming and precipitation reactions, such as ion identification and functional group detection
2. Educational demonstrations: micro-scale experimental teaching in secondary school and university chemistry classes
3. Pharmaceutical testing: rapid screening of drug ingredients and detection of impurities
4. Environmental monitoring: qualitative detection of target substances in water quality samples and soil extracts
5. Food testing: rapid colorimetric analysis of food additives and heavy metal ions
6. Forensic analysis: rapid on-site detection of trace evidence, such as bloodstains and toxic substances

Instructions for Usage

1.Select Color: choose a white or black spot plate based on the color of the sample being tested.

2.Add Reagents: use a dropper to add the test solution and the detection reagent into the same well.

3.Observe Reaction: gently shake or stir to mix the reagents; observe any color changes or precipitate formation.

4.Record Results: compare with a standard color chart or record the observed reaction phenomena.

5.Clean and Store: clean promptly after the experiment; allow to air dry, then store in a dry, well-ventilated area.

Precautions

1. Do not heat directly: the ceramic reaction plate is designed for micro-scale reactions at room temperature; do not place it directly on an alcohol lamp or hot plate.
2. Avoid rapid temperature changes: although the ceramic material is heat-resistant, sudden temperature fluctuations may cause cracking.
3. Gentle cleaning: use mild detergents; avoid highly corrosive cleaners or hard brushes that could scratch the glazed surface.
4. Storage: store in a dry, well-ventilated area away from direct sunlight, and avoid impact with sharp or hard objects.
5. Well identification: when conducting experiments with multiple wells, it is recommended to label them to avoid mixing up reagents.
