Description

Custom Quartz Combustion Weighing Bottle with Varies Dimensions

Quartz combustion weighing bottle is a commonly used laboratory vessel designed for precise weighing of solid or liquid samples. Its core uses include: High precision weighing: ensures the accuracy of experimental data in fields such as analytical chemistry, drug development, and materials science.
High temperature treatment: used for sample drying, burning, or high-temperature reactions, such as pre-treatment before thermogravimetric analysis (TGA).
Corrosive environment: Suitable for contact with strong acids, strong bases, or organic solvents (except hydrofluoric acid).

Material characteristics
High purity quartz glass (SiO ₂):
High temperature resistance: The softening point is about 1650 ° C, and the normal operating temperature can reach 1100 ° C, far exceeding ordinary glass (with a temperature resistance of about 500 ° C).
Chemical inertness: Resistant to most chemical corrosion except hydrofluoric acid (HF), high-temperature phosphoric acid, and strong alkali.
Low thermal expansion coefficient: Strong resistance to thermal shock and able to withstand rapid temperature changes.
High transparency: Excellent UV light transmission performance, suitable for experiments that require UV irradiation.

Structural characteristics
Sealing design: Grinding mouth cover (usually made of quartz or high temperature resistant material) ensures that the sample is moisture-proof and non-volatile.
Transparent bottle body: easy to observe the status of the sample, with a wide and flat bottom to enhance stability.
Diverse specifications: Capacity ranging from a few milliliters to hundreds of milliliters, suitable for different experimental needs.

Application scenarios
High temperature experiment: such as calcining samples in a muffle furnace and drying them in a drying oven.
Corrosive sample treatment: in strong acid environments such as concentrated sulfuric acid, nitric acid, etc.
Precision analysis: trace analysis in drug purity testing and environmental monitoring.

Precautions for use
Anti fall and anti-collision: Quartz material has high brittleness and needs to be handled with care.
Avoid hydrofluoric acid: Contact with HF can cause severe corrosion.
Cleaning method: Soak in dilute acid or neutral detergent, wipe with a soft cloth to avoid scratching by hard objects.
Temperature management: Avoid sudden cooling and heating. After using at high temperatures, naturally cool to room temperature before weighing.

Comparison with other materials
Ordinary glass weighing bottle: Low cost, but poor temperature and corrosion resistance, suitable for routine experiments.
Ceramic weighing dish: resistant to high temperatures but bulky and opaque, quartz has better transparency and lightness.
Plastic weighing container: not resistant to high temperatures and organic solvents, suitable for non corrosive ambient temperature environments.

Purchase and maintenance
Key points for selection: Prioritize high-purity and bubble free products to ensure experimental accuracy.
Price factor: Quartz has a high cost, it is recommended to use it selectively according to experimental needs.

Quartz combustion weighing bottles have become an indispensable tool in high-end laboratories due to their high temperature resistance, corrosion resistance, and chemical stability, especially performing excellently under harsh experimental conditions. Reasonable use and maintenance can extend its lifespan and ensure the reliability of experimental results.

Fused Quartz Glass Features:

Fused quartz glass is a special industrial glass made of silicon dioxide. It is a very good basic material. Quartz glass has a series of excellent physical and chemical properties.

1. High temperature resistance. The softening point of fused quartz glass is about 1730℃ and can be used for long time working under 1100℃~1250℃.  And working at 1450℃ in a short time.

2. Corrosion resistance. In addition to hydrofluoric acid, fused quartz glass is inert to other acids. Its acid resistance is 30 times as ceramic, 150 times as stainless steel. Especially, any other material cannot make a comparison with chemical stability of fused quartz at high temperature

3. The thermal stability is good. Thermal expansion coefficient is extremely small. And it can withstand severe temperature changes such that heating up to 1100℃ and putting it in normal temperature water will not crack.

4. The light transmittance is good. Quartz glass has good transmittance in the whole spectral band from ultraviolet to infrared. The transmittance of the visible light is above 95%. Especially in the ultraviolet spectrum band and the maximum transmittance is over 85%.

5. The electrical insulation performance is good. Resistance value of quartz glass equaling to 10000 times of ordinary glass. It is an excellent electrical insulating material and has good electrical properties even under high temperature.
