Graphite is widely used in the laboratory industry due to its exceptional properties, including high thermal and electrical conductivity, chemical resistance, and mechanical strength. It is a crucial material for various laboratory applications where extreme temperatures, corrosive environments, and high precision are required.
Graphite efficiently conducts heat, making it suitable for use in high-temperature applications like crucibles, electrodes, and furnaces.
Graphite remains stable at extremely high temperatures (melting point ≈ 3,927°C or 7,100°F), making it suitable for heat-intensive environments.
It is highly resistant to many chemicals, including acids, alkalis, and organic solvents, which ensures durability in corrosive environments.
Graphite has natural lubricating properties, which reduce friction and wear in moving parts, such as seals and bearings in lab equipment.
It is an excellent conductor of electricity, used for electrodes in electrochemical experiments and arc furnaces.
Graphite can withstand rapid temperature changes without cracking, which is essential for lab crucibles and other thermal cycling applications.
1. Graphite Crucible Used in Chemical Analysis
Crucibles are used in various fields of science and industry, including chemistry, metallurgy, and materials science. They are essential for conducting high-temperature reactions, melting metals, and analyzing substances with high accuracy. Crucibles can withstand temperatures of up to 2000 °C and are made from materials that can withstand extreme heat and chemical reactions. Graphite is an excellent choice for high-temperature applications and is resistant to thermal shock, making it ideal for chemical analysis.
Laboratory graphite crucible is used to analyze chemical samples, it can withstand high temperature, corrosion resistance without affecting the analysis result, so it has been widely used in chemical analysis. We produce high-quality, high-density graphite crucibles for inert gas fusion combustion analysis using only the highest quality graphite and manufacturing tools.
Our graphite crucibles have been tested over time to stand up to even the most difficult analysis. From the difficult-to-analyze titanium and zirconium to simpler applications like copper and steel, we always have a graphite crucible to meet your needs and quality control measures. We offer graphite for all major OEMs including LECO®, ELTRA®.
2. Graphite Crucible for Aluminum Vacuum Evaporation Coating
The graphite cruicbles are specially used for aluminum coated film production under vacuum condition. Quality of graphite crucible will greatly affect film quality and production cost. Vacuum evaporation aluminum coating is a process under vacuum condition to coat aluminum onto film substrates to form a composite film. Such as substrates as BOPET, BONY, BOPP, PE, PVC, direct evaporation transferring process usually applied. The vacuum evaporation aluminum coating process requires high quality graphite crucible, and we are capable of stable and quality supplying.
3. Graphite digester is an instrument used in chemical analysis laboratories.
The graphite digester is an instrument used in chemical analysis laboratories. It can transform complex samples into forms that are easy to analyze, thereby assisting chemical analysts in precise quantitative and qualitative analysis.
Graphite digester is commonly used for metal analysis, especially for metal elements in solid samples. It can decompose metal samples into ionic forms for accurate measurement using spectroscopic instruments.
The graphite digester can also be employed for the analysis of organic substances. For instance, it can break down organic compounds in organic samples into ions or gases for analysis methods such as gas chromatography or liquid chromatography.
In addition, the graphite digester is also widely used in industries such as food, medicine, environmental protection, and chemical engineering, for the dissolution treatment of samples like feed, food, and ores before chemical analysis.
Characteristics of graphite digestion instrument:
1. High efficiency digestion of large batches of samples, capable of digesting 36, 56, and 72 samples in one time.
2. The parallelism of the sample is better, and the wrapping type is uniformly heated, with a temperature difference of ± 1.5 ° C during sample heating
The graphite digestion instrument uses high-purity graphite material as the heating element, with wrapped heating, good temperature uniformity, and high efficiency; Porous design for easy batch processing of samples.
