Your Guide on Where to Buy Top-Rated Crucibles For High-Temperature Experiments
Temperature can impact several factors of a substance, from its stability and viscosity to its density and more. Higher temperatures can yield key findings. However, to achieve those temperatures, you need to have the best crucibles as a vessel.
Professionals must seek quality laboratory equipment to ensure safety and a higher success rate for their experiments. Here’s where you can buy top-rated crucibles for high-temperature experiments.

● MSE PRO High Purity Boron
● And more
2. Thermo Fisher Scientific
As a leader in scientific innovation, Thermo Fisher Scientific empowers customers to effectively perform advanced experiments by supplying technologies like crucibles that offer varying temperature resistance.
You can browse their inventory database by filtering for different materials like graphite, Inconel, nickel and more. You can also narrow your search by filtering through additional categories, such as shape, capacity or product type. Some products already come with a loose lid to ensure that gases can escape when heating.
Types of crucibles sold:
● Conical AI-23
● Cylindrical AI-24
● And more
3. Across International
ISO 9001:2015 certified manufacturer Across International creates heat treatment, laboratory and material processing equipment. While it has multiple addresses within the U.S., it also has a presence in Victoria, Australia.
This company’s main offering is the Graphite Crucible for Metal and Casting. Some units can handle up to 22 or 44 pounds of substances. However — for more heavy-duty production — you can get crucibles with a maximum casting capacity of 88 pounds.
Types of crucibles sold:
● Graphite Crucible for Metal and Casting
4. Growing Labs
The online distributor Growing Labs is another place where you can buy top-rated crucibles for high-temperature experiments. This supplier provides all kinds of laboratory equipment to the cultivation, analysis and extraction market.
The company’s crucibles are quite heat-resistant, taking on about 1700 degrees Celsius without cracking or warping. There are also more unique offerings, like porous-bottom crucibles. These are engineered with a molded-in porous disc for stable porosity.
Types of crucibles sold:
● High Alumina in Cylindrical Form
● Porcelain in Tall Form with Cover
● And more
Considerations When Choosing Crucibles
Understanding what kind of crucibles you should buy is a critical decision for laboratory professionals. Making temperature threshold a key consideration is a given, especially if you’re trying to melt or liquefy certain objects. These additional considerations should also be taken into account.
|
Material |
Material is one of the biggest factors to consider, as it dictates the efficacy of the crucible’s ability to contain your substance. Quartz and clay-graphite are among the most popular materials with high-temperature resistance. |
|
Size and shape |
Crucibles are available in all shapes and sizes. If you’re inhibiting, open-air, high-form vessels with a conical shape are ideal. However, if you require exposure, a more rectangular tray-like shape will work well. |
|
Thermal shock resistance |
Certain materials — like clay graphite — can handle extreme heat but are susceptible to breaking when exposed to high temperatures too quickly. As a result, you may want to use a more gradual heating process or pick a vessel with good thermal shock resistance. |
|
Compatibility |
The compatibility between your crucible and test substance should also be evaluated. For instance, porcelain can become brittle when exposed to liquids with a high acidic content, while nickel can contaminate certain chemicals while heating. |
|
Nature of the experiment |
Chemists may explore different heating methods and crucible placements. Gas torches are ideal for surface-level exposure. However, some people may opt to use a furnace and place the vessel right between the coals. |
|
Budget |
How much you’re willing to spend also matters. For instance, porcelain is one of the more affordable types of crucible on the market. However, it may offer minimal durability and limit your overall flexibility when experimenting. |
Where are Lab Crucibles Used?
Lab crucibles are versatile and can be used for many processes, from melting and combining different chemicals to testing the thermal reactions of other materials. Chemistry, pharmaceuticals and biotechnology are the main sectors that invest in the lab crucibles market and utilize crucibles for drug formulation and testing, food safety testing, material sciences, and more.
Safety When Running High-Temperature Experiments
While experiments are made to answer questions, you want to have enough information about how they work. Obtain documentation regarding the crucible’s properties and recommended usage. Running experiments at increased temperatures can increase the likelihood of fire or explosions. Make sure you’re doing them within a controlled environment.
Get the Best Lab Equipment
Learning where to buy top-rated crucibles for high-temperature experiments is just the first step to getting the equipment you need. Be selective with your containers to ensure that they can accommodate your intended application and minimize hazards.
