FAQs of J Lawrence Smith Type Crucible:
Q: How should the J Lawrence Smith Type Crucible be used in laboratory furnaces?
A: Place the crucible with your sample inside the furnace, ensuring that the temperature does not exceed 1200C. Its flared rim makes placement and removal easy. The glazed surface allows for easy cleaning after use, and high resistance to leaks makes it suitable for repeated heating cycles.
Q: What advantages does the glazed porcelain surface provide?
A: The glazed surfaces (inner and outer, except the bottom) make the crucible chemically inert, preventing interference with samples. This finish also facilitates residue removal during cleaning, enhancing durability and maintaining sample purity.
Q: When is it recommended to use this specific type of laboratory crucible?
A: The J Lawrence Smith Type Crucible is ideal when processes require heating samples to high temperatures (up to 1200C) and where chemical resistance, low thermal conductivity, and reliable mechanical strength are needed, such as in analytical chemistry and metallurgical testing.
Q: Where can this laboratory crucible be used efficiently?
A: This crucible serves laboratories, research institutes, educational establishments, and industrial testing facilities. Its robust design makes it suitable for settings where repeated high-temperature use and precise analysis are routine.
Q: What process ensures the crucibles resistance to leaks and thermal shock?
A: Manufactured from high-purity porcelain and finished with a glaze on all surfaces except the bottom, the crucibles materials and design grant it excellent thermal shock resistance and a high degree of impermeability to liquids and gases.
Q: How can users benefit from choosing a reusable porcelain crucible?
A: Reusable porcelain crucibles offer cost-effectiveness, environmental benefits, and reliable performance across multiple experiments, reducing the need for frequent replacements. Their chemical inertness ensures consistent, uncontaminated results every time.
