These are 200 mm Crucible Tongs Full Stainless Steel Crucible Tongs for Laboratory Use Heavy SS Tongs. This is the best quality tong or Chimta in Bangladesh.

Crucible tongs are specialized tools designed for handling crucibles, which are containers used to heat substances to high temperatures in laboratories or metalworking environments. These tongs allow users to safely move or manipulate the crucible without directly touching it, protecting against burns or exposure to hazardous materials.

Key features of 200 mm Crucible Tongs:

• Made of materials like stainless steel to withstand high temperatures.
• Designed to securely hold crucibles of various sizes without slipping.
• Long enough to provide a safe distance from the heat source.
• They are essential in scientific experiments, metallurgy, and industries that involve high-temperature processes.
• Material: High-quality stainless steel (often Grade 304 or 18/8 spec) for high-temperature resistance and corrosion protection.
• Length: Approximately 200 mm (8 inches), providing a safe distance between the user and the heat source.
• Design Features:
  • Tips: Curved or serrated/corrugated tips to ensure a secure, non-slip grip on round crucibles.
  • Joint: Durable riveted joint for flexible movement.
  • Handles: Large finger openings for comfortable grip and better control.
  • Chemical Resistance: Unlike nickel-plated steel, Grade 304 Stainless Steel is inherently rust-proof throughout its structure, making it superior for use with corrosive chemical vapors and aqueous solutions.
  • Aperture: Most 200 mm tongs have a maximum jaw opening (aperture) of approximately 25 mm to 28 mm, making them ideal for small 50–250 mL crucibles. 

• Preheating: Before use, the tips should be slightly preheated to prevent the hot crucible from cracking due to sudden local cooling.
• Cleaning: Ensure tongs are clean and dry before storage to maintain the rust-resistant finish.
