Laboratory Platinum Crucibles are durable, have high resistance to chemical corrosion and able to cope with elevated temperatures up to 1200°C.

Dimensions - guide

• Diameter = 26mm.
• 
  
• Nominal capacity 10ml
• 
  
  Supplied in singles, natural finish.
  
  The above listing is a guide on resistance or otherwise of platinum crucibles, it’s not an exhaustive guide. Therefore we recommend any new or unknown compounds, heated for first time in your laboratory, a test is undertaken with a proven/old platinum crucible in first instance.
  
  Lids are available.
  
  Since this is a rare metal its subject to daily exchange and metal price fluctuations, please enquire at latest prices.

Platinum crucibles are soft at room temperature, deformation increases between 700°C - 1000°C as the temperature increases.

Recommended maximum process temperature 1200°C.

During heating and cooling platinum crucibles only handle or touch with either platinum tipped or ceramic coated instruments/surfaces.

Platinum crucibles can become damaged, decay or fail:

• with low melting point metals such as tin, antimony and bismuth.
• 
  
• using unknown compounds, heated for first time.
• 
  
• heating in presence of carbon yellow flame - always use oxygen rich oxidising flame.
• 
  
• when associated with following elements, silicone, lead, antimony and phosphorus, which may be airborne or nearby during heating.
• 
  
• with sulphur.
• 
  
• there are evaporation losses of platinum, even at room temperature a film of platinum oxide builds up, elevated temperatures oxidisation accelerates evaporating in use.
• 
  
• unnecessarily heating crucibles for long periods of time since this coarsens the grain structure leading to cracking and embrittlement.
• 
  
• when heated in furnaces the ceramic floor of the furnace must be free of contaminates and airborne contamination.
• 
  
• if heating a number in furnaces keep them apart to avoid fusing together.
• 
  
• placing near or directly on heating elements within furnaces.
• 
  
• handled with metallic objects such as tongs, tripods, meshes etc which are themselves not platinum.
• 
  

Cleaning

• Boil in solvent.
