Combustion Tubes, of fused quartz (silica). 



It is acknowledged that fused quartz is the most suitable for combustion tubes. 



Such combustion tubes need not be of the more costly transparent material throughout ; it is sufficient 

 that the part of the tube immediately surrounding the boat be transparent, so that the progress of combustion 

 may be observed. 



Combustion tubes of opaque silica, with a short section of transparent silica tubing interposed, can now 

 be supplied. 



The standard pattern tube is 3 ft. long, having a 4-in. length of transparent tubing placed at a distance 

 of 12 in. from one end. 



The prices of these combustion tubes are

 experience to customers who require apparatus constructed to their own designs.
