6418 



6418 SLIDE WARMER, Electric, to provide a convenient method of mounting 

 paraffin sections. The slides are heated slowly and evenly over their 

 entire extent to a temperature just below the melting point of the 

 paraffin, thereby giving maximum flattening without damage to the 

 specimen. Forty slides can be accommodated at one time. A ther- 

 mometer is placed just below the block of transite and registers a 

 temperature somewhat lower than that on the surface. With paraffin 

 of 55 the best results are obtained when the regulator is set to main- 

 tain a thermometer 'temperature of 43. The slides are protected 

 from dust while drying by a metal hood which is placed over the 

 apparatus. With this slide warmer drying is cut down from 24 hours 

 at room temperature to 2 or 3 hours at a temperature just under the 

 paraffin melting point. Price, complete.. $35.00
