GENERAL INFORMATION 

 
The TBS Solvent Recovery System is designed for recovering solvents used in Histopathology with a boiling 
point between 50 - 180° C.  Using a closed system with  fractional distillation design, the Solvent Recovery 
System can be operated simply and safely. 
 
This Manual - Reading this manual is essential for correct and safe use of this equipment. 
 
Application - The TBS Solvent Recovery System will successfully and economically recover most solvents 
used for dehydration, extraction of fat and as an inter medium (Xylene, acetone, ethanol, toluene, etc.). 
 
Function - The waste solvents, distilland from tissue processors and/or tissue stainers, are heated inside the 
distillation vessel of the recycler, converted to vapor and then condensed back into a liquid.  A thermostat 
and a timer will control the process.  The vaporized solvent is directed through a collection pipe to an air 
cooled distilling condenser where the vapor is condensed back into liquid.  The distillate is then collected in 
a closed container on the outside of the unit. The recovery rate of the solvent will depend on the grade of 
contamination of the waste solvent being recycled. 
 
Separation Module - The TBS Solvent Recovery System utilizes the principle of Simple Distillation, 
however, it will achieve the results of Fractional Distillation using the Separation Module and Baffle.  The 
Switching Module allows an operator to set a fraction temperature at which the distillate of the different 
solvents will be separated.  The fraction temperature is set relative to the boiling point of the solvent you 
wish to recover.  This fraction temperature is easily set at the beginning of each  recovery cycle. 
 
Safety Measures - TBS Solvent Recovery Systems work ONLY with atmospheric pressure.  Should the 
thermal oil temperature exceed the maximum set value of the working thermostat by more than 25°C or if a 
defective cooling fan allows the distillate to emerge at a temperature higher than 40°C (104°F), the 
distillation process will be interrupted by a complete and total shut down of the unit.  The unit will shutdown 
if the Thermal Oil temperature exceeds 225°C. 
 
TBS solvent Recovery Systems have been extensively tested and approved by the ETL Testing Laboratories 

 

  

 
OPERATIONAL SAFETY 

 
General

 - TBS Solvent Recovery Systems adhere to ETL guidelines for safety and manufacturing. It is 

suggested that your laboratory purchase an appropriate fire extinguisher to be placed within ten feet of any 

electrically heated equipment. 

 

TBS recommends that the Safety Officer for your facility be contacted for proper storage and disposal of any 

hazardous substance being recycled. 

 
Location

 - It will be necessary for to contact the Environmental health and Safety Officer and the local fire 

marshal regarding placement recommendations for your Solvent Recovery System.
