Purpose

 - The TBS Solvent Recovery System was manufactured for the purpose of recovering solvents used 

within the laboratory setting.   Many laboratories now use the TBS equipment for recovering solvents such 

as xylene and graded alcohols.   (See List of Acceptable Distillation Solvents in this manual)   In the average 

size laboratory, the recovery of these two solvents have proven to have saved thousands of dollars each year 

as well as protecting the environment from toxic chemicals being stored and/or transported.   In addition, 

laboratories have decreased their cost of hauling hazardous waste off sight as well as the undesirable, 

regulatory, responsibilities that go along with that waste removal. 

 

NOTE:  When handling chemicals, use gloves, safety glasses with splash guard and an apron. 

 

 
Procedure for Recovering: 
 
Alcohol: 
 

 

1.   Place clean and dry collection containers under each of the lower distillate solvent outlet nozzles left and 

right. 

 

2.   Verify that the Thermal oil level is at the correct level. 
 

3.   Place the disposable plastic bag into the vessel using the expandable metal ring to hold the bag in place.   

Note: For the 3-gal unit, small hole should be cut near the top edge of the bag to fit over the vapor 

collection duct. 

 

4.   Place the contaminated solvent in the distilling chamber, up to 3 gallons.   

  
NOTE

: Take special care NOT to allow any contaminated solvent to enter the Vapor Collector Duct    

Manifold when you are filling the distilling chamber.   This may create a build up of wax inside of the    

condensing coils that can cause blockage and unwanted pressure within the distilling chamber during  

recovery. 

 

5.   Close the cover of the chamber by securing the locking knob by tighten clockwise until the knob stops.   

The spring will act as a release valve if an unlikely blockage of the vapor collector duct occurs.  

 

 

6.   Set the distillation temperature with the Working Thermostat 15°C above the boiling point of the 

contaminated solvent to be recovered. 

 

7.   Setting of the fractional temperature depends on the solvent you are recycling. You should then set the 

fractional temperature at approximately 20-30°C higher than your highest boiling point of the 
contaminates.   Alcohol has a boiling point of 78°.  Your fractional temperature switch will be set at a 

minimum of  85°C for the recovery of alcohol. 

 

8.   Set the timer for distillation.   For a full distilling chamber it will take 5-6 hours for complete distillation 

to be accomplished.   This may vary with the solvent.   Alcohol, for example, may take up to 6 hours.   

The final results will not be effected and the unit will not be damaged if you over set the timer.   NOTE: 

When you wish to recycle alcohol (boiling point of 78°C), it is necessary to change the temperature of
