Does a solvent recycler need ventilation?

No, B/R recyclers do not require special ventilation or a special room. B/R Solvent recyclers are closed systems – no special ventilation needed. B/R solvent recyclers are closed systems. The distillation process is safely contained inside the all metal recycler. There is no place for the solvent to escape, so no additional ventilation needed. Q: […]

Does Solvent Recycling Make Cents…Dollars?

Q: My boss wants our lab to start recycling solvents. How do I know if it makes financial sense? Solvent recycling saves money! That’s the main driving force for recycling. A common gauge of the cost savings is a payback analysis. This shows how long it will take before a recycler has paid for itself […]

How do I fill my recycler?

Q: How do I fill my recycler? Most recyclers have more than one way to fill them. You can choose the fill method that fits your lab. Direct fill – One pour and done! Directly filling the boiler is our favorite because it involves the least handling of the waste. If you weren’t recycling you […]

Recycled Solvent Purity Test

Q: How do I know my recycled solvents are pure? You can use the following quick tests to check the purity of the recycled solvents. Xylene: The Graduated Cylinder Test is a simple way to check xylene for alcohol impurities. Mix together 85 ml or xylene and 15 ml of water. If the water layer […]

Should recycled solvents smell fishy?

Q: I’ve heard some recycled solvents smell fishy. Is there a way to avoid that? Bad smelling solvent is an unpleasant problem but it’s easy to avoid. Waste solvent contains dissolved protein. During the recycling process protein get stuck to the sides of your boiler. Over time it builds up and starts to denature (decompose). […]

No Rinse Cycle

No Rinse Cycle

by brblog

Q: If I am recycling more than one solvent in a recycler, how do I avoid cross contamination between the solvents? After making your solvents nice and clean in the recycler, you don’t want to contaminate them with another solvent. There are two types of recyclers to consider, single and multiple path recyclers. Single path […]

Solvent recycling is great, especially if someone else does it for you

Solvent recycling in our lab? Sounds great but can’t somebody else do it for us? A growing trend in hospitals is for Environmental Health and Safety (EH&S) to recycle solvents for the Histology laboratory. Since EH&S is normally responsible for waste disposal, it makes sense for them to manage the recycling of used solvents. EH&S […]

How much does it cost to operate a Solvent Recycler?

With a 20 liter (5 gallon) recycler you can easily recycler 5000 to 10000 liters (1300 to 2700 gallons) of solvent in a year. Typical operating costs to recycle 10000 liters of solvent would be about $200, or about $0.02 USD per liter ($0.07 USD per gallon). It’s a great idea to understand all of […]

Fractional Distillation and Solvent Recycling

If you need consistent, high quality recycled solvents, you need fractional distillation. The good solvent and the contaminants have different boiling points. By paying attention to the boiling point (vapor temperature) you can separate the good (clean solvent) from the bad (contaminants). Here is an example of the fractional distillation of xylene. Choose: A solvent […]
