What’s the difference between distilled and deionised water?
“Pure” water is used in all types of laboratories for a range of uses – from making up calibration standards to cleaning and even in the rinse cycle in some laboratory glasswashers for a pure clean. There are different types of purified water available – but what is the difference? Distilled water Distilled water is simply made by heating water to evaporation, then ...

Brackish water treatment for reuse using vacuum membrane distillation process
The availability of fresh water is vital for all human activities and in particular for improving living conditions, health and overall well-being. Pressure on scarce fresh water resources can be reduced by treating and reusing brackish water by advanced membrane treatment technologies. In this study, brackish water originating from effluent discharge of a local coal mine, seawater, groundwater ...

All you Need to Know About Membrane Distillation: Applications, Filters, and Lab Setup
What is Membrane Distillation? Membrane Distillation (MD) is a relatively new and promising separation technology that is an alternative to more energy intensive methods such as reverse osmosis or distillation. MD is a thermally driven process where only vapor molecules transfer through a hydrophobic (water repellent) microporous membrane. A typical membrane distillation ...

Determination of Aromatic Hydrocarbons in Diesel Fuel by LC-RID According to ASTM D6591
The test method presented here is applicable to the determination of mono-, di-, and tri-plus aromatic hydrocarbon (MAH, DAH, and T+AH, respectively) content in diesel fuels and middle distillates with boiling points in the range of 150° to 400° C in accordance with ASTM D6591. The accurate determination of the aromatic content of fuels is critical to assessing their quality and combustion ...

Borosilicate Glass: A brief history
From the laboratory standpoint, there are three main tyeps of glass used today; borosilicate, quartz and soda lime or flint glass. What is borosilicate glass, how is it different from other glasses, and why is it used so widely in laboratory research? The formation of glass and glass products goes back to the beginnings of recorded history. The invention of borosilicate glass is usually credited ...
