This paper reports and discusses the beneficial effects on the quality of electrospun polycaprolactone nanofibers brought about by pretreatment of the solvent with non-thermal plasma. Chloroform/dimethylformamide 9:1 (CHCl3:DMF 9:1) and pure chloroform were pretreated by a few minute exposure to the plasma generated by an atmospheric pressure plasma jet (APPJ).

How to remove DMF from the product? - ResearchGate

For 5 mL of DMF or DMSO, I use 5 X 10 mL of water during the aqueous wash. This should remove all of the DMF or DMSO. Then two aqueous washes to remove DMF: 1. 5% LiCl (aq) 2. 0.5 N HCl.

Need suggestions for a chemically-resistant vacuum pump .

We just killed another vacuum pump. We have slaughtered our old Welch belt-drive pumps and are now torturing several newer direct-drive pumps. Has anyone lately shopped around for chemically-resistant vacuum pumps which will give a very low ultimate vacuum, say less than 2-3 T? We need to remove lots of water and the occasional liter of DMF.

N, N -Dimethylformamide (DMF) is one of the most common xenobiotic chemicals, and it can be easily emitted into the environment, where it causes harm to human beings. Herein, an efficient DMF-degrading strain, DM1, was isolated and identified as Methylobacterium sp. This strain can use DMF as the sole source of carbon and nitrogen. Whole-genome sequencing of strain DM1 revealed that it has a .

Rotary evaporator - Wikipedia

Rotary evaporator - Wikipedia

Rotary evaporators are also used in molecular cooking for the preparation of distillates and extracts.. A simple rotary evaporator system was invented by Lyman C. Craig. It was first commercialized by the Swiss company Büchi in 1957. In research the most common form is the 1L bench-top unit, whereas large scale (e.g., 20L-50L) versions are used in pilot plants in commercial chemical operations.

The rotovap had a hot bath set at 75 °C, speed fixed at 80 revolutions per minute, cooling coil running with ice water, and was placed under vacuum until about 150 mL of the liquid (predominantly water) was collected in the trap. The process of adding 150 mL of DMF and removing 150 mL of liquid via the rotovap was repeated several times.

For one, you may not have that level of vacuum control to work with, or you might be relying on facility water for your coolant. Using the rule of 20 on an adjustable temperature scale works too. For example, if your vapor temperature is 30°C, you can set your bath 20°C higher at 50°C and your coolant 20°C lower at 10.
