The combined organic layers were dried on Na2SO4 and all volatiles evaporated in vacuo using a rotary evaporator. Un-purified 31.1 g brown/yellow oil. The oil was dissolved in heptane (100 mL) and stored the solution at 4° C. The formed crystals were filtered off and then dried on ...
of the gelchromatographic eluate. Further, centrifugal vacuum concentrators can automate the evaporation process. In comparison to rotary evaporators, they save time for the laboratory staff when running series of 4 or more samples. It is very important to supply permanently sufficient energy for the...
Each fraction was reduced from 40 to 7 ml using a rotary evaporator. Each fraction was analyzed by MALDI-TOF MS in the positive mode using a mass range of 500–4500 Da. Bacillaene compounds were not observed by MALDI MS, but were analyzed by electrospray MS in the positive and negative...
the chloroform was evaporated using a rotary evaporator set at 52 ℃ and 90 rpm for an hour. The resulting lipid film was rehydrated with 2 mL of PBS buffer, ultrasonicated to ensure detachment, and the suspension was set aside in a 10 mL EP tube. Separately, 5-Aminolevulinic acid (ALA...
The extracts obtained were later evaporated using a rotary evaporator to remove solvent and stored at −20°C. The oil samples were taken out of frozen storage before analysis, left static at ambient temperature for an hour, and then heated to 60 °C until they were totally melted. 2.5. ...
The alcohol was then separated from the mixture using rotary evaporator, and drops of acetic acid were added. The precipitate was transferred to a Teflon-lined stainless-steel autoclave and heated at 300 °C at 100 bars for 1 h to produce TiO2 aerogel. However, the second class of the ...
(200 g) were grinned and dried overnight at 40 °C, moisture content was determined. Oil was extracted with diethyl ether (500 ml) in a Soxhlet Apparatus at a condensation rate of 5 or 6 points per second for 6 h. The solvent was then evaporated to dryness using a rotary evaporator,...
The organic solution was concentrated/evaporated under reduced pressure in a rotary evaporator, or treated by silica gel column chromatography (elution with a mixture of petroleum ether and ethyl acetate) to obtain a substituted olefin product of satisfactory purity. Data and 1H NMR and IR ...
removed by using a rotary evaporator at a water temperature of 60° C., to obtain a latex of a copolymer rubber (solid content concentration of about 30 wt %). Then, in an autoclave, the latex of the copolymer rubber obtained as described above and a palladium catalyst (a solution ...
