Funnels. Our plastic lab funnels come in several varieties for laboratory appliions: Autoclavable funnels can be steam autoclaved and repeatedly used. Buchner funnels are economical and lightweight, perfect for typical lab use. Vial Funnels have internal screw threads that screw securely onto screw thread vials.

Fly Ash. Fly ash is a fine inorganic material with pozzolanic properties, which can be added to SCC to improve its properties. However the dimensional stability may be affected and should be checked. Silica Fume. Silica fume gives very good improvement of the rheological as well as the mechanical and chemical properties.

 · Before testing, a representative portion containing sufficient solids to be meaningful should be taken for solids concentration determination. The concentration is found by weighing the sample, filtering on a Buchner funnel fitted with two No. 1 Whatman papers, washing if necessary, drying at a suitable temperature and determine the net dry weight.

This research investigates the fresh behaviour and mechanical properties of selfcompacting concrete (SCC) containing high volume of limestone, metakaolin, silica fume, zeolite, and viscosity modifying admixture. Two fine aggregates with different fineness modulus were also utilized to evaluate the effect of sand's gradation on the mechanical and flow properties of SCC containing inert and ...

Fly ash from the flue gas of a power plant has to be removed before the gas is sent to an analyzer. Design a cyclone separator for cleaning the flue gas containing fly ash with the following size distribution: Size(microns) <5 510 1020 2030 3040 4050 >50 Wt % 15 19 24 14 8 5 15

using buchner funnel to give a coloured solution. The filtration process was repeated for full pigment recovery. The extract was centrifuged at 6000 rpm for 15 minutes at room temperature and supernatant was collected for the determination of total phenolic and total flavonoid content, and betacyanin content. Total phenolic content (TPC)

 · Fly ash. An ASTM Class F fly ash from Alberta, Canada was used. Its physical properties and chemical compositions are presented in Table 1 as well.. The fly ash meets the general requirements of ASTM Class F ash, has relatively high CaO content of % and alkali content (Na 2 O equivalent) of %. The Blaine fineness of the ash is 3060 cm 2 /g and the specific gravity is

The Post Reaction Workup: This post assumes you have just completed an HI reduction of ephedrine or pseudoephedrine to methamphetamine. Perhaps you arrived here by the use of red phosphorous and iodine, whether by pushpull, balloon, or reflux methods; by hypophoshorous acid and iodine, open or closed, safe or unsafe; the phosphorous acid synth or by the use of HI alone or with a little red ...

 · On my unit I must open the ash pan door to gain access to shake the grates. While shaking, I see a plume of fly ash come up out of the coal bed and move toward for the flue pipe. I'm sure its just settling in my horizontal/diagonal sections of pipe. Hmmm.. What can I do to slow this down.

Draw air through the Buchner funnel until liquid evaporates. Air dry overnight or dry in oven at 80 0C. (In oven drying phosgene is liberated and adequate ventilation must be provided). Transfer residue to 1 litre Wildman trap consisting of 1 or 2 litre Erlenmeyer flask into which is inserted close fitting rubber stopper supported on stiff
