Assay preparation. Transfer not less than 20 Capsules to a blender jar or other container, and add about 150 mL of methylene chloride, and cool in a solid carbon dioxide acetone mixture until the contents have solidified. If necessary, transfer the mixture of capsules and methylene chloride to a blender jar, and blend with high-speed blender until all the solids are reduced to fine particles. Transfer the mixture to a 500-mL volumetric flask, add n-heptane to volume, mix, and allow solids to settle. Transfer an accurately measured volume of this solution, equivalent to 250 mg of valproic acid, to a 100 mL volumetric flask, dilute with w-heptane to volume, and mix. Transfer 5.0 mL to a container equipped with a closure. Add 2.0 mL of the internal standard solution, close the container, and mix. 

This may find application in several areas. The first example is the homogenization of animal tissues in a high-speed blender, which enables a homogeneous sample to be obtained for subsequent analysis. This is used, for example, in the analysis of arsenic or copper in liver (Ross, 1990). A second area is the extraction of volatile fatty acids from silage. Typically, 10 g fresh silage is homogenized for between 1 and 10 min with 100 ml water in a blender before filtration (Lessard et ai, 1961). The last area is the dry... 

Treatment of pre-ground fillers is also common, and is the method most often used in laboratory studies. This is carried out in a high speed blender such as a Henschel, where the intensive mixing can quickly raise the temperature to that needed for efficient coating. As with the previous process, sufficient time must be allowed for the reaction to go to completion and the amount of coating added must be carefully controlled. 

Let us see how thixotropic behavior relates to the phenomena of coagulation. The data shown in Figure 4.14a were obtained for a 7% slurry of carbon black in water. Curve 1 shows the results obtained immediately after the dispersion was prepared in a high-speed blender. After additional mild agitation, the results shown in curve 2 are obtained these are independent of further agitation. With shorter periods of mild agitation, a family of curves lying between 1 and 2 would be obtained. 

Dehydration experiments were performed with emulsions containing 201 water. The emulsions were formed by mixing crude and formation water for two minutes at the anticipated wellhead temperature of 66° C in a high speed blender. The demulsifier was added and dispersed in the emulsion by an additional 10 second mixing prior to transfer Into dehydration bottles which were heated In a water bath set at the desired temperature. 

Sample Preparation Transfer about 1 g of sample, previously reduced to a fine powder in a high-speed blender and accurately weighed, into a 10-mL volumetric flask, dilute to volume with chloroform, and shake for 5 min to extract the tert-butyl-p-benzoquinone. Filter through a Millipore filter (UHWP01300), or equivalent, before use. 

Cheese. Remove surface layer not usually consumed. Cut the sample into strips, pass several times through a food chopper and mix. Blend cream cheese and similar products in a high-speed blender for ca. 2—5 min until homogeneous. Alternatively mix well by intensive kneading. Store all samples in air-tight containers. 

For semi-solid and emulsified dressings, transfer a sample to a larger vessel, mix for ca. 2 min. until homogeneous and without delay, remove a portion for analysis. Blend separable dressings with 0.20 g of egg albumen powder as emulsifier per 100 g of sample in a high-speed blender. Mix thoroughly immediately prior to removing an aliquot for analysis. Correct analytical results for added emulsifier (include appropriate quantity of emulsifier in the blank determination). 

High-speed blender The disruption of droplets in a blender occurs mainly due to the existence of a turbulent flow situation. The energy input per unit volume is unevenly distributed in the apparatus. This results in a broad droplet size distribution. 

Each kidney was cut into pieces and homogenized in a high-speed blender. This step reduced the size of the tissue pieces and homogenized the resulting laboratory sample. 

A sample (5g) was blended three times with 20, 20, and 10 mL of 0.1 M Na2EDTA-McIlvaine buffer (pH 4.0) using a high-speed blender and centrifuged each time. The supernatants were combined, centrifuged again, and filtered. 

The initial step in purifying subcellular structures is to rupture the plasma membrane and the cell wall, if present. First, the cells are suspended in a solution of appropriate pH and salt content, usually isotonic sucrose (0.25 M) or a combination of salts similar in composition to those in the cell s interior. Many cells can then be broken by stirring the cell suspension in a high-speed blender or by exposing it to ultrahigh-frequency sound (sonication). Plasma membranes can also be sheared by special pressurized tissue homogenlz-... 

A typical extraction scheme for marine invertebrates (frozen, dried, or lyophilized) Invertebrates are cut into small pieces and macerated in a high-speed blender with solvent (see Note 4). The resulting extracts are filtered either through Whatman no. 1 filter paper (gravity or vacuum), or a bed of Celite 521 packed in a Bilchner funnel (see Note 5). AAct filtration, the tissue residue (marc) is returned to the blender and extracted with a second portion of solvent. This process is continued until no further color is extracted. In cases where the extracts are colorless, the successive extracts can be concentrated separately and the mass of residue after concentration determined. Extraction can be considered complete when little or no additional residue is obtained after concentration. When following bioassay-guided purification, successive extracts can be concentrated and assayed separately. Extraction is considered complete when no ftirther activity is detectaf in the extracts. In our lab, sanqiles are extracted three to six times to ensure complete extraction.
