| macro-Kjeldahl method | A procedure for analyzing the content of nitrogenous compounds in urine, serum, or other specimens, usually to determine relatively large amounts of nitrogen (e.g., 20 to 100 mg); the specimen is treated with a digestion mixture (copper sulfate and sulfuric acid), heated thoroughly, and made alkaline with a solution of sodium hydroxide; ammonia is then distilled from the mixture, trapped in a boric acid-indicator solution, and titrated with standard hydrochloric or sulfuric acid.

| micro-Kjeldahl method | A modification of the macro-Kjeldahl method designed for the analysis of nitrogenous compounds in relatively small quantities, e.g., specimens in which the total content of nitrogen is in the range of 1 to a few mg. (05 Mar 2000) |
| Kjeldahl apparatus | <apparatus, chemistry> An apparatus for distilling ammonia arising from acid decomposition of an organic compound; used in nitrogen analysis. (05 Mar 2000) |

| Kjeldahl method | More specifically see: macro-Kjeldahl method, micro-Kjeldahl method. (05 Mar 2000) |
| vacuum flask | <apparatus> A glass vessel, often silvered, with two walls, the space between which is evacuated; used for maintaining materials at constant temperature or, more usually, at low temperature. Synonym: vacuum flask. (05 Mar 2000) |
| casting flask | A metal tube in which a refractory mold is made for casting metal dental restorations or appliances. Synonym: casting flask, casting ring. (05 Mar 2000) |
| refractory flask | A metal tube in which a refractory mold is made for casting metal dental restorations or appliances. Synonym: casting flask, casting ring. (05 Mar 2000) |
| volumetric flask | A flask calibrated to contain or to deliver a definite amount of liquid. (05 Mar 2000) |
| crown flask | A sectional metal boxlike case in which a sectional mold is made of plaster of Paris or artificial stone for the purpose of compressing and curing dentures or other resinous restorations. Synonym: crown flask. (05 Mar 2000) |
| denture flask | A sectional metal boxlike case in which a sectional mold is made of plaster of Paris or artificial stone for the purpose of compressing and curing dentures or other resinous restorations. Synonym: crown flask. (05 Mar 2000) |
| Dewar flask | <apparatus> A glass vessel, often silvered, with two walls, the space between which is evacuated; used for maintaining materials at constant temperature or, more usually, at low temperature. Synonym: vacuum flask. (05 Mar 2000) |
| injection flask | A denture flask designed so as to permit the forced flow of denture base material from a reservoir into the mold after the flask is closed and during curing. (05 Mar 2000) |
| erlenmeyer flask | <apparatus> A piece of chemistry laboratory equipment, a container often made of glass, which has a narrow cylindrical mouth and a cone-shaped main body that ends in a wide, flat bottom. It may also have a smaller straight tube-shaped opening from the side of the cylindrical part, where tubes can be attached. (09 Oct 1997) |
| erlenmeyer flask deformity | <radiology> Abnormal modeling of metaphysis, osteopetrosis, chronic anaemia (e.g., SSD), Gaucher disease, Niemann-Pick disease, fibrous dysplasia, Pyle disease (metaphyseal dysplasia) (12 Dec 1998) |
