What's the difference between borosilicate and datolite?
Borosilicate
Definition:
(n.) A double salt of boric and silicic acids, as in the natural minerals tourmaline, datolite, etc.
Example Sentences:
(1) Both series were prepared by incorporating a silanated barium borosilicate filler into a visible-light-activated polyphenylene polymethacrylate resin matrix.
(2) Results of these studies are presented in this article and are discussed in terms of the interactions between borosilicate glasses and aqueous solutions.
(3) The generator column is a borosilicate glass tube with 30 microns fused glass frit containing 0.75 ml AG1X8 anion exchange resin.
(4) Medium Eagle MEM with the addition of allogeneic serum and borosilicate glass were used.
(5) As has been observed in the past, fibrinogen adsorption peaked at intermediate plasma concentrations on both Pyrex and borosilicate glass (the so-called Vroman effect), but almost twice as much fibrinogen adsorbed to glass when TRIS was used to dilute the plasma instead of CPBSz.
(6) Blood lead, erythrocyte protoporphyrin, and hemoglobin levels were measured for family members of workers exposed to lead borosilicate dust in a capacitor and resistor plant in Colorado.
(7) It was observed that borosilicate glass prefilters have a high absorptive capacity for isolated rat-liver mitochondria and that this binding does not need any kind of chemical procedure.
(8) The elements are extracted with concentrated nitric acid in borosilicate glass tubes at 90 degrees C for 1 h, and determined by flame atomic absorption spectroscopy.
(9) Borosilicate glass (G) and commercial poly(methyl methacrylate) (PMM) surfaces were examined at pH 7, monovalent ionic strength 0.14 and 22 degrees C. Thrombin concentrations ranged from 6 X 10(-9) to 5.2 X 10(-8)M. Decreases in thrombin concentration in 10 ml vessles were determined by clotting time assay.
(10) PCV determinations were made on five patient blood samples using eight tubes of varying diameters, four made of soda-lime glass and four made of borosilicate glass.
(11) Gel portions containing protein stained with Ponceau S are excised and transferred to borosilicate glass digestion tubes containing 0.9 ml of 1 mM NaOH or 5 mM Na2HPO4.
(12) A 0.32 mm id X 30 m fused silica column and a 0.75 mm id X 30 m borosilicate glass column (both with OV-1 bonded phase) are investigated.
(13) There was no sorption to soda glass tubes, borosilicate glass volumetric flasks or soda glass microlitre syringes but minor sorption to polypropylene syringes, polypropylene pipette tips and rubber bottle stoppers after 240 min contact.
(14) The surface topography of USP Type I borosilicate glass containers was viewed after exposure to "sulfur," ammonium bifluoride, and sulfuric acid treatments.
(15) Gel filtration high performance liquid chromatography using a Borosil TSK 400 column shows that the tetrameric state of the native enzyme is not affected by the presence of the effectors.
(16) The uptake or adsorption of radioisotopically labeled oleic acid and cholic acid by plastic tubing of Tygon, Teflon, and polyethylene, and Pyrex, and borosilicate glass, and steel was measured.
(17) Extended-tip shunting was avoided by fabricating Na+ ion-selective microelectrodes from aluminosilicate rather than borosilicate glass.
(18) Borosilicate surface was rated at an intermediate level, but it did not provide good matrix for coating due to its poor reproducibility.
(19) In contrast, hydrolysis in borosilicate glass vials is useless, since nanomoles of sulfate added cannot be recovered adequately.
(20) This article discusses the results of studies that utilized Electron Spectroscopy for Chemical Analysis (ESCA), a surface analytical technique, in conjunction with Ar+ ion milling, a method of depth profiling, to examine some borosilicate glass containers.
Datolite
Definition:
(n.) A borosilicate of lime commonly occuring in glassy,, greenish crystals.
