Description
Technical field
The utility model belongs to chemicals technical field, relates to the auxiliary reagent in biology, medical science and chemical test, specifically provides a kind of adjust ph borate buffer substrate tablet.
Background technology
Buffered soln is a kind of solution can resisted pH when adding a small amount of acid or alkali and change.PH buffered soln to maintaining biological normal ph, normal physiological context plays an important role.Most cell only can carry out activity within the scope of very narrow pH, and needs buffer system to resist the pH change occurred in metabolic process.
Buffered soln is auxiliary reagent conventional in biology, medical science and chemical experiment, and frequency of utilization is high, usually uses and once just needs oneself preparation once, and therefore prepare buffer salt solution and seem very numerous and diverse time-consuming, workload is large
Borate buffer solution (BBS) is one of biomedical the most frequently used buffer system, by chemical reagent such as precise boric acid, borates, be mixed by a certain percentage, and it is high to reagent requirement content, crystal water is accurate, structure does not change, especially at borax under different humidity, under degree different condition that there was dampness in the air, its crystal water is unfixed, so the buffered soln prepared with general reagent level borax, pH has very big error, so a kind of method finding simple and quick preparation buffered soln is very important.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art part, a kind of adjust ph borate buffer substrate tablet is provided, adopt pressed disc technique, prepare auxiliary reagent experiment reaction environment soda acid situation being played to shock absorption, the plurality of advantages such as tablet has plug and play, is easy to storage and custody, preparation method is simple and quick.
The technical scheme that the utility model realizes object is as follows:
A kind of adjust ph borate buffer substrate tablet, described tablet is that cross section is rounded, square, rhombus, cruciate flower shape thin slice.
And the thickness of described thin slice is 1-10mm.
And the moiety of described thin slice is: major ingredient, auxiliary material, disintegrating agent, tackiness agent.
And described major ingredient is boric acid; Described auxiliary material is borax; Described disintegrating agent is cross-linked amylose, Microcrystalline Cellulose or polyvinylpolypyrrolidone etc., and described tackiness agent is cross-linked amylose, Microcrystalline Cellulose, polyvinylpyrrolidone, partly-hydrolysed polyvinyl alcohol, amylopectin.
And, there is bubble in described thin slice.
The beneficial effects of the utility model are as follows:
1, the application prepares a kind of pH damping fluid first and regulates borate buffering tablet, by precise boric acid, borate and auxiliary agent, after mixing, compressing tablet is made by a certain percentage, material composition is fixed, and the crystal water of boric acid is immutable, secures the ratio between the content of often kind of composition and composition, ensure that the stability of the value of pH during each use, the phenomenon that the pH that the environmental factors of effective eliminating causes is inaccurate, ensures carrying out smoothly of experiment, and the accuracy of result.
2, the borate buffering tablet that prepared by the application belongs to model of instant use once to turn it on, as long as in the solvent of fixed volume, drops into tablet, just can dissolve rapidly, the buffered soln of the pH value accurate stable needed for can obtaining, use and easy, reduce the duplication of labour, reduce labour intensity, increase work efficiency.
3, the borate buffering tablet that the application provides is easy to storage and custody, and be easy to carry transport, is convenient to pack, extends the storage life, reduces and produce and use cost.
4, the preparation that the borate that the application provides cushions tablet is simple and quick, and preparation process does not relate to high-temperature high-voltage reaction, can carry out suitability for industrialized production.
