Tris, or tris(hydroxymethyl)aminomethane, has been widely used as a pH buffer in biological media for about 35 years. The near-ideal properties of this biological buffer are the reason for its popularity. Tris does not absorb water, is easily soluble in water, and has high purity. It does not precipitate calcium salts, is stable in solution for several months at room temperature, and does not seem to inhibit many enzyme systems. However, due to the chemical and physical properties of Tris buffer, improper use may lead to erroneous pH measurement of the electrode system.
The influence of pH in TRIS buffer on electrode
Biochemists use TRIS buffers to control the pH within the physiological range (approximately 7 to 8 pH), because phosphate can cause adverse reactions with biological substances in the test sample. However, when pH measurements are to be made on these solutions, another type of "adverse side reaction" must be recognized, involving the pH electrode system.
The influence of chemical and physical properties of Tris buffer on pH
Tris, which is commonly used for physiological measurement (pH 7 to 7.5), does not have a large buffer capacity. Therefore, caution should be exercised when using tris buffer to control sample pH. The rather large temperature coefficient of tris (-0.028pH/ C) is also worth considering. For example, if the meter is calibrated with tris buffer and the tris temperature is 20 C, using a pH value of 25 C will cause errors. Therefore, temperature pH dependence must be used when using tris for standardization. When using tris to control the pH of the sample, the degree of control will depend on the sample temperature. If the sample temperature changes by 2 C, the pH control changes by about 0.06 pH units. The required pH control will determine the maximum allowable temperature fluctuations.
Advantages of Tris buffer
Because the Tris base is highly alkaline, this buffer system can be used to prepare buffers with a wide range of pH values from acidic to alkaline;
It has little interference to the biochemical process, and does not precipitate with calcium, magnesium ions and heavy metal ions.
Disadvantages of Tris buffer
The pH value of the buffer is greatly affected by the concentration of the solution. The buffer is diluted ten times, and the pH change is greater than 0.1; the Tris buffer should be prepared from high-purity tris and HCl using distilled or deionized water without CO2.
The temperature effect is large, and the temperature change has a great influence on the pH value of the buffer, so it must be prepared at the use temperature, and the Tris-HCl buffer prepared at room temperature cannot be used at 0 C to 4 C;
It is easy to absorb CO2 in the air, so the prepared buffer should be tightly sealed;
This buffer has a certain interference effect on some pH electrodes, so use an electrode compatible with Tris solution.

Since SIZEOMNI 40S is cationic can be used in combination with weakly cationic auxiliaries. For adding SIZEOMNI 40S, the pH of solution should be 4.
For enhance the SIZEOMNI 40S performance, cationic fixing agent should be required.
Application of SIZEOMNI 40S in the size press changes the wet ability of the paper and reduces its water absorption.
The presence of aluminium ions in the base paper is not necessary for obtaining optimum results. Since SIZEOMNI 40S is cationic, it cannot be applied in the size press with fluorescent whiteners and normal dyes or basic dyes. Only cationic dyes can be added in the solution.
The normal drying temperatures on the paper machine are sufficient to develop full sizing. No additional curing period is required.
SIZEOMNI 40S has good stability in the presence of large quantities of electrolytes.

SIZEOMNI 40S can be added batch-wise to the starch solution storage tank as well as continuously in the operating tank or the feeding pipe to the size press.
SIZEOMNI 40S is low foaming, so defoamers are normally not required.

$1.90
MOQ: 18000  Kilograms
Sample Available
Supplier From Rajkot, Gujarat, India
 
With our product name BONDOMNI 420 G, We produce SAE Anionic Surface Sizing Agent. Since BONDOMNI 420 G is anionic can be used in combination with weakly cationic auxiliaries.
Application of BONDOMNI 420 G in the size press changes the wet ability of the Paper and reduces its water absorption. The presence of aluminium ions in the base Paper is not necessary for obtaining optimum results.
Since BONDOMNI 420 G is anionic, it can be applied in the size press with fluorescent whiteners, direct dyes or basic dyes.
The normal drying temperatures on the Paper machine are sufficient to develop full sizing. No additional curing period is required. It has good stability in the presence of large quantities of electrolytes.
