TOPS powder

Oxidation reaction
Usage:It can be applied to the enzymatic photometric determination of hydroge n peroxide as a water-soluble reagent, widely used in diagnostic tests and biochemical tests
Product Advantages:The product has good crystal form, high purity, high colour sensitivity, good water solubility and stable process, which can ensure the appearance of pure white crystal powder.

The following focuses on giving you an analysis of its advantages in various aspects, so that you can also judge accurately when choosing at a later stage.

I. Absorbance wavelength
The absorbance wavelength of TOPS oxidised products can reach 550NM, which is already far more than other reagents. TOPS is very suitable for biochemical research where highly accurate values are required. Due to the long absorbance wavelength, it is possible to better identify and judge the content of substances in the determination of some substances, which makes it easier to obtain accurate results without affecting the composition of the sample to be measured.

II. Wide range of solution pH
The advantage of the wide pH range of TOPS solutions is that if used in biochemical studies or enzyme photometric assays, the enzyme reaction is not affected to a greater extent. Because enzymes are more sensitive to environmental pH requirements in catalytic reactions, TOPS solutions have a pH range of 5.5-9.5, which is a suitable pH range for enzymes to survive and not easily change.

III.High molar absorbance
TOPS has a high molar absorbance of 3.74×10, which makes it more responsive during the detection process, but care needs to be taken that the detection time is not too long to ensure a rapid response without interruption in timely detection.

IV. High water solubility and purity
As TOPS is more sensitive to surrounding light and humidity, it has the advantage of high water solubility, while the purity is usually based on the manufacturer, such as the TOPS produced by Tesheng is up to 99% pure, suitable for most biochemical experimental projects, and process stability, we can also focus on the purity advantage when choosing. Also note that because of the good water solubility, TOPS needs to be placed in a light-proof and airtight container and kept at a temperature of 0-5 degrees.
