Sample Processor JPY300

The equipment is used for the pretreatment of glass fiber and polyester fiber in the production of Immunoassayphy rapid tests. It is consists of three parts: feeding platform, reagent tank and upper and lower pressure roller. Firstly, the sample pad is fed into the reagent tank through the feeding platform and is absorbed in the reagent slot. The processed sample pad is driven by a stepping motor, and then the excess reagent is extruded out after through the upper and the lower pressing rollers. It has the advantages of simple structure, convenient operation and uniform treatment, which greatly improves the processing efficiency of the sample pad..

Superuniform spherical gold nanoparticles

Introduction

Gold nanoparticles, with their excellent conductivity, stability, biocompatibility, and surface optical properties, have irreplaceable roles in optics, catalysis, electronics, immunodiagnosis, biosensors, biological imaging, and drug delivery. At present, sodium citrate reduction method is a classic method for preparing gold nanoparticles, but the prepared gold nanoparticles have irregular shapes, and their uniformity and stability are not ideal. Therefore, the preparation of gold nanoparticles with different particle sizes that have regular shapes, uniform particle sizes, good dispersibility, and stable properties is an urgent problem to be solved in current production. We first used chemical reduction method to prepare 5-15 nm small diameter super uniform spherical gold nanoparticles. Using small diameter spherical gold nanoparticles as seeds, we used seed growth method to prepare 20-200 nm super uniform spherical gold nanoparticles. The spherical gold nanoparticles prepared by this method have uniform particle sizes, regular shapes, and uniform dispersion; Depending on the particle size, it presents different colors in aqueous solution, such as orange, red, magenta, and brick red.

Preparation of gold nanoparticles with different particle diameters

Methods:
Prepare 5 to 15 nm super uniform spherical gold nanoparticles with chemical reduction method. Using 15 nm gold nanoparticles as seeds, prepare 20 to 200 nm super uniform spherical gold nanoparticles with seed growth method.Then characterize the prepared gold nanoparticles.

Conclusion

Plastic Backing Card
  • Uniform particle diameters, regular shape, small coefficient of variation
  • Stable quality, stored at 4 ℃ for 2 years
  • The production capacity is sufficient, with a batch capacity of up to 2000L, ensuring a stable batch capacity of up to one million liters per year.
  • Customizable according to user needs
  • The colloidal gold solution can be ordered with particles diameter from 10 to 80 nm, with minimum order of 20 ml.

Plastic Backing Card
The plastic backing card plays the role of bearing and binding the material in the production of the lateral flow rapid test strip. Kinbio may provide various models of rolling materials or sheets according to the customer requirements (the size and cutting line position may be customized), and can also offer the backing card for fluorescence using and backing card with good weather ability.
Plastic Protective Film or PE Marks Film
The role of plastic protective film is to prevent pollution, while label on the PE marks film can play a guiding role. It is suitable for the colloidal gold test strip chromatography membrane ends angle film arrow label and absorbent paper covering the label. Long term preservation is not easy to glue off. According to the requirements of customers, we can produce a variety of sizes, patterns and colors of the roll or strip protective film.
Polyester Fiber
It is made of Polyester film formed by specific process. It has good hydrophilicity after special treatment. The fibers are arrayed evenly and fine in the pattern. Fibrous membrane component is biological inert, there is no influencing on the normal reflection of bioactivator. So it is suitable for colloidal gold conjugated pad or sample pad.
Glass Fiber
Glass fiber is mainly used as the conjugated pad or the sample pad in the production of immunochromatography rapid tests. After many years of selecting, Kinbio chooses a variety of glass fiber membranes suitable for Immunoassayphy. These fibers have the characteristics of smooth surface, uniform fiber arrayed, uniform thickness and so on. Kinbio can provide customers with a variety of specifications of the roll type, sheet materials for the customers.
Special Absorbent Paper
White absorbent paper is made of pure plant fiber via the special process without chemical additive and with good water absorption ability. Different models of absorbent paper have different absorbing speed and quantity, and may be used in different rapid tests.
Nitrocellulose Membrane
Nitrocellulose membrane (NC for short) is based on organic chemical nitrocellulose particles, added with surfactants, high molecular polymers, salt ions, molding agents, etc., dissolved to form a mixed homogenate, and the prepared homogenate is pressed through a roller to form a film. This kind of film is called nitrocellulose membrane. The membrane is one of the most important consumables in biological experiments. It is widely used to make immunochromatographic diagnostic strips. It is not only the carrier of C / T line, but also the place of immune reaction.
