Reagent needle production cost, its inner hole polishing cost accounts for about half, cheap reagent needle is mainly no inner hole polishing, because the reagent is not acid or alkali, of course, the PH value will be different, the general inner hole is not polished reagent needle its inner hole hanging drop, the outer wall hanging drop, use a month, the inner hole began to rust, three months later the inner hole hanging drop is more serious, and then the inner hole reagent dry crystallization and plugging. If you clean more often, it will be better.
TP316L reagent needle best improve the corrosion resistance process: Internal and external polishing mirror + stainless steel special anhydrous passivation + internal and external surface for nano coating, the combination of three groups of processes, according to ASTM B117 standard for neutral salt spray test, can resist 2000 hours of continuous attack, the surface has no obvious reaction, some customers in the pH range of PH1.4 to PH13.2 reagent, used for 7 months, the surface has no reaction. There is no problem in the first half of the theory, and there is no problem as long as there is no man-made destruction.
In order to improve the corrosion resistance of the reagent needle, the internal and external holes are first polished mirror, and then passivated. If plastic cannot be used in the design of the assembly fixed base, it is best to use the same material as the reagent needle, or use a more active material than the needle material to form the cathode compensation principle, so that the corrosion resistance of the reagent needle is maintained to the optimal state. Theoretically, the pH of the reagent is not very limited. Seven years is no problem.

Interventional puncture needles and reagent puncture needles are used in different ways, one is used to insert the body to suck up liquid or administer medicine, and the other is used to absorb the reagent after inserting the silicone cap.
For reagent puncture needle, at present there are four kinds of needle structures on the market: conical with measuring holes, round head cone with side holes, cone and side holes on the bevel, double cut bevel with side holes.
There are 17 processes in the production of piercing needles, each step strengthens the detection details, makes wear-resistant sulfur water coating, improves the corrosion resistance, removes stress, polishing the inner hole of the needle to Ra0.1um, ultrasonic cleaning, polishing the surface of the needle to Ra0.07um, protected by silicone tube, and finally, acrylic transparent tube to protect its linearity from packaging pressure bending.
Our can make puncture needle, coaxial needle, guidance needle, positioning needle, drainage needle, biopsy needle, cutaneous kidney puncture needle, spinal puncture needle, abdominal puncture needle, sternal puncture needle, amniotic fluid puncture needle, follicle puncture needle, thyroid puncture needle, radiochemotherapy puncture needle, pulmonary tubercle puncture needle, sampling puncture needle, orthopedic puncture, and other various medical puncture needles.

Single-use Technology (SUT) – filling needle for biopharma.
Due to the characteristics of biological products, it is more difficult to control contamination and cross-contamination, and the risk is increased. From 1978 to the present, Single-use Technology (referred to as SUT) after more than 40 years of development, has covered the entire biopharmaceutical process of various operating units, from upstream biological treatment to final filling, single-use technology has become one of the most widely accepted technologies in recent years.

In aseptic filling system, disposable filling needle is an important part, the use of disposable filling needle can greatly improve the flexibility of production, further reduce production costs, in the face of the rapid development of the pharmaceutical industry and drug production process complex and unique characteristics.

Our filling needle features:
◎ It is composed of 316L and peek material, and the material of the direct contact part of the product is 316L.
◎ Meets the requirements of the United States Pharmacopeia for testing of insoluble particles and endotoxins
◎ It can be sterilized by wet heat or gamma ray irradiation and can be used at any time
◎ Increase production efficiency, reduce turnover and cleaning time
◎ Low or high speed filling possible
◎ Needle surface roughness ≤0.10μm, accurate volume filling
◎ Can be easily linked to the filling line or system
◎ Wide applications: disposable filling needles can be customized on existing filling machines
◎ Each filling needle comes with its own ID and batch number for easy identification of fully traceable production records
◎ The product is accompanied by test certificates and confirmation that the product meets the quality standards, including material quality inspection test certificates and COA report tests.

For ultra-precision pipette needle made of stainless steel capillary tube, of we can polish the surface of the inner hole to Ra0.02um. If you need, we can polish to 15nm=Ra0.0015um, super mirror inner surface.
