Needle, piercing, nozzle

In addition to improvement in dead volume at a needle tip of a needle nozzle and special structure of a pipe, quantitative dispensation and high accurate analysis are enabled by technologies such as inner surface poishing and surface treatment.

1) Joint part of a device and a pipe

If cutting marks or scratches exist on an end face, they cause liquid leakage. Therefore, needles made by FUTA-Q, Ltd. are finished considering sealing performance, resulting no leakage.

2) Assembling structure

Needles made by FUTA-Q, Ltd. can be assembled in different variations such as laser welding,epoxy adhesion,, brazing, and soldering.

③-1■ Inner diameter polishing technology (Applicable to difficult-to-cut materials such as SUS316L andpure titanium Class 2)

Before polishing.FUTA-Q.japan←【Before polishing】
Inner diameter of a small pipe sold on the market is not an exact circle. When using the pipe for analysis, liquid remains in roughness on inner surface of a pipe, and a residue is left even after cleaning. Therefore, accurate analysis results are not obtained.

After polishing.FUTA-Q.japan【After polishing】→
The inner diameter polishing performed by FUTA-Q, Ltd. improves circularity and smoothness on inner surfaceof a pipe. Thus, removing a residue by cleaning becomes easy. Moreover, as liquid is hardly left, the pipe can be used as the needle for quantitative analysis.。

3)-2■ Air pressure release technology (Air vent)

This is the method to adjust pressure to atmospheric pressure when aspirating a specimen from a sealed container such as an evacuated blood-collecting vessel, or when discharging it. FUTA-Q, Ltd. offers two kind of air pressure release technology.

1)Double needle structure
Outside of a main needle pipe, a pipe for air pressure release is fixed by welding or a similar way.
The products are available in all sizes.

2)Grooved needle structure

A groove is provided on the side of a needle pipe for air pressure release.
When impaling it, no resistance is made.

3)-4■ Improvement of draining and repellence 

Draining and repellency are improved by nozzle shaping (long taper) and various surface treatment. We propose coating such as PTFE, which has high insulation effect, and F2901, which is colorless, transparent and 1μm or lower in thick

4) Tip processing technology

4)-1■ Dead volume

A space inside the needle tip is considered as a dead volume that results in liquid residue.
This will cause contamination and deterioration in the analysis accuracy. FUTA-Q has its unique processing technology to manufacture needles without making a dead volume o the inner surface.
