26G Stainless Steel Back Cut Bevel Point Needle Tube For Medical Puncture , ISO9626 SUS304

26G Stainless Steel Back Cut Bevel Point Needle Tube For Medical Puncture , ISO9626 SUS304

Stainless steel back cut point needle tube combines the corrosion resistance of SUS304 stainless steel with a precision-engineered needle tip, which is widely applied for medical, industrial, and laboratory equipments. The back cut bevel enhances functionality by improving sharpness and reducing insertion resistance. Bevel angles and back cut depths of needle tubes may vary to optimize performance for different use, e.g., shallow angles are used for delicate tissues and steeper angles are used for tougher materials. We can provide custom-made blade surface angles according to clients' requests. Except for the back cut point needle tube, Our company can also design different needle points for different stainless steel needle tubes, such as lancet bevel point, back-eye point, huber point, pencil point, quincke point, flat bevel point, and so on.

Design Features:

• Needle Tube: A thin, hollow cylindrical structure optimized for fluid delivery (e.g., injections, sampling) or precise penetration.
• Bevel Point: A sloped, sharpened tip allowing smooth insertion into materials (e.g., skin, rubber septa, or industrial membranes). Reduces pain in medical use and minimizes damage to substrates.
• Back Cut: A secondary grind on the opposite side of the primary bevel. This enhances sharpness, reduces insertion force, and prevents coring (retention of material within the needle). The back cut may also create a multi-faceted edge for improved durability and performance.

Key Benefits:

• Reduced Clogging: The back cut design helps eject material cleanly during withdrawal.
• Enhanced Sharpness: Dual grinding (primary bevel + back cut) ensures a sharper, longer-lasting tip.
• Material Compatibility: SS304 resists oxidation and chemical reactions, ideal for sterile or corrosive environments.

The Structure Of Back-cut Point Needle Tubes:

Advantages Of SUS304 Stainless Steel Material:

• Properties: Austenitic (non-magnetic), excellent corrosion resistance, durability, and biocompatibility. Suitable for medical and industrial use due to its resistance to sterilization processes (e.g., autoclaving) and harsh chemicals.
• Advantages: Non-reactive, reusable, and maintains structural integrity under stress.

Applications:

• Medical: Hypodermic needles, biopsy tools, suturing, or catheters.
• Industrial: Precision fluid dispensing (e.g., adhesives, lubricants), sampling in chromatography, or piercing seals in packaging.
• Laboratory: Use with septa in vials for gas/liquid extraction without clogging.
