Ophthalmic Microsurgical Needle

High-performance stainless steel needles designed for ultra-precision, low-volume liquid delivery are suitable for applications that require extremely high precision and airtightness.

Tip O.D: 120μm
Tip I.D: 35μm
Tip Length: 3mm
Total Length: 33mm
Shank O.D: 460μm

Material: stainless steel
Features: ultra-high precision, extremely small flow control, extremely low residual volume
Core advantages
Ultra-precision delivery - precise control of nanoliter (nL) to microliter (μL) liquids to reduce waste and errors.
Optimized airtightness - ensures leak-free liquid delivery, especially suitable for sensitive experiments or biomedical applications.
Minimally invasive - the slim needle design can reduce tissue damage and is suitable for scenarios such as in vivo injection and micromanipulation.
Strong durability - stainless steel is resistant to bending and chemical corrosion and can be sterilized repeatedly.

Typical applications
Life sciences: single cell injection, embryo manipulation, microsurgery assistance
Laboratory research: microfluidic chip sampling, micro-reagent distribution
Medical devices: ophthalmology/neurology precision drug delivery, subcutaneous micro-infusion
Industrial precision dispensing: electronic packaging, micro-droplet coating
