MICRONJET™ 30 needles are intended for use by licensed healthcare professionals, such as physicians, dermatologists, and trained aesthetic practitioners, within their scope of practice. The device is a disposable, single-use system. Use a new unit for every patient and never reuse or re-sterilize it.

The microneedle length sets the penetration depth and is not adjustable, so technique focuses on a consistent insertion angle and smooth injection rather than depth control. The fixed microneedle length limits how far the microneedles can extend into the skin, supporting shallow, consistent intradermal placement.

When buying online, professionals should confirm local regulatory requirements and any institutional purchasing or protocol rules before use. Standard aseptic technique applies, as does a thorough patient assessment. Only inject substances that are approved or appropriate for intradermal administration, because the device clearance is tied to that route. Product choice, dose, and treatment plan remain the practitioner’s clinical decision.

Moreover, the manufacturer describes the device as practically painless, and a comparative study in healthy adults found significantly lower pain scores with the microneedle than with conventional needles. Individual experience still varies with site, volume, and formulation.

The MICRONJET™ needle was developed for intradermal delivery and has been studied across several uses. In vaccination, a seven-year review of clinical experience summarised its use for delivering liquid vaccines. In diagnostics, a study of tuberculin skin testing found the device effective and safe, with lower pain than conventional injection.

In anesthesia, a randomized placebo-controlled trial used it to inject 100 µL of 2% lidocaine before peripheral intravenous cannulation, and pain scores fell about 11-fold compared with cannulation without pretreatment.

In aesthetic medicine, MICRONJET™ treatment involves delivering skin boosters and other products intended for intradermal administration. NanoPass positions the 600 µm version for shallow, consistent delivery in thin skin, fine wrinkles, and other sensitive locations. This positioning is relevant to questions about MICRONJET™ under-eye use, although suitability depends on the treatment area, product labeling, anatomy, and clinical judgment.

The MICRONJET™ range also includes variants with different needle lengths. MICRONJET™ 600, for example, has 0.6 mm microneedles. Specifications can differ between variants, so confirm the needle length on the product label and in the manufacturer’s instructions before ordering.

MICRONJET™ 30 Needles at a Glance

The MICRONJET™ 30 Device from NanoPass

NanoPass Technologies Ltd. produces the MICRONJET™ needle from silicon crystal using MEMS technology, the same class of fabrication used in semiconductor manufacturing. The result is a device that behaves differently from a hypodermic needle. Each unit is a female luer connector carrying a chip of hollow microneedles, and it fits any standard luer slip or luer lock syringe.

In the 600 µm configuration, the chip carries three pyramid-shaped microneedles, each 0.6 mm long. The device connects to a compatible standard syringe, allowing it to fit into familiar syringe-based workflows.

The MICRONJET™ platform is 510(k) cleared by the US FDA and CE marked. It also holds regulatory approvals in several other markets, and it is approved for delivering substances that are themselves approved for the intradermal route. NanoPass has supported the platform with clinical research in vaccines, anesthesia, and aesthetics.

Med Supply Solutions supplies this 30-pack to licensed medical professionals. Practices looking to buy MICRONJET™ 30 needles wholesale can contact the Med Supply Solutions team about current professional purchasing options and can also buy needles wholesale across the wider needles and cannulas range.

MEMS Silicon Technology Behind the MICRONJET™ Design

For clinical use, the key feature of the MEMS design is that microneedle dimensions are established during manufacturing rather than determined by freehand insertion. The silicon construction supports repeatable geometry and a fixed needle length from device to device.

Several design features follow from the technology:

• Fixed penetration depth: Microneedle length defines how deep the substance is delivered.
• Natural insertion angle: The MICRONJET™ 600 was developed to make the original model easier to use. Insert it at about 45 degrees, with no repositioning once in the skin.
• Visible confirmation: A successful intradermal injection produces a small bleb or wheal, the recognized hallmark of an acceptable intradermal injection.
• Syringe compatibility: The luer connection works with standard syringes.
• Resistance to blunting: The manufacturer describes the silicon-crystal pyramids as built to hold their sharpness.

These characteristics support the low-leakage and high-success profile the manufacturer reports.

The following is a general device workflow for professional settings and does not replace the current manufacturer instructions for use.

1. Check the device: Confirm that you have the correct MICRONJET™ format and that the package is intact before use.
2. Attach the device: Connect MICRONJET™ securely to a compatible standard syringe.
3. Prepare the treatment site: Follow your institution’s aseptic preparation protocol and label the product being injected.
4. Position the device: Insert the MICRONJET™ 600 at approximately 45 degrees.
5. Administer intradermally: Inject according to the applicable protocol. A visible bleb or wheal is the recognized indicator of intradermal placement.
6. After use: Treat the device as single-use and dispose of it according to applicable sharps and institutional requirements.

Store unopened devices according to the current product labeling and manufacturer instructions. After you purchase MICRONJET™ 30 needles online, confirm the product format and packaging before adding the devices to clinic stock.
