Lutronic Infini RF tips are replaceable microneedle electrode cartridges used with the appropriate Infini system and handpiece. When ordering replacement consumables, the complete product reference matters more than a general description such as “49-pin RF cartridge.”

Clinics need to distinguish needle configuration, insulation, manufacturer identity and equipment compatibility before purchasing.

This guide explains the documented Infini microneedle design and the information buyers should verify. It is intended for professional product identification and procurement. Clinical operation must follow the current manufacturer instructions for the exact equipment.

What Are Infini RF Tips?

An Infini tip is the cartridge component containing the microneedle electrodes used with the system’s handpiece.

Lutronic’s published brochure describes Infini as a bipolar radiofrequency system that delivers energy through insulated microneedles. The cartridge is separate from the main device and handpiece. cdn.komachine.com

Suppliers may use several descriptions:

• Lutronic Infini tips.
• Infini RF cartridges.
• Infini replacement tips.
• Infini 49-pin cartridges.
• Infini MFR needle tips.
• Infini insulated microneedle cartridges.
• Lutronic Infini consumables.

These phrases help identify the product category. They do not independently establish the exact model or supported equipment.

Infini 49-Pin Cartridges and the 7 × 7 Array

The referenced Lutronic brochure describes a seven-by-seven array of 49 insulated microneedles. cdn.komachine.com

The number 49 identifies the needle count. The description 7 × 7 identifies the rows and columns in that array.

It does not mean the cartridge measures seven millimeters across. Physical dimensions, needle spacing and operating specifications require separate documentation.

What Does “Insulated” Mean?

In an insulated microneedle design, an insulating coating covers part of the needle shaft, leaving a designated conductive section exposed.

This construction differs from a non-insulated design. The exact exposed section, coating and operating characteristics should be established from documentation for the specific cartridge.

The term “insulated” does not guarantee a particular clinical result or eliminate procedural risks. Equipment condition, operating parameters, patient assessment and clinician training remain important.

When purchasing Infini insulated tips, request a product description that explicitly identifies the needle design. Do not infer insulation from needle count, color or appearance.

Infini MFR Tips: Use the Complete Reference

MFR commonly refers to microneedle fractional radiofrequency in product descriptions. For procurement, it is useful terminology but should not replace the exact cartridge reference.

Public device-identification records include descriptions such as INFINI MFR TIP A-49 and INFINI MFR 49 TIP II. These records support the importance of checking the complete product identity rather than treating all Infini 49-pin listings as identical. gs1

A device record does not authenticate a seller’s goods or establish interchangeability between references.

Before ordering, ask which exact product will be shipped and what documentation supports its compatibility with your equipment.

Are All 49-Pin RF Tips Compatible With Infini?

No compatibility should be assumed from needle count alone.

Different RF microneedling systems may use 49-needle configurations while having different mechanical connections, electrode designs and operating requirements.

A similar-looking cartridge may not be suitable for an Infini handpiece. Even physical attachment does not independently establish correct electrical or mechanical operation.

Verify:

1. Exact console model.
2. Handpiece identification.
3. Cartridge reference.
4. Supported equipment combination.
5. Applicable manufacturer instructions.

Where uncertainty remains, obtain confirmation from the manufacturer or the service provider responsible for the equipment.

Infini and Lutronic Genius Tips

Infini and Genius are different product names within Lutronic’s portfolio. Shared branding does not establish cartridge interchangeability.

Do not purchase Genius tips as Infini replacements solely because a listing states “Lutronic 49 pin.”

A complete quotation should name the supported system and exact consumable. Product photographs, written descriptions and invoice references should agree.

Needle Count Is Different From Treatment Depth

A 49-pin cartridge description does not identify a recommended treatment depth.

The referenced Infini brochure describes a maximum needle depth of 3.5 mm for that system configuration. This is an equipment specification from the brochure, not a treatment recommendation or confirmation of every device version. cdn.komachine.com

Keep these specifications separate:

• Needle count.
• Needle arrangement.
• Insulation design.
• Supported operating depth.
• Cartridge identity.
• Clinical operating parameters.

Clinical settings must come from the current instructions and professional training.

Original and Compatible Infini Cartridges

Product origin and compatibility are different questions.

A cartridge described as “compatible with Infini” is not automatically manufactured by Lutronic. A seller advertising “original Infini tips” should provide evidence supporting that claim.

Ask:

• Who manufactured the cartridge?
• What supports its stated origin?
• Which equipment does it support?
• What documentation establishes compatibility?
• Is the seller independent or authorized?
• What support or warranty applies?

An independent seller may offer manufacturer-original goods, but that origin still requires verification.

Packaging photographs assist identification. They are not conclusive proof of authenticity.

Packaging, Expiry and Single Use

Follow the labeling and instructions applicable to the supplied cartridge.

Before use, confirm the exact model, batch information, expiry and protective packaging condition. A familiar outer carton does not establish that every individual package is intact.

For cartridges labeled single-use, do not clean them for reuse or share them between patients. Follow the applicable handling and disposal instructions.

Keep expired, damaged or unidentified items separate from usable inventory.

What If an Infini Tip Does Not Fit or Operate?

Stop and follow the equipment instructions.

Do not force the cartridge into place, modify the connection or bypass an error. A problem may involve the cartridge, handpiece connection or system condition.

For support, record:

• Cartridge reference.
• Lot or batch information.
• Device and handpiece identification.
• Exact error message.
• Circumstances in which the problem occurs.
• Relevant photographs or video.

Exclude patient-identifying information from supplier communications. Persistent problems should be assessed by a qualified service provider.

Frequently Asked Questions

Are Infini tips and cartridges the same category?

Suppliers commonly use both terms for the replaceable needle consumable. Confirm the exact reference.

Does 7 × 7 mean 49 needles?

Yes, for the documented seven-row, seven-column configuration.

Are Infini needles insulated?

The referenced Lutronic brochure describes an insulated 49-microneedle array. Verify the actual product offered.

Can another brand’s 49-pin cartridge replace an Infini tip?

Do not assume compatibility from needle count or appearance.

Are Infini and Genius cartridges interchangeable?

Shared manufacturer branding is insufficient. Verify the specific supported combination.

How many Infini tips come in a box?

Confirm the pack quantity on the quotation. Do not assume every seller supplies the same number.

Does an equipment connection prove authenticity?

No. Product origin requires separate verification.
