Ratio Professional Cartridges

Ratio Professional Cartridges are the original as an evolution of our traditional needles with the same needles as in Ratio Fat Mags and Ratio Soft Grip Tip.

• A special sealing membrane technology that keeps the risk of contamination at bay.
• The needles are slightly bent to always maintain good contact with the bottom of the tip itself.
• All cartridges have exactly the same length.
• Perfect needles without splashing or noise!
• The needles are made of 304 surgical stainless steel in our factory, which has over 100 years of needle manufacturing experience!

The soldering is 100% lead-free and the glues are made with ROHS-approved resin, unlike many "China needles" on the market.

The needles are available in the most common configurations on the market.

Diameters of 0.30, 0.35 and 0.40mm

Our needles are inspected more than 30 times throughout production before the final Ethylene Oxide sterilization process. This makes Ratio Professional Cartridges one of the safest cartridges on the market!

Sterilization protocols are available upon request. Certificates can be downloaded here .
