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 keep good contact with the bottom of the tip itself.

• All cartridges have exactly the same length.

• Perfect needles without splatter and noise!

• The needles are made in 304 surgical stainless steel in our factory which has experience in needle manufacturing for over 100 years!

The soldering is 100% lead-free and gluing is done with ROHS-approved resin, unlike many "China needles" that figure on the market.

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

Diameters of 0.30, 0.35 and 0.40mm

The range is constantly changing to adapt to demand!

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

Sterilization protocol is provided on request. Certificates can be downloaded here .
