Because the Prime Line High Speed handpieces have had such success, titanium-coated Straight and Contra Angle handpieces have also been added to the series, as well as Contra Angle Heads that feature Prime Line design and the latest technology. The Prime LS Line offers a 1:1 transmission and Contra Angle handpieces that have reductions of 2,7:1 and 7,4:1. You can get a variety of possible reductions when using them with KaVos Contra Angle Heads or MK-dents. The Prime LS line fits any ISO-standard/INTRAmatic® connections and is KaVo compatible, and the Glass Rod Light Conductor passes through lossless at 40,000 LUX.
