The hard polymer HPC or “advance hub” has a wide internal geometry for improved flow rates and an overall shorter length than traditional hubs. It also allows for a tighter luer lock connection because of the built-in exterior treading.
The PRC or “control hub” is made of extremely hard polymer preventing “flexing” of the hub when exposed to high pressures which ultimately prevents leakage and needle pop-off. It has a traditional hub geometry making it compatible with all syringes.
Independent studies have confirmed that the TSK needles outperform all competitors. Tests showed lower extrusion forces and smoother extrusion force profiles. thus allowing a better flow rate and reduced pop-off risk.
Due to the thin and ultra sharp needles TSK showed the lowest traumatic effect for the patient. This makes the TSK dermal filling needles the preferred needle for all major filler brands.
