TSK STERiJECT Advanced Needle (HPC)

Larger inner diameter with TSKiD™ Technology
STERiJECT HPC needles are designed with TSKiD™ Max barrels, which utilize advanced thin wall needle technology to improve injection performance. Unlike standard barrels, TSKiD™ needle barrels feature enlarged inner diameters that allow for more efficient flow and smoother delivery of products. TSK differentiates its technology into three categories—Standard, Large, and Max—each offering progressively greater increases in diameter. For example, a 30G needle with TSKiD™ Max thin wall technology has an inner diameter up to 65% larger than the ISO standard. This ensures less resistance, reduced injection force, and more precise product placement, particularly valuable when working with high-viscosity fillers and biologics.

Advanced hub geometry
High-viscosity products often create challenges during injection due to their thicker consistency. The thin wall needledesign of the HPC system addresses this by pairing TSKiD™ Max barrels with an advanced hub geometry. The hub features a wider internal structure that supports improved flow rates and reduces pressure build-up. In addition, the HPC hub is shorter in length compared to the PRC hub, providing a more compact and efficient system. This combination makes it easier for practitioners to deliver viscous products accurately and with greater control.

External 360 hub threading
To further enhance performance, the HPC or “advanced hub” incorporates external 360-degree hub threading. This engineering ensures a tighter and more secure luer lock connection between syringe and needle. By minimizing the risk of hub “pop-off” during high-pressure injections, the system guarantees greater safety and reliability. When paired with the thin wall needle design, this threading innovation allows practitioners to perform treatments with maximum confidence, knowing the connection is stable and secure throughout the procedure.

Hard polymer hub
Durability and stability are key considerations in needle performance, and the HPC system addresses this with hubs made from an extremely strong hard polymer. This material prevents flexing or deformation when exposed to high pressures, which in turn prevents leakage and needle pop-off. The rigidity of the hard polymer hub ensures consistent, safe, and predictable results, even in demanding clinical applications. Combined with thin wall needle technology and advanced hub geometry, the HPC needle system delivers a superior balance of strength, precision, and efficiency.

Why Choose a Thin Wall Needle?
Choosing a thin wall needle like the HPC system offers multiple advantages for both practitioners and patients. The enlarged inner diameter allows for smoother injection of high-viscosity products, reducing injection force and operator fatigue. Advanced hub design and external threading enhance safety by preventing leakage and accidental hub detachment, while the hard polymer construction ensures long-term reliability. For medical professionals, thin wall needles improve efficiency, precision, and overall treatment outcomes, making them the preferred choice for modern aesthetic and clinical procedures.
