Written by the company

TSK Laboratory International strives to make injections perfect. We have a long successful history in the development and manufacturing of specialty needles and medical devices, which resulted in multiple patents for both materials and needle designs. The premium quality of our products makes TSK Laboratory International the preferred partner for many leading pharmaceutical and medical device companies worldwide. At TSK Laboratory International, we put great emphasis on developing new technologies and product innovations. We aim to deliver new solutions to the aesthetic, interventional radiology, ophthalmology and dental market, that improve the clinical outcome while simultaneously improving patient safety and comfort. Two examples of those innovations are the STERiJECT ULTRA Thin Wall and the STERiJECT LOW DEAD SPACE hub design. Due to the high viscosity of dermal fillers, and small particles contained within the dermal filler, injecting the filler can become quite difficult. Regular needles can easily dislodge from the syringe due to the applied pressure, or get occluded. Needle leakage and needle pop-off further complicate the injection of dermal fillers with regular needles. In order to overcome these issues and simplify the injection process, TSK Laboratory International developed STERiJECT ULTRA Thin Wall needles. The increased inner diameter of the needles ensures that up to 35% less extrusion force is required, allowing for a smoother and more controlled injection. Combining the ULTRA Thin Wall Needles with the STERiJECT PRC and STERiJECT HPC needle hubs, TSK was able to further improve on the injection of dermal fillers. The hard polymer of these needle hubs, optionally combined with external threading (HPC hub), prevents product leakage and needle pop-off. Using blunt tip cannulas instead of needles for injecting dermal fillers, practitioners significantly reduce the risk of injecting into a blood vessel. The blunt tip makes for a safer injection, but also comes with a downside: the introduction into the skin required quite a lot of force, frustrating aesthetical professionals and providing discomfort for their patients. In order to overcome the downsides of using cannulas instead of needles, TSK developed the STERiGLIDE cannula. The dome shaped tip and a proprietary surface treatment offer an easier cannula introduction and provide up to 50% better gliding. Less introduction force is needed, reducing the risk of bruising and patient discomfort. The STERiGLIDE cannula also provides the nearest to tip filler delivery, ensuring a more accurate filler placement and reducing the product loss in the tip ending. This, combined with a clear side-port marking on the hard polymer hub, allows practitioners to implement a more accurate filler placement and offers the best possible handling. With BoNT injections, doctors and practitioners are working with a high value substance. Ideally, a minimal product loss ensues when injecting these substances. Traditional needle hubs have a large dead space, often causing significant product loss. To counter this issue, TSK developed a shorter needle hub, with a minimized dead space: the Low Dead Space hub. Further improving on the experience of applying BoNT injections, TSK Laboratory International developed a new STERiJECT needle innovation: THE INViSIBLE NEEDLE. THE INViSIBLE NEEDLE is the first needle of its kind, and it is the thinnest needle available to date. Being 14% thinner than a 33G needle, THE INViSIBLE NEEDLE provides a near painless injection, while also strongly reducing the risk of bruising. THE INViSIBLE NEEDLE provides the best overall patient experience and has set a new standard for injecting high value substances within a variety of markets.
