High-Voltage Leak Detection Study

Container closure testing (CCIT) has many different method variations ranging from pharma packaging to medications by themselves. Companies implements these tests for the health and safety of the public. A study was recently conducted by Nadeen Bahnam, a researcher at Uppsala University. The aim was to explore High Voltage Leak Detection (HVLD) viability as a CCIT method concerning FDA requirements. Researcher Bahnam achieved this by comparing HVLD to other known CCIT processes. The purpose of CCIT is to make sure that no contaminants of any kind, such as microorganisms, find their way into sterile products and render them useless. The study outlines CCIT methods that fall under destructive and probabilistic or nondestructive and deterministic. Deterministic methods remove randomness and provide quantitative data points assuming conditions are kept constant. By contrast, probabilistic tests include a degree of randomness, requiring a large sample size to draw conclusions. Each method has advantages and disadvantages that determine its application. The method chosen must detect the minimum-sized leak allowed for a given product.

HVLD works by passing a current through a container, and if a leak is present, the returning voltage will be higher based on the size of the leakage. The method gives fast results and is flexible given the container is nonconductive and the packaging contains a conductive liquid. Researcher Bahnam chose Lenox Laser as the supplier of reliable leaks to evaluate HVLD because of our small-hole drilling capabilities. We were selected over other suppliers because of our ability to provide certification and produce holes of 5μm or less.

Lenox laser was privileged and honored to provide test packaging for this study. We are proud to help further research in such a vital field as CCIT.

Join Lenox Laser at 2021 PACK EXPO

The 2021 PACK EXPO will be one of the first major in-person healthcare product events since the COVID-19 lockdown last year. The expo will encompass many different companies and experts in the healthcare field discussing various packaging and processing methods. It is estimated that over 20,000 experts will be in attendance when the event takes place this September 27-29 at the Las Vegas Convention Center. PACK is expected to have an estimated 1,500 exhibitors showing off their products. Topics covered will include cost-effective digital printing solutions in pharmaceuticals, recyclable, and bio-based packaging. The expo will also have an exhibit that will take visitors through the evolution of processing and packaging in the pharmaceutical industry and more. The expo sponsors and hosts include the Reusable Packaging Association, the National Confectioners Association, and many more.

Lenox Laser will be in attendance at booth #6817, showcasing our Container Closure Integrity Testing (CCIT) methods and services, which we have continued to evolve in our excellent 40 years in business. We are privileged and very honored to be a part of the expo and cannot wait for you all to see what we have in store. Given the immense challenge 2020 presented, an event like this will prove significant. To all those attending and showcasing, we hope you enjoy the expo and send our best wishes. See you in September.

A Look into Our CCIT Capabilities

                As the pioneer in laser drilling, Lenox Laser takes pride in the various services that we provide to our customers. In light of the COVID-19 pandemic, the importance of Container Closure Integrity Testing (CCIT) has become abundantly clear. Confidence in pharmaceutical packaging is vital to prevent widespread damage caused by the failure of critical seals. Lenox Laser assists in this process by producing standards that calibrate leak-detection systems in order to assure the quality and safety of the packaging.

                By utilizing lasers, Lenox drills precise, microscopic imperfections in a wide variety of packaging. Our systems are capable of drilling metals and alloys, glass, plastics, and more. We can accommodate custom materials and requirements upon request. All orifices drilled for CCIT are calibrated to NIST secondary standards using our proprietary flow calibration processes, ensuring precise measurements. Recalibration services are also available to ensure the accuracy of previously drilled parts. Our standard products are optically measured, but when a greater level of accuracy is required, Lenox Laser can drill orifices to produce a specific flow rate for custom applications. Calculate a custom orifice diameter based on your specifications with our orifice calculator.

                On top of CCIT, Lenox Laser provides other services such as laser machining, laser engraving, and more. Lenox Laser also offers standard products for optical and flow applications. For any questions you have about our capabilities, please contact us.

We thank our customers for their continued support over the past 40 years. It is with your help that Lenox Laser continues pioneering in the small-hole industry.

SpaceX First Starship Launch

SpaceX has had quite a rich history and has come a long way since its maiden launch of the Falcon 1 rocket on September 28, 2008. Falcon 1 became the first privately funded liquid-fueled rocket to successfully reach orbit. In the following year, they became the first privately funded company to launch a satellite in orbit. Little did they know at the time, this would lead to something massive like the Starlink program. This program aims to launch a network of satellites designed to provide fast Internet speeds to areas without access. The Starlink program could also be used for military and government applications as well as other telecommunications.

In 2014, the now-famous Dragon crew was unveiled with its first successful launch six years later in 2020. The mission was successful in sending two astronauts into space to study aboard the International Space Station. This was particularly impressive given the challenges faced that year. Several Dragon crew missions are in the works for the near future.

SpaceX’s next challenging endeavor is the launch of its Starship program, which as of now, is tentatively set to launch in July of this year. Starship rockets would be reusable for long-duration cargo missions and passenger flights. The first obstacles include ensuring the program follows all government regulations from NASA, FAA, and other branches. Filings with the FCC began on May 13, 2021. If successful, SpaceX hopes to have a fully integrated continuous working network that would work together with Starlink.

Lenox Laser wishes SpaceX and all involved the greatest of success in this endeavor.
