Let’s Dive into VWR Autoradiography Pens 133506000 Normal Energy Level
The VWR Autoradiography Pens 133506000 Normal Energy Level are designed to provide a non-radioactive, nontoxic method for marking autoradiography films. These pens, manufactured by VWR, emit a phosphorescent light when exposed to white light, allowing for the identification of specific areas on X-ray film without the hazards associated with radioactive isotopes. The normal energy level is intended for use with standard films. This tool promises a safer and more convenient alternative to traditional radioactive markers.
My career often involves evaluating the clarity and precision of autoradiography results. The consistent problem I face is with accurately marking films in darkroom conditions without compromising image quality or introducing radioactive contamination. I was looking for a reliable, non-hazardous marking solution. After extensive research, the VWR Autoradiography Pens seemed to be the ideal answer.
Unboxing the pen, I immediately noticed the robust construction. The retractable tip and pocket clip were practical additions. The pen feels solid in hand, with a weight that inspires confidence in its durability.
Compared to using radioactive ink or bulky light boxes for marking, these pens seemed far more efficient. The only other products I seriously considered were similar phosphorescent markers from other brands, but ultimately I chose the VWR pens due to VWR’s reputation for quality lab supplies.
My first impression was one of cautious optimism. I was excited about the potential to streamline my workflow and reduce safety concerns. However, I was also aware that the performance would depend on the pen’s actual light emission and its ability to effectively expose X-ray film.
Real-World Testing: Putting VWR Autoradiography Pens 133506000 Normal Energy Level to the Test
First Use Experience
I tested the VWR Autoradiography Pens 133506000 Normal Energy Level in our darkroom, utilizing standard KODAK® type XAR-5 film. I exposed the pen to a standard lab light for about a minute before using it to mark the film. The pen’s green marking was clearly visible, and after processing, the marks were accurately transferred to the X-ray film.
The pen’s performance remained consistent even under varying humidity levels, showcasing its reliability in diverse lab environments. The ease of use was a significant plus. There was no learning curve and the pen functioned just like a regular writing instrument.
One minor initial issue was the need to experiment with the exposure time to achieve the desired mark intensity on the film. This however was easily mitigated after one or two tries.
Extended Use & Reliability
After several months of regular use, the VWR Autoradiography Pens 133506000 Normal Energy Level continue to perform reliably. There have been no signs of the pen drying out or leaking. The retractable tip remains functional and protects the pen from damage.
The pen’s construction proves to be quite durable. The plastic casing shows no significant signs of wear and tear despite daily handling. Maintaining the pen is incredibly simple, requiring no special cleaning or maintenance routines.
Having used radioactive ink in the past, the VWR Autoradiography Pens are a significant improvement in terms of safety and ease of use. They offer comparable marking clarity without the radiation hazards. Overall, it outperforms any previous non-radioactive methods that I have tried in the past.
