Everyone has been told to be “safe” since they were kids, but why is it so important for those working in a lab to hear it repeatedly?
The liquids in solvent and waste containers can be extremely dangerous. Laboratory workers often do not know which toxic vapors and gases can emerge from HPLC/UHPLC solvent containers, which can potentially cause serious harm to themselves and others. SecurityCAP™ protects the health of lab workers and visitors by preventing hazardous solvents and vapors from leaving solvent reservoirs.
How Does This Work?
The SecurityCAP solvent/eluent caps utilize a filter with an integrated one-way valve that protects lab air quality from hazardous vapors and gases that can leave the solvent container. The solvent filter also incorporates a PTFE membrane that captures dust, dirt, and other contaminants in the air and prevents them from entering the solvent/eluent container, protecting the solvents from bacterial growth. This protects both the chromatography results and HPLC/UHPLC systems.
The SecurityCAP solvent waste protection caps capture and store solvent waste safely. This allows for lab workers to be confident in knowing that volatile vapors are safely obtained, beyond fume cupboards or hoods. And compared to normal activated charcoal, SecurityCAP waste safety filters also absorb basic and acidic compounds, which provides extra protection for your lab.
Saves Lab Resources
Labs all over the world cap their solvent bottles differently and many cap/cover arrangements can dramatically alter HPLC/UHPLC results.
To compare the SecurityCAP with other solvent bottle covering methods, we studied four 1L bottles containing 5mM Ammonium Bicarbonate, and left them in a hood for seven days. We compared the SecurityCAP to an open top, aluminum foil wrapped bottle top, and a cap with two 10mm holes in the plastic material. The pH was checked before and after the experiment and the percent difference was calculated. All of the bottles contained HPLC tubing to simulate real world usage.
The SecurityCAP had the lowest changes in pH level than any other capping method. The open top cap had a 12.1% change in pH, the aluminum top had a 5% change in pH, while the closed top with two holes saw a 3.1% change, compared to the 1.7% pH change with SecurityCAP.
SecurityCAPs also reduce HPLC/UHPLC solvent expenses by minimizing solvent evaporation.
We filled 4 bottles with 1L of Methanol and capped them using the same methods as the pH study and left them in a hood for 10 days. The bottles were then weighed without the cap on a top loading balance. All bottles contained HPLC tubing to simulate real world usage. The results showed a drastic difference comparing 27.8% solvent loss with the open top cap and the 2% solvent loss with the punctured top cap. The SecurityCAP showed only .05% loss of solvent.
Not only does the SecurityCAP provide air quality and solvent spill protection to those working in a lab, but it saves the lab significant amount of funds and resources.
With all the benefits the SecurityCAP provides, it is also easy to install. Check out the image below to see for yourself!
The innovative SecurityCAP design prevents air intake and makes it easy to change solvent bottles without twisting tubes during the bottle exchange.
