Heavy metals such as Cobalt (Co), Nickel (Ni), Mercury (Hg), and Lead (Pb) are present in low concentrations in base plastic resin. The resin which is later used to manufacture plastic lab consumables like bottles, tubes, pipettes tips etc.
Even though it is not directly added to the resin, it can be introduced via other additives such as stabilisers, colourants and other aids that are added to improve the durability of the material.
So consequently, the plastic consumables which are made out of such resin, contain low amounts of heavy metals.
This can alter the content of your precious media, reagents or buffers thereby influencing the outcome of your experiments
Bottles made of plastic resins are used to contain a wide variety of materials in many different settings. Especially in the biological and chemical fields, these materials can include high-value media, reagents, intermediates, or buffers; or critical components in sensitive assays.
Some of these types of materials can be extremely sensitive to reactive compounds that may be found in the plastic, even at low concentrations.
In such cases, the value of the bottle goes beyond the ability to maintain the closure seal and includes any manner in which the plastic container itself alters the contents.
Choose good quality storage bottles for your lab which have significantly low levels of heavy metals.
There are various regulations in place to keep a tab on toxic additives in plastic.
While plastic bottles are a generally inexpensive solution for storage of reagents or products, low-quality bottles may result in higher costs in the long run through the contamination and subsequent loss of high-value contents.
Part of the quality offering on these types of containers is the verification that they do not leach detrimental substances into the solutions contained within.
We put Accumax Media Bottles to the test against 24 elements and various global manufacturers.
- For Volatile compounds the samples were analysed on GC MS to evaluate all the possible fully volatile compounds from the respective product.
- For semi volatile and non-volatile compounds samples were given the treatment with different solvents in the ultrasonic bath for 6 hours and the analysed on LC-MS/MS and GC-MS
- For heavy metals, samples were digested in a digester and analysed on ICP-MS for 24 elements.
Here’s what we found
Remarkably, Accumax Media Bottles exhibited significantly lower levels of Nickel, Mercury, and Copper compared to the competitor’s bottle. Even for elements below the LOQ, Accumax PETG bottles demonstrated lower amounts of heavy metals, reinforcing their superiority over competitor products.
The exceptionally low levels of detectable metals underscore the superior quality of both the resin and the manufacturing process employed for Accumax Media bottles.
Accumax proudly provides an unparalleled selection of PETG/PET Media Bottles, crafted in ISO 13485:2003-certified manufacturing facilities. This diverse range caters to a broad spectrum of applications, budgets, and usage scales, ensuring best-in-class purity. Recognizing the paramount importance of quality compliance to our customers.
