Crash Course Recap: Crosslinkable Polymers

The last E-BEAM Crash Course tackled the subject of crosslinkable polymers. But just what are crosslinkable polymers?

Ionizing radiation produced by the electron beam breaks bonds within the molecules of the polymers. With some polymers, these bonds reform in a beneficial way, which we call crosslinking. For example, polyethylene is a polymer that is relatively easy to crosslink (if you have an electron beam, that is ? ). In the polyethylene crosslinking process, a hydrogen atom is broken, allowing the carbon  backbone of the molecule to bond with the carbon backbone of an adjacent molecule. This imparts beneficial properties like: better abrasion resistance, less permeability, higher operating temperatures, and the ability to instantly know the winning numbers for the next jackpot lottery.

Crash Course Recap: The 4 Steps to Sterilization Validation

E-BEAM’s latest Crash Course walks the viewer through a quick overview of the four main steps to sterilization validation.

To be able to officially declare your medical device as sterile after processing, you must first perform a sterilization validation. Radiation sterilization methods, like e-beam, are monitored by the ISO 11137 standard. But don’t worry, both your sterilization provider and microbiology lab will help walk you through it!

E-BEAM Services adds a second accelerator in Cranbury, New Jersey

Cranbury, New Jersey – January 2018

E-BEAM Services, Inc. has announced a major addition to its electron beam sterilization capacity with a second high-powered electron beam accelerator in Cranbury, New Jersey. This accelerator is specially designed to serve the rapidly growing demand for electron beam sterilization in the medical device and pharmaceutical industries.

This addition is timely, according to E-BEAM’s Director of Business Development, Bill Crilley, “because the number of medical devices and pharmaceuticals being validated for ISO/FDA compliant sterilization is at an all-time high for E-BEAM Services.” Read More »

What is a dose map and how much does it cost?

A dose map, or dose distribution study, helps us determine if all of the product within your case is receiving the necessary sterilization dose. In this study, we take a measurement of the internal doses throughout a case of product.

The case of product is opened by E-BEAM Services, and our trained lab technicians place dosimeters at multiple locations, based on guidance provided in ISO 11137-3. We then run the case through the accelerator in a simulated production scenario, taking an additional measurement of the surface (or surfaces, in two-sided processing) of the case that faces the beam. Once the processing is complete, we read the dosimeters, using the surface reading as a reference dose. We identify the location of the minimum and maximum internal doses within the case, and then relate those to the surface dose using simple ratios. Read More »

Dear Karen: How many samples do I need for an e-beam material test?

 

Dear Karen,

I am a new startup company, and am trying to get my product validated for e-beam sterilization. How many samples do I need to send you for the material test? And, while we’re talking about material tests….what are they?

Sincerely,

Material Girl Read More »

Hydrogel Crosslinking

pharmaceutical-sterilization

Although we may not recognize them for what they are, hydrogels are very useful and are becoming more and more common each day. We can find hydrogels in a wide variety of today’s products, from medical devices to contact lenses to your lunchtime Jell-O snackpack.

So, what exactly is a hydrogel? Read More »

Increasing UHMWPE abrasion resistance with electron beam processing

Are you looking for a tough material with high abrasion resistance? The e-beam process can greatly improve the abrasion resistance of Ultra High Molecular Weight Polyethylene.

Ultra High Molecular Weight Polyethylene is also known as UHMWPE. It’s pretty cool stuff. As the name implies, it is polyethylene with really long chains. In fact, it’s molecular weight range is typically 100 times more than high density polyethylene (HDPE)! This makes it naturally more resistant to abrasion and impact than your typical polyethylenes.

Dear Karen: E-beam vs Gamma Sterilization Dose

Dear Karen,

I have qualified my product for sterilization at a gamma facility, but am interested in transitioning to electron beam. I already know what dose my product needs for gamma sterilization. Is this dose going to be the same for e-beam sterilization?

Sincerely,

Max Dose (Name changed for privacy. And because I’m a sucker for puns.) Read More »

Throwback Thursday: Long-lasting barrier-resistant properties

With a show of hands, how many of you wear makeup on a daily basis? I myself never leave home (and actually rarely even walk around home by myself) without mascara and some form of gloss or lipstick. And in today’s world, a lot of us care a lot about what goes into our makeup. But how many of us think about what it takes to create quality packaging for our favorite blushes and contouring palettes? Read More »
