Sterile Does Not Necessarily Mean Clean

A good article helping to define conditions that may affect us.

"It is well established and indeed obvious that any medical device that punctures the skin or any medication that enters the bloodstream must be sterile. Sterilization procedures are fairly well established in the pharmaceutical and medical device industries and suitable testing is relatively straight-forward. What may not be as obvious is that these devices and products should also be free of foreign particles (i.e., clean). Control of unwanted particulate matter in products requires knowledge of potential sources of particles and processes that might generate particles to avoid potential problems. Identification of particulate matter is important in determining the root cause and to address safety concerns."

 
Well, I use depyrogenated, sterile vials, but USP pharma standards aren't something the RUO community strives to match, and it shouldn't.

If vendors are going to sell strictly under RUO, especially in the US, they need to test against RUO specifications, not USP pharma grade specifications. Vendors using anything labeled with USP testing are implying it’s safe for human use. Legally, they're advised to strictly keep all testing against RUO specifications or potentially alert the FDA.

USP specs have been defined by the life sciences community since the 70s, as greater than or equal to 95% purity, endotoxin less than or equal 1.0 EU/ug . Animal-free RUO grade and GMP RUO grade is classified as greater than or equal to 98% purity and Endo less than or equal to 0.1 EU/ug, although we know only some vendors care about endo concentration. So sterility aside, there are valid reasons to not use USP Pharma specs.

Where are you getting them? I just did a super quick Google search and at ThermoFisher 100 2mL vials are CRAZY expensive…like one empty vial costs more than a full vial of peps! If that;s the price…
Yeah, well, that ain't happening 😂
😂

On the positive side, no known obvious issues apparently from glass particles when breaking glass ampules (more common in other countries).

I use two sites for vials. If the Astor is out, I get them at the other one. Med & Lab supplies has 2 mL and 5 mL, The 2 mL actually hold close to 3 mL. Thermo is off the charts for everything.

Thanks- whoa, Astor has comparable pricing to Amazon and for a higher quality product! Much appreciated! 😁
