Sievers Standards Testimonials

Hundreds of pharmaceutical facilities worldwide rely on Sievers TOC Standards for calibration, validation and system suitability testing.  The testimonials below explain how our customers save precious time and minimize risks in daily operations by using Sievers Total Organic Carbon (TOC) Standards.

Quality Associate, Biopharmecutical Contract Manufacturer

“Thank you for helping us through this tough validation project.  The custom TOC standards you provided worked perfectly.  Your customer service is great!

Laboratory Manager, API Contract Manufacturer

“We used to make our own standards but we were having trouble at 500 ppb.  Sievers system suitability standards allow us to focus on getting our job done right… that’s analyzing samples and releasing water to manufacturing.”         

Team Leader, API Manufacturer

“Since we switched to Sievers TOC standards I don’t worry anymore about system suitability results.  We’re a high throughput laboratory and we’ve got many other things to worry about.”

Analytical Chemistry Manager, API Manufacturer 

“We run two shifts in the QC laboratory to support the production of a multi-million dollar drug.  We can’t afford any mistakes with system suitability testing because it would slow down production.  That’s why we use Sievers Standards.”

Team Leader, API Pilot Production Facility

“My Sievers 900 is so easy to use that I have my most junior technician running it.  But, if you don’t have the right technique, low-level TOC standards can be hard to make, so I make sure we use Sievers Standards for system suitability testing.”

Microbiology Goup Leader, Biotechnology Company

“We test system suitability once per month, so when we were making our own standards we were throwing away most of the stock solution.  That’s expensive.  We now get Sievers system suitability standards delivered once per month.  It’s great to be able to pop a set in the instrument and be able to use it right away.  No more wasted time or money!”
