Let’s work toward a world of environmental responsibility

Find out how we have helped businesses like yours achieve their goals.

  • I've been in the business for 10 years now, and that whole time they're the only lab we've worked with and we haven't had any reason to search elsewhere. They've kept us happy, and I think we look at Sterling Labs as being a vital part of our process.

  • I live in the city of Chicago (...) and they are at a physical location where sometimes it is convenient for me being 15 minutes away from the lab to go there and pick up containers and drop something off. So the location is helpful.

  • Among their strengths: data reliability, turnaround times, and pickups. Project managers are responsive and pretty helpful with their customer service. They are flexible –if we send them six samples, and then call later and ask them to prioritize some over others, they will do that.

  • Communication is really good. I can call or email and get an answer within minutes. 

  • They are centrally located within Chicagoland, and are easy to access (...) They also have been known to help us outside of regular hours, when other companies would not. We have been doing business with them for a very long time. Having consistent staff is important. They have had the same staff for a very long time and that is very meaningful. 

  • They give more personalized attention for smaller companies such as ourselves so we don’t get lost.  And we don't feel like a nuisance, if you will, compared to the bigger guys and their bigger accounts and the volumes they are used to receiving from customers. So that is a big positive as far as I am concerned. We are able to get a hold of someone on a routine basis and get the answers right away. 

  • The location is convenient, and the team, extremely responsive. Justin and Craig are workaholics and they are always going! 

  • The quality of Sterling Labs is outstanding. There are really no complaints that we've had on our end, or any reason to question the work that they do for us.

  • They do a great job. We do a lot of PCBs in oils and they run a modification of the method that most labs don't that provides a much better sensitivity for that analysis and so that is something that stands  out. They have gone beyond what the norm is to provide a more sensitive analysis. They have 24-7 service which most labs do not anymore. 

  • I think their customer service is wonderful, top notch. I think their knowledge and expertise is great. There are a lot of experts there that we rely on –they help us. (...) I really like working with them.
