Laboratory Services

We offer a variety of laboratory analytical and quality assurance testing services for your life science businesses, researchers, and more.  We are always looking to expand our services by working on new projects. If you don’t see what you’re looking for here, just ask about our method development services.  Additionally, we offer laboratory rental so that you may work on your own research & development.

Method Development, Feasibility, & Standard Operating Procedures (SOP)

Our method development choices are based on our clients’ requests.  If you have a project you would like to pursue that has not previously been performed in our lab, the following fees apply:

  • Per hour development fee:  This will cover development and adaptation to our equipment. The development of SOPs for your procedure(s) is available upon request and will be billed at the same rate.
  • Per hour equipment use fee: This will cover associated equipment use costs.
  • Materials use fee: This will cover any materials necessary to develop and run the method.
  • Per sample pricing: The cost per sample is determined once your method has been established.

If our method development services are desired, please contact us to discuss your specific needs and obtain a quote for the requested work.
