Midwest Laboratories has a drop-off door outside of the main entrance on B Street. If you have samples that are not time sensitive, you can drop off samples there. If you do have time-sensitive samples: water, bacteria, etc. instructions are provided on the front door for contacting the appropriate people.
In addition, Saturdays – Receiving personnel are available on site between 9-12.00pm
If you ever have questions about dropping off sample, the best thing to do is call and contact someone about your situation. Any type of pre-notice really goes a long way in assuring proper hand-off of samples when they enter our building.
