Work Environment

The lab operates in a fast-paced, production-like environment where meeting client time frames and turnaround goals is a central part of the work.

The microbiology department is a relatively small team, working in a separate laboratory space from chemistry, which fosters close collaboration and clear communication.

The facility is modern and housed in a newer building, offering an organized, professional setting for laboratory work.
