Phase Contrast Microscopy (PCM) laboratory analysis was the first service we offered to clients back in 2000 and we continue to provide reliable laboratory analysis services for over 22 years. We are NYSDOH ELAP certified and conveniently located just north of downtown Buffalo with a 24 hour drop box at our facility.



Laboratory Hours

Monday – Friday, 8:00am – 4:30pm | Saturday 8:00am - 12:00pm *as needed

As experienced environmental consultants and analytical professionals, we understand that construction projects and environmental emergencies do not always schedule themselves neatly into a 9 to 5 schedule. After-hours rush analysis services are available with prior authorization and for an additional fee.
