EET Laboratory Information

EET Laborotory EET has an on-site laboratory for analyzing incoming used antifreeze, in-process samples, and finished products to ensure high quality. The laboratory conducts a variety of physical and chemical tests.

These tests confirm that incoming used antifreeze shipments meet EET's acceptance criteria, verify that EET's processes are producing high-quality recycled ethylene glycol, and ensure that EET's fully reformulated antifreeze products meet or exceed all specifications for new antifreeze and engine coolants.
