The products we offer at ALCOLOCK are the best you’ll find in the industry. How do we know? Because we control the entire process and develop our own products. That way, we can control the quality from inception to production. We’ve never been satisfied with offering a single device or reselling an existing line of products. Instead, we’re wholly committed to immersing ourselves in the industry. We’re proud to have established a reputation for being experts in our field. We’ve stayed at the top of the industry by developing a wide range of high-quality products that span the entire gamut, from lab equipment to devices that aid program facilitators to the breathalyzers and products the consumer uses throughout their program. Our mouthpiece line is a part of the quality product offerings we’ve developed to make the road to license reinstatement and independence as easy as possible.

Mouthpiece Basics

Our mouthpieces are recyclable plastic mouthpieces designed to work with a wide variety of breathalyzers and ignition interlock devices. We wrap each mouthpiece in plastic packaging to ensure that every sample is sanitary. This minimizes the chance of false results and contaminated samples. Most of our mouthpieces come in packs of 25. You may purchase a higher quantity of mouthpieces for a discounted bulk rate.
