Tired of plastic waste in the lab? So are we. Polycarbin's Beta Carbin program is a mailback service for a broad range of non-infectious, non-hazardous, rigid lab plastics. Simply sort plastics into the Clear and Color Carbins. Once full, use the prepaid return labels to ship them back to Polycarbin. From here, users can track their efforts with Polycarbin's data platform, the Carbin Counter. Clear and Color Carbins are sold separately. To get started, we recommend a 5 pack of each Clear (5000014326) and Color (5000014327) Carbins. Beta Carbins should come with prepaid return labels affixed to each box.
