Injection Molding of Polypropylene Culture Tube Covers for the Research Industry

Biomedical Polymers, Inc. injection molded polypropylene culture tube covers for use in research laboratories. The color-branded test tube caps, which are known as Kim-Kaps, come in six sizes (13 mm to 38 mm) and five colors.

We manufactured the part to the tightest tolerances, in this case, 0.13 mm. We also did visual and dimensional inspections to ensure the part quality met the customer’s specifications. We produced 1,600,000 parts, each of which weighs about 2 grams, and then bulk packaged the parts in 35 different configurations for shipment to our customer in Vineland, New Jersey. We provided a turnaround time of 2 to 3 weeks.

Please see below for the part dimensions and contact us directly for more information on our various capabilities.
