Product Details
The kit includes assorted color cap tubes and a free plastic rack, with each case containing four bags of each individual color: red, yellow, green, blue, and purple. The graduations on the tubes are printed in bold, easy-to-read black ink with an accuracy of +/-2%, while the large white marking area offers excellent contrast for identification. The polyethylene (HDPE) caps feature an integrated leak-proof seal and provide an easy-to-write-on flat surface. The tubes are designed with graduations molded into the conical bottom, making them ideal for pellet viewing and small volume quantification. The convenient zip-closure bag serves as a practical alternative to folding and taping opened bags. Users can easily color-code the assorted tubes for quick identification, customization, and enhanced productivity, with some reporting the use of color coding for different days of the week, lab members, or specific procedures. The accompanying plastic rack, made from polypropylene, is autoclavable, reusable, and recyclable, chemically resistant to drips, and designed to prevent sticking or freezing to surfaces, while its widely spaced design allows for easy retrieval of tubes.
