Our LTR tips are available for single-channel pipettes as well as 8, 10, or 12 multi-channel LTS/XLS pipettes. Oxford Lab Products LTR tips are internally coated with hydrophobic, harm-free, low-retention resins to minimize sample retention. These tips are free of heavy metals and are free of RNase, DNase, cytotoxic materials, PCR inhibitors, endotoxins, and pyrogens to avoid sample contamination. The design of Oxford Lab Products LTR Tips also includes a fine-point end that yields additional accuracy, precision, and consistency. All our LTR tips are quality tested by our in-house lab technicians. Our QC protocols ensure that all Oxford Lab Products LTR tips are manufactured to meet strict regulations that enable high-performance pipetting.
