Additional Information
Symmetry C18 Column, 300Å, 5 µm, 4.6 mm X 150 mm, 1/pk Get confidence in the long-term compliance of your HPLC methods by using the Symmetry C18 Column, which continues to set the standard for HPLC drug assays. By investing in the lab equipment, there is no need to compromise on peak shape, selectivity, column-to-column, and batch-to-batch reproducibility, or other critical performance characteristics. By using the Symmetry C18 Column, you can achieve outstanding reproducibility year on year. The analytical column eliminates the need to continuously revalidate and redevelop methods with each batch of new columns. This helps to save labor costs that add up with the traditional analytical columns that require QC column testing. The Symmetry C18 Column offers the tightest specifications in the market to provide consistent results every time, as it is manufactured in our cGMP, ISO9001, and ISO13485 certified facilities where each step is monitored and strictest conditions are followed. The column with high purity raw materials, using column packing procedures that result in the most reproducible HPLC column. Using the Symmetry C18 columns, you can maximize efficiency and precision in your lab with the monofunctionally bonded C18 ligand that is present in the lab equipment. The column includes a high purity base-deactivated silica for the highest reproducibility. Additionally, the Symmetry column also exhibits the narrowest ligand surface coverage (ligand density) specifications in the industry, which results in minimal shifts in resolution and more reproducible batch-to-batch results. The Symmetry C18 Column is supplied with a three-page Certificate of Analysis which contains the specifications as well as the results of 22 critical tests that each column needs to clear before being quality assured. To invest in the highest quality supplies that help in increasing your productivity and efficiency, shop for lab equipment directly from our catalog or online store. You may also want to check out the Symmetry C18 Sentry Guard Cartridge, 300Å, 5 µm, 3.9 mm X 20 mm, 2/pk , which is made using the identical packing materials used in the Symmetry C18 Column and specially designed to protect the analytical column from any unwanted chemical or particulate materials.

FAQ
What Is The Difference Between Repeatability And Reproducibility? Repeatability measures the variation in measurements taken by a single instrument or person under the same conditions, while reproducibility measures whether an entire study or experiment can be reproduced in its entirety.
