PromethION Flow Cell Packs

R10.3 is our newest nanopore chemistry, providing improved homopolymer performance. It is suitable for experiments where high consensus accuracy is required. It can provide data with 1D accuracies up to 95% and consensus accuracies over Q50. As a new product it will be rapidly iterating, and it is currently only recommended for our DNA ligation sequencing chemistry.

This product has a lead time of 5 weeks

How it works:

A user simply adds their prepared library to the flow cell and starts their sequencing experiment.

Data is accumulated over time as DNA is sequenced by the nanopores. Individual read files are generated and are immediately available for analysis.

As data is streamed in real-time, a user can choose to stop a run as soon as sufficient data is gathered. A flow cell contains sufficient buffer to run for ~64 hours (under optimal conditions) and a user can choose to run continuously or run, stop, wash, and load a new sample until the buffer and nanopores are exhausted.

Shipping and logistics:

PromethION Flow Cells are packaged in packs of 4. The flow cells are shipped in multiple set sizes, depending on the size of your project. All orders can be split for delivery to best suit your needs.

Flow cells and kits are shipped together in a temperature-controlled shipping box.

The packaging is designed to protect the flow cells from freezing. Flow cells are stable at ambient temperatures for 30 days and sequencing kits are stable at room temperature for up to seven days, so users should not be concerned about their product should they arrive at ambient temperature.

Products are shipped to customers within the USA and EU Monday to Thursday. Shipments to Canada, Norway, Korea and Japan are expedited Monday to Wednesday; with Australia and New Zealand leaving our warehouses on a Friday. Shipments to the rest of the world are made on Mondays to allow the full working week for packages to arrive.

The delivery charges are calculated when a quote is raised or during checkout. Once an order is made, the delivery ID and delivery information can be tracked in the Store.

Storage and stability:

Flow cells can be stored at room temperature for up to 30 days. For longer-term storage, place at 2-8˚C

We recommend you check your flow cell before preparing your library as part of the warranty process.

Flow cell returns:

We ask customers to return their used flow cells to Oxford Nanopore Technologies for recycling. For more information, please see the "Flow cell returns" section.


Prior to use, a Flow Cell Check should be run on the flow cell. This checks that the environment for the flow cell chemistry has been maintained during shipping.

PromethION Flow Cells are provided in a sealed pouch and are shipped at a constant temperature. For long-term storage, it is recommended that they are kept in an environment not prone to large temperature fluctuations. The flow cells should be stored flat.

Once the Flow Cell Check has been performed satisfactorily, the flow cell is ready to be used for experiments. The exact protocol and reagent kits used will depend on the experiment being run.

Please return your flow cells to Oxford Nanopore Technologies after use.

Safety and legal

Safety data sheet for PromethION Flow Cell buffer

Customers are required to perform a flow cell check within 3 months of purchase. Oxford Nanopore Technologies will replace any flow cell with fewer than 5000 nanopores, when the result is reported within two days of performing the flow cell check, and when the storage recommendations have been followed. We deem the useful life of this product to be 12 weeks from receipt by the customer.

There is a 1 year contract length on all consumables purchases.
