Flow Cell (R10.3)

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.

A MinION Flow Cell (R10.3) is a consumable used with MinION and GridION devices. It contains the proprietary sensor array, Application-Specific Integrated Circuit (ASIC), and R10 nanopores are suitable only for experiments with the Ligation Sequencing Kit (SQK-LSK109). The pore contains a double reader-head, and 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.

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 ~48 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:

MinION and GridION Flow Cells are packed individually; however, bulk order options are available. All orders can be spilt 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 products 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:

Please store your flow cells as follows:

  • 2-8° C: flow cells can be stored, unopened, at 2-8° C for 12 weeks.

We recommend you check your flow cell before preparing your DNA/RNA 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.


MinION and GridION Flow Cells are provided in a sealed pouch and are shipped at constant temperature.

The latest flow cell packaging enables users to store flow cells at room temperature for up to one month (when the pack is unopened).

For longer term storage it is recommended that they are kept, unopened, at 2-8° C.

Prior to use, the flow cell can be checked by performing a “Flow Cell Check” script using MinKNOW (the MinION and GridION device software). The Flow Cell Check will report the number of nanopores available for sequencing.

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 MinION 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 800 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.

What's in the box

MinION flow cells are shipped in a sealed pouch.

Flow cell packaging

This packaging also serves as the flow cell returns kit. Users are requested to return their flow cells after use so that they can be responsibly recycled by Oxford Nanopore Technologies.


Oxford Nanopore's barcoding kits are designed to allow pooling and running multiple libraries on Oxford Nanopore devices. The barcoding kits compatible with R10 flow cells are:

Ligation-based PCR barcoding:

Native Barcoding (PCR-free):

Alternatively, the Wash Kit allows sequential runs of multiple sequencing libraries in the same flow cell. It works by washing out the first library, and refreshing the system ready for a subsequent library to be loaded. This procedure provides the opportunity to utilise the same flow cell a number of times, maximising the available run time particularly for cases where less data per library is required. Following the wash step, Storage Buffer is introduced into the flow cell, allowing storage of the flow cell before subsequent library addition.


R10.3 flow cells are suitable for use with the Ligation Sequencing Kit (SQK-LSK109) only.
