Who Is Covered?

The warranty applies to users of the Instrument, regardless of whether they are the original purchaser, provided the Instrument is installed and maintained according to Sierra Biosystems requirements.

When Does the Warranty Start and End?

  • The warranty lasts one (1) year.

  • Coverage begins on the date of installation, as long as installation is performed by a certified K&A or Sierra Biosystems installer.

What Is Covered Under Warranty?

  • Damage from unauthorized service or repair

Included Spare Parts

Instruments are shipped with a limited set of spare consumable parts (such as valves, seals, or bottle caps). These spare parts are provided to support routine maintenance and help users operate the instrument reliably during the warranty period.

The inclusion of spare parts does not indicate that consumables are covered under warranty or that additional replacements will be provided beyond what is initially supplied, unless otherwise stated.

User Responsibilities (Required Maintenance)

To keep the warranty valid, users must:

  • Regularly drain water from the compressor

  • Ensure the compressor contains sufficient oil

  • Avoid leaving amidites or reagents in lines where crystallization may occur

  • Perform routine flow tests (recommended)

  • Make reasonable attempts to resolve minor issues (such as replacing valves or bottle caps) using resources available in the Sierra Biosystems Support Center

Failure to follow these requirements may void warranty coverage.

Software, Data, and Research Use

  • Software provided with the Instrument is supplied “as is”, unless otherwise stated

  • Sierra Biosystems is not responsible for:

    • Data loss or corruption

    • Sequence design errors

    • Experimental or research outcomes.

Environmental and Facility Requirements

Warranty coverage does not apply to damage caused by:

How Long Does Warranty Service Take?

Sierra Biosystems makes reasonable efforts to complete warranty service within two (2) weeks, when possible. Timing may vary depending on location, parts availability, and issue complexity.

International Coverage

Replacement Parts and Repairs

  • Replacement parts or instruments may be new or refurbished and will be functionally equivalent

  • Repairs or replacements do not extend or restart the original warranty period

Warranty Extensions

Some users may purchase a Warranty Extension to extend coverage beyond the initial one-year warranty.

Please note:

  • Warranty extensions are purchased separately

  • Extensions apply only to the specific Instrument purchased

  • Extensions extend the duration, not the scope, of coverage unless explicitly stated in the extension agreement

To the extent permitted by law:

  • Any implied warranties (including merchantability or fitness for a particular purpose) are limited to the duration of the express warranty
