--- title: SeqStudio Genetic Analyzer Cartridge and Service | ELIS.AL url: https://elis.al/seqstudio/ language: en updated: 2026-10-26 source: ELIS.AL (Euro Lab Instrument Services) --- # SeqStudio genetic analyzer: cartridge, consumables and service The SeqStudio keeps its four capillaries, polymer and anode buffer in one cartridge. Here is what to order, how long each part lasts and how to handle the cartridge so that it reaches its full life. Updated 26 October 2026 ## Key facts - A **4-capillary** benchtop analyzer for Sanger sequencing and fragment analysis. - The **SeqStudio Cartridge v2** (A41331) holds 28 cm capillaries, POP-1 polymer, the anode buffer and the polymer delivery system. - One cartridge runs up to **250 injections** (1,000 samples) and lasts **6 months** from its first installation. - The **cathode buffer container** (A33401, pack of 4) stays on the instrument for **2 weeks**. ## Consumables **Consumables for the SeqStudio** | Product | Details | For | OEM part no.

The software warns you when a limit is reached, and the manufacturer does not recommend running past it. ## Runs and throughput A run can be finished in as little as 30 minutes, with samples loaded in 96-well plates or 8-tube strips. The universal POP-1 polymer handles both sequencing and fragment analysis, so the same cartridge serves both applications without a change of polymer. The first-generation cartridge ran up to 125 injections; the v2 cartridge doubles that to 250. ## Service and support We help with installation, maintenance, troubleshooting and repairs, on site or remotely. Send the instrument serial number, the software version and a screenshot of the error or of the data, and we start with a remote diagnosis. See [genetic analyzer service](https://elis.al/genetic-analyzer-service/). ## Frequently asked questions ### How many injections does a SeqStudio cartridge last? The SeqStudio Cartridge v2 runs up to 250 injections, which is 1,000 samples. The first-generation cartridge ran up to 125 injections. ### How long can a cartridge stay in the instrument? Six months from its first installation, or until the expiry date, whichever comes first. ### Can I take the cartridge out and use it later? Yes. Fit the capillary protector and the optical cover, put the cartridge back in its white box and store it upright at 2–8 °C. ### How often do I replace the cathode buffer container? After two weeks on the instrument. The containers come in packs of four (A33401). ### Which polymer does the SeqStudio use? POP-1, a universal polymer for sequencing and fragment analysis. It is already inside the cartridge, so there is no separate polymer to order. ### Is the SeqStudio the same as the SeqStudio Flex? No. The SeqStudio has 4 capillaries in an all-in-one cartridge. The SeqStudio Flex has 8 or 24 capillaries with separate arrays, pouches and buffer containers. ## Related pages - ### [SeqStudio Flex](https://elis.al/seqstudio-flex/) Arrays, polymer, buffers and service for the SeqStudio 8 Flex and 24 Flex. - ### [Genetic analyzer service](https://elis.al/genetic-analyzer-service/) Preventive maintenance, calibration and repair for the 3500 series, 3130, 3730 and SeqStudio, on site or remotely. - ### [Compatibility chart](https://elis.al/guides/compatibility-chart/) Arrays, polymers and buffers for each Applied Biosystems genetic analyzer, with OEM part numbers. - ### [Contact](https://elis.al/contact/) Quote requests and contact details. ## Order for your SeqStudio Send your instrument model and the items you need.
