--- title: 3500 Genetic Analyzer Consumables and Service | ELIS.AL url: https://elis.al/3500-genetic-analyzer/ language: en updated: 2026-10-26 source: ELIS.AL (Euro Lab Instrument Services) --- # 3500 and 3500xL genetic analyzers: consumables and service Everything the 3500 series needs in one place: new and regenerated capillary arrays, POP polymer, buffer containers, maintenance and repair for the 3500, 3500xL, 3500 Dx and 3500xL Dx. Updated 26 October 2026 ## Key facts - The 3500 and 3500 Dx use **8-capillary** arrays; the 3500xL and 3500xL Dx use **24-capillary** arrays, in 36 cm and 50 cm. - Arrays, polymer pouches and buffer containers carry **RFID tags** that the instrument reads to track use and expiry. - The Dx versions work in **IVD and RUO mode** and have their own array part numbers. - Polymer and buffer containers stay on the instrument for up to **14 days**; POP-7 for 7 days above 25 °C. ## Consumables for the 3500 series - ### [Capillary arrays](https://elis.al/capillary-arrays/) 8- and 24-capillary arrays in 36 cm and 50 cm, with OEM cross-references. - ### [Regenerated capillary arrays](https://elis.al/regenerated-capillary-arrays/) Original arrays cleaned, regenerated and fitted with a reprogrammed RFID tag, for much less than a new array. - ### [POP-7, POP-6 and POP-4 polymer](https://elis.al/pop-polymer/) Pouches for 96, 384 or 960 samples, with storage and on-instrument limits. - ### [Buffer containers and conditioning reagent](https://elis.al/buffers-reagents/) Anode and cathode buffer containers and the conditioning reagent pouch. ## Arrays, polymer and buffers by model **Consumables for the 3500 series** | Instrument | Capillaries | Capillary arrays | Polymer | Buffers | |---|---|---|---|---| | 3500 Genetic Analyzer | 8 | 36 cm `4404683` / 50 cm `4404685` | POP-4, POP-6, POP-7 pouches | Anode and cathode buffer containers / `ABC 4393927` / `CBC 4408256` / Conditioning reagent pouch / `4393718` | | 3500xL Genetic Analyzer | 24 | 36 cm `4404687` / 50 cm `4404689` | POP-4, POP-6, POP-7 pouches | Anode and cathode buffer containers / `ABC 4393927` / `CBC 4408256` / Conditioning reagent pouch / `4393718` | | 3500 Dx Genetic Analyzer | 8 | 36 cm `4404682` / 50 cm `4404684` | POP pouches (Dx versions for IVD work) | Anode and cathode buffer containers (Dx versions for IVD work) | | 3500xL Dx Genetic Analyzer | 24 | 36 cm `4404686` / 50 cm `4404688` | POP pouches (Dx versions for IVD work) | Anode and cathode buffer containers (Dx versions for IVD work) | OEM part numbers are shown for cross-reference only, so you can match what your instrument uses today. ## 3500 Dx and 3500xL Dx The Dx versions are built for diagnostic laboratories. They run in IVD mode for diagnostic work and in RUO mode for research and method development, and their capillary arrays have their own part numbers: 4404682 and 4404684 for the 3500 Dx, 4404686 and 4404688 for the 3500xL Dx. For IVD work, use the consumables your validated method specifies. We service both versions and regenerate Dx arrays online. ## Maintenance at a glance - **Every day the instrument runs:** check the consumable status, look for bubbles and leaks, and keep the top of the cathode buffer container dry. - **At least every 14 days:** replace the polymer and both buffer containers. - **Every month:** flush the polymer pump and the water trap. - **After every array change:** run spatial and spectral calibrations. - **Once a year:** preventive maintenance and a performance check. The printable [maintenance checklist](https://elis.al/guides/maintenance-checklist/) lists every task, and the [troubleshooting guide](https://elis.al/guides/3500-troubleshooting/) covers spikes, low signal, broad peaks and unstable current. ## Service for the 3500 series We carry out preventive maintenance, calibrations and repairs on site or remotely, and send a written report with the values measured. See [genetic analyzer service](https://elis.al/genetic-analyzer-service/) for what a visit includes, and [online regeneration](https://elis.al/regenerated-capillary-arrays/#online) if your arrays have reached their RFID limit. ## Frequently asked questions ### Which capillary array does my 3500 need? The 3500 and 3500 Dx take an 8-capillary array, the 3500xL and 3500xL Dx a 24-capillary array. Choose 36 cm for fast runs and most fragment analysis, and 50 cm for long sequencing reads. ### What does the RFID tag on 3500 consumables do? It stores the part number, lot, expiry date and use of the array, pouch or buffer container. The instrument reads it, tracks injections and days on the instrument, and warns you when an item is expired or used up. ### How long can polymer and buffers stay on a 3500? Up to 14 days at or below 25 °C. Above 25 °C, replace POP-7 after 7 days. The anode and cathode buffer containers also stay on for up to 14 days. ### Can I use 3130 or 3730 consumables on a 3500? No. The 3500 series uses its own arrays and RFID-tagged polymer pouches and buffer containers, while the 3130 and 3730 series use different arrays and polymer bottles. ### Do you have regenerated arrays for the 3500xL? Yes. We supply regenerated 24-capillary arrays for the 3500xL in 36 cm and 50 cm, as well as 8-capillary arrays for the 3500. ### Can a 3500 problem be solved remotely? Often, yes. Many problems can be diagnosed from the error message, the instrument logs and the electropherogram, and simple fixes can be guided online. Repairs and preventive maintenance are done on site. ## Related pages - ### [Capillary arrays](https://elis.al/capillary-arrays/) 8- and 24-capillary arrays for the 3500 and 3500xL in 36 cm and 50 cm, with installation and storage tips. - ### [Regenerated arrays](https://elis.al/regenerated-capillary-arrays/) Regenerated arrays for the 3500, 3500xL, 3130 and 3130xl, and online regeneration with a kit and remote support. - ### [POP polymers](https://elis.al/pop-polymer/) POP-7, POP-6 and POP-4 pouches in 96, 384 and 960 samples, and how to choose between them. - ### [3500 troubleshooting guide](https://elis.al/guides/3500-troubleshooting/) Likely causes and fixes for spikes, weak signal, broad peaks, pull-up, current errors and failed calibrations. ## Order for your 3500 Send your instrument model and the items you need.
