Description
Dionex 6820.3300 syringe drive unit is supplied by Longi as a separately identified replacement item for industrial or laboratory equipment service. This listing identifies the Dionex 6820.3300 syringe drive unit for a Thermo Scientific U3000 autosampler. It is a separate product page because its 6820.3300 source reference, image set and stated test note differ from the FAB 22150-21001R drive-unit listing. Both may relate to U3000 equipment, but they are not described here as interchangeable.

This listing identifies the Dionex 6820.3300 syringe drive unit for a Thermo Scientific U3000 autosampler.

- Equipment family: U3000 autosampler
- Part reference: 6820.3300
- Product type: Autosampler syringe drive unit
- Condition note: Source record states the unit was bench tested before listing
- Purchase check: Compare 6820.3300 label, connectors, mechanical layout and U3000 configuration
Function and application context
A syringe drive unit forms part of the autosampler mechanism. It must align with the installed sample-handling assembly, mechanical mount and electrical connections. The product is offered for repair or replacement planning where the existing unit can be matched by its exact number and the visible construction shown in the product images.
How to match the correct part
Compare the 6820.3300 marking, plug positions, mounting points, drive geometry and the U3000 autosampler configuration with the removed part. Use both product photos for comparison. If the existing unit carries FAB 22150-21001R or another code, do not assume it is the same component simply because it belongs to the U3000 platform.
Model matching should always be completed before payment or installation. Product titles are written to make the individual reference easy to find, while the physical part, labels and photos remain the final evidence. Longi can review those visible details with the buyer before dispatch, but this does not replace the equipment manufacturer’s documentation or site safety procedure.
Condition and inspection information
The source record states that this stock unit was bench tested before it was listed. That note applies to this 6820.3300 unit only and does not replace final installation checks on the buyer’s instrument. Longi also reviews visible condition and secure packing before shipment. Normal evidence of prior installation can be visible on removed laboratory hardware.
For all used or removed equipment parts, buyers should allow for normal cosmetic evidence of storage or previous installation. The listing photographs are deliberately retained as part of the identification record. If a detail is important to your repair, ask for confirmation before ordering rather than assuming that a similar family name means the same revision.
Typical use
This product can assist laboratory maintenance engineers, chromatography service providers and equipment rebuilders restoring a Thermo Scientific/Dionex U3000 autosampler when they need the 6820.3300 syringe drive reference. It is not a complete autosampler and does not include unspecified accessories.
Before ordering
Send the old drive label, connector photos and U3000 equipment details before ordering. Longi can compare the visible evidence, confirm the pictured stock item and arrange protected shipment.
- Match the full model or part reference, not only the equipment family.
- Compare connectors, fittings, mounting points and the actual product images.
- Keep the removed part available until the replacement has been identified and installed.
- Confirm any required test, firmware, configuration or safety checks with the qualified installer.
Packing and international delivery
Longi packs electronic modules, laboratory components and control parts according to their shape and fragility. Protective material is used around boards, mechanical assemblies, cables and exposed connectors. Buyers can request a final model comparison or packing confirmation before shipment. International delivery is arranged after the order details, recipient information and any required quotation are confirmed.
FAQ
How is this listing distinguished from a similar product? What does the bench-test note mean? The original stock note reports a bench test for this 6820.3300 unit. It does not guarantee compatibility with every U3000 revision, so model and mechanical checks are still essential before purchase.
Can Longi confirm suitability? Longi can compare labels, photographs and visible installation details supplied by the buyer. The final decision must be based on the actual equipment, qualified service judgement and the precise part reference.
