Conductive Pipette Tips Compatible with Bio-Rad EVOLIS in 300 µL and 1100 µL system-designated formats.
Puretest EVOLIS-compatible conductive pipette tips are designed for automated sample and reagent transfers on Bio-Rad EVOLIS microplate immunoassay systems. The family includes 300 µL and 1100 µL system-designated formats in 96-position automation racks, allowing laboratories, distributors and service providers to qualify one dependable second-source family for routine EVOLIS workflows.
Black conductive polypropylene supports the capacitive liquid-level and clot-detection functions used by the EVOLIS pipetting system. Consistent tip-cone geometry, rack registration and molded orifice quality are essential to dependable pickup, sealing, aspiration, dispense and ejection across the full 96-position rack.
Compatibility must be confirmed with the exact EVOLIS model, installed pipetting configuration, software method, rack carrier and liquid-handling protocol. Puretest recommends evaluation samples and method-specific qualification before routine, regulated or validated use.
An EVOLIS-compatible tip is part of a complete mechanical and sensing system. The upper cone must create a repeatable seal on the pipetting adapter; the conductive polymer must provide stable capacitive response; the shaft must maintain sufficient rigidity and labware clearance; and the distal orifice must support predictable aspiration and dispense behavior. The rack must also locate all 96 tips consistently so pickup force and tip height remain uniform across the instrument deck.
The 300 µL and 1100 µL variants use different shaft lengths and working-volume envelopes. They must not be interchanged only because both tips appear similar in a rack. Select the variant required by the EVOLIS method and confirm liquid class, immersion depth, transfer volume and destination-labware clearance during qualification.
| Specification | 300 µL Variant | 1100 µL Variant |
|---|---|---|
| System designation | 300 µL conductive tip | 1100 µL conductive tip; some compatible-tip catalogs describe this family as 1000 µL nominal |
| Primary use | Sample, predilution and reagent transfers within the validated method range | Large-volume transfers; EVOLIS literature describes usable system transfers up to 1000 µL |
| Material | Black conductive polypropylene | Black conductive polypropylene |
| Detection support | Capacitive liquid-level and clot-detection workflows | Capacitive liquid-level and clot-detection workflows |
| Rack format | 96 tips per automation rack | 96 tips per automation rack |
| Filter / sterility | Confirmed by exact quoted SKU | Confirmed by exact quoted SKU |
| Case quantity | Confirmed in quotation according to rack and packaging configuration | Confirmed in quotation according to rack and packaging configuration |
The values above describe the compatible product family and system context. Exact performance, purity, sterility, filter construction, case quantity and documents are controlled by the quoted Puretest SKU and should be confirmed before purchase.
Bio-Rad literature describes the EVOLIS platform as an automated pipettor, incubator, washer, reader and data-management system for EIA microplate assays. Its pipette-tip station accommodates five racks of 96 disposable tips and uses 300 µL or 1100 µL tip formats. Conductive tips support capacitive liquid-level and clot detection during automated sample and reagent processing.
| Qualification Item | Why It Matters | Recommended Check |
|---|---|---|
| Analyzer and configuration | EVOLIS family configurations and local methods may differ | Provide the exact analyzer model, serial/configuration and current tip reference |
| Tip volume | 300 µL and 1100 µL variants serve different transfer ranges | Match the method-defined tip family; do not substitute only by appearance |
| Rack seating and pickup | Registration and pickup force influence tip retention and walkaway reliability | Test every deck position and representative rows/columns |
| Conductive response | Capacitive sensing depends on material consistency and instrument settings | Verify liquid-level and clot-detection behavior with routine tubes and reagents |
| Liquid class | Viscosity, surface tension, foam and volatility affect transfer performance | Evaluate aspiration/dispense speed, depth, delay, air gap and residual volume |
| Ejection and waste path | Incomplete ejection can interrupt automated processing | Confirm clean release across a full rack and representative run |
For diagnostic and high-throughput work, order the exact configuration required by the laboratory quality system. Conductive material, filter design, sterility status and packaging method can change pickup behavior, usable capacity and contamination-control performance. Puretest therefore identifies each sellable configuration by SKU and supplies the documents applicable to that configuration.
| Information to Provide | Example / Purpose |
|---|---|
| Required volume | 300 µL or 1100 µL system-designated format |
| Analyzer information | EVOLIS model/configuration and current consumable reference |
| Filter and sterility | State whether filtered, sterile or specific purity documents are required |
| Method information | Critical volumes, sample/reagent type and detection requirements |
| Commercial requirement | Sample quantity, annual demand, destination, private label or distributor program |
No. This page covers conductive robotic tips intended for compatible Bio-Rad EVOLIS system contexts. Eppendorf epT.I.P.S. Motion products may use similar capacity labels, but platform compatibility must not be inferred from capacity or appearance.
Bio-Rad EVOLIS system literature uses the 1100 µL tip designation, while some compatible-tip suppliers describe the same large-volume family as 1000 µL nominal. Puretest uses 1100 µL system designation on this page and confirms the exact quoted SKU before order.
The black conductive polypropylene configuration is intended to support capacitive liquid-level and clot-detection workflows. Final performance must be verified on the customer’s exact analyzer and method.
Filter, sterility and purity requirements must be specified at quotation. Only the properties stated for the exact quoted SKU and its current documents should be used for validation or regulatory records.
Yes. Sample qualification is strongly recommended. Send the analyzer model, current tip reference, required volume, filter/sterility needs and target application so Puretest can prepare the correct sample plan.
For a fast compatibility review, include your EVOLIS model, current consumable reference or photographs, required 300 µL/1100 µL format, filter and sterility requirements, annual consumption and destination country.
