250 µL robotic pipette tips for compatible Agilent Bravo automated liquid-handling workflows, supplied in 96-format rack configurations.
Puretest 250 µL robotic pipette tips are intended for general-purpose automated transfers across plate preparation, sample processing and reagent distribution. The page is structured for automation engineers, laboratory managers, procurement teams and distributors who need more than a generic statement that a tip “fits” an instrument.
This family is positioned for compatible Agilent Bravo workflows using a 96LT pipetting head and 96-format tip racks. Agilent platform literature associates the 250 µL family with an approximate 2–250 µL operating range. Final performance depends on the selected Puretest tip configuration, liquid class, source and destination labware and liquid properties.
Automated pipetting performance depends on the complete setup: platform, installed head or channel, tip cone interface, rack and carrier, software tip definition, liquid class, source vessel, destination labware and liquid properties. Puretest recommends sample qualification with the intended method before routine or validated use.
A robotic tip must perform as part of a mechanical and fluidic system. Cone-interface consistency influences sealing and pressure behavior; shaft geometry affects access to labware; the distal section influences residual liquid and dispense behavior; and rack registration determines reliable multi-channel pickup. Filter placement, orifice size and conductive material can each change usable volume or liquid-class performance.
Qualification should therefore evaluate the exact sellable configuration rather than a family photograph alone. If a method changes from non-filtered to filtered, standard to wide-bore, clear to conductive or non-sterile to sterile supply, document the change and repeat the relevant fit and performance checks.
| Specification | Current Family Profile | Qualification / Ordering Note |
|---|---|---|
| Nominal family | 250 µL | Select according to critical transfer volumes and head configuration |
| Platform literature range | Approximately 2–250 µL | Platform reference only; customer qualification is required |
| Rack format | 96-format | Confirm carrier, rack height and lid clearance |
| Pipetting-head context | Compatible Bravo 96LT workflows | Provide the installed head and software method |
| Material | Laboratory-grade polypropylene; exact color/configuration by SKU | Confirm conductive requirement if applicable |
| Filter / sterile | Configuration-dependent | Confirm aerosol barrier, irradiation/wrapping and lot documents |
| Wide-bore | May be available for suitable workflows | Confirm orifice geometry and required sample type |
Values referenced from platform literature describe the automation context, not a blanket performance guarantee for every Puretest SKU. Puretest will confirm the selected product configuration and available documents in the quotation.

| Qualification Item | Why It Matters | Recommended Check |
|---|---|---|
| Platform and pipetting head | The same brand may use different heads, channels and tip definitions | Provide exact platform, head/pod/channel and software method |
| Rack and carrier | Footprint, height and registration affect pickup | Check carrier, deck coordinates, lid clearance and rack seating |
| Pickup and seal | Seal quality affects pressure, accuracy and retention | Verify all active channels for pickup, straightness, seal and ejection |
| Liquid class | Viscosity, volatility, surface tension and foaming affect performance | Optimize speed, delay, immersion depth, pre-wet, air gaps and tip touch |
| Critical volumes | Nominal family names do not guarantee every transfer point | Test minimum, routine and maximum critical method volumes |
| Variant change | Filter, wide-bore, conductivity and material alter behavior | Qualify every materially different configuration |
For second-source qualification, provide the exact platform, installed head/pod/channel, current tip reference or drawing when available, rack/carrier, target volumes, liquids, filter and sterility needs and annual consumption. This reduces the risk of selecting a tip based on brand name alone.
| Configuration | Typical Reason to Select | What to Confirm |
|---|---|---|
| Standard non-filtered | Routine aqueous transfer and maximum internal-volume flexibility | Confirm sterility and rack configuration |
| Filtered | Aerosol-barrier or contamination-sensitive methods | Usable volume and filter material are SKU-dependent |
| Sterile | Contamination-controlled workflows | Confirm irradiation, wrapping and current lot documents |
| Wide-bore | Cells, beads or shear-sensitive samples | Validate retention, orifice and liquid class |
Not every option is necessarily available in every volume and rack combination. The final quotation should identify material, conductivity, filter state, sterility, rack format, wrapping, case quantity and required technical documents.
For general-purpose transfers, optimize aspiration and dispense speed, air gaps, delays, immersion depth, tip touch and mixing cycles for the actual reagent and plate geometry. Wide-bore and filtered variants may require different liquid classes.
Automation consumables may require product specifications, material information, irradiation or sterility records, lot traceability, certificate of analysis and RNase/DNase or pyrogen/endotoxin declarations. Availability and limits depend on the exact SKU and current production configuration.
Do not transfer a claim from another volume, material or package format. State the required documents in the RFQ so Puretest can confirm the applicable specification before order placement. Customers remain responsible for final qualification in regulated or validated workflows.
Racked robotic tips can be supplied in configurations appropriate to the selected platform and market. Confirm rack footprint, lid, wrapping, sterile state, label, barcode or lot-data needs, case quantity and pallet/carton requirements. Supply planning can include evaluation lots, production batches, annual forecasts and safety stock.
For international orders, provide delivery country, forecast, preferred shipping terms if known and any required import or technical documents. Configuration, minimum order quantity and lead time will be confirmed during quotation.
Agilent Bravo tip families commonly include 10, 30, 70 and 250 µL capacities. Select the smallest capacity that comfortably covers the validated method range and match the rack format to the installed head and carrier.
Choose the smallest capacity that comfortably covers the validated transfer range, but match capacity to the installed head and rack format. A protocol spanning substantially different volumes may benefit from more than one tip family.
Puretest supports laboratories, automation integrators, distributors and private-label buyers serving Europe, North America and other international markets. Programs can cover evaluation samples, annual demand, safety stock, carton configuration, labels, artwork, lot information and shipping documents.
OEM/private-label availability is subject to configuration, minimum order quantity, forecast, artwork and lead-time review. Compatibility should remain accurately described; private labeling does not remove the need for customer-side method qualification.
No. They are Puretest-manufactured robotic pipette tips designed for compatibility with specified Agilent Bravo workflows. Puretest is not affiliated with or endorsed by the instrument manufacturer.
No. Usable range depends on platform, head/channel, filter, internal geometry, liquid class and application. Use the family as a selection starting point and validate critical transfer volumes.
Provide the exact instrument, installed head/pod/channel, rack/carrier and current tip reference when available. Test a sample for pickup, sealing, ejection and liquid-handling performance.
Availability is configuration-dependent. State filter, sterility, wrapping and required documents in the RFQ so the exact SKU can be confirmed.
Do not assume so. A filter changes usable internal space and may affect fluid behavior. Qualify the filtered configuration separately.
Only when the validated method uses a compatible conductive liquid-level-detection strategy or another requirement specifies conductive material. Confirm platform hardware and method settings.
Yes. Sample evaluation is recommended before routine use, especially for a new method or second-source qualification.
