250 µL robotic pipette tips for compatible Beckman Biomek automated liquid-handling workflows, supplied in Biomek-compatible rack configurations.
Puretest 250 µL robotic pipette tips are intended for general-purpose automated liquid handling 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.
P250-class usable capacity differs by Biomek platform and configuration. Beckman platform literature references approximately 230 µL non-filtered and 190 µL filtered for selected i-Series configurations, approximately 220 µL non-filtered and 125 µL filtered for selected FX/NX configurations, and approximately 190 µL for selected Span-8 use. The exact Puretest configuration must be qualified on the installed platform.
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 |
|---|---|---|
| Product family | P250 / 250 µL class | Nominal name is not a universal usable maximum |
| Selected i-Series reference | Approx. 230 µL non-filtered / 190 µL filtered | Verify pod/head and method |
| Selected FX/NX reference | Approx. 220 µL non-filtered / 125 µL filtered | Verify installed configuration |
| Selected Span-8 reference | Approx. 190 µL | Confirm channel, tip type and filter state |
| Conductivity | Conductive option may support compatible liquid-level detection | Confirm hardware, method and liquid |
| Filter / sterile / wide-bore | Configuration-dependent | Confirm each required option before ordering |
| Rack | Automation rack for compatible deck carriers | Confirm footprint, height, lid and pickup coordinates |
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 |
|---|---|---|
| Conductive | Methods using compatible liquid-level detection | Confirm installed platform and method |
| Non-filtered | Routine transfer and greater internal-volume flexibility | Confirm sterility and cleanliness documents |
| Filtered | Aerosol-barrier workflows | Platform-specific usable-volume limits apply |
| Wide-bore | Cells, beads or shear-sensitive samples when available | Confirm orifice geometry 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.
Because filtered capacity differs materially across platform families, quote and qualification requests should state the exact Biomek system, pod/head, filter requirement and highest critical method volume.
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.
Biomek-compatible tip selection commonly spans P20, P30/P30XL, P50, P250 and P1000 families. Platform, pod/head, filter state and method determine the appropriate capacity and usable range.
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 Beckman Biomek 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.
