50 µL Tecan-Compatible Robotic Pipette Tips for Automated Liquid Handling

Puretest 50 µL robotic pipette tips are designed for low-to-medium volume liquid handling that needs more working range than a 20 µL tip while preserving efficient reagent use. One product family combines the two material choices buyers most often need: a black conductive polypropylene tip for compatible capacitive liquid-level detection and a clear non-conductive polypropylene tip for visual method development or workflows that do not require conductive sensing.

Combining these variants on one page makes technical comparison and purchasing easier. Select the required material, rack style, sterility and documentation when requesting a sample or quotation. Because automated pipetting performance depends on the complete system, Puretest recommends qualification with the intended instrument arm, carrier, liquid class, source labware and destination plate before routine production use.

Product Highlights

• Two material options: conductive black and clear/natural polypropylene.
• Nominal capacity: 50 µL for low-to-medium volume liquid handling that needs more working range than a 20 µL tip while preserving efficient reagent use.
• Automation-focused fit: intended for compatible Tecan Freedom EVO LiHa and Fluent FCA workflows.
• Method flexibility: choose conductive sensing support or transparent visual inspection according to the protocol.
• Quality options: sterile and documented cleanliness configurations are available by SKU.
• Supply support: samples, batch documentation, OEM/private label and distributor programs are available.

Available Materials and Detection Options

Important: clear/natural tips are non-conductive and should not be described as providing capacitive liquid-level detection. Conductive tips can support that function only when the instrument, hardware and method are configured for it. This distinction should be included in the RFQ and method qualification.

Technical Specifications

The table describes the combined product family rather than promising that every option is available in every packaging combination. Puretest will confirm the selected configuration, current specification and supporting documents in the quotation.

Platform and Workflow Compatibility

These tips are positioned for compatible Tecan liquid-handling workflows, including Freedom EVO systems using the Liquid Handling Arm (LiHa) and Fluent platforms using a Flexible Channel Arm (FCA). Instrument model alone is not sufficient to guarantee method performance. Cone geometry, channel configuration, carrier type, rack height, deck position, tip definition and liquid class must all match the intended setup.

For a new method or second-source qualification, provide the instrument model, arm type, required volume, conductive or clear preference, rack format, sterility requirement and expected liquids. Puretest can then identify the most appropriate sample configuration for fit and performance testing.

Application Guide

The 50 µL family is particularly suitable for:

• assay setup and serial dilution
• sample normalization
• PCR and extraction workflow preparation
• reagent and buffer dispensing
• cell-based assay plate setup

The 50 µL format is useful when a method crosses the practical range of a low-volume tip but does not require a 200 µL tip. Validate aspiration speed, immersion depth and liquid-class settings with the actual reagent, plate and carrier configuration.

Method Setup and Qualification Recommendations

1. Confirm mechanical fit: check pickup, sealing, straightness, retention and ejection across all active channels.
2. Confirm rack and carrier fit: verify deck registration, rack height, lid clearance and pickup position.
3. Optimize the liquid class: evaluate aspiration/dispense speed, delays, immersion depth, air gaps, pre-wetting and tip touch.
4. Test representative liquids: include aqueous buffers and any viscous, volatile, foaming or low-surface-tension liquids used in the actual method.
5. Measure performance: verify accuracy, precision, residual volume, carryover risk and channel-to-channel consistency at critical transfer volumes.
6. Document the approved setup: record SKU, lot, instrument configuration and liquid-class version for change control.

Quality, Sterility and Documentation

Automated workflows often require more than a generic “fits the instrument” statement. Buyers may request product specifications, material information, irradiation or sterility records, cleanliness declarations, lot traceability and a certificate of analysis where applicable. Availability depends on the selected SKU and current production configuration.

Do not assume that a claim for one material or pack format automatically applies to every variant. State required documentation in the RFQ so Puretest can confirm it before order placement. For regulated or validated workflows, the customer remains responsible for final qualification in the intended application.

Packaging and Rack Options

Available in racked configurations, including an SBS-footprint option for compatible automated carriers. Confirm the exact rack, lid, sterile wrap and case pack during quotation.

International Supply, OEM and Distributor Support

Puretest supports laboratories, automation integrators, distributors and private-label buyers in Europe, North America and other international markets. Supply discussions can cover evaluation samples, annual demand, safety stock, carton configuration, labeling, barcode or lot information, OEM artwork and shipping documentation.

For the fastest quotation, include the expected annual quantity, delivery country, target instrument and arm, required volume, material color, sensing requirement, rack format, sterility, filter requirement and documentation list.

Choosing the Right Tecan-Compatible Tip Volume

• 20 µL Tecan-compatible robotic tips — low-volume transfers where controlled aspiration, consistent tip pickup and reduced reagent consumption are important.
• 50 µL Tecan-compatible robotic tips — low-to-medium volume liquid handling that needs more working range than a 20 µL tip while preserving efficient reagent use.
• 200 µL Tecan-compatible robotic tips — general-purpose automated transfers across plate preparation, sample processing and reagent distribution workflows.
• 1000 µL Tecan-compatible robotic tips — larger-volume automated transfers of buffers, media, wash solutions and other routine laboratory liquids.

Choose the smallest capacity that covers the validated transfer range without forcing the method beyond its stable operating window. When a protocol spans several volume ranges, using more than one tip capacity may improve precision and reduce reagent consumption.

Frequently Asked Questions

Are the conductive and clear tips the same product?

They share the same nominal 50 µL family and intended automation use, but the material and sensing behavior differ. The black conductive variant can support capacitive liquid-level detection on a correctly configured compatible system. The clear polypropylene variant is non-conductive and allows visual inspection.

Are these original Tecan tips?

No. They are Puretest-manufactured robotic pipette tips designed for compatibility with specified Tecan workflows. A compatibility sample should be qualified before routine use.

Which Tecan platforms are supported?

The product is positioned for compatible Freedom EVO LiHa and Fluent FCA workflows. Exact suitability depends on instrument configuration, carrier, tip definition and method. Provide those details when requesting a sample.

Can I use the clear tips for capacitive liquid-level detection?

Clear/natural polypropylene tips are non-conductive and should not be relied upon for conductive capacitive sensing. Use the detection strategy validated for your instrument method, or select the conductive black variant.

Are sterile tips available?

A gamma-irradiated sterile configuration is available for qualified SKUs. Confirm the exact material and packaging combination and request current lot documentation with the quotation.

Are RNase-, DNase- and pyrogen-related documents available?

Cleanliness documentation is available for qualified configurations. Ask Puretest to confirm the current declaration or certificate for the specific SKU and lot you intend to purchase.

Can I order samples before a bulk purchase?

Yes. Sample qualification is recommended to confirm pickup, sealing, ejection, rack/carrier fit and liquid-handling performance with the intended method.

Do you provide OEM or private-label packaging?

OEM and private-label programs are available subject to configuration, artwork, MOQ and lead-time review. Provide the target market, annual forecast and packaging requirements for evaluation.
