200 µL Filtered Pipette Tips Compatible with Opentrons OT-2

Puretest 200 µL filtered tips are designed as an independent compatible option for Opentrons OT-2 P300 GEN2 liquid-handling workflows. They combine a clear polypropylene fluid path with an aerosol barrier for medium-volume transfers where contamination control is important.

The 200 µL filtered format is distinct from the 300 µL non-filtered format even though both are commonly associated with P300-class pipettes. Capacity, shaft geometry, filter position and liquid-class settings should therefore be selected and validated as a complete method rather than inferred from pipette name alone.

Important: Compatibility and performance must be established on the exact OT-2, P300 pipette, rack definition and protocol. Do not substitute a 200 µL filtered tip for a 300 µL non-filtered tip without method qualification.

Product Highlights

• 200 µL filtered format: recommended starting range approximately 5–200 µL.
• Aerosol barrier: supports contamination-conscious molecular and cell-based workflows.
• P300 compatibility target: for OT-2 P300 GEN2 1-channel and 8-channel pipettes.
• 96-position rack: automation-ready footprint after rack-definition and pickup qualification.
• Clear polypropylene: non-conductive material enables visual fluid inspection.
• Evaluation support: samples and available documents for laboratories and distributors.

Tip Structure and Functional Design

The filtered 200 µL tip uses a tapered clear polypropylene shaft and an internal hydrophobic barrier. Uniform cone dimensions support sealing on the pipette nozzle, while controlled wall thickness and orifice geometry help maintain predictable aspiration, dispense and blow-out behavior across the rack.

Medium-volume protocols frequently involve different liquid viscosities, mixing cycles and immersion depths. Qualification should therefore include both water-like and representative process liquids, the smallest and largest routine volumes, and the exact labware used in production.

Platform, Pipette and Rack Compatibility

Filtered, Non-Filtered and Packaging Configurations

This page covers the 200 µL filtered rack. The corresponding non-filtered OT-2 P300-family configuration is normally 300 µL and is listed separately. Confirm the required barrier, capacity and sterility/purity documentation before ordering.

Quality and Configuration Control

• Controlled molding and dimensional inspection support repeatable nozzle sealing, pickup height and ejection behavior across the 96-position rack.
• Transparent polypropylene provides direct visual confirmation of liquid movement and residual droplets; filtered versions include a hydrophobic barrier selected for the intended format.
• Specified sterile or purity-controlled supply is available only when confirmed for the selected item and supported by current lot documents.
• Lot identification, packaging integrity, dimensional drawings, material declarations and available quality documents can be supplied for the confirmed ordering configuration.
• Sterility, purity, filter, packaging and shelf-life claims apply only when they are listed on the current quotation, specification sheet and lot documentation.

Typical Applications

• PCR/qPCR and NGS preparation
• Reagent distribution and plate setup
• Sample normalization and dilution
• Cell-based assay liquid handling
• Automated mixing and serial dilution after validation

Recommended Qualification Workflow

1. Confirm the platform: identify the exact robot, pipette model, channel count and installed software or protocol definition.
2. Select the smallest suitable capacity: choose a tip whose qualified working range covers the intended transfer volume.
3. Confirm the configuration: filtered or non-filtered, rack or refill, sterile or non-sterile, and required purity documentation.
4. Run mechanical checks: evaluate full-rack pickup, nozzle sealing, tip height, labware clearance and clean ejection.
5. Run liquid-handling checks: confirm aspiration, dispense, residual volume, accuracy, precision and contamination control with representative liquids and labware.
6. Lock the approved item: record the final item code, tip configuration, rack definition and validated protocol settings before routine procurement.

Ordering Information

To receive the correct quotation, specify: OT-2 model, P300 pipette and channel count, 200 µL filtered requirement, rack quantity, sterile/purity requirements and required qualification documents. Puretest supports evaluation samples, distributor supply, recurring bulk orders and OEM/private-label programs for confirmed configurations.

Frequently Asked Questions

Why is the filtered tip 200 µL instead of 300 µL?

The filter occupies part of the internal volume and the filtered configuration is specified as a separate 200 µL format.

Can it be used on P300 pipettes?

It is designed for compatible P300 GEN2 single- and 8-channel workflows, subject to mechanical and liquid-handling qualification.

What happens if liquid reaches the filter?

A wetted filter can reduce recovery and change transfer behavior; review aspiration volume, immersion depth and liquid class.

Is this tip compatible with Flex?

No. OT-2 and Flex tips have different interfaces.

Can I request an evaluation rack?

Yes. Provide the robot, pipette, method volumes and representative liquids for the most useful evaluation.

Request Samples, Documents or a Quotation

Send your robot model, pipette model, channel count, target volume, filtered/non-filtered preference, rack/refill preference, sterility requirement and estimated annual demand. We will match the most appropriate configuration and provide available qualification documents.
