200 µL filtered and non-filtered Flex-compatible pipette tips in 96-tip racks or refill configurations.
Puretest 200 µL tips are designed as independent compatible consumables for Opentrons Flex liquid-handling workflows. Filtered and non-filtered options support medium-volume plate setup, dilution and reagent distribution, while complete racks and refill-style configurations allow laboratories to select the packaging format that fits their workflow and sustainability goals.
The clear, non-conductive polypropylene tips are supplied in 96-position automation racks with a yellow identification component corresponding to the 200 µL family. The tip, mid-plate and rack base must be treated as a qualified system because pickup height, nozzle sealing, deck registration and ejection all affect automated performance.
Important: Flex tips are not interchangeable with OT-2 tips. These independent compatible consumables must be qualified with the exact Flex pipette, nozzle layout, rack definition, protocol and labware.
The 200 µL tip uses a controlled upper-cone interface, transparent shaft and molded distal orifice to support repeatable aspiration and dispense. Filtered versions incorporate a hydrophobic barrier above the normal liquid column; non-filtered versions retain an open internal air path. The correct choice depends on contamination-control needs, transfer volume and liquid class.
Flex pipettes may use single-, 8- or 96-channel nozzle layouts. Qualification should therefore verify the exact nozzle configuration, full or partial tip pickup, rack flatness, pickup force, labware clearance and ejection. Refill inserts must be evaluated in the intended base and should not be assumed compatible with unrelated racks.
| Parameter | Specification | Selection note |
|---|---|---|
| Nominal tip capacity | 200 µL | Select for approximately 5–200 µL transfers. |
| Recommended working range | 5–200 µL | Final performance depends on pipette, liquid class and method. |
| Tip material | Clear, non-conductive polypropylene | No capacitive liquid-level sensing function. |
| Filter options | Filtered or non-filtered | Choose according to aerosol-control and recovery requirements. |
| Rack format | 96 positions, Flex-compatible automation rack | Confirm rack definition, adapter and pickup height. |
| Identification color | yellow | Used to distinguish the 200 µL rack family. |
| Packaging | Complete racks or refill inserts | Confirm lid, base, sterility and refill configuration. |
| Autoclaving | Configuration-dependent; confirm current specification | Validate the complete rack/tip configuration and cycle before reuse-related procedures. |
| Item | Compatibility guidance | What to verify |
|---|---|---|
| Robot | Opentrons Flex | Robot software and deck configuration. |
| Pipettes | Flex 1-channel, 8-channel and 96-channel pipettes whose rated capacity covers the method volume | Rated pipette capacity, nozzle layout and pickup mode. |
| Rack / refill | 96-tip complete rack or confirmed refill/base | Labware definition, adapter, seating and Z offsets. |
| Filtered / non-filtered | Both configuration types available | Select and qualify as separate items. |
| Cross-platform use | Not compatible with OT-2 pipettes | Maintain separate Flex and OT-2 inventory. |
For the 200 µL family, choose filtered tips when the method requires an aerosol barrier and non-filtered tips when an open fluid path is preferred. Complete racks provide matched lid, mid-plate and base components; refill formats reduce rigid packaging but require a confirmed reusable base.
| Configuration | Best suited to | Supply / qualification note |
|---|---|---|
| 200 µL filtered rack | Contamination-conscious automated transfer | Complete 96-tip rack; keep liquid below the filter. |
| 200 µL filtered refill | Filtered workflows with reduced packaging | Confirm refill/base and supplied sterility configuration. |
| 200 µL non-filtered rack | Routine automated transfer | Complete 96-tip rack. |
| 200 µL non-filtered refill | Recurring use with reduced packaging | Requires confirmed base and seating. |
To receive the correct quotation, specify: Flex robot, pipette capacity, channel/nozzle configuration, 200 µL volume, filtered or non-filtered, complete rack or refill, sterility/purity requirements, required documents and annual demand. Puretest supports evaluation samples, distributor supply, recurring bulk orders and OEM/private-label programs for confirmed configurations.
No. They are independent compatible consumables and require qualification on the exact Flex system and method.
Yes, subject to the confirmed item code and current quotation. Treat each configuration as a separate qualification.
No. Flex and OT-2 tips use different mechanical and rack interfaces.
Complete racks include the matched rack components. Refills use a tip-bearing insert for a confirmed reusable base and may not include the same lid/base packaging.
Verify full or partial pickup, seal, ejection, deck registration, liquid-handling performance and contamination control with the exact robot, pipette and protocol.
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.
