300 µL Sample Pipette Tips Compatible with Dynex DS2 and DSX

Puretest 300 µL sample pipette tips are designed as an independent compatible consumable for automated sample, standard and control transfers on DYNEX DS2, DS2 Elite and DSX ELISA systems. The blue tip format provides clear visual identification and is supplied in a 108-position sample-tip container for instrument loading.

The 300 µL sample tip is intended for approximately 10–300 µL transfers. It is not the same product as the 1300 µL reagent tip: the two formats use different capacities, instrument positions and workflow roles. The current page has therefore been rebuilt around the correct sample-tip specification rather than copying reagent-tip data.

Important: These are independent compatible consumables, not original DYNEX consumables. Confirm the exact instrument, software method, pipetting role and physical configuration, then qualify the selected item before routine, regulated or diagnostic use.

Product Highlights

• Correct sample-tip specification: 300 µL nominal capacity for approximately 10–300 µL sample transfers.
• 108-position container: optimized sample-tip layout for compatible DYNEX loading positions.
• Blue visual identification: helps distinguish sample tips from the clear 1300 µL reagent-tip family.
• DS2/DSX workflow target: for compatible DYNEX DS2, DS2 Elite and DSX sample-pipetting positions.
• Disposable polypropylene: consistent molded cone, shaft and orifice geometry for automated use.
• Qualification support: evaluation samples, drawings and available quality documents.

Tip Structure and Functional Design

The ribbed upper collar is designed to create a repeatable mechanical connection with the sample-pipetting adapter. The long, narrow shaft supports access to sample tubes and microplate wells, while the controlled distal orifice helps maintain consistent aspiration and dispense behavior across the 108-position container.

A DYNEX sample-tip container is part of the instrument interface. Tip pitch, container flatness, pickup height and lid or carrier geometry can influence loading and unattended processing. Qualification should include the first and last positions, partially depleted containers, representative sample tubes and the full method volume range.

Technical Specifications and Selection Notes

Platform, Pipetting Role and Rack Compatibility

300 µL Sample Tip vs 1300 µL Reagent Tip

The two DYNEX-compatible tip families perform different functions and must not share copied specifications. The 300 µL format is the sample tip; the 1300 µL format is the reagent tip. Select the tip according to the programmed pipetting role, not only by visual shape or maximum capacity.

Quality and Configuration Control

• Controlled upper-cone molding supports repeatable sealing on the instrument pipette adapter.
• Uniform shaft straightness, tip length and distal orifice geometry help maintain aspiration height, dispense position and residual-volume consistency.
• The blue colorant, polypropylene resin and supplied quality status should remain consistent for the confirmed item; any purity claim must be supported by the applicable documentation.
• Packaging integrity, lot identification, material information, dimensional drawings and available quality documents can be supplied for the confirmed ordering configuration.
• Sterility, purity, shelf-life and packaging claims apply only when listed on the current quotation, specification and lot documentation.

Typical Applications

• Automated ELISA sample transfer
• Standards and controls dispensing
• Sample dilution and replication
• Clinical, reference, research and biopharma immunoassay workflows
• High-throughput plate processing after instrument and assay qualification

Recommended Qualification Workflow

1. Identify the instrument: confirm DS2, DS2 Elite or DSX and record the software/method version.
2. Identify the programmed role: sample-tip and reagent-tip positions require different capacities and geometries.
3. Confirm the physical configuration: review tip color, carrier or tray, number of positions, pickup height and packaging.
4. Run mechanical checks: evaluate pickup, sealing, tip detection if applicable, deck clearance and clean ejection across representative positions.
5. Run liquid checks: test minimum, typical and maximum method volumes with representative samples or reagents.
6. Lock the qualified item: record the final item code, lot documentation and method settings before recurring procurement.

Ordering Information

For an accurate quotation, provide the exact DYNEX model, 300 µL sample-tip requirement, 108-position container configuration, required sterility/purity status, requested documents, carton quantity and annual demand. Puretest supports evaluation samples, recurring bulk supply, distributor programs and OEM/private-label projects for confirmed configurations.

Frequently Asked Questions

Is the 300 µL tip a sample tip or a reagent tip?

It is the sample-tip family. The separate 1300 µL format is used for reagent pipetting.

What volume range should I qualify?

Use approximately 10–300 µL as the initial guide and test the actual minimum, typical and maximum method volumes.

How many tips are in the sample-tip container?

The standard sample-tip layout is 108 positions. Confirm the supplied container and packaging on the quotation.

Can these tips be used on DS2 and DSX?

They are designed for compatible DS2/DS2 Elite and DSX sample-pipetting positions, subject to exact-system qualification.

Are these original DYNEX tips?

No. They are independent compatible consumables; validate them on the exact instrument and assay before routine use.
