1300 µL Reagent Pipette Tips Compatible with Dynex DS2 and DSX

Puretest 1300 µL reagent pipette tips are designed as an independent compatible consumable for reagent transfer on DYNEX DS2, DS2 Elite and DSX automated ELISA systems. The clear large-capacity tip supports the instrument reagent-pipetting workflow while allowing direct visual inspection of the liquid column.

The 1300 µL designation describes the tip capacity; the instrument reagent-pipetting range is approximately 20–1000 µL. This distinction matters for method setup and prevents the incorrect assumption that the full physical tip capacity is the recommended dispense range. The 1300 µL reagent tip is separate from the blue 300 µL sample-tip family.

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 reagent-tip specification: 1300 µL nominal capacity for approximately 20–1000 µL reagent transfers.
• Clear large-volume fluid path: supports visual inspection of aspiration, dispense and residual liquid.
• Dedicated reagent role: intended for DYNEX reagent-pipetting positions, not sample-tip positions.
• DS2/DSX workflow target: for compatible DYNEX DS2, DS2 Elite and DSX systems.
• Controlled disposable geometry: consistent upper collar, long shaft and distal orifice for automated handling.
• Supply support: samples, technical drawings and available quality documents for qualification.

Tip Structure and Functional Design

The 1300 µL reagent tip uses a ribbed upper collar and long clear tapered shaft. The cone must seal consistently on the reagent-pipetting adapter while the shaft provides reach into reagent bottles, tubes or intermediate vessels. Sufficient internal capacity above the 1000 µL method maximum provides the geometry required by the instrument-specific format.

Reagent methods may involve larger volumes, repeated dispensing and liquids with different viscosities or surfactant content. Qualification should include full-volume aspiration, multi-dispense steps if used, residual-volume checks, reagent-vessel clearance and clean tip ejection. The exact carrier or supply tray must also be confirmed because instrument deck capacity is not the same as commercial packaging quantity.

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.
• Clear polypropylene resin, collar dimensions, shaft straightness and orifice consistency should be controlled for the confirmed item; any purity or sterilization claim requires current supporting 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 reagent transfer
• Wash-independent reagent and conjugate dispensing
• Substrate, diluent and buffer handling
• Repeated reagent dispense steps after validation
• Clinical, reference, research and biopharma immunoassay automation

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, 1300 µL reagent-tip requirement, instrument carrier or tray details, required sterility/purity status, requested documents, package quantity and annual demand. Puretest supports evaluation samples, recurring bulk supply, distributor programs and OEM/private-label projects for confirmed configurations.

Frequently Asked Questions

Why is the tip called 1300 µL if the method range is 20–1000 µL?

1300 µL is the nominal physical tip capacity; approximately 20–1000 µL is the reagent-pipetting range used for instrument selection and method qualification.

Is this the same as the 300 µL blue tip?

No. The 1300 µL clear tip is the reagent-tip family, while the 300 µL blue tip is used for sample pipetting.

How many reagent tips fit in the instrument?

Official system information lists 20 reagent-tip positions for DS2/DS2 Elite and 41 for DSX. Commercial packaging must be confirmed separately.

Can these tips be used for repeated dispensing?

Potentially, when the instrument method supports it; validate reagent properties, total aspirated volume, residual volume and dispense consistency.

Are these original DYNEX consumables?

No. They are independent compatible tips and require exact-system and assay qualification.
