MATRIX IMPACT 2 5-250µL 8-CHANNEL ADJUSTABLE ELECTRONIC PIPETTE

Product Overview This Matrix Impact 2 (Thermo Scientific) electronic multichannel pipette is a reliable laboratory instrument designed for precise, high-efficiency liquid handling. The unit features 8 channels with a volume range of 5-250 µL and manual tip spacing adjustment via Equalizer technology. It has been tested and powers up as expected. The internal battery requires replacement, calibration is needed prior to accurate use, and no power adapter is included.

Intended Applications Ideal for professional laboratory environments requiring consistent multi-sample dispensing, including:

• High-throughput screening and sample preparation in 96-well microplates
• PCR and qPCR setup
• ELISA and other immunoassay protocols
• Cell culture media transfer and dilutions
• Serial dilutions, supernatant collection, and incremental pipetting
• Gel loading with controlled slow dispensing for viscous liquids

The adjustable tip spacing enhances versatility when working between different labware formats.

Technical and Functional Specifications

• Volume Range: 5.0–250.0 µL per channel
• Channels: 8
• Tip Spacing: Manually adjustable from 9 mm to 14 mm (some may have the side scale indictors, while other may not have this, but both have space tips operated in a manual fashion)
• Accuracy (manufacturer specification at full volume): ±2.0% or 1.5 µL
• Precision (manufacturer specification at full volume): ±0.7% or 1.0 µL
• Operation: Fully electronic with step-based programming (up to 5 stored programs, each with up to 40 steps)
• Pipetting Modes: Standard pipette, repeat dispense, mix (2–9 cycles), purge, incremental pipetting, serial dilutions, and supernatant collection
• Speed Control: 5 independent settings (slow to fast) for aspiration, dispensing, mixing, and purge; enhanced control for viscous liquids
• Additional Features: Ergonomic lightweight design to minimize repetitive strain injury, automatic blowout, paced dispense, Easy CAL mode for in-lab calibration verification, and audible tone options
• Power Requirements: Rechargeable internal battery (replacement required); operates on 2.5 VDC 400 mA regulated adapter with connector resembling a headphone jack; original Matrix catalog number for the adapter is 6098

Condition The pipette has been fully tested and powers on successfully. It will require calibration by a qualified technician before use in precision applications. The battery must be replaced, and no power adapter is supplied. This unit is sold in its current tested condition for laboratory professionals or service personnel.
