Rainin Pipet-Lite Manual Multichannel Pipette with LTS Cylindrical Tip Interface

Overview

The Rainin Pipet-Lite Manual Multichannel Pipette is an ergonomically engineered liquid handling instrument designed for high-throughput, precision volumetric transfer in life science, clinical diagnostics, pharmaceutical QC, and academic research laboratories. Built on Rainin’s proprietary Low-Torque Sealing (LTS) cylindrical tip interface architecture, the Pipet-Lite eliminates reliance on O-rings or excessive plunger force to achieve leak-free, repeatable tip attachment and seal integrity. Its mechanical design adheres to ISO 8655–2 (volumetric accuracy and precision requirements) and ISO 8655–6 (performance testing protocols), ensuring traceable metrological performance across all calibrated volume ranges. Unlike legacy universal-fit pipettes, the LTS system guarantees consistent tip engagement geometry—critical for minimizing inter-operator variability and maintaining assay reproducibility in multi-user environments.

Key Features

• LTS Cylindrical Tip Interface: Precision-machined cylindrical sleeve ensures uniform radial compression of LTS-certified tips—no O-rings required, no manual tightening, and zero risk of over-torque-induced tip deformation or leakage.
• LiteTouch™ Tip Ejection (LTSTM): Reduces ejection force by up to 75% compared to conventional systems, minimizing wrist fatigue during repetitive operations and preserving sample integrity during sensitive assays (e.g., qPCR master mix preparation or low-volume cell culture media dispensing).
• One-Step Tip Loading: All multichannel variants (8- and 12-channel) accept full tip racks in ≤2 seconds; alignment is self-guided via tactile feedback and visual indexing marks on the tip ejector bar.
• Ergonomic Balance & Low Activation Force: Center-of-gravity optimized chassis and spring-assisted plunger mechanism reduce hand strain—validated per ISO 10993–5 biocompatibility and EN 614–1 ergonomic assessment guidelines.
• Modular Calibration Support: Fully serviceable design with field-accessible calibration screws; compatible with Rainin’s ProCal™ verification tools and third-party gravimetric calibration workflows per USP and ASTM E2758.

Sample Compatibility & Compliance

The Pipet-Lite supports aqueous, viscous (up to 50% glycerol), and volatile solvents (e.g., ethanol, DMSO) when used with appropriate LTS-certified polypropylene tips. It meets essential regulatory expectations for routine laboratory use under GLP and GMP frameworks: audit trails are supported through optional Rainin LiteTouch™ Log software integration (21 CFR Part 11 compliant when deployed with validated IT infrastructure). All models ship with a Certificate of Conformance referencing ISO 8655–2:2022 and factory calibration data at nominal volumes (10%, 50%, and 100% of range). Traceable calibration services—including uncertainty budgets per ISO/IEC 17025—are available through Rainin Authorized Service Centers.

Software & Data Management

While the Pipet-Lite is a fully manual device requiring no onboard electronics, it integrates seamlessly into digital lab ecosystems via Rainin’s free LiteTouch™ Log desktop application. This tool enables users to record calibration events, operator IDs, environmental conditions (temperature/humidity), and maintenance logs—exportable as PDF or CSV for internal QA review or external audit submission. When paired with Rainin’s XLS series electronic pipettes, the same software platform provides cross-platform data harmonization, facilitating SOP alignment across manual and automated liquid handling workstations.

Applications

• High-density microplate filling for ELISA, cell-based assays, and drug screening
• Serial dilution workflows in molecular biology (DNA/RNA quantification, NGS library prep)
• QC sampling in pharmaceutical manufacturing (raw material testing, stability studies)
• Diagnostic reagent dispensing in CLIA-certified clinical labs
• Teaching laboratories requiring robust, student-proof instrumentation with minimal maintenance overhead

FAQ

Is the Pipet-Lite compatible with non-LTS tips?
No. The LTS cylindrical interface requires Rainin LTS-certified tips to ensure proper sealing, accuracy, and longevity. Universal or non-LTS tips will not seat correctly and may cause volume inaccuracy or tip ejection failure.
What volume ranges are available for 12-channel configurations?
Standard 12-channel models cover 1–10 µL, 2–20 µL, 5–50 µL, 20–200 µL, 20–300 µL, and 100–1200 µL. Fixed-volume variants (e.g., FL12-20) are also available for dedicated high-repetition tasks.
Can the Pipet-Lite be calibrated in-house?
Yes—calibration is performed using standard gravimetric methods per ISO 8655–6. Rainin provides detailed service manuals and offers certified technician training for qualified laboratory personnel.
Does the LTS system affect tip cost or availability?
LTS tips are widely distributed globally and priced competitively with premium universal tips. Their standardized geometry also reduces tip lot-to-lot variability—a key factor in long-term assay robustness.
How does LiteTouch™ reduce operator injury risk?
By lowering tip ejection force to ≤1.2 N (vs. >4.5 N in conventional systems), LTSTM significantly decreases cumulative trauma exposure—particularly relevant in labs operating under EU Directive 2002/44/EC (hand-arm vibration syndrome prevention).
