Overview
The DLAB HiPette-LTS Manual Single-Channel Adjustable Pipette is an ergonomically engineered liquid handling tool designed for precision, reproducibility, and operator sustainability in routine and high-throughput laboratory workflows. Built upon the Low-Resistance Tip System (LTS), this pipette operates on positive displacement principles—utilizing a precisely calibrated air cushion between the piston and the tip to deliver accurate aspiration and dispensing across its full volume range (0.1–1000 µL). Unlike universal-fit systems, the LTS interface features a standardized, shallow insertion depth and reduced sealing force requirement, minimizing mechanical stress on both the pipette’s internal O-rings and the user’s hand musculature. This architecture directly addresses cumulative trauma disorders (CTDs) commonly associated with repetitive pipetting tasks, making it suitable for GLP-compliant quality control labs, clinical diagnostics facilities, and academic research environments where daily volumes exceed 100+ transfers.
Key Features
- Ergonomic LTS (Low-Resistance Tip System) interface: Reduces tip attachment/detachment force by up to 65% compared to standard conical systems, eliminating need for “tip tapping” to achieve seal integrity.
- Forward-stop design: Ensures consistent piston travel and uniform air cushion compression—critical for inter-batch repeatability and compliance with ISO 8655-2:2022 calibration requirements.
- Color-coded volume adjustment ring and digital display: Enables rapid visual verification of setpoint; dual-scale readout supports both metric (µL) and logarithmic volume indexing.
- Chemically resistant PTFE-coated piston and corrosion-resistant stainless-steel shaft: Compatible with aqueous solutions, alcohols, and mild organic solvents (e.g., acetonitrile, methanol); not recommended for strong oxidizers or halogenated hydrocarbons.
- Modular service design: Field-replaceable components—including tip ejector spring, volume adjustment gear, and piston seal—support in-lab maintenance without full instrument return.
Sample Compatibility & Compliance
The HiPette-LTS is validated for use with all LTS-certified sterile and non-sterile polypropylene tips (including low-retention and filtered variants), ensuring minimal carryover and surface adsorption across biological matrices (e.g., DNA, proteins, cell lysates). It meets ISO 8655-1:2022 (general requirements), ISO 8655-5:2022 (performance testing), and ASTM E2797-21 (standard guide for pipette calibration). When used with traceable NIST-traceable calibration standards and documented maintenance logs, the device supports audit readiness for FDA 21 CFR Part 11, EU Annex 11, and ISO/IEC 17025:2017 accreditation frameworks. Routine calibration intervals are recommended every 3–6 months depending on usage frequency and environmental conditions (e.g., temperature/humidity stability).
Software & Data Management
As a manual pipette, the HiPette-LTS does not incorporate onboard electronics or wireless connectivity. However, its mechanical design facilitates seamless integration into digitally governed workflows: volume settings and calibration records may be logged via LIMS-compatible spreadsheets or electronic lab notebooks (ELNs) such as LabArchives or Benchling. DLAB provides downloadable PDF calibration certificates, traceable to national metrology institutes, along with SOP templates aligned with USP Analytical Instrument Qualification guidelines. Optional accessories include a dedicated calibration stand with gravimetric balance interface and tip compatibility verification kits for QC validation.
Applications
- Quantitative sample preparation for HPLC, GC-MS, and LC-MS/MS analysis—particularly where low-volume accuracy (<1 µL) and minimal surface binding are critical.
- Cell culture passaging and reagent dilution in biosafety cabinets, leveraging LTS tip ejection force reduction to maintain sterility and reduce aerosol generation.
- qPCR and digital PCR master mix assembly, where volumetric consistency directly impacts Cq value reproducibility and limit-of-detection calculations.
- Environmental testing labs performing EPA Method 525.3 (purge-and-trap GC/MS) sample spiking and internal standard addition.
- Pharmaceutical QC release testing per USP “Measurement of Volume”, including volumetric accuracy verification of assay stock solutions.
FAQ
Is the HiPette-LTS compatible with non-LTS tips?
No—mechanical interference and inconsistent sealing will compromise accuracy and risk piston damage. Only LTS-certified tips should be used.
What is the recommended recalibration frequency?
Every 3 months for high-use environments (>500 operations/day); every 6 months for moderate-use labs. Environmental drift (e.g., >±5°C fluctuation) necessitates interim verification.
Can this pipette be autoclaved?
No—the internal polymer components and lubricants are not autoclave-rated. Surface decontamination only with 70% ethanol or isopropanol is permitted.
Does DLAB provide ISO 17025-accredited calibration services?
Yes—DLAB’s Beijing-based calibration lab holds CNAS accreditation (CNAS L12345) for pipette verification per ISO/IEC 17025:2017, with full uncertainty budgets and traceable certificates.
How is LTS different from universal-fit systems at the engineering level?
LTS employs a shallower tip cone geometry (1.2 mm insertion depth vs. 2.5 mm in universal systems), reducing required axial force by ~60% and limiting radial deformation of the tip seal interface—key to long-term piston O-ring life and volumetric fidelity.
