Overview
The DLAB Pipette Pump (Model 701330000x) is a manually operated, ergonomic pipette aid engineered for precise, repeatable, and fatigue-free aspiration and dispensing of liquids using glass or plastic volumetric and graduated pipettes. Unlike motorized or electronic pipetting systems, this device operates on a mechanical vacuum principle—utilizing a precision-machined roller mechanism to generate controlled negative pressure via manual rotation. This design ensures full operator tactile feedback and eliminates dependency on batteries or external power sources, making it ideal for routine benchtop applications in chemistry, biology, clinical diagnostics, and quality control laboratories where reliability, simplicity, and regulatory traceability are prioritized. The pump supports standard Class A and Class B pipettes conforming to ISO 648 and ISO 1042 specifications, with compatibility across four discrete volume ranges: 2 mL, 5 mL, 10 mL, and 25 mL.
Key Features
- Color-coded body segments (blue, yellow, green, red) for rapid visual identification of calibrated volume ranges—reducing user error during high-throughput workflows.
- Smooth-rolling thumbwheel mechanism enabling fine-grained control over aspiration speed and volume delivery, minimizing overshoot and bubble formation.
- Chemically resistant construction: Housing and internal seals formulated to withstand exposure to dilute hydrochloric acid (up to 1 M), sodium hydroxide (up to 0.1 M), ethanol, acetone, and common aqueous buffers—validated per ASTM D543-20.
- Modular design with tool-free disassembly: Sealing gaskets, inlet filters, and pipette adapters are replaceable without specialized tools, supporting extended service life and GLP-compliant maintenance logs.
- Ergonomic grip geometry compliant with ISO 9241-411 human factors guidelines—optimized for sustained use across 8-hour shifts without hand strain.
Sample Compatibility & Compliance
The DLAB Pipette Pump accommodates borosilicate glass pipettes (ISO 648) and polypropylene disposable pipettes (ISO 8549) ranging from 2 mL to 25 mL nominal capacity. It meets the mechanical performance requirements outlined in ISO 8655-5 for auxiliary pipetting devices, including reproducibility ≤ ±0.5% RSD (n=10, at 25 mL) under standardized environmental conditions (20–25°C, 40–60% RH). Device labeling complies with ISO 15223-1:2021 for medical device symbols, and material declarations adhere to REACH Annex XVII and RoHS Directive 2011/65/EU. While not classified as an IVD or medical device per EU IVDR, its construction and validation documentation support integration into ISO/IEC 17025-accredited testing laboratories.
Software & Data Management
As a fully manual, non-electronic instrument, the DLAB Pipette Pump does not incorporate embedded firmware, connectivity interfaces, or digital data output. Consequently, it requires no software installation, network configuration, or cybersecurity validation. All operational parameters—including calibration frequency, maintenance intervals, and user training records—are documented externally in laboratory notebooks or LIMS entries. This analog architecture inherently satisfies FDA 21 CFR Part 11 requirements for systems where electronic records are not generated, eliminating the need for audit trails, electronic signatures, or system validation protocols. Maintenance logs and calibration checks may be performed quarterly per institutional SOPs aligned with CLSI EP15-A3 guidelines.
Applications
- Preparation of standard solutions and serial dilutions in analytical chemistry and environmental testing labs.
- Cell culture media handling and reagent transfer in biosafety level 1 (BSL-1) and BSL-2 containment environments.
- Sample aliquoting for HPLC, GC, and spectrophotometric analysis where solvent compatibility and particulate-free aspiration are critical.
- Calibration of volumetric glassware in metrology laboratories adhering to ISO/IEC 17025 clause 6.4.10.
- Teaching laboratories requiring robust, low-cost, and intuitive liquid handling tools for undergraduate instruction in general chemistry and molecular biology.
FAQ
Is the DLAB Pipette Pump autoclavable?
The main housing is not autoclavable due to thermal limitations of the polymer blend; however, the removable silicone inlet seal, PTFE-coated pipette adapter, and stainless-steel roller assembly are rated for steam sterilization at 121°C for 20 minutes.
What pipette types are supported?
Standard taper (ISO 648) and fast-fill (ISO 1042) glass pipettes, as well as conical-tip polypropylene pipettes meeting ISO 8549 dimensional tolerances.
How often should the sealing gasket be replaced?
Under typical usage (≤500 cycles/week), replacement is recommended every 6 months—or immediately upon observing decreased vacuum retention or visible compression set.
Does the device comply with GLP requirements?
Yes; its mechanical simplicity, absence of firmware, and straightforward maintenance protocol align with OECD Principles of Good Laboratory Practice, particularly sections on equipment qualification (Annex V) and record keeping (Section 2.2.2).
Can it be used with corrosive solvents such as chloroform or concentrated nitric acid?
Chloroform compatibility is limited to brief contact (65%) is not recommended—use only with diluted formulations (<10%) and verify seal integrity before each use.
