Adam Luna Series 0.1g Readability High-Capacity Precision Balance

Overview

The Adam Luna Series LBB high-capacity precision balance is engineered for rigorous laboratory and industrial environments where reproducible mass measurement at 0.1 g readability is required across extended weighing ranges—up to 15,000 g. Built upon Adam Equipment’s legacy of ISO 9001-certified manufacturing in the UK, the Luna LBB implements electromagnetic force restoration (EMFR) transduction technology optimized for stability under variable environmental conditions. Its design prioritizes metrological integrity: integrated leveling indicators and adjustable feet ensure mechanical alignment within ±0.5°, a prerequisite for traceable mass determination per ISO/IEC 17025 and OIML R 76 guidelines. The balance operates without internal calibration mechanisms, relying exclusively on external weight-based calibration—a configuration aligned with GLP and GMP workflows requiring documented, auditable calibration events using certified reference masses.

Key Features

• Backlit LCD display with 24 mm high white numerals on a high-contrast black background ensures legibility under ambient lighting or low-illumination lab conditions.
• Color-coded tactile keys accelerate operator workflow by enabling rapid identification of frequently used functions including unit toggle, tare, and print initiation.
• Integrated spirit level and dual-height adjustable leveling feet facilitate precise horizontal alignment—critical for minimizing gravitational vector error in high-precision applications.
• 304 stainless steel weighing pan (185 × 185 mm) resists corrosion from solvents, acids, and particulate abrasion; seamless welds and smooth edges prevent residue entrapment.
• Sealed membrane keypad prevents ingress of dust, powders, and liquid splashes—meeting IP42-rated protection for routine laboratory use.
• RS-232 and USB-B interfaces support bidirectional communication with PCs, label printers, and LIMS systems; ASCII-compatible output enables direct integration into Excel, LabWare, or custom data acquisition platforms.
• External calibration capability using Class M2 or better weights complies with ISO 17025 Clause 6.5 and supports full audit trails for regulatory submissions.
• Digital filtering algorithms mitigate vibration-induced noise during dynamic weighing (e.g., animal or conveyor-belt applications), configurable via front-panel menu.
• Auto-off timer (adjustable: 5–60 min) conserves power without compromising startup readiness; includes AC adapter for continuous operation.

Sample Compatibility & Compliance

The Luna LBB accommodates heterogeneous sample forms—including bulk solids, packaged components, wet specimens, and irregularly shaped objects—without degradation in repeatability. Its 200 g minimum weight threshold (per USP <41> and EUR Pharm 2.2.17) ensures compliance with pharmacopeial requirements for quantitative assay preparation. All models are CE-marked, compliant with EMC Directive 2014/30/EU and Low Voltage Directive 2014/35/EU. Firmware supports audit-trail-enabled operations per FDA 21 CFR Part 11 when paired with validated software, and built-in time/date stamping on printed outputs satisfies GLP documentation standards.

Software & Data Management

Data export follows NIST-traceable ASCII protocols: each record includes timestamp, net/gross/tare values, unit identifier, and operator ID (if configured). USB interface enables mass storage mode for firmware updates and configuration backup. Optional Adam DU software provides real-time graphing, statistical analysis (mean, SD, CV%), and automated report generation in PDF or CSV formats—validated for use in ISO 13485 medical device manufacturing environments. All communication logs retain immutable timestamps for retrospective review during internal audits.

Applications

• Quality control laboratories performing raw material verification, batch release testing, and formulation checks where 0.1 g resolution meets acceptance criteria per ASTM E122 and ISO 2854.
• Pharmaceutical production units conducting excipient dispensing, tablet weight checks, and capsule filling validation per USP <905>.
• Food processing facilities executing portion control, ingredient batching, and shelf-life study sample preparation.
• Educational institutions requiring robust, serviceable balances for undergraduate analytical chemistry and materials science curricula.
• Recycling and scrap metal sorting operations requiring high-throughput weighing with resistance to mechanical shock and thermal drift.

FAQ

What calibration weights are recommended for the LBB series?
Class M2 or higher certified weights traceable to national standards (e.g., NIST, UKAS) are required for external calibration. Calibration must be performed at ≥20% and ≥100% of maximum capacity per ISO 17025 Clause 6.5.3.
Does the Luna LBB support GLP-compliant data printing?
Yes—date/time stamps, operator ID fields (via optional keypad entry), and unit identifiers are embedded in all RS-232 and USB print outputs, satisfying GLP Annex 11 and 21 CFR Part 11 electronic record requirements when used with validated printers.
Can the balance operate continuously without auto-shutdown?
Yes—the auto-off timer can be disabled via setup menu; continuous operation is supported using the included 18 V DC adapter.
Is the stainless steel pan removable for cleaning?
No—the pan is permanently mounted to the load cell assembly to preserve metrological integrity; cleaning is performed in situ using lint-free cloths and ethanol or isopropanol.
What is the warm-up time before first use?
A 30-minute stabilization period at nominal operating temperature (20–25 °C) is recommended prior to initial calibration or critical measurements, as specified in the user manual per ISO 9001 clause 7.1.5.2.
