Analytical Balance

Aczet Precision Weighing Balance for Laboratory Use — Supplied Across India

The Aczet CY Series — 0.1mg readability, motorised internal calibration, ISO / GLP / GMP & USP compliant. Trusted by pharmaceutical, research and quality control laboratories.

What Is a Laboratory Analytical Balance and When Do You Need One?

A laboratory analytical balance is a high-precision weighing instrument designed to measure mass to the fourth decimal place typically 0.1mg (0.0001g) readability. Unlike a standard laboratory balance scale or a top-pan precision balance, an analytical balance operates inside a fully enclosed draft shield that eliminates the effect of air currents, vibration, and ambient temperature variation on your measurement. The result is consistent, repeatable accuracy that meets the requirements of ISO, GLP, GMP, and USP Chapter 41 the regulatory frameworks governing most pharmaceutical and research laboratories in India.

14 weighing units (g, mg, ct, oz, dwt, tola + 8 more)	One instrument covers your analytical lab, jewellery QC desk, and export documentation requirements. No unit conversion errors, no switching instruments.
Application modes: PCS, % Weighing, Density, Formulation, Check Weighing, Statistics	Built-in application software replaces the need for manual calculations. Particularly valuable for check weighing in tablet QC and formulation in R&D compounding.
Capacity bar (overload indicator in display)	Prevents accidental overloading — the single most common cause of balance damage in high-throughput labs. Visual warning before the sample weight exceeds safe capacity.
ISO / GLP / GMP / USP compliance (built-in clock)	Date and time stamp on every weighing record. Meets USP <41> requirements for pharmaceutical balance qualification. Supports SOP documentation and regulatory inspection readiness.
Operating temp 18°C to 30°C, sensitivity drift ±2ppm/°C	Specified for Indian laboratory conditions — standard air-conditioned lab environments. The low drift coefficient (2ppm/°C) means a 1°C temperature change causes less than 0.02mg shift at 220g capacity.

Which Laboratories Use an Analytical Balance and For What?

Pharmaceutical Manufacturing & QC

In pharmaceutical laboratories, an analytical balance is a critical instrument for Active Pharmaceutical Ingredient (API) weighing, excipient measurement, reference standard preparation, and dissolution testing sample preparation. USP Chapter 41 sets minimum weight requirements based on balance readability the Aczet CY series’ 0.1mg readability and 160mg USP minimum weight make it directly compliant for most solid-dose and API weighing tasks at standard capacity. The built-in GLP clock, RS232C data output, and PSAC internal calibration of the CY-C series support the audit trail requirements of Schedule M, WHO-GMP, and US FDA inspection readiness. The CY-F series is additionally available for solvent handling areas classified as explosive zones.

Chemical & Analytical Research Laboratories

Chemical laboratories rely on a precision digital balance for gravimetric analysis, reagent preparation, sample weighing before and after reaction, and preparation of standard solutions. The 0.1mg readability of the Aczet CY series four decimal places in grams is the standard requirement for analytical-grade work as defined by most pharmacopoeias and analytical chemistry protocols. The large draft shield chamber and stable Mono-Tech sensor make the CY series particularly well-suited to weighing hygroscopic compounds and fine powders where airflow and humidity variation cause measurement drift on cheaper balances. Data output to PC via RS232C or USB ensures that weighing records integrate directly into laboratory notebooks and analysis software.

Food Testing & Quality Control

Food testing laboratories use analytical balances for nutritional label verification, ingredient standardisation, moisture content pre-weighing (before halogen moisture analyser analysis), contamination testing, and net weight compliance. The Aczet CY series’ 14-unit capability and check-weighing application mode allow QC technicians to perform routine net weight checks and out-of-tolerance flagging without manual calculation. For food labs requiring moisture content determination, the Aczet MB series halogen moisture analyser (also available through Lab Chemicals) works in direct combination with the analytical balance for complete sample characterisation workflows.

Academic, R&D & Educational Institutions

University chemistry departments, national research institutes, and pharmaceutical R&D facilities require analytical balances that deliver reliable performance across multiple users and experiment types. The Aczet CY standard series (external calibration) is a practical and cost-effective choice for academic laboratories where a dedicated calibration weight set is already part of the lab’s metrology kit. The alpha-numeric display and simple three-button interface make the CY series accessible to student users without sacrificing the measurement accuracy that research-grade experiments demand. The statistics application mode allows direct computation of mean, standard deviation, and RSD for replicate weighings reducing manual data processing in student practicals and research protocols.

Industrial Weighing Precision & Heavy Capacity

For industrial laboratories and production environments requiring weighing beyond the analytical range, the Aczet CY Industrial Precision series (CY 15001H to CY 50000H) handles capacities from 15kg to 50kg with 0.1g readability same Mono-Tech sensor, same ISO/GLP/GMP/USP compliance, larger stainless-steel pan (370 x 260mm) for bulk containers. Internal motorised calibration with PSAC ensures that high-capacity production balances maintain accuracy through temperature fluctuation in non-climate-controlled warehouse and factory environments.

Calibrating Your Analytical Balance How, How Often, and Why It Matters?

Calibration frequency depends on your regulatory environment and application. Pharmaceutical QC and GMP-certified laboratories typically calibrate at the start of every shift or at minimum once daily this is a requirement under most internal SOPs and is expected during WHO-GMP and Schedule M inspections. General research and academic laboratories calibrate at the beginning of each working day or after any balance relocation. The balance must always be recalibrated after being moved to a new location levelling and gravitational field variation both affect reading accuracy. For the Aczet CY-C series, PSAC handles most intra-day calibration automatically; daily manual verification against a certified test weight is still recommended for regulated environments as a formal calibration record.

USP <41> requires that a balance used for pharmaceutical weighing must weigh within 0.10% of the true value, and that the minimum quantity to be weighed is at least 1000 times the smallest increment the balance can read. For the Aczet CY series with 0.1mg readability, this means the minimum weighable quantity for USP compliance is 160mg which is the USP Minimum Weight shown in the Aczet spec sheet and matches the CY series’ published USP minimum weight. Any sample below 160mg on a 0.1mg balance falls outside the USP-compliant weighing range and should be either sub-divided or weighed on a microbalance. Lab Chemicals also supplies Aczet CM Series microbalances for applications requiring sub-100mg weighing with 1µg readability.

FAQs

An analytical balance measures mass to 0.1mg (four decimal places in grams) and operates inside a fully enclosed draft shield to eliminate airflow interference. A precision balance has lower readability (typically 0.01g) and an open pan, making it suitable for larger sample quantities where sub-milligram accuracy is not required. For pharmaceutical API weighing, reference standard preparation, and analytical chemistry an analytical balance is specified. For general reagent preparation and formulation batches in the 300g–600g range, a precision balance is sufficient.

Readability is the smallest increment a balance can display. A 0.1mg readability means the balance displays weight to four decimal places in grams for example, 1.2345 g. This does not mean the balance is accurate to 0.1mg in all conditions; accuracy also depends on repeatability, linearity, and calibration status. The Aczet CY series achieves 0.1mg repeatability (standard deviation) on models up to 220g capacity, which means repeated weighings of the same sample will typically agree within 0.1mg.

Mono-Tech is Aczet’s proprietary single-component weigh sensor technology the heart of the CY series analytical balance. It integrates the weighing cell and sensor into one unit, eliminating mechanical joints and reducing the thermal drift and mechanical slack common in multi-component conventional designs. The result is faster stabilisation (2–3 seconds), better long-term stability, and improved performance in environments subject to minor vibration or temperature variation. All Aczet CY, CY-C, and CY-A analytical balances use Mono-Tech sensor technology.

In pharmaceutical and GMP-regulated environments: calibrate at the start of each working shift, and document the calibration with the date, time, and result in your balance logbook. In general research and academic labs: calibrate at the beginning of each working day. Always recalibrate after moving the balance to a new location. The Aczet CY-C series with Perfect Self Auto Calibration (PSAC) automatically triggers internal calibration when ambient temperature changes beyond a set threshold reducing the manual calibration burden while maintaining a continuous calibration record.

Yes. All Aczet CY series analytical balances carry ISO, GLP, GMP, and USP compliance. The built-in real-time clock enables date- and time-stamped weighing records, which is a core GLP requirement. The published USP Minimum Weight (160mg for all CY series models) confirms compliance with USP Chapter 41 test requirements. For GMP-regulated pharmaceutical manufacturing, the CY-C series’ motorised internal calibration and PSAC function provide the continuous calibration traceability that Schedule M and WHO-GMP inspectors expect.
