Balances — Precision, Reliability, and Performance for Every Application

At American Scale Supply, we provide a wide range of balances and scales designed to meet the highest standards of precision and durability. From analytical scales for laboratory research to top-loading balances for industrial use, our instruments ensure accuracy and consistency in every measurement.

Whether you’re weighing powders, chemicals, or biological samples, our lab balance solutions deliver dependable results — every time. Each model is engineered for smooth operation, long-term reliability, and easy calibration.

Why Choose a Precision Balance?

Modern laboratories and production facilities rely on accurate measurement to maintain product quality and compliance. A small error in weight can translate into significant issues in formulation, testing, or production efficiency.

That’s why our balances offer precision down to 0.1 mg and even 0.01 mg for the most sensitive applications. Whether you’re a research chemist, educator, or quality control technician, precision matters — and our instruments are built to perform.

Types of Balances and Scales We Offer

Our collection includes multiple balance categories designed for different environments and workloads. Each category is backed by robust construction, reliable electronics, and calibration support.

1. Analytical Balances

Analytical scales are essential for laboratories that require ultra-precise measurements of small masses. These analytical balances offer readability as fine as 0.1 mg, providing stability and repeatability for detailed testing and formulation work.

They feature draft shields, vibration protection, and advanced filtering to eliminate errors caused by air currents or static electricity. Ideal for use in pharmaceutical, chemical, and academic research labs.

Typical Applications: Chemical formulation, drug testing, and material analysis.

2. Precision Balances

Precision balances, also called top-loading balances, are used for heavier samples while maintaining fine accuracy. These models typically provide readability from 1 mg to 0.1 g and are perfect for laboratories, educational settings, and industrial production.

Our balances and scales combine speed, stability, and easy-to-read digital displays for efficient operation.

Typical Applications: Sample preparation, quality control, and material batching.

3. Portable and Compact Balances

For fieldwork or mobile laboratory environments, our compact and portable models offer excellent value and convenience. Despite their small footprint, these balances offer dependable accuracy for quick measurements. They are battery-powered, lightweight, and easy to transport.

Typical Applications: Field research, classroom use, or on-site sampling.

4. Moisture Analyzers

Our moisture analyzers determine the moisture content of powders, food, or pharmaceutical products. This is critical for quality control, shelf life assessment, and research.

Equipped with halogen or infrared drying technology, these balances ensure rapid, precise analysis. Combined with a lab balance, they help laboratories maintain consistent product performance and meet industry standards.

Typical Applications: Food analysis, agricultural testing, pharmaceutical development.

5. Accessories and Weighing Papers

To support your precision measurements, we also offer essential accessories like weighing papers, calibration weights, and anti-static covers. Weighing papers help maintain sample purity and prevent contamination — particularly important in chemical or biological analysis.

Tip: Use clean, dry weighing papers with each new sample to maintain integrity and avoid residue transfer.

Choosing the Right Balance for Your Needs

Selecting the ideal lab balance depends on several key factors:

Capacity & Readability – Consider your typical sample size. Analytical balances measure microgram quantities, while precision balances handle larger weights.
Environment – Place your balance on a stable, vibration-free surface. Avoid drafts and temperature fluctuations for consistent results.
Application – A research lab might require a 0.01 mg analytical model, while a classroom or production site could use a more rugged, high-capacity balance.
Compliance – Ensure your balance meets regulatory standards (e.g., NTEP certification if used for commercial weighing).
Maintenance & Calibration – Regular calibration maintains accuracy and ensures reliable operation.

Features Our Balances Offer

Every product in our collection is designed with precision and user experience in mind. Common features include:

High-resolution LCD or touch-screen displays
Tare and auto-calibration functions
Draft shields for ultra-fine weighing
USB or RS232 connectivity for data transfer
Adjustable feet and leveling bubble
Overload protection systems
Quick response times and stability filters

Together, these balances offer a combination of speed, sensitivity, and durability that makes them ideal for laboratory and production environments alike.

Laboratory Applications

Our analytical scales and lab balance instruments support a variety of professional applications:

Pharmaceutical Research: Ensuring accurate formulation and dosage control.
Educational Laboratories: Teaching precision measurement principles.
Chemical Analysis: Measuring reactive substances in controlled conditions.
Food Testing: Evaluating moisture content, additives, and nutritional consistency.
Environmental Studies: Determining trace sample weights for soil, air, or water research.

Each balance is designed to deliver consistent, traceable results that meet the demands of scientific and industrial standards.

Maintenance and Calibration

Routine maintenance and calibration are essential for consistent performance.

Calibration Tips

Use certified calibration weights recommended by the manufacturer.
Allow the balance to warm up before use, especially in temperature-controlled environments.
Calibrate at regular intervals or after moving the balance.

Cleaning and Care

Wipe the surface gently with a soft, lint-free cloth.
Avoid liquids and harsh chemicals.
Store in a clean, dry location to prevent dust accumulation.

With proper care, your lab balance will deliver years of reliable, precise results.

Frequently Asked Questions

Q: What is an analytical balance?
An analytical balance is a laboratory instrument designed to measure small masses with high precision — typically to 0.1 mg or finer. It’s enclosed in a draft shield to prevent external interference.

Q: What’s the difference between a precision and analytical balance?
Analytical balances are used for microgram measurements, while precision balances handle heavier samples with slightly lower resolution.

Q: How do I determine the moisture content of a sample?
Use a moisture analyzer, which gently heats the material and calculates moisture content based on weight loss.

Q: What accessories should I use with my balance?
Always use weighing papers or sample containers to prevent contamination and maintain accuracy.
