What is AS3302?

AS3302 is an automated weighing system that replaces repetitive manual weighing steps in
the laboratory. The system runs configurable weighing methods, records sample weights automatically and
exports structured data for easy review, reporting or integration into laboratory data workflows.

It can be adapted to a wide range of precision weighing applications, particularly in soil testing,
environmental analysis, agriculture, food, mineral laboratories and service laboratories processing large
numbers of samples.

Why Automate Sample Weighing?

Weighing is a fundamental but critical step in many analytical workflows. When sample numbers increase,
manual weighing can introduce errors through operator handling, sample position mix-ups, transcription
mistakes, repeated data entry and variability between shifts or users.

AS3302 standardizes the weighing process by automatically recording data and generating clear CSV output.
This is valuable for laboratories that need consistent batch-based weighing records, improved traceability
and reduced manual data handling.

Key Features of AS3302

• Fully automatic weighing system:
  reduces manual handling and improves consistency in repetitive weighing workflows.
• Capacity for up to 80 samples:
  suitable for laboratories processing sample batches.
• 0.1 mg balance resolution:
  supports precision laboratory weighing applications.
• Controlled weighing environment:
  provides appropriate conditions for precision weighing.
• Automatic data handling:
  records all weights and exports data into an easy-to-understand CSV file.
• Configurable method builder:
  allows the weighing process to be adjusted to match testing requirements.
• Integrated computer and software:
  Windows-based software is included for full control of the weighing process.
• Data workflow support:
  CSV export can support LIMS or internal laboratory data management workflows.

Available AS3302 Models

Typical Applications of AS3302

1. Organic Matter Determination in Soil

AS3302 is particularly suitable for weighing soil samples as part of organic matter determination workflows.
It helps record sample weights automatically by batch, reduces weighing-step errors and provides consistent
input data for subsequent analytical steps.

2. Soil and Agricultural Laboratories

In soil testing centers, sample volumes are often high and weighing is repeated many times each day.
AS3302 helps increase sample processing productivity, reduce technician workload and improve traceability
between samples, trays and recorded weights.

3. Environmental Testing

Environmental laboratories can use AS3302 for weighing solid samples, soils, sludges, filters or other
samples before further analysis. Automated weighing reduces manual data entry errors and improves consistency
between sample batches.

4. Food, Feed and Agricultural Products

AS3302 can support QC and R&D laboratories that need to weigh many food, feed, agricultural or raw material
samples with high precision. CSV output makes it easier to manage weighing records and import data into
internal systems.

5. Minerals and Materials

In mineral and materials analysis, accurate weighing directly affects the quality of analytical results.
AS3302 standardizes sample weighing, reduces operator dependency and supports laboratories with high sample
volumes or strict data handling requirements.

6. General Laboratory Weighing

Beyond specific applications, AS3302 can be adapted to a variety of precision weighing workflows through
its configurable method builder and application-specific weighing adapters.
