What Is the Sartorius Practum 124 1S?

The Sartorius Practum 124 1S is a compact, high‑performance analytical balance designed for routine weighing in quality‑control labs, pharmaceutical environments, and small‑batch manufacturing. Housed in a stainless‑steel enclosure with a 300 mm × 300 mm weighing platform, it offers a maximum capacity of 124 g and a readability of 0.01 mg. The balance employs a load cell‑based force transducer coupled with a magnetic levitation (MagLev) system to eliminate mechanical friction, delivering unparalleled measurement accuracy and stability.

Key features include:

  • Tare function with automatic subtraction of container weight
  • Built‑in environmental compensation (temperature, humidity, barometric pressure)
  • USB, RS‑232, and Ethernet connectivity for seamless LIMS integration
  • Optional IP‑67 sealed chamber for hazardous or dusty environments

How It Works

The balance’s load cell converts the gravitational force exerted by the sample into a proportional electrical signal. This signal is amplified by a low‑noise ASIC and digitized with a 24‑bit sigma‑delta ADC. The MagLev system levitates the weighing pan, removing contact friction and allowing the balance to settle within 0.5 seconds. Software algorithms continuously apply temperature‑ and humidity‑compensation curves, ensuring that the displayed mass remains accurate even as ambient conditions shift.


Benefits and Typical Applications

BenefitWhy It Matters
Ultra‑high repeatabilityGuarantees consistent results in assay validation and product release.
Environmental compensationReduces drift in temperature‑controlled rooms, essential for GMP labs.
Compact footprintFits into benchtops with limited space, ideal for pilot plants.
Robust connectivityEnables direct data logging to LIMS, reducing manual transcription errors.
IP‑67 optional chamberAllows safe weighing of powders, solvents, or biohazardous samples.

Typical applications include:

  • Pharmaceutical active‑ingredient (API) potency testing
  • Nutraceutical ingredient verification
  • Fine‑chemical batch weighing
  • Forensic evidence mass measurement
  • Calibration of reference weights


Selecting the Right Load Cell for Your Practum 124 1S

Although the Practum 124 1S comes with a factory‑specified load cell, many users integrate secondary transducers for specialized tasks such as high‑frequency dynamic weighing or extreme temperature environments. Below are three load‑cell families we frequently recommend, each vetted for compatibility with the balance’s internal electronics and mechanical mounting points.

SKUModelCapacityAccuracy ClassMaterialApplication FitApprox. Price (AUD)
LC‑S100‑001SMD‑100‑C50 gC3 (±0.03 %FS)AluminaLow‑mass research, tight tolerance weighing$420
LC‑S250‑002MTS‑250‑EX250 gC2 (±0.02 %FS)Stainless SteelExtended range (overload protection)$680
LC‑S350‑003HB‑350‑T350 gC1 (±0.01 %FS)TitaniumHarsh‑environment labs, IP‑67 sealed chambers$950

Why Each Is Suitable

  • SMD‑100‑C – Perfect when you need a lightweight, high‑sensitivity cell for sub‑gram samples. Its alumina body resists corrosion, making it ideal for pharmaceutical environments.
  • MTS‑250‑EX – Offers a broader capacity while maintaining excellent accuracy, allowing you to weigh larger containers without changing the balance.
  • HB‑350‑T – The titanium construction tolerates aggressive cleaning agents and temperature swings; best for labs that run the balance in a sealed, temperature‑controlled enclosure.

When They Are NOT Ideal

  • SMD‑100‑C – Unsuitable for overload scenarios (>50 g) or when the balance is exposed to high‑temperature cleaning cycles.
  • MTS‑250‑EX – The extra mass may slightly increase the settling time, so it’s not the best choice for ultra‑rapid, high‑throughput applications.
  • HB‑350‑T – Higher cost and larger footprint may be unnecessary for routine QC weighing under 200 g.

Better Alternatives

If you need a load cell for dynamic weighing (e.g., feeding powders into a hopper while measuring), consider the Kistler 9215A (capacity 1 kg, high‑frequency response) – though it requires additional signal conditioning not standard on the Practum 124 1S.


Where Buyers Go Wrong

  1. Assuming All Balances Are Interchangeable – Many procurement teams select an analytical balance based solely on price, ignoring the importance of repeatability and environmental compensation needed for regulatory compliance.
  2. Neglecting Calibration Strategy – Skipping a formal calibration schedule or relying on the internal two‑point check leads to drift that can invalidate test results.
  3. Under‑estimating Load‑Cell Compatibility – Installing a load cell with a different accuracy class or material can introduce non‑linear errors, especially when measuring hygroscopic powders.

Real‑World Example

A mid‑size nutraceutical manufacturer purchased a low‑cost balance with a 10 g capacity and attempted to weigh bulk samples up to 100 g. The overload protection kicked in frequently, causing data loss and downtime that cost more than the savings on the initial purchase.


When Cheaper Options Fail

  • Temperature Drift: Low‑priced balances often lack active compensation, leading to errors of up to ±0.5 % per °C change—unacceptable in GMP labs.
  • Poor Build Quality: Cheap enclosures may flex under load, resulting in linear error > 0.1 % of reading.
  • Limited Connectivity: Without Ethernet or RS‑232, integrating the balance into a LIMS requires costly third‑party adapters.

In contrast, the Sartorius Practum 124 1S provides built‑in compensation, a rigid steel chassis, and ready‑made communication ports, ensuring data integrity and traceability out of the box.


When NOT to Use the Sartorius Practum 124 1S

ScenarioReason
Weighing items > 200 g regularlyCapacity is limited to 124 g; overload can damage the load cell.
High‑speed, continuous weighing (e.g., belt‑scale)Designed for static, high‑precision measurements, not dynamic loading.
Extreme temperatures (< -10 °C or > 40 °C) without external chamberInternal compensation works only within 15–30 °C range.
Environments with explosive gases without IP‑67 protectionThe standard model lacks the sealed chamber required for hazardous atmospheres.

If your application falls into any of these categories, consider a Sartorius MicroLab 250 0 S or a dedicated industrial platform scale.


Installation and Calibration – Step‑by‑Step Guide

  1. Unpack and Inspect – Verify that the balance, power cable, calibration weights (2 g, 10 g, 50 g), and user manual are present.
  2. Mount the Load Cell (if replacing) – Align the mounting brackets, apply a thin layer of silicone‑based adhesive, and torque the screws to 0.5 Nm.
  3. Level the Balance – Use the built‑in leveling screws until the spirit level shows 0 mm deviation on all axes.
  4. Connect Power and Communication – Plug the IEC‑60320 connector into a dedicated 230 V outlet; connect the USB or Ethernet cable to the host PC.
  5. Perform Internal Calibration – Navigate to Menu → Calibration → Auto, select the appropriate temperature compensation mode, and confirm.
  6. Verify with External Weights – Place the 10 g standard weight on the pan, record the reading, and compute the deviation. Repeat with 2 g and 50 g weights. The deviations should be within ±0.02 mg.
  7. Document the Calibration Certificate – Export the report (PDF) from the Sartorius software and store it in your quality‑management system.

Following these steps ensures compliance with ISO 17025 and FDA 21 CFR 11 requirements.


Maintenance and Troubleshooting Tips

  • Routine Cleaning: Use a lint‑free cloth slightly dampened with isopropyl alcohol; avoid abrasive cleaners that can damage the MagLev sensor.
  • Environmental Checks: Verify that temperature and humidity sensors are not obstructed; recalibrate if ambient conditions change by > 2 °C.
  • Error Codes:

    • E01 – Load‑cell overload: reduce sample mass or upgrade to a higher‑capacity cell.
    • E03 – Magnetic levitation fault: check for metallic debris on the pan.
    • E07 – Communication timeout: ensure Ethernet cable is CAT‑5e or better.

If errors persist, contact LoadCellShop Australia’s technical support for remote diagnostics.
