Delmer LD 5 Microbalance – 5 g Capacity, 1 µg Readability
The Delmer LD 5 is a laboratory microbalance listed with a 5 g maximum capacity and 1 µg (0.001 mg) readability. It provides a higher listed capacity than the LD 2 while retaining a 1 µg display increment. The listed repeatability is ±2 µg, linearity is ±3 µg and pan diameter is 15 mm.

- Filter or residue weighing where the method and demonstrated performance support the required measurement
- Pharmaceutical research and quality-control workflows, subject to site qualification and procedure requirements
How to assess suitability
Choose a microbalance by comparing the sample mass range, allowable measurement error, repeatability, linearity, uncertainty and minimum usable sample mass. Readability alone does not establish accuracy. Use a stable, level, low-vibration bench and control drafts, static and temperature changes. Follow the manufacturer's operating and calibration instructions.
A product listing does not establish USP, GMP, GLP or legal-metrology certification. For regulated laboratory use, verify documentation and complete the qualification and calibration activities required by the applicable quality system. Commercial precious-metal transactions may have separate local legal-metrology requirements.
LD 5 or LD 2?
The LD 5 is listed for up to 5 g with ±2 µg repeatability, while the LD 2 is listed for up to 2 g with ±1 µg repeatability. Both list 1 µg readability. Match the instrument to the actual sample range and method tolerance; a larger capacity does not automatically mean better measurement performance for every sample.
Frequently asked questions
What does 1 µg readability mean? The display increments in 1 µg steps. It does not by itself guarantee 1 µg accuracy or uncertainty.
Is the LD 5 suitable for GMP work? Suitability depends on verified performance, the procedure, instrument qualification, calibration and site documentation. Confirm requirements before use; the product listing is not a compliance certificate.
What should I provide for model selection? Share the smallest and largest sample mass, required tolerance, application, destination country, documentation needs and data-interface requirements.
