Question 1

What is YEK-BALANCE analytical balance and what precision does it have?

Accepted Answer

YEK-BALANCE is a laboratory analytical balance with 0.1 mg (0.0001 g) readability precision. It measures at microgram level with 150-gram maximum weighing capacity. EMF (Electromagnetic Force Restoration) sensor technology provides long-life use without mechanical wear. ±0.1 mg repeatability and ±0.2 mg linearity guarantee consistent results in successive measurements. Critical equipment for chemical analysis, drug formulation, reference standard preparation, HPLC/GC sample preparation, gravimetric analysis, and pipette calibration. Appropriate documentation provided for use in ISO/IEC 17025 accredited laboratories.

Question 2

What are the technical specifications and measurement performance of analytical balance?

Accepted Answer

YEK-BALANCE technical specifications: capacity 150 g, readability 0.0001 g (0.1 mg), repeatability (standard deviation) ≤0.1 mg, linearity ±0.2 mg (0-150 g range), calibration external (with E2 class weight), stabilization time 3-8 seconds (depending on ambient conditions), weighing units: g, mg, carat, oz, lb, pieces, percent. Weighing pan Ø80 mm stainless steel, glass draft shield (3-sided opening), 120x40 mm LCD display (backlit), operating temperature 10-30°C, humidity tolerance max 80% RH (non-condensing). Weight: 5.2 kg, dimensions: 210x330x320 mm (WxDxH).

Question 3

Why is analytical balance used with glass draft shield?

Accepted Answer

Weighing at 0.1 mg precision is extremely sensitive to air currents. Even slight air movement can affect measurement result. YEK-BALANCE's glass draft shield isolates weighing pan from external air currents, laboratory air conditioning, breathing airflow, and door/window drafts. Glass panels that can be opened from three sides facilitate sample placement. Antistatic glass material protects against electrostatic charge accumulation (especially critical for plastic and powder samples). Transparent glass provides clear view during weighing. Not reading value before balance shows stable (⚖️ symbol) is mandatory for reliable results.

Question 4

How is analytical balance calibrated and how often should calibration be performed?

Accepted Answer

YEK-BALANCE uses external calibration system. Calibration procedure: (1) Balance should be ready after 30-minute warm-up period. (2) CAL function selected from calibration menu. (3) E2 class calibration weight (e.g., 100 g or 200 g certified weight) placed on weighing pan. (4) Balance automatically calibrates and gives confirmation message. Calibration frequency: after initial setup, when balance location is changed, when environmental conditions change (temperature/humidity), monthly routine calibration, weekly in intensive use. In accredited laboratories (ISO/IEC 17025), calibration records must be kept and traceability to national standards ensured.

Question 5

What factors should be considered for accurate measurement with analytical balance?

Accepted Answer

Critical factors for accurate measurement: (1) Balance location: away from vibration (ground floor preferred), protected from direct sunlight, no air currents (away from air conditioning and fume hood outlets), away from electromagnetic fields (microwave, strong magnets). (2) Level adjustment: balance level indicator (bubble level) must be centered. (3) Warm-up time: at least 30 minutes, preferably kept on 1 hour before. (4) Sample temperature: must match room temperature (hot samples create thermal air currents). (5) Electrostatic charge: plastic and powder samples should be neutralized with antistatic rod. (6) Glass shield: must be closed during each weighing. (7) Cleanliness: weighing pan and surroundings should be regularly cleaned, no dust accumulation.

Question 6

Which standards does analytical balance comply with and are certificates required?

Accepted Answer

YEK-BALANCE complies with international weighing standards and quality regulations: USP (United States Pharmacopeia) - pharmaceutical industry measuring equipment, EN 45501 (optional) - non-automatic weighing instruments, OIML R76 - non-automatic weighing instruments metrology standard, ISO 9001 - manufacturer quality management system, GLP/GMP - Good Laboratory/Manufacturing Practices documentation requirements, CE, FCC, RoHS - electrical safety and environmental compliance. Calibration certificate: for accredited laboratories, calibration certificate traceable to national metrology institute (in Turkey, UME - National Metrology Institute) can be provided (optional, extra fee). Factory calibration certificate provided as standard.
