Q2: What is the price and local procurement procedure in Bangladesh (BD)?

Answer: In Bangladesh (BD), the regular market price for the RADWAG AS 220.R2 PLUS Analytical Balance ranges between BDT 165,000 and BDT 185,000, depending on current import duties, custom configuration options, and warranty packages. For official corporate price quotes, institutional tenders, and direct stock availability in BD, contact authorized laboratory distributors such as Federal Scientific Mart (fsm.com.bd).

Q3: What warranty coverage and technical support are provided in Bangladesh?

Answer: The RADWAG AS 220.R2 PLUS comes standard with a 12-month (1-year) factory warranty covering weigh cell defects, internal calibration motor issues, and main electronic board failures. Authorized local suppliers like Federal Scientific Mart provide local technical support, ISO/GLP calibration certification, spare parts (glass doors, pan supports, leveling feet), and preventive maintenance across Bangladesh.

Q4: What are the advantages of internal automatic calibration in the AS 220.R2 PLUS?

Answer: The internal automatic adjustment mechanism continuously monitors ambient temperature changes and elapsed time. Whenever a significant temperature shift occurs or a set time interval passes, the balance automatically calibrates itself using an internal reference mass. This guarantees high measurement repeatability without requiring external certified calibration weights or manual operator intervention.

Q5: Which primary applications and weighing modes are supported?

Answer: The AS 220.R2 PLUS features built-in ALIBI memory and multiple dedicated application software modes:

• Standard Weighing: Precise mass determination in grams (g), milligrams (mg), carats (ct), and other units.

• Parts Counting: Automated piece counting for small components or tablets.

• Percent Weighing: Expressing sample weight as a percentage against a reference mass.

• Density Determination: Liquid and solid density testing (requires optional RADWAG density kit).

• Checkweighing & Dosing: High/low target limit verification for batch formulation.

• Statistics & GLP Reports: Automated statistical calculations and GLP/GMP-compliant printouts.

Q6: How do you set up and operate the balance step-by-step?

Answer:

1. Place the balance on a stable, vibration-free weighing table away from direct air currents or heat sources.

2. Adjust the front leveling feet until the bubble in the spirit level indicator is perfectly centered.

3. Plug in the power adapter and allow the balance to warm up for at least 30 minutes.

4. Close all draft shield doors and press the TARE/ZERO key to establish a zero baseline.

5. Open the side draft shield door, place your container onto the pan, close the door, and press TARE.

6. Gently place your sample onto the container, close the draft shield door, and read the final weight once the stability indicator appears on the LCD.

Q7: How do data logging and ALIBI memory protect measurement integrity?

Answer: The AS 220.R2 PLUS includes secure ALIBI memory capable of automatically recording up to 100,000 individual weighings. Each entry stores date, time, sample weight, tare value, and operator ID. This data cannot be altered or deleted, providing complete traceability that meets strict ISO, GLP, and GMP regulatory compliance standards.

Q8: How do you properly clean and maintain the balance?

Answer:

• Draft Shield Assembly: The glass doors and draft shield components can be easily disassembled without tools for quick cleaning.

• Weighing Chamber: Brush away loose powders or granules using a soft antistatic brush.

• Wiping: Wipe the stainless steel pan and glass panels with a lint-free cloth dampened with 70% ethanol or mild soapy water.

• Precaution: Avoid allowing liquid to enter the central loadcell mechanism beneath the pan support.

Q9: What items are included in the standard factory package when purchased?

Answer: The complete factory package includes:
