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

Answer: In Bangladesh (BD), the regular market price for the Lovibond Model F Visual Colorimeter typically ranges between BDT 850,000 and BDT 1,050,000+, depending on import freight, custom duties, included glass cell path lengths, and local supplier support packages. For official corporate price quotations, institutional tenders, and direct stock verification 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 Lovibond Model F comes standard with a 12-month (1-year) factory warranty covering mechanical housing, optical prism assembly defects, and electrical power pack failures. Authorized local suppliers like Federal Scientific Mart provide local technical guidance, replacement halogen bulbs, sample chamber liners, calibration support, and spare glass color filters across Bangladesh.

Q4: How does the prismatic optical system ensure accurate visual color matching?

Answer: The Model F utilizes an advanced prismatic optical viewing tube that arranges two adjacent fields of view side by side. Operators observe the sample in the left field and a standard white reflective surface (illuminated by the internal halogen lamps) in the right field. This balanced, split-field optical design allows seamless visual comparison between the product's transmitted or reflected light and the calibrated Lovibond glass standards.

Q5: What purpose do the Neutral glass color filters serve in the filter racks?

Answer: Alongside the traditional Red, Yellow, and Blue glass filter racks, the Model F includes a series of Neutral glass filters. These can be introduced into the sample field to "dull" or adjust the brightness of exceptionally vivid or high-chroma samples, ensuring a precise and balanced visual color match without distorting the underlying hue values.

Q6: Which primary industries and sample types are tested using the Model F?

Answer: The Lovibond Model F is the industry standard for color grading transparent and opaque materials across multiple sectors:

• Edible Oils & Fats: Measuring animal and vegetable oils, cooking oils, mustard oil, sesame oil, and fats according to BS 684 and AOCS specifications.

• Petroleum & Fuels: Grading petroleum oils, diesel, lubricants, and waxes.

• Chemicals & Pharmaceuticals: Evaluating industrial chemicals, resins, varnishes, and liquid solutions.

• Solids & Powders: Grading opaque solids, powders, and pastes using optional reflectance accessories.

Q7: How do you operate and perform a colour measurement on the Model F step-by-step?

Answer:

1. Clean the appropriate fused glass sample cell (e.g., 1 inch or 5 1/4 inch path length) and fill it with the clear, liquid sample.

2. Place the filled sample cell into the sample chamber on the replaceable white sample chamber liner.

3. Turn on the top-mounted IP68-sealed illumination switch to light up the sample and the white reference reflector.

4. Look through the viewing tube and slide the Lovibond Red, Yellow, Blue, and Neutral glass filter racks into position.

5. Adjust the racks until the color in the comparison field perfectly matches the sample field.

6. Read the exact color value in Lovibond units directly from the rack scales and record your results.

Q8: How do you properly clean and maintain the Model F colorimeter?

Answer:

• Sample Chamber Maintenance: The instrument features a removable white plastic sample chamber liner. If oil or liquid spills occur, slide out the liner, clean it with solvent/detergent, or replace it to maintain the pristine white background essential for accurate color matching.

• Optics Care: Clean the viewing tube lenses and glass standards periodically with a clean lens tissue and optical cleaning solution.

• Lamp Replacement: Replace blown tungsten halogen lamps with identical 12V, 10W matched pairs to maintain standardized lighting temperature.

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

Answer: The complete factory package includes:
