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

• Price Range: In Bangladesh (BD), the regular market price for the DLAB MS-H280-Pro Hotplate Stirrer typically ranges between BDT 30,000 and BDT 38,000, depending on import duties, shipping tariffs, and whether the Pt1000 external sensor probe is bundled.

• Procurement Procedure: 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?

• Warranty Terms: The DLAB MS-H280-Pro comes standard with a 12-month (1-year) factory warranty covering heating element failures, internal brushless/stepping stirring motor defects, and digital control board faults.

• Local Support: Authorized local suppliers like Federal Scientific Mart provide professional technical guidance, PT1000 sensor replacements, heating plate maintenance support, and repair service across Bangladesh.

Q4: How do the ceramic-coated workplate and Pt1000 sensor enhance thermal performance?

• Rapid Heating & Corrosion Resistance: The 135 mm aluminum workplate coated with ceramic provides exceptional thermal conductivity alongside robust resistance against chemical spills and aggressive acids.

• Precise Medium Feedback: When plugged in, the optional Pt1000 external temperature sensor immerses directly into the liquid sample, giving real-time feedback to maintain exact solution temperatures rather than just plate surface temperature.

Q5: Which primary applications and industries utilize the MS-H280-Pro?

• Chemical Synthesis & Formulation: Routine organic synthesis, solution preparation, and chemical reaction refluxing.

• Biochemistry & Life Science Labs: Media dissolution, buffer preparation, and temperature-controlled sample mixing.

• Academic & Industrial R&D: University teaching laboratories and general industrial quality control testing.

Q6: How do you operate and set up the MS-H280-Pro step-by-step?

• Placement: Place the 1.8 kg unit on a clean, stable, flat, and heat-resistant laboratory benchtop.

• Power & Sensor Connection: Plug the power cord into a grounded electrical outlet and plug the Pt1000 temperature sensor into the rear port if direct liquid monitoring is required.

• Vessel Placement: Center your glass beaker or flask containing a magnetic stir bar onto the 135 mm ceramic workplate.

• Parameter Setup: Turn on the power switch, use the digital rotary knobs to set your target stirring speed (up to 1500 rpm) and heating temperature (up to 280 degrees Celsius).

• Execution: Press the knobs to initiate stirring and heating. The LCD will display real-time values.

• Shutdown: Turn off heating and stirring after use, allowing the workplate to cool down completely before cleaning.

Q7: What safety mechanisms are integrated into the hotplate stirrer?

• Hot Surface Warning: Features a prominent "HOT" flashing warning indicator when plate temperature exceeds 50 degrees Celsius, even after the unit is powered off, preventing accidental burns.

• Over-Temperature Protection: Internal safety circuit automatically cuts off heating if temperatures exceed the 320 degrees Celsius threshold.

Q8: How do you properly clean and maintain the hotplate stirrer?

• Workplate Care: Ensure the ceramic-coated aluminum plate is cool to the touch, then wipe down chemical residue using a soft cloth dampened with mild detergent or 70 percent isopropyl alcohol. Avoid abrasive scouring pads.

• Housing Maintenance: Keep the outer casing free of moisture and chemical splashes. Do not submerge the unit in water.

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

• Main Unit: DLAB MS-H280-Pro Circular Magnetic Hotplate Stirrer main body.

• Accessories: Magnetic stir bar and power cord (Pt1000 temperature sensor support rod assembly included depending on bundle configuration).

• Documentation: User instruction manual and factory quality inspection certificate.

Q10: Why purchase DLAB laboratory equipment from Federal Scientific Mart (fsm.com.bd)?

• Genuine OEM Supply: 100% authentic DLAB Scientific heating and mixing equipment imported directly from certified manufacturing lines with official serial tracking.
