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

Answer: In Bangladesh (BD), the regular market price for the Four E's Scientific WB101 2L Water Bath typically ranges between BDT 25,000 and BDT 32,000, depending on import shipping tariffs, stock availability, and supplier warranty 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 Four E's Scientific WB101 comes standard with a 12-month (1-year) factory warranty covering heating element failures, touch panel defects, and internal sensor malfunctions. Authorized local suppliers like Federal Scientific Mart provide local technical guidance, replacement lids, fuse units, temperature probes, and maintenance support across Bangladesh.

Q4: What safety mechanisms are integrated into the WB101 water bath?

Answer:

• Dry-Start Protection: Automatically cuts off power if the bath is turned on without sufficient water, preventing heating element burn-out.

• Over-Temperature Cut-Off & Alarm: Built-in thermal protection system sounds an alarm and shuts off heating if the water temperature exceeds safe limits, protecting sensitive samples from overheating.

• Insulated Stainless Steel Design: Seamless chamber construction prevents liquid leaks and minimizes external chassis heating during long runs at 99 degrees C.

Q5: Which primary laboratory applications utilize the 2L WB101 water bath?

Answer: The compact 2-liter footprint makes the WB101 ideal for low-volume general laboratory and clinical tasks, including:

• Incubation of biological samples, cultures, and enzymatic assays.

• Sample thawing, warming reagents, and media preparation.

• Industrial quality control testing requiring stable low-to-medium thermal environments.

Q6: How do you operate and set up the WB101 water bath step-by-step?

Answer:

1. Place the water bath on a flat, stable, heat-resistant workbench.

2. Fill the stainless steel chamber with distilled or deionized water, ensuring the liquid level covers the bottom heating element surface while leaving room for sample immersion.

3. Plug the power cord into a properly grounded electrical outlet and turn on the main switch.

4. Use the touch keys on the front glass panel to set your desired temperature (e.g., 37 degrees C) and run duration (1 to 999 minutes).

5. Place the transparent lid on top to accelerate heating and stabilize internal thermal uniformity.

6. Once the LED display confirms the set temperature is reached, place your samples into the bath; the unit will maintain stability and auto-stop when the timer finishes.

Q7: How do you properly clean and maintain the water bath?

Answer:

• Draining & Rinsing: Unplug the unit, let it cool completely, and empty the water reservoir regularly. Clean the stainless steel chamber with a soft sponge and mild neutral detergent.

• Scale Prevention: Use distilled or deionized water to prevent mineral scale buildup on the stainless steel surface and temperature sensor probe.

• Prohibition: Never use harsh abrasive scouring pads, steel wool, or corrosive bleach solutions on the stainless steel tank or glass touch panel.

Q8: What items are included in the standard factory package when purchased?

Answer: The complete factory package includes:

• Four E's Scientific WB101 2L Water Bath main unit
