• 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: DLAB Levo pipette controllers come standard with a 12-month (1-year) factory warranty covering mechanical pump integrity, internal motor operation, and electronic charging board defects (for motorized variants).

• Local Support: Authorized local suppliers like Federal Scientific Mart provide local technical guidance, replacement hydrophobic filters, silicone adapters, and maintenance support across Bangladesh.

Q4: How do the manual Levo and electronic Levo Plus controllers differ in operation?

• Manual Levo / Levo E: Utilizes a thumbwheel design and squeeze bulb mechanism to provide sensitive liquid level regulation, effortless suction, and drip-by-drip drainage with color-coded sizing.

• Electronic Levo Plus: Features powerful motorized aspiration controlled via ergonomic finger buttons, an LCD screen for speed adjustment, and a lightweight design enabling effortless single-handed operation.

Q5: Which primary applications and industries utilize DLAB pipette controllers?

• Clinical & Diagnostic Labs: Safe liquid transfer, blood sample handling, and serial dilution procedures.

• Biotechnology & Research: Precise reagent addition, media preparation, and general solution handling in biology and chemistry workflows.

• Educational Institutions: Undergraduate and graduate teaching laboratories requiring dependable, safe pipetting aids.

Q6: How do you operate and execute liquid transfer using a Levo pipette controller step-by-step?

• Preparation: Ensure a clean hydrophobic filter (3.0 um or 0.45 um) and tight silicone pipette holder cone are securely installed.

• Insertion: Gently push the upper end of your glass or plastic serological pipette (0.1 mL to 100 mL) straight into the silicone adapter.

• Aspiration: Immerse the pipette tip into the liquid, then press the aspiration trigger (or rotate the thumbwheel) to draw liquid up to or slightly above your desired graduation mark.

• Dispensing: Press the dispense button (or use gravity drainage) to empty the liquid accurately, utilizing the blow-out feature if working with blow-out pipettes.

Q7: What safety protections prevent liquid from entering the internal mechanism?

• Hydrophobic Filter Barrier: Equipped with a replaceable inline hydrophobic membrane filter that effectively blocks liquid aerosols and accidental over-aspirated fluid from penetrating the internal pump system.

Q8: How do you properly clean and maintain the pipette controller?

• Cone & Adapter Sterilization: The silicone pipette holder cone and nosepiece can be easily disassembled and autoclaved or cleaned with 70% isopropyl alcohol.

• Housing Care: Wipe down the outer casing with a clean, damp cloth. Never submerge motorized electronic units in water.

• Filter Replacement: Regularly inspect and replace the hydrophobic filter if fluid exposure occurs or if aspiration suction noticeably slows down.

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

• Main Unit: DLAB Levo Pipette Controller (Manual or Motorized Levo Plus body).

• Power Supply (Electronic Models): Universal power adapter and charging stand or cable.

• Accessories: Spare hydrophobic filters and user instruction manual with a quality inspection certificate.
