Product Description
The DLAB StepMate Stepper mechanical repeater pipette delivers accurate repetitive liquid dispensing for molecular biology, clinical testing, biochemical research, and pharmaceutical laboratories across Bangladesh. Operating on the positive displacement principle, this lightweight repeater pipette provides reliable dispensing for standard solutions as well as high-viscosity liquids, high-density fluids, and volatile solvents without risk of liquid contamination.
Equipped with a five-position volume selection dial and slide lever, the StepMate provides flexible dispensing options up to 48 sequential steps from a single filling. Operators easily select target volumes ranging from 10 µL to 5000 µL (5 mL) depending on the tip size and dial setting used. The ergonomic, slim body design allows smooth single-handed operation, reducing manual effort during high-throughput aliquot dispensing tasks.
Engineered for broad laboratory utility, the StepMate accommodates seven different sizes of disposable polypropylene stepper syringes/tips ranging from 0.5 mL to 50 mL capacity. The maintenance-free mechanical system features a durable tip insertion and stop lever for secure tip attachment and smooth ejection. With lightweight construction (105 g) and simple manual operation, this instrument provides an efficient liquid repetitive handling solution.

Q1: What are the official technical specifications of the DLAB StepMate Stepper Pipettor?
Model: DLAB StepMate Stepper Pipettor (Mechanical Positive Displacement Repeater Pipette).
Dispensing Volume Range: 1 microliter (uL) to 5 milliliters (mL).
Number of Dispensing Steps: Up to 73 different dispensing steps per syringe tip filling.
Compatibility: Fully compatible with standard disposable dispenser syringes in 8 different sizes (from 0.05 mL to 50 mL).
Dispensations per Filling: Allows up to 49 repeated dispensions without refilling depending on the selected syringe size and volume step.
Mechanism: Mechanical positive displacement piston system designed for high-viscosity, high-density, and high-vapor-pressure liquids.
Net Weight: Lightweight, ergonomic housing weighing approximately 105 grams.
Q2: What is the price and local procurement procedure in Bangladesh (BD)?
Price Range: In Bangladesh (BD), the regular market price for the DLAB StepMate Stepper Pipettor typically ranges between BDT 12,000 and BDT 16,000, depending on import duties, shipping tariffs, and bundled dispenser syringe starter packs.
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 StepMate comes standard with a 12-month (1-year) factory warranty covering internal mechanical ratchet gear assemblies, volume selector locks, and piston housing alignment.
Local Support: Authorized local suppliers like Federal Scientific Mart provide professional technical guidance, compatible dispenser syringe tip supply, and maintenance support across Bangladesh.
Q4: How do the positive displacement mechanism and multi-step dispensing enhance efficiency?
Repeated Aliquoting: Eliminates the need to refill between every single drop by allowing up to 49 consecutive aliquots from a single syringe aspiration.
Viscous & Volatile Sample Handling: Positive displacement piston design creates a direct seal against the liquid, ensuring flawless, bubble-free dispensing of viscous, dense, foaming, or volatile reagents (such as glycerol, oils, and alcohols) where air-displacement pipettes fail.
Q5: Which primary applications and industries utilize the StepMate stepper pipettor?
Molecular Biology & PCR Labs: High-throughput serial dispensing of master mixes, enzymes, and buffers across multi-well plates.
Pharmaceutical & Industrial QC: Routine sample aliquoting, reagent distribution, and packaging quality control.
Clinical & Diagnostic Laboratories: Diagnostic kit preparation and serial dilution workflows.
Q6: How do you operate and set volume on the StepMate step-by-step?
Tip Selection & Attachment: Select the appropriate size of disposable dispenser syringe tip based on your desired aliquot volume, and lock it securely into the lower coupling mechanism.
Volume Selection: Consult the volume selection table on the pipettor body, and set the adjustment wheel to match your target aliquot size.
Aspiration: Slide the filling lever downward smoothly to draw liquid into the syringe tip.
Dispensing: Position the tip over your vessel and press the dispensing button repeatedly to deliver precise, equal aliquots step by step until the syringe is empty.
Ejection: Release and discard the used syringe tip into a biohazard receptacle.
Q7: What maintenance and cleaning procedures are required for the StepMate?
Exterior Care: Wipe down the outer plastic casing with a soft cloth dampened with 70 percent isopropyl alcohol or mild soap water. Do not submerge the main mechanical body in liquid.
Storage: Store the instrument in a clean, dry place on a dedicated pipette stand when not in use. The StepMate requires no routine internal lubrication of the mechanical gear path.
