To maximize the lifespan, accuracy, and efficiency of your Micro Pipette DLAB, understanding its internal structure, selection criteria, advanced operational workflows, and maintenance protocols is essential. Below is an expanded technical manual designed for laboratory managers, researchers, and science students.
1. Anatomy and Functional Components / অ্যানাটমি এবং কার্যকরী অংশসমূহ
-
Plunger Button (প্লাঞ্জার বাটন): Located at the very top, it controls both the liquid aspiration and the blowout/dispense steps through a reliable two-stop mechanism.
-
Volume Adjustment Knob (ভলিউম অ্যাডজাস্টমেন্ট নব): Turned smoothly to set the desired microliter volume, connected to an internal precision micro-meter screw.
-
Tip Ejector Arm (টিপ ইজেক্টর আর্ম): A mechanical rod running alongside the shaft that pushes used plastic tips off the cone cleanly without manual hand contact, minimizing biological contamination risks.
-
Shaft and Tip Cone (শ্যাফট এবং টিপ কোন): The lower extension where disposable polymer tips attach securely. This part requires an airtight seal to ensure accurate liquid suction.
2. Detailed Two-Stop Pipetting Technique / টু-স্টপ পাইপেটিং টেকনিকের বিস্তারিত ধাপ
Achieving high accuracy with single-channel adjustable micro pipettes requires mastering the two-stop technique:
-
First Stop (First Resistance Point): Press the plunger smoothly down to the first natural resistance point. This defines the exact volume of air to be expelled.
-
Aspirating Liquid: Immerse the tip vertically into the liquid (1–3 mm deep) and release the plunger in a slow, controlled, and uniform manner. Never snap the plunger back abruptly.
-
Dispensing to the First Stop: Place the tip against the interior wall of the receiving vessel at a 10–30 degree angle. Press the plunger down smoothly only to the first stop. Pause for 1–2 seconds to ensure complete liquid delivery.
-
Blowout (Second Stop): Press the plunger past the first stop all the way down to the second stop to expel any residual droplets remaining in the tip.
3. Selection Guide Based on Volume Ranges / ভলিউম রেঞ্জ অনুযায়ী সঠিক পাইপেট নির্বাচন
DLAB pipettes are available in various adjustable volume ranges to suit diverse scientific applications:
-
0.1–2.5 µL or 0.5–10 µL: Ideal for molecular biology, PCR setups, DNA amplification, and sensitive enzyme assays.
-
2–20 µL / 10–100 µL: Frequently used in general biochemistry, clinical chemistry, and ELISA testing protocols.
-
100–1000 µL (1 mL): Suitable for larger reagent transfers, buffer preparation, and routine cell culture media handling.
4. Comprehensive Troubleshooting Guide / সমস্যা সমাধান নির্দেশিকা (ট্রাবলশুটিং) Micro Pipette DLAB
-
Problem: Bubbles appearing during liquid aspiration.
-
Cause: Tip is not securely attached, or the tip is immersed too deep or too shallow.
-
Solution: Firmly press a new matching tip onto the cone and check the immersion depth (1 to 3 millimeters).
-
-
Problem: Inaccurate volume delivery or leaking.
-
Cause: Worn-out O-rings, internal piston contamination, or chemical residue buildup.
-
Solution: Clean the lower shaft, inspect the sealing rings, and perform recalibration using standard analytical balance mass-checking methods.
-
-
Problem: Stiff or sticking plunger movement.
-
Cause: Dried chemical residue or lack of proper internal piston lubrication.
-
Solution: Disassemble the lower component carefully, clean with authorized laboratory solutions, and apply designated silicone grease to the piston.
