Frequently Asked Questions (FAQ)

1. Q What is the total magnification range of the L101 Microscope?

The L101 Microscope (XSP-L101) delivers seven magnification levels: 25X, 50X, 100X, 150X, 225X, 450X, and 675X. The instrument achieves these levels by combining three achromatic objective lenses (5X, 10X, 45X) with three interchangeable eyepieces (5X, 10X, 15X). Students and lab technicians can switch between levels instantly using the triple nosepiece click-stop mechanism.

2. Q Is the L101 Microscope suitable for secondary school students in Bangladesh?

Yes. The L101 is one of the most widely used student biological microscopes in school laboratories across Bangladesh. Its simple coarse and fine focusing system, sturdy all-metal frame, and 25X–675X magnification range fully meet the requirements of the secondary school biology curriculum. Teachers and lab assistants find it easy to maintain and operate, and students learn the fundamentals of microscopy quickly on this instrument.

3. Q How do I switch between magnifications on the L101?

The L101 carries a triple nosepiece that rotates with a firm click-stop at each objective position. To change magnification, users simply rotate the nosepiece until they feel and hear the click that confirms the new objective is in the optical path. After switching, users re-focus using the coarse adjustment knob and then fine-tune with the fine adjustment knob. Swapping eyepieces (5X, 10X, 15X) provides additional magnification steps without moving the nosepiece.

4. Q Does ASTZBD supply glass slides and accessories with the L101?

Yes. ASTZBD stocks a range of compatible accessories alongside the L101 Microscope, including prepared biology slide sets, blank glass slides, cover slips, immersion oil, lens cleaning tissue, and carrying cases. Buyers can add these items to their order to receive a complete ready-to-use microscopy kit in a single delivery.
