Import Biological Microscope — Buy in wholesale FOB from Supplier in China

The XSP-300D is a monocular biological microscope designed for routine brightfield observation, offering magnifications from 40x to 1600x when fitted with optional WF16x eyepieces. Its compensation-free monocular head is inclined at 45 degrees, a configuration that conserves bench space and simplifies training in multi-user classroom settings. The standard objective set comprises achromatic 4x, 10x, 40x spring, and 100x spring oil-immersion lenses on a 160 mm tube-length body, with a 120 mm x 125 mm double-layer mechanical stage and an Abbe condenser of N.A. 1.25 for controlled light cone formation.

Illumination is provided by a 1W LED as standard, with a 3W LED variant available for users requiring higher luminous flux for dense or poorly stained specimens. Focus control offers 30 mm of coarse travel and 30 mm of fine travel, with the fine adjustment typically graduated to resolve sub-micron stage displacement, a specification standard for instruments in this educational tier. The power module accepts 220V or 110V AC input and delivers 6V DC to the LED, making it compatible with most laboratory and school electrical infrastructures without external transformer. The YANYANG-branded unit is packed in plastic foam within a carton for export, with Shanghai as the default departure port.

This model suits secondary-school biology departments, technical college laboratories, and agricultural extension stations where individual student use is intermittent and budget constraints are firm. The monocular format reduces per-unit cost compared to binocular or trinocular alternatives, though it sacrifices stereo depth perception and photographic adaptability. Buyers should confirm eyepiece inclusion, LED wattage, and carton quantity per master case before finalising purchase. Lead time runs to 20 days for orders of 1-1000 units, with larger volumes subject to direct negotiation with the Wuxi office.

Wuxi Yanyang International Trading Co., Ltd. operates from 1802, Yang Ming Building, No.588 Nanhu Avenue, Liangxi District, Wuxi, Jiangsu, China, serving as an export trading company for optical and laboratory equipment. The firm's profile shows a Harbor trust tier, the baseline verification level, with no advanced audit or on-site inspection badges displayed. Response metrics indicate a 0.00 percent response rate and zero average response hours, which signals that enquiry handling may be inconsistent or that the account is not actively monitored through the platform messaging system.

The XSP-300D is marketed under the supplier's own YANYANG brand, distinguishing it from the OEM-branded XSP-MV sister model. No information is provided about in-house manufacturing versus third-party sourcing, ISO 9001 or ISO 13485 certification, after-sales service infrastructure, or domestic market share. Buyers should therefore treat the company as a trading house until proven otherwise, and conduct due diligence on factory identity, quality control checkpoints, and warranty claim procedures before committing to volume orders.
