Import Bioligical Compound Microscope For Students — Buy in wholesale FOB from Supplier in China

The XSP-03 biological compound microscope from Wuxi Yanyang International Trading Co., Ltd. targets student-level instruction with a monocular head configuration and H5X and H10X Huygens eyepieces paired with 10X, 40X, and 100X achromatic objectives. This optical arrangement yields magnification ranges from 50X through 1,000X, including oil immersion capability at the highest power, a feature less commonly found in entry-level educational instruments. The N.A.=1.25 Abbe condenser with iris diaphragm and filter represents a step up from basic disc diaphragm systems, permitting more precise control of numerical aperture and contrast for translucent specimen observation. Focus mechanism provides 50mm coarse travel and 1.8-2.2mm fine adjustment range, the latter suggesting a relatively high gear ratio suitable for critical focusing at 400X and 1,000X magnifications. A 120mm by 120mm plain stage with moving scale assists approximate specimen location, though full mechanical translation is not included as standard. Concave-plan reflector of 50mm diameter serves as the base illumination source, with extra LED lamp listed as optional.

The inclusion of a 100X oil immersion objective distinguishes this model from pure introductory instruments, enabling observation of bacterial morphology and blood cell detail that 40X maximum systems cannot resolve. Huygens eyepiece design, indicated by the H-prefix, is an older optical form with smaller eye relief and field of view than modern Wide Field or SWF alternatives, acceptable for student use but potentially uncomfortable for eyeglass wearers during extended sessions. The Abbe condenser's 1.25 numerical aperture matches or exceeds typical objectives in the set, allowing full aperture illumination without vignetting, provided the condenser is properly centred and focused. Moving scale on the plain stage aids in recording and relocating approximate field positions, though it lacks the precision of Vernier-equipped mechanical stages. The concave mirror reflector operates only in ambient light conditions, making the optional LED lamp practically essential for interior classrooms without strong window illumination or during evening laboratory sessions.

Purchaser demographics overlap with the XSP-102YF, encompassing secondary schools, technical colleges, and vocational training programmes, with additional relevance to introductory university biology courses where oil immersion technique is taught. The 10,000 set monthly capacity figure matches the companion listing, suggesting common sourcing or shared production planning. Port of departure is again Shanghai, with identical 20-day lead time for quantities through 1,000 units and negotiated schedules beyond. Buyers comparing this model against the XSP-102YF should weigh the oil immersion capability and superior condenser against the Huygens eyepiece limitation and mirror-based default illumination. Direct negotiation with Wuxi Yanyang remains necessary to confirm actual pricing, eyepiece interchangeability between models, and whether volume discounts apply to mixed orders across multiple microscope specifications.

Wuxi Yanyang International Trading Co., Ltd. is registered at the identical Wuxi address across both microscope listings, 1802, Yang Ming Building, No.588, Nanhu Avenue, Liangxi District, postal code 214000, Jiangsu Province, China. The Harbor trust tier and zero response rate metrics apply consistently, indicating these are sibling listings from a single supplier profile rather than independent entities. The Yang Ming Building location in Liangxi District places the company in a commercial office zone of Wuxi, a city with established optical instrument manufacturing heritage but also significant trading company density for educational equipment export.

The firm's presentation of two distinct microscope models, XSP-102YF and XSP-03, with different optical specifications suggests either direct manufacturing relationships with multiple OEM factories or flexible sourcing arrangements within the Jiangsu optical cluster. No ISO certification, factory audit results, or research and development credentials appear in the disclosed profile. The shared 10,000 set monthly capacity across both products may reflect aggregate trading volume rather than single-factory output. Buyers evaluating Wuxi Yanyang as a supplier should request factory identification for quality traceability, warranty claim processing protocols, and evidence of previous successful deliveries to educational institutions in comparable markets. The absence of response rate data emphasises the need for proactive direct communication rather than platform-mediated inquiry alone.
