What PT. Rahayu Santosa (Indonesian Bus Factory) does

九州平台-九州网站医疗 (Perlong Medical) is a privately-held Chinese in vitro diagnostic (IVD) medical equipment manufacturer established in 1993, headquartered in Shunyi District, Beijing, with an R&D and manufacturing subsidiary — Nanjing Perlong Medical Equipment Co., Ltd. — in Nanjing's Jiangning Economic and Technological Development Zone, and a second wholly-owned subsidiary, Nanjing Perlong Biomedical Co., Ltd., focused on biomedical reagents. The group operates under the Perlong and Perfebio brand names and is led by Chairman Liu Jinhu (刘金虎) with General Manager Chunlin (淳林) overseeing operations.

The company's product portfolio spans clinical laboratory equipment — blood gas/biochemistry analyzers (PL2000PLUS, PL2200, PL2000 sharp-electrode series with proprietary solid-state electrode technology), ELISA microplate readers and washers (DNM-9602/9606, DNX-96/9620 series), coagulation analyzers (PUN-2048A/B), ESR analyzers (PUC-2068A/B, PUC-100 series), biochemistry analyzers (PUS-2018/2018G/2018N), automated nucleic acid extractors (PLH-32/48, magnetic-bead method), chemiluminescence immunoassay analyzers (PHX-60), specific protein analyzers (PA8800, three-dimensional nephelometry), and a dedicated reagent catalog covering blood gas electrolytes, cardiac markers (cTnI, cTnT, MYO, CK-MB, NT-proBNP, H-FABP, MPO, D-dimer), inflammation markers (CRP, PCT, IL-6, SAA), and immunocolloidal gold kits under the Perfebio sub-brand. The portfolio extends beyond clinical labs into veterinary disease detection (DWB-96/96G/24 series for swine fever, avian flu, Newcastle disease) and food safety / pesticide residue testing (PLS-96/96G/24, PLNC-16/24/32 series).

The business model is B2B direct sales to medical and public-sector institutions — hospitals (tertiary, secondary, and primary), CDC, blood stations, entry-exit quarantine bureaus, research universities, animal disease prevention centers, and food inspection authorities — across 30+ Chinese provinces and municipalities with exports to multiple international markets. Revenue is generated through instrument hardware sales plus recurring reagent/consumable sales, with one-stop after-sales service (installation, training, repair) provided directly. Distribution is conducted via the company's own direct sales force, the 400-696-6267 consultation hotline, and the corporate website; no third-party channel partnerships or public pricing are disclosed. The group has received national-level recognition through the 2012 National Science and Technology Support Program designation (Ministry of Science and Technology) and a 2015 research collaboration with Nanjing University of Science and Technology, but no funding rounds, M&A activity, or public-market filings are present in the source data.

• Maccura Biotechnology: Sichuan-based Chinese IVD manufacturer with biochemistry, chemiluminescence, molecular diagnostics, and POCT products. Comparable to Perlong as a similarly-sized domestic IVD player competing for the same hospital and government laboratory tenders.
• Wondfo Biotech: Guangzhou-based Chinese POCT and IVD manufacturer. Comparable for the rapid-test, infectious disease, and veterinary diagnostic reagent lines, with similar go-to-market approach to grassroots Chinese healthcare and government buyers.
• Autobio Diagnostics: Zhengzhou-based Chinese IVD manufacturer with chemiluminescence, microbiology, and clinical chemistry platforms. Comparable as a mid-tier Chinese IVD player targeting similar hospital and CDC customers with bundled equipment + reagent offerings.
• Snibe (Shenzhen New Industries Biomedical Engineering): Chinese chemiluminescence immunoassay specialist with global installed base. Directly comparable to Perlong's PHX-60 chemiluminescence immunoassay analyzer line and magnetic particle chemiluminescence reagent kits (cardiac markers, infectious disease), targeting the same hospital lab customers.
• Mindray Bio-Medical Electronics: Shenzhen-headquartered Chinese IVD and patient monitoring leader. Directly comparable as a Chinese mid-to-high tier IVD manufacturer with broad equipment (chemistry, immunoassay, hematology, blood gas) plus reagent portfolios serving hospitals across China and internationally — Perlong operates one tier below in scale but in the same product categories.

Broad incumbents

• Bio-Rad Laboratories: Global life science and clinical diagnostics company with BioPlex multiplex immunoassay, quality controls, and blood bank screening products. Comparable for the IVD reagent and quality control consumable side of Perlong's business.
• Beckman Coulter Diagnostics: Global IVD manufacturer (Danaher subsidiary) with Access immunoassay, DxH hematology, and AU clinical chemistry lines. Comparable as an established foreign IVD incumbent competing for the same Chinese hospital laboratory tenders as Perlong.
• Siemens Healthineers: Global IVD and imaging incumbent with Atellica immunoassay, ADVIA Centaur, and RAPIDPoint blood gas analyzers — overlapping with Perlong's portfolio. Comparable as an established foreign incumbent that Perlong competes against in mid- and high-tier Chinese hospital bids.
• Roche Diagnostics: Global IVD market leader across immunoassay, clinical chemistry, molecular, and tissue diagnostics. Comparable as the high-end benchmark that Perlong's mid-tier equipment and reagents compete against in Chinese hospital tenders, though Roche operates at much larger scale and in broader geographies.
• Abbott Diagnostics: Global IVD incumbent with strong presence in immunoassay (Architect), point-of-care (i-STAT blood gas — a direct competitor to Perlong's blood gas analyzers), and rapid diagnostics. Comparable for product overlap with Perlong's PL2000PLUS blood gas and chemiluminescence lines.
