101Lab by GreenBidz is a B2B marketplace for buying and selling pre-owned laboratory, pharmaceutical, test, measurement and industrial equipment across Asia and other served markets. Its listings include instruments such as HPLC systems, centrifuges and bioreactors, with equipment traded by telecom carriers, electronics manufacturing services plants, utilities and university laboratories. The marketplace serves buyers and sellers in 12 countries and reports more than 3,000 live instruments and over USD 50 million in equipment traded.

Transparency is central to the service: 101Lab says 98% of equipment is inspection-verified, and listings state calibration details, service history and licence information. Buyers can browse auctions and direct-sale listings, make offers, or add services such as calibration, bench testing, installation and training. Payments can be held in escrow through a ten-day acceptance window, with funds released after the buyer approves the performance check.

For sellers, GreenBidz offers free equipment valuations, options to sell as-is or serviced and calibrated, storefronts for power sellers, and assistance with lab or site clearances.
