The company carries nearly 25 years of production and service experience, holds ISO 9001:2015 quality management system certification, and exports laboratory equipment to over 100 countries worldwide.<\/p>\n<h2>Factory Overview<\/h2>\n<div class=\"unionclay-resource-page__card\">\n<p>The manufacturing base sits in Zhengzhou, Henan Province \u2014 a recognized hub for laboratory instrument manufacturing in China. Production is in-house: the <a href=\"\/de\/products\/\">products page<\/a> states it plainly as own factory processing, and pricing is factory direct rather than trading-company markup. Equipment is manufactured with advanced CNC machining and precision glass processing technology.<\/p>\n<p>The factory builds temperature control equipment for heating and cooling, stirring and mixing devices, reaction systems, fermentation equipment, synthesis instruments, and separation and purification tools. These serve teaching applications, small-scale trials and mass production across biopharmaceuticals, the chemical industry and new energy testing. Customization is the part the team is most proud of: with nearly 25 years of production and service experience, UnionClay has completed hundreds of non-standard customization projects.<\/p>\n<\/div>\n<ul class=\"unionclay-resource-page__grid\">\n<li><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/www.unionclay.com\/wp-content\/uploads\/2026\/05\/1_0001_DSC01728.jpg\" alt=\"Rows of assembled rotary evaporators standing in the UnionClay factory workshop in Zhengzhou\" width=\"1200\" height=\"800\" \/>\n<p>Rotary evaporator assembly area inside the production workshop.<\/p>\n<\/li>\n<li><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/www.unionclay.com\/wp-content\/uploads\/2026\/05\/2_0000_DSC01722.jpg\" alt=\"Stainless steel and glass reactor units staged on the UnionClay factory floor before inspection\" width=\"1920\" height=\"750\" \/>\n<p>Reactor units staged on the factory floor.<\/p>\n<\/li>\n<li><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/www.unionclay.com\/wp-content\/uploads\/2026\/05\/2_0002_DSC01735.jpg\" alt=\"Jacketed glass reactors on frames lined up inside the UnionClay production hall\" width=\"1920\" height=\"750\" \/>\n<p>Jacketed glass reactors lined up in the production hall.<\/p>\n<\/li>\n<li><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/www.unionclay.com\/wp-content\/uploads\/2026\/05\/1_0000_DSC01717.jpg\" alt=\"Open control cabinet of a UnionClay temperature control unit showing the wiring and electrical components\" width=\"1200\" height=\"800\" \/>\n<p>Control cabinet of a temperature control unit during assembly.<\/p>\n<\/li>\n<li><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/www.unionclay.com\/wp-content\/uploads\/2026\/05\/2_0003_DSC01746.jpg\" alt=\"UnionClay equipment lineup outside the factory with reactors, rotary evaporators and recirculating chillers\" width=\"1920\" height=\"750\" \/>\n<p>Equipment lineup outside the factory: reactors, evaporators and chillers.<\/p>\n<\/li>\n<li><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/www.unionclay.com\/wp-content\/uploads\/2026\/05\/1_0002_DSC01678.jpg\" alt=\"UnionClay engineering and support team members working on laptops in the company office\" width=\"1200\" height=\"800\" \/>\n<p>Engineering and support team at the Zhengzhou office.<\/p>\n<\/li>\n<\/ul>\n<h2>Quality Management<\/h2>\n<div class=\"unionclay-resource-page__card\">\n<p>UnionClay holds ISO 9001:2015 quality management system certification and maintains professional R&amp;D and quality inspection teams. The published commitment is concrete rather than decorative: every glass reactor is individually assembled, inspected and vacuum-tested before shipment, with strict dimensional tolerances and surface finish standards maintained across production batches. Reactor vessels use certified G3.3 borosilicate glass with full material traceability, and all PTFE components are virgin-grade \u2014 no recycled or substandard materials.<\/p>\n<p>A supplier page should not ask you to take its word for anything. The table below maps each quality claim to where UnionClay already publishes it, so your sourcing team can check the original wording first-hand.<\/p>\n<\/div>\n<table>\n<thead>\n<tr>\n<th>Declared fact<\/th>\n<th>Where it is published on this site<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>ISO 9001:2015 quality management system certification<\/td>\n<td><a href=\"\/de\/about-us\/\">\u00dcber uns<\/a> \u2014 company history<\/td>\n<\/tr>\n<tr>\n<td>Nearly 25 years of production and service experience<\/td>\n<td><a href=\"\/de\/about-us\/\">\u00dcber uns<\/a> \u2014 company profile<\/td>\n<\/tr>\n<tr>\n<td>Products exported to over 100 countries worldwide<\/td>\n<td>About Us \u2014 company profile<\/td>\n<\/tr>\n<tr>\n<td>Own factory processing and 24-hour online service<\/td>\n<td><a href=\"\/de\/products\/\">Produkte<\/a> \u2014 contact panel<\/td>\n<\/tr>\n<tr>\n<td>ISO 9001 Certified and Factory Direct Pricing<\/td>\n<td><a href=\"https:\/\/www.unionclay.com\/\">Homepage<\/a> \u2014 SFS series banner<\/td>\n<\/tr>\n<tr>\n<td>Advanced CNC machining and precision glass processing<\/td>\n<td>Homepage \u2014 manufacturing process section<\/td>\n<\/tr>\n<tr>\n<td>G3.3 borosilicate glass, PTFE + Viton dual-seal system<\/td>\n<td>Homepage and About Us<\/td>\n<\/tr>\n<tr>\n<td>ISO 9001 certificate copies and product test reports on request<\/td>\n<td>About Us \u2014 documentation FAQ<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<h2>Product Range<\/h2>\n<p>Everything below is built and processed at the UnionClay factory.

Before quoting, the UnionClay team reviews the product family, target capacity, temperature or vacuum range, working medium, voltage, connector needs, matching equipment and customization notes \u2014 the quote reflects your process, not just a product name. If the process needs a connected workflow, matching equipment such as reactors, chillers, circulators, vacuum pumps or filtration units is confirmed in the same review.<\/p>\n<p>Common pre-purchase questions about documentation, OEM and customization are collected in the <a href=\"\/de\/faq\/\">Fragen und Antworten<\/a>.
