上海屹尧科技PreeKem 
上海屹尧仪器科技发展有限公司成立于2000年，是一家专业研制、开发、生产微波化学设备的高新技术企业。公司10余名专业研发人员均具有多年微波及相关设备开发和生产的经验。公司主要产品有：微波消解仪、微波萃取仪、微波合成仪、微波马弗炉和微波消解辅助设备等。

　　公司体制与员工都相当富有活力。公司在化学专业领域一直锐意进取，不断自主研发新品，填补国内空白。经过几年来不懈的努力，本公司具有自主知识产权的产品在性能上已达到国际领先水平，且具有价格低、操作界面中文化、售后成本低、售后服务快速等优势。2001年，早在公司成立初期，我公司就研制出国内第一台具有温度，压力双重控制的商品化微波消解仪WX-2000型，广受业界和用户好评；2004年1月，WX-3000型温压双控微波消解仪被评定为上海市高新技术成果转化项目最高等级“A级”；2005年，公司又推出改良升级版——框架式结构高压消解罐WX-4000型微波消解仪。

　　2005年起，公司在产品研发中采用全新设计理念，于10月同时推出三款堪与国际产品媲美的微波化学仪器，WX-8000专家型微波消解仪、Excel全功能型微波化学工作平台（微波消解/萃取/合成）和国内首台微波马弗炉WM-1，充分显示了公司强大的研发实力。其中Excel微波化学工作平台还获得中国仪器仪表学会分析仪器学会颁布的2006年度新产品荣誉。2007初，公司正式发布全新“Apex常压微波合成/萃取系统”，进一步巩固了我公司在业界的技术领先地位。该系统是目前国内唯一采用专用工业级微波谐振腔、高精度高频光纤温度传感器并配合高频闭环反馈人工智能控制的常压式微波化学实验仪器。2009年公司采用全新的设计理念，打造了智能微波化学工作平台EXCEL-2010。

　　近年来，公司在各个方面迅猛发展。2004年6月，公司率先通过ISO9001:2000国际质量体系认证，成为行业发展的新标杆。同年，公司相继在北京、广州、成都开设了联络处和维修站，以便为广大国内用户提供更迅捷、更优质的服务。除了固有的国内市场，公司还从06年初开始积极介入国外市场，目前已成功销往意大利、俄罗斯、土耳其、日本、澳洲、韩国、台湾、印度、伊朗、巴基斯坦等国家和地区。

　　公司立志研制开发具有自主知识产权的国产科学仪器，致力于创造一个洁净、快速、环保的化学前处理平台，使实验室前处理工作简单化、智能化、精确化。公司过去的成绩鞭策着我们对产品和服务提出更高的要求。未来，公司将精益求精地开发推动行业技术进步的尖端产品，严格把关产品和服务质量，一如既往地为国内外客户提供优质服务。

Founded in 2000, PreeKem has been researching and innovating in the development of Microwave & Sample Pretreatment System. The company has more than ten professionals experienced in research & development of microwave products. Currently PreeKem has SUPEX, EXCEL and WX-4000 Microwave Digestion System, Automated Microwave Synthesizer, NOVA-II Microwave Synthesizer, APEX Atmospheric Microwave Synthesis & Extraction System, RAPTOR Microwave High Temperature Muffle Furnace, Q2 Microwave Moisture/Solids Analyzer and EXTRA Automated Solid Phase Extraction System in its Product line.

As a young and energetic company, PreeKem is attractive in good quality system and innovative staff. It has been forging ahead in the scope of microwave chemistry and further developing specific novel products successfully and independently. After several years of unremitting efforts, PreeKem's products with independent intellectual property rights have been reaching the international advanced level, while they are much more than attractive for their lower price, Chinese intelligence of product design and inexpensive operational cost. In 2001, the company launched a microwave digestion system, WX-2000, with temperature and pressure dual-controlled which is well-recognized by insiders and customers. In January 2004, WX-3000 temperature and pressure dual-controlled microwave digestion system was selected as Grade-A product, the highest level in Shanghai Hi-tech research transforming project. In 2005, the company started to adopt new concept of design in its research and development of products. Except for updated microwave digestion system of WX-4000, the company launched three microwave chemical equipments, WX-8000 Microwave Digestion System, EXECL Microwave Digestion System and RAPTOR Microwave High Temperature Muffle Furnace, in Oct. 2005 to fully showcase its strong capability of research and innovation.

Among these products, EXCEL Microwave Digestion System was awarded as the New Product of 2006 by the Analytical Instrument Association of China Instrument and Control Society. In early 2007, the company launched APEX Atmospheric Pressure Microwave Synthesis & Extraction System and further strengthened its leading position in the Industry. Currently APEX is the only atmospheric pressure system that is integrated with special Industrial microwave cavity, fiber optical temperature sensor with closed loop feedback control.

In recent years, the company has been achieving a leaping advancement in all respects. In June 2004, PreeKem obtained the ISO 9001:2000 certificate. In the same year, PreeKem established branch offices in Beijing, Guangzhou and Chengdu successively providing prompt services to its domestic customers. Since early 2006, the company has been making its way into international market and has successfully sold its products to the countries and areas to cover Italy, Russia, Turkey, Japan, Australia, Korea, Taiwan, India, Iran, Pakistan and Thailand.
