美國PSI(precision systems inc)
美國PSI精密儀器公司創始于1963年，從創立以來一直專注于冰點下降測量技術的研發和生產，在溶液，濃度，分子重量和化學分析的質量控制儀器制造方面有超過40年經驗，全線產品包括滲透壓儀，冰點儀和化學分析儀。PSI滲透壓和冰點儀采用冰點下降原理快速精確測量各種溶液的滲透壓值和冰點值,具有獨特的快速冷卻系統，全自動校準，操作簡單等特點，測量時間約為1分鐘，每小時可檢測40～60個樣品。


Precision Systems has been a leading designer and manufacturer of freezing point osmometers and cryoscopes for more than 40 years. Osmometers are used in determining the osmolality or total concentration of substances in solution. With a cryoscope, the measurement is the freezing point.

Our OSMETTE? and CRYETTE? families are found in applications in clinical labs, research, small animal testing, QC of pharmaceuticals, IV solutions, beverages, reagents, eye solutions, incoming product inspections, dairy, petroleum, for molecular weight determination, and many others.

We also designed and manufacture the ANALETTE? Open System Bench-Top Chemistry Analyzer for such applications as general purpose chemical analysis, drugs of abuse, physician-owned labs, quality control, pharmaceutical development, reagent development, industrial testing and many more.

 Precision Systems was founded over 40 years ago to design and manufacture freezing point osmometers and cryoscopes with superior precision, accuracy and reliability.

Precision Systems has pioneered technology in freezing point osmometry in many ways, including developing a simple, non-interactive calibration procedure used on all our instruments. We have led the market in offering the smallest sample osmometer available on the market at 10 μL. We also offer the most complete line of osmometers to meet every user's need. Our instruments are some of the most reliable on the market. We have customers calling about repair on instruments they have been using in their labs for 25 years or more.

Rapid cool-down of the instrument from turn-on, a straight-forward, two-step calibration process, a quick and easy test procedure, minimal need for calibration standards, low maintenance requirements and high reliability result in osmometers and cryoscopes that are low cost of ownership to the user over the lifetime of the instrument.

Our osmometers and cryoscopes are found in applications in clinical labs, research, small animal testing, QC of pharmaceuticals, IV solutions, beverages, reagents, eye solutions, incoming product inspections, dairy, petroleum, and many others.

We have carried the concept of low cost of ownership to our more recent product line our ANALETTE bench-top chemistry analyzers. These are open system, general chemistry analyzers, enabling the user to select the most appropriate reagent for the assay. By utilizing small amounts of reagent, but allowing the user to select the most cost-effective reagents for an assay, and by operating at throughput rates comparable to other analyzers at a fraction of the instrument cost, our ANALETTE is the lowest cost of ownership analyzer on the market.

Because of this unique characteristic, these analyzers are well-suited to such applications as general purpose chemical analysis, drugs of abuse, physician-owned labs, quality control, pharmaceutical development, reagent development, industrial testing and many more.

Most importantly, we are a customer-oriented company. Real people answer your calls and provide the highest service available. Please give us a call and let us help you with your lab's requirements.
