What our customers say

The [Osmo1] is a valuable tool within our facility. The set up was extremely easy. There are a lot of features for programming if you require passwords for individual users or if you just want any lab personnel to be able to run a sample. ... . Maintenance is easy to perform, it is not time consuming, or something you need to dig out the manual for complex instructions. The supply pack has a sensor in it so when consumables need to be replaced it will auto-update the supplies and alert when supplies are >50...

Judy McCormick

Meno Ya Win Hospital

The Osmo1 is a wonderful instrument. You can rely on the results. When testing in duplicate the results are always within 2 of the original results. The analyzer is simple to use and maintain. I have used an analyzer like this for 15+ years and have never had an instrument related failure. Advanced Instruments offers the supplies that a medical laboratory scientist needs to perform linearities, quality controls, and set standards for this analyzer. ...

Advanced Instruments Osmo 1 Single [sample osmometer] is an exceptional product. It is user friendly and easy to train new employees and students. The user guide is extremely detailed and thorough and easy to follow along. The instrument is reliable and using only faults due to human error. Great product!

Lacey Campbell

Springhill Medical Center

We love our Osmo1 single [sample osmometer]. It's simple to calibrate, clean, and maintain. The precision and accuracy is much better [than] our previous Fiske 210 model and the Protinol and Renol controls are very stable.

Lacey Campbell

Springhill Medical Center

The Osmo1 osmometer is a very simple to use osmometer. The instrument is reliable, robust, accurate and very fast at collecting data. Our department have been using it for over a year and a half and I have never experienced any big issue with it. ... Overall, it is a high-quality instrument, accurate results, easy to use.

Haileab Ghebrekidan

Macrogenics

The Osmo1 follows in the footsteps of its predecessors like the 3250. The introduction of barcode scanning and touch screen has provided better functionality and connectivity. The device has rock solid performance and uses the same supplies as the 3250. Advanced Instruments is definitely the market leader when it comes to osmolality measurement with accurate results for patient clinical use in a 24/7 environment.

Ken Onuska

Halton Healthcare

I am the technical specialist for the area. The ease of use and small sample volume needed are what has impressed me the most [about the Osmo1]. Also, the programming ability. The team we deal with here in the Halifax area are exceptional and are always here to help in any way necessary. The instruments allow us to produce not only a quality result, but we do it the most efficient way possible.

Erica Mayo

NSHA

Great customer service, the FSE was knowledgeable and personable. The analyzer, which was an updated version of our previous osmometer, provides ease of use, updated technology, and produces accurate and reproducible results. The Osmo1 single sample micro osmometer makes maintaining regulatory compliance simple.

James DeGori

HNL Lab Medicine

The Osmo1 was very easy to set up. Instructions were easy to follow. I like that the printer is incorporated into the analyzer and that the consumable boxes have sensors that count down the number of tips left. Very easy for staff to use.
