Manufacturing WATER ACTIVITY (Aw) since 1988

Food stability and shelf-life

What is AW?

The AW is an important measurement to maintain the chemical stability of foods, the microbiological stability of personal care products, to improve the shelf-life of a product, to predict which microorganisms will be sources of spoilage.

For example, most of the bacteria do not grow at water activities below

0.91 and molds which are the most tolerant of low water conditions grow in the range of 0.61 - 0.94.

This parameter helps in controlling the non-enzymatic reactions too.

Introduction to eFAst-Lab

Leak-proof measurement chamber

The unique design of the eFAst-Lab sensor can create

a leak-proof measurement chamber. A "pop" each time you open the head confirms this.

Volume ratio of air to product

The volume inside the eFAst-Lab head is very small

Temperature homogeneity

To obtain this the sample, the sensor and the chamber are kept at the same temperature in the eFAst-Lab

Constant temperature

The instrument can work at the same temperature using Peltier effect

Equilibrium time

The instrument determines automatically the equilibrium time

Automatic calibration

All the instruments need to be calibrated from time to time due to electronic derivation . Often this procedure is long and requires some knowledge. This is why GBX Scientific LTD has developed the first instrument to include the auto-calibration feature in 1 and 2 points without the need to tell to the instrument the value of the salt.

Dirty mirror info.

When using mirror technology, the mirror may become dirty due to contamination of products used. If when this happens you don't get the Dirty Mirror Info, you might obtain completely wrong measurements. GBX has developed a way to inform the user if the mirror needs to be cleaned. This can be done very easily in only 3 minutes.

Fullfill NF-ISO -18787 ( Dec 2017)

Your data are important for us.

So we are offering to save up to 30 years of data with 100 measurements/day

Thanks to our advanced technology, in case of issue with the electronic, the data are protected and can be retreive easily.

You can organise, too, to export automatically your data to *.csv format

Accurate measurement

accuracy of the measure +/- 0.003 from 0.0300 to 1.0000 of Aw

Resolution : 0.0001

Fast measurement

Thanks to a newly redesigned sensor, the response time is achieved in 2 to 5 min without the need to extrapolate the results. So the measure remains a true measure

eFAst-Lab almost no service

The sensor is based on cooled mirror technology. So it doesn't need to be regenerated every 6 months and often recalibrated.

CFR21 Part11

This water activity meter can be supplied with a CFR 21 Part 11 software .
