RUDOLPH DENSITYMETER DDM RANGE: All the models of the DDM range are totally automatic, digital and have a built-in, touch-sensitive screen. They can control the temperature of the sample through electronic heating and cooling – Peltier method. The VideoView which is patented in the name of Rudolph comes with the basic unit. The entire U-tube is also scanned with a 10X camera. This ensures even the smallest bubbles to be magnified 10 times and the images are shown live in the screen. The range is between 0 – 3 g/cm3. The min volume of sample required is 1ml. The systems are equipped with 5 USB Ports, 2 RS232 Ports, Ehternet Port for Network Connection, Keyboard, Barcode Scanner, Mouse, Network capabilities.

They have a built-in 8GB Non-removable Compact Flast Internal Memory and the entire system would be driven by Embedded Win 7 OS. With calibration in one temperature the system works throughout the temperature range.

Models 2910 & 2911 can also be equipped with a 21CFR Part 11 module and it is easily enabled through the digital touch screen and come with either NIST or UKAS traceable standards.

The differences between the various models lie in the resolution, repeatability and accuracy.

Bibby offers a comprehensive range of hotplate stirrers.  The units are available in two sizes 16x16cm and 30x30cm. 30x30cm units have simple analogue control and are available with either a robust metal alloy surface or a chemically resistant ceramic one. The 16x16cm units are available with simple analogue control, digital control and there are also units that are analogue but can be controlled by a seperate temperature controller. All are available with metal or ceramic surfaces. There is also an infra red model, the CR302 which offers infra red heating rather than resistance elements, allowing for faster heating rates.

BRIX

 

Roughly speaking Brix is a scale which denotes sugar in distilled water weight/weight.  Actually speaking, Brix denotes the Sucrose in distilled water.  But we generally take it as total sugar dissolved in a liquid sample (juice for example) due to the fact that the other sugars are negligible.

 

This concept has found many takers in the soft drink industries where the Refractometer is used to find out Brix to control the sugar which is the costliest ingredient in an aerated drink or juice.

  

BRIX Vs. GELATIN

 

There is a known correlation between the Brix and the gelatin sol (colloidal suspension of very small solid particles in a liquid medium).  To arrive the gelatin concentration from Brix, one has to multiply the Brix value by 0.8.

 

For example if the Brix value was 20, then the gelatin would be 16% gelatin by weight.

 

The hand-held Brixmeters are a useful tool in the shop-floor of gelatin industries.

 

RIPENESS OF FRUITS THROUGH BRIX

 

The Ripeness of fruits is determined by the Brix value of its juice.

Brix is being used as a major factor to determine the harvest time. Mangoes and Grapes are two fruits where the Brix is being used widely to determine when they are to be harvested. This is due to the fact that they are commercial crops.

Brix in Grapes has more application as different types of wine demands Grapes with varied ripening levels.

There are also many NIR systems available in the market to determine the ripeness of fruits. They also use the data from a Brixmeter to build-up a robust calibration. The major problem with an NIR could be the different hues the fruits might take and this has to be factored in before we could have a decent correlation.

 

BRIX THROUGH RI & BRIX THROUGH DENSITY

 

Three samples were tested for Brix. Sample no. 1 was a commercially available Mango juice brand X, sample no. 2 was also a mango juice of brand Y and sample no. 3. Ravi brand Tea. The tea was mixed with milk and sugar. The samples were tested in hand-held Brixmeter and portable Densitymeter.

 

After some pondering, the following conjenctures were arrived at.

a) While the Hand-held Brixmeter finds out the Brix through RI, the portable Densitymeter finds out the Brix through the Density of the sample

b) While Brand X was a Mango juice, the Brand Y that we tested was Apple juice.

c) The reason why Ravi's tea showed such a big jump in Brix when tested out of Density was that the milk and the tea dust or leaves boiled in water have all added to its density apart from the sugar added.

REFRACTOMETERY ANALYSIS OF GLYCERINE

 

To find out the RI value of Glycerine; which is very much hygroscopic in nature through digital refrectometer its important that sample has to analyse at 20 Deg C and homogeneous temperature has to maintain through prism surface as well pressure (cover) for avoiding the fluctuation in RI readings.
