SER 148 Series - Solvent Extractors

Solvent extraction system suitable for the separation of a substance or a group of elements from solid and semi-solid samples according to the Randall technique.

The reliable solution for solvent extraction

The SER 148/3 and SER 148/6 can be used to separate a substance or a group of elements from solid and semi-solid samples according to the Randall technique (consisting of Immersion, washing and solvent Recovery).

As for the automatic version SER 158, the main field of application is the determination of the content of soluble products such as fats, detergents, plasticizers and pesticides in food, animal feeds, detergents, rubber and plastic formulas, pharmaceutical products, soil.

The SER 148 Series is a semi-automatic solution with no compromises on operator safety (IP55) and solvent consumption also guaranteeing a limited cost per analysis.

Combined to HU6 Hydrolysis Unit, is possible to use the same crucibles to prevent any possible sample loss between the two units.

 

Randall Method, Faster Results

Perform single or multiple solvent extractions with Randall method, an improvement of Soxhlet technique, as hot solvents are used to speed up the analysis. In fact, the fast solubilization made by hot solvent permits a considerable reduction of the extraction time (approx. 90 minutes).

The extraction is made by immersion of the sample in the boiling  solvent, followed by a rinsing phase with cold solvent.

Maximum reproducibility is ensured, as well as a high recovery rate of the solvent used.

SER Series can be used with a wide range of sample types and with a variety of solvents, for increased flexibility.

HU 6 Hydrolysis Unit

Optimum solution for the acid/basic hydrolysis of food and feed samples prior to solvent extraction for total fat analysis.

Preliminary Hydrolysis for solvent extraction

The VELP Scientifica Hydrolysis Unit HU 6 is the ideal solution for the prior to solvent extraction for the determination of the total fat content, in order to free the fat molecules ready for extraction.

This procedure is required in a number of AOAC Official Methods to determine the fat content of food samples such as meat, cheese, seafood, chocolate, cereal flours, etc.
 
The HU 6 performs hydrolysis in complete safety and handles six samples at the same time in order to maximize productivity.

 

Fast and safe hydrolysis

The samples are heated in test-tubes in an aluminum heating block offering excellent thermal homogeneity. Hydrolysis is performed in an acidic environment (4N hydrochloric acid) and in some cases also in a basic environment (20% w/v ammonia) for about 60 minutes at a temperature of 170°C. The hydrolyzed sample is then filtered in a glass crucible and washed with warm deionized water to eliminate traces of hydrochloric acid.

The HU 6 is supplied with a vacuum pump that ensure safety thanks to the reduction of acid fumes.

The glass crucible containing the hydrolyzed and washed sample is oven dried before being placed in a desiccator. The crucible is then transferred directly to the SER 158 and SER 148 Solvent Extraction Unit avoiding any possible sample loss and ensuring improved accuracy of results.
