Analytical Lab

ABOUT THE LABORATORY

This lab is dedicated to the chemical analysis of foodstuffs. Several advanced equipment is available, including nutrition facts analysis equipment, texture analyzer, and Aw meter.

Equipment Usability

  • KjelRoc Scrubber OPSISScrubbers are one of the primary devices that control gaseous emissions, especially acid gases.
  • KjelRoc Analyzer OPSISKjelRoc Analyzer is an automatic device integrating distillation and titration functions. It’s equipped with the latest core control system, powerful automatic degree and high-quality components, can easily achieve automatic distrillation, titration, and calculation.
  • Refrigerated Heating BathCooling and heating circulating baths are ideal for laboratory applications where a wide variety of temperature controls are needed. The reservoir in the circulating bath tempers samples along with integral pump that circulates fluid both internally and externally.
  • SocRox Extraction Unit OPSISSoxROC Extraction Unit is an automated hot solvent instrument that can extract fat according to official methods. The instrument is based on Randall and Twisselmann techniques, using hot solvent and a closed system to reduce extraction time versus manual Soxhlet.
  • HydRoc Hydrolysis Unit OPSISHydRoc Hydrolysis Unit is an acid hydrolysis system for fat determination according to Weibull-Stoldt. The complete digestion and filtration process runs in a closed system. The hazardous Hydrolysis process can now safely be performed with up to six samples simultaneously.
  • Fume HoodA laboratory fume hood is a type of ventilation system that primarily functions to provide personnel protection against toxic fumes, vapors and dust. Its secondary function includes protection against chemical spills, runaway reactions and fires by acting as a physical barrier.
  • HomogenizerA homogenizer is a piece of laboratory or industrial equipment used for the homogenization of various types of material, such as tissue, plant, food, soil, and many others
  • AW MeterA AW Meter is a device to measure the unbound water vapor pressures to determine microbial spoilage, chemical and physical stability.
  • Color readerColor reader is a device for measuring color and whiteness of foods or raw materials in paste, solid, or powder form
  • DigestorSoxROC Extraction Unit is an automated hot solvent instrument that can extract fat according to official methods. The instrument is based on Randall and Twisselmann techniques, using hot solvent and a closed system to reduce extraction time versus manual Soxhlet. The SoxROC follows officially approved methods for fat extraction.
  • Analytical BalanceAnalytical balances are highly sensitive lab instruments designed to accurately measure mass. Their readability has a range between 0.1mg - 0.01mg. Analytical balances have a draft shield or weighing chamber to prevent the very small samples from being affected by air currents.
  • Mini ChillerA chiller is a machine that removes heat from a liquid. This liquid can then be circulated through a heat exchanger to cool equipment.
  • Rotary EvaporatorThe purpose of the rotovap is to remove low boiling organic chemicals, usually solvents, from a mixture of compounds. The rotary evaporator is the method of choice for solvent removal in the modern organic laboratory. The solvents or low boiling compounds are removed by a simple distillation. The rotovap is designed to be operated under a vacuum (to lower a compound's boiling point) while heating the sample at the same time. A condenser is used to condense the vapors to a liquid, which are trapped in a separate flask.
  • FurnaceFurnace is used for determine the amount of non-combustible and non-volatile (ash) material in a sample. To determine the ash quantity, a sample is placed in the furnace and exposed to high temperatures (typically up to 1,100°C) for a given period of time. The combustible and volatile material in the sample is burned off and removed from the furnace, typically as gas.
  • Hotplate stirrerHot plate stirrer / hot plate magnetic stirrer keeps liquids circulating as they are heated for a faster, more even reaction. They are very useful when you need to mix component, either solids or liquids and get a homogeneous liquid mixture while heating.
