Equipments required in a Laboratory

Equipments required in a Laboratory



1. Refractometer: It is used to measure the total soluble solids present in fruit juice and wines. Sugars are the major soluble solids in fruit juice and, therefore, total soluble solids (TSS) can be used as an estimate of sugar content. Organic acids, amino acids and soluble pectins also contribute to soluble solids. The refractometer measure the refractive index, which indicates how much a light beam will be refracted when it passes through the fruit juice or wine which is then correlated with TSS as degree brix.


2. Water Bath: It is used to heat samples and for Pasteurization process (in which samples are heated at 62.5 °C.


3. Hot air oven: It is used to dry samples. It contains one thermostat and 3-way heat switch. It has temperature range from 0 to 300°C. it is also used for sterilization of glass wares at temperature of 160°C for 1 hour.


4. Mettler Balance: it is type of weighing machine used for measuring chemicals.
