What is the use of refractometer?
A refractometer is used to determine a concentration of a particular substance within a given solution. It operates based on the principle of refraction. When rays of light pass from one medium into another, they are bent either toward or away from a normal line between the two media.
What is SOP mode?
A standard operating procedure (SOP) is a set of step-by-step instructions compiled by an organization to help workers carry out routine operations. SOPs aim to achieve efficiency, quality output and uniformity of performance, while reducing miscommunication and failure to comply with industry regulations.
What does SOP research mean?
Standard Operating Procedures
Standard Operating Procedures (SOPs) are uniformly written procedures, with detailed instructions to record routine operations, processes and practices followed within a business organization. In clinical research, SOPs help define the group’s (e.g., unit, division, department, institution, etc.)
What is SOP in media?
Standard operating procedure of preparation, sterilization, storage and growth promotion test of solid and liquid media which are to be used for microbiological testing.
How does a Brix refractometer work?
The Brix Scale calibrates the number of grams of pure cane sugar (sucrose) contained in 100mL of water. A refractometer uses the refractive index to convert the raw Brix scale measurement into a weight percentage of sucrose content, and this displays as % Brix.
What is the unit of refractometer?
Refractometers measure the degree to which the light changes direction, called the angle of refraction. A refractometer takes the refraction angles and correlates them to refractive index (nD) values that have been established. Using these values, you can determine the concentrations of solutions.
What should I write in SOP?
Writing the Statement of Purpose
- Part 1: Introduce yourself, your interests and motivations.
- Part 2: Summarize your undergraduate and previous graduate career.
- Part 3: Discuss the relevance of your recent and current activities.
- Part 4: Elaborate on your academic interests.
How do I create a standard operating procedure template?
The steps in creating standard operating procedure template:
- First create an SOP template file.
- Then define the SOP format.
- Add common SOP elements.
- Finalize the SOP styles.
- Inform everybody about your new SOP template.
What is the difference between Brix and refractive index?
There is a direct relationship between the refractive index and BRIX. The measured refractive index is converted directly into weight percent sucrose content (°Brix). This conversion is based on ICUMSA (International Commission for Uniform Methods of Sugar Analysis).
What is the standard operating procedure for refractometer?
Standard operating procedure of Refractometer to determine the refractive index of liquid samples. To describe the procedure for operation and calibration of Refractometer. This SOP is applicable for operation and calibration of Refractometer.
How to make a sharp demarcation on a refractometer?
5.1.6 Adjust the eyepiece cross wire with a knob by rotating it in a clockwise or anti-clockwise direction so that the sharp demarcation line passes through its center. 5.1.7 Sharp demarcation is produced in the form of a circle having half light & half dark portion.
How to adjust the cross wire on a refractometer?
5.1.5 Allow the liquid to smear on the lower prism surface quickly close the prism lock. 5.1.6 Adjust the eyepiece cross wire with a knob by rotating it in a clockwise or anti-clockwise direction so that the sharp demarcation line passes through its center.
Where is the dividing line on a refractometer?
Turn the milled ring at the base of telescope clockwise or anticlockwise where colored band is illuminated and a sharp dividing line is seen. Which divides a field of view in half illuminated and a half dark position. By means of milled head screw, adjust the dividing line exactly at the intersection of the cross wire.
