Essay about Good Laboratory Practices

The protein molecules in many foods provide the amino acid building blocks required by our own cells to produce new proteins. To determine whether a sample contains protein, a reagent called Biuret solution is used. Biuret solution contains copper ions. However, the chemical state of the copper ions in Biuret solution causes them to form a chemical complex with the peptide bonds between amino acids (when present), changing the color of the solution. Biuret solution is normally blue, but changes to pink when short peptides are present and to violet when long polypeptides are present.

The purpose of the lab was to determine the ratio of air to acetylene results in complete combustion of acetylene gas. The balanced chemical equation for this experiment was C2H2(g) + O2(g) --> CO2(g)+ H2O(l). Complete combustion is the reaction of an element or compound with oxygen to produce the most common oxides and energy. Complete combustion occurs when the fuel and oxygen combine in exact proportions to completely burn the fuel, which leaves a clean test tube. Incomplete combustion is the reaction of an element or compound with oxygen to produce some oxides with less oxygen than the most common oxides. Incomplete combustion occurs when there is not enough oxygen to react

Procedures and systems relevant to the prevention and control of infection are following companies’ policies and procedures which relate to correct hand washing procedure, wearing correct PPE for example gloves, aprons and protective clothing, the correct disposal of waste and using the correct cleaning equipment when cleaning spillages, surfaces, equipment, etc.

The general principals for environmental cleaning are to ensure the hospital environment is as clean as possible to reduce the risk of infection, and that all precautions are taken in accordance to legislation and Healthcare policy’s and guidelines. “To prevent the transfer of micro-organisms which may cause infection, and to prevent the transfer of foreign protein which may cause adverse reaction and pose the risk of spreading diseases e.g. vCJD. “

3. Experiment: Use the Gizmo to find the carrying capacity with Ample, Moderate, and Little land. List the carrying capacities below.

Sterilization is a heating system that prevents the spread of diseases. To run the steam sterilizer, the technician will need an attest pack. An attest pack is a steam plus a test pack. It is designed to routinely change the steam sterilization process in healthcare facilities. The attest pack is placed on the bottom of the sterilizer autoclave rack along with the instruments. Each test pack has a process indicator on the outside that changes from yellow to dark brown when it is steamed and processed. The indicator is incubated for three hours after sterilization is complete. This procedure is recorded and proves that the sterilization was not compromised. The steam sterilizer runs for one hour at a temperature of two hundred and seventy degrees

2. What are the four file types that can be used to save a snip using the Windows Snipping Tool?

Risk assessments are vital to be included within a laboratory setting as it involves evaluating the potential risks which may be involved when completing an experiment or activity. The employer must be aware that risks which someone is exposed to at work must be reduced by them responsibly implementing precautions in order to make the setting safer. They need to analyse: what could possible go wrong? How likely is it? And what would be the consequences? These questions are regularly used when creating a risk assessment so that every risk sheet has a similar outline and meets the criteria of an effective risk assessment. It covers the general procedures, the working environment and the handling, storage and transportation of various substances.

8. List three things that one can do to protect oneself from contamination/injury in the laboratory. (6

To conduct your laboratory exercises, use the Laboratory Manual that is available in the classroom. Laboratory exercises on your CD may not be updated.

groups. It was conducted to further the research in choice overload and paralysis of the mind.

Table 1 Concentration of protein, DNA, and ratio of the two in heart, kidney and liver of bos taurus. Average standard deviation of protein concentration is also shown.

This experiment can be enhanced in many ways. The amount of alcohol used as treatments could be lessened to measure the viability of A. salina more accurately. The amount of cysts in each Petri dish was not consistent because there

Throughout lab one we were introduced to many different forms of measurement, whether its using a ruler too measure length, a digital scale to measure weight, and also many different sized and shaped flasks to measure different volumes. Another key measurement of this lab was to teach the

Throughout the practical investigation, there were a variety of safety precautions implemented. This not only prevented physical injury, but allowed the efficient progress of the practical investigation in a safe manner.
