ADVERTISEMENTS: Aim to study the working Principle and Operation of Equipment’s used in Microbiology Laboratory. A modern microbiology laboratory should be furnished with the following equipment. 1. Hot Air Oven for Sterilization: It is used for sterilization of glassware’s, such as test tubes, pipettes and petri dishes. Such dry sterilization is done only for glassware’s. […]

Apr 01, 2010 Weimin Sun Ph.D., ABMG, CGMB, CLSP(MB), in Molecular Diagnostics, 2010. Salting-Out Method. As an alternative to the phenol-chloroform extraction procedure, the salting-out method has the advantage of not using toxic chemicals. It is based on the principle that proteins and other cellular contaminants will precipitate in a saturated salt solution due to their …

Cold production (for cooling specific areas or producing chilled water). ... Let us consider a plant in which milk reception and pasteurization follow the pattern outlined in principle No. 1. ... the centrifuge separates whole milk into standardized milk and cream. The problem is therefore to share the original milk cost commitments for cooling ...

Dec 09, 2019 Centrifuge – There are two types of centrifuge used in RIA. Swing bucket rotator –capable of generating 1200-2500 rpm. The pallet is formed at the bottom of the test tube. Fixed angle head rotor – capable of generating 3500-4000 rpm The pallet is formed at an angle; Radioactive counters – there are two types of radioactive counters used ...

Feb 25, 2021 Agitation and stirring processes are used in all the chemical and biological laboratories in various shapes and sizes. Irrespective of the specific application or process that is being performed, the researchers or technicians need to use the best laboratory equipment for the job to make sure the results are consistent.

Fruit were stored at 0 0.5 C and 90 5 % relative humidity (RH) for 35 d followed by 21 1.0 C and 65 5 % to simulate shelf life for 4 d. During cold storage, weight loss and respiration rate were delayed by MAP. At the end of cold storage, higher firmness and acidity were measured in fruit treated with MAP compared to control.

Hot air ovens are electrical devices which use dry heat to sterilize.They were originally developed by Pasteur. Generally, they use a thermostat to control the temperature. Their double walled insulation keeps the heat in and conserves energy, the inner layer being a poor conductor and outer layer being metallic.There is also an air filled space in between to aid insulation.

Jul 01, 2021 ABO grouping is a test performed to determine an individual’s blood type.It is based on the premise that individuals have antigens on their red blood cells (RBCs) that correspond to the four main blood groups: A, B, O, and AB.. The purpose is to detect the presence or absence of A and B antigens on red cells by using Anti-A and anti-B antibodies …

Jul 13, 2016 Pour seeds (40-50 mg) into 1.5 ml centrifuge tubes. (See Figure 1 for appropriate seed volume, ~ 50 l). Label each tube with pencil (ink may fade away during sterilization). Place each labeled tube, cap open, into a desiccator 13. Place the desiccator in an active fume hood and close the desiccator's valve.

Mar 01, 2022 By applying the reduce, reuse, recycle principle, more than 96 percent of non-chemical waste, including polystyrene and shellfish, …

Mix vigorously, and centrifuge to collect contents to the bottom of the tubes, then put the tubes on ice. In a sterile nuclease-free microcentrifuge tube, mix the following reagents on ice. Each reaction contains: 1 μl of 5 μM of each primer, 10 μl of 2 iQ™ SYBR Green Supermix, and 7 μl of nuclease-free water (total 19 μl) (see Notes ...

Motion sickness occurs due to a difference between actual and expected motion. Symptoms commonly include nausea, vomiting, cold sweat, headache, dizziness, tiredness, loss of appetite, and increased salivation. Complications may rarely include dehydration, electrolyte problems, or a lower esophageal tear.. The cause of motion sickness is either real or perceived motion.

Source: WNA Nuclear Fuel Report 2019. The feedstock for enrichment consists of uranium hexafluoride (UF 6) from the conversion plant.Following enrichment two streams of UF 6 are formed: the enriched ‘product’ containing a higher concentration of U-235 which will be used to make nuclear fuel, and the ‘tails’ containing a lower concentration of U-235, and known as …

The principle behind Immunohistochemistry (IHC) entails detection of antigen or happens in cells of a tissue section by exploiting the principle of antibodies binding specifically to antigens in biological tissues. Learn more about this in this guide.

WHOLE BLOOD TO COMPONENTS. Blood component preparation was developed in 1960 to separate blood products from one unit whole blood by a specialised equipment called as refrigerated centrifuge.[] Preparing only PRBC and fresh frozen plasma (FFP) is by single-step heavy spin centrifugation; however preparing platelet concentrates (PLTCs), PRBC …
