Tue, 10 Feb 2015 13:11:05 +0530 <p>The membrane filter technique is a substitute for the MPN technique and was introduced in the 1950s. The MPN is the procedure for analysing the water for any microbial presence. You can separate the bacterial colonies, when the MF technique is used. What made this better than MPN is that the latter could only tell you about the number of organisms present or the absence of them in the water. This very advantage made the <a href="">Membrane Filter Assembly</a>, to be accepted for testing any microbiological presence, absence and discretion in potable water. Furthermore, the membrane filter technique gathered a lot of audience because it allowed testing of a large amount of sample compared to any of the rival techniques. For presence of bacteria, 100 ml is the amount of water that is usually tested. The other techniques permit not more than 2 ml and at times, a few techniques let you to analyse only 0.5 ml. The system allows use of a filter funnel and a vacuum, and later the filter is replaced by a petri dish. This is a nutrient medium, which lets the organisms to grow and also helps in discretion of the bacterial colonies.</p> <p><br /><strong>Uses of Membrane Filter Technique:</strong></p> <ul> <li>E coli are the most commonly present microorganism, which contaminate the water and can even become life-threatening. This is why the water supplying plants keep a check on these and use the MF technology to get a solution for the contamination. </li> <li>Apart from the potable water supply by the government, this technique is also much used in the monitoring process of pharmacies, electronics and the cosmetics companies. </li> <li>There are various advantages of using the MF technique. One of the most appreciated benefits is that the preparation time is not very huge compared to the rest of the methods. </li> <li>This can be used on even very large volumes of samples. </li> <li>Isolation and listing of the colonies of bacteria found in the sample are possible with the MF technique.</li> <li>This is an effective technique, and lets one to remove the bacteria from the water.</li> </ul> <p><br /><strong>How to choose the apt company?</strong><br />You should be able to find various types of filtration assemblies. The filtration assembly with the joints and  rubber fittings are a few examples. Check for the various features offered, and the prices charged.

They can also be utilized for volumetric measuring if there are markings on the surface.</li> <li><strong>Heating</strong>: Reagents and samples can be heated while they are kept in Lab Glassware. Depending on the sample size and type of burner, different glassware can be selected. However, one must ensure that thermal expansion is uniform throughout the apparatus, in order to avoid fracturing.</li> <li>Filtering: Specialized glass apparatuses are used for filtration of solids, liquids and gases. They are fitted with fine membranes for dispersion of gases or collection of particles. At times there are valves attached to the filters for allowing or restricting the flow. </li> <li><strong>Vacuum </strong>and Negative Pressure: Scientific Laboratory Glassware, such as, bell jars are used for vacuum and negative pressure applications, as they maintain the atmospheric pressure and also give visibility to the components inside. Make sure that the glass is not etched, cracked, chipped or scratched; else it is likely to break under the pressure. </li> </ul> <p><br />Laboratory Glassware are very versatile in terms of their uses. However, not all apparatuses are suitable for all the processes. You must consult your <a href="">Lab Glassware Supplier</a> about the appropriateness of each equipment for different applications and also gain knowledge about their other significant features</p> Few Laboratory Apparatus and Their Uses Thu, 23 Apr 2015 10:18:04 +0530 <p>Laboratories are places with controlled conditions and equipment for conducting scientific and technological research in-order to make consistent advancements in the world of science and technology. Laboratories are also used for diagnosis of various diseases and viruses. So naturally there is a need of several Laboratory Apparatus for smooth running of the laboratory. Buchner Funnels, Sintered Filtered Disc, Vacuum Pin Tube, etc are some of the most important equipment in a laboratory.</p> <p> </p> <p><strong>Some Laboratory Apparatus and their Uses</strong></p> <ul> <li><strong>Buchner Funnels:</strong> They are basically used for filtration purposes in laboratories. Funnels made out of porcelain are mostly used but they are available in glass and plastic material as well. There are many advantages of using Buchner Funnels and one of them is that they make the filtration process quicker by draining out the solvent through the filter medium with the help of gravity. They are also used for collecting re-crystallized compounds in organic chemistry labs. </li> </ul> <ul> <li><strong>Membrane Filter Assemblies:</strong> They are used for various types of filtration purposes in laboratories and are available in different specifications in the market. </li> </ul> <ul> <li><strong>Laboratory Glassware: </strong>They are used in coarse filtration and gas dispersion. Different types of laboratory glassware are also used for general bacteria filtration and crystalline precipitate filtration. They are resistant to thermal shocks and any kind of corrosion caused due to acids and chemicals. </li> </ul> <ul> <li><strong>Viscometer Tubes: </strong>They are mostly used in research laboratories, petrochemical industries, oil companies, etc. They are normally used for measuring the viscosity of different types of fluids. </li> </ul> <ul> <li><strong>Vacuum Pin Tubes: </strong>Samples of metals like steel, gold, silver, etc are collected in their molten state with the help of Vacuum Pin Tubes for hydrogen analysis.</li> </ul> <p> </p> <p>Nowadays Sintered Glass Buchner Funnel and Fritted Glass Buchner Funnels are also available in the market. Fritted Glass Buchner Funnel Suppliers and <a href="">Sintered Glass Buchner Funnel Manufacturers in India</a> are known for their quality and dedication. Apart from Buchner Funnels they deal almost all kinds of Laboratory Apparatus.</p> Get pollution free with the new ideas Fri, 12 Jun 2015 11:32:18 +0530 <p>With so much pollution and adulteration in the atmosphere there is a need for a filter program that can filter any unwanted substance and produce almost clear and clean residue. Science has become the solution to all the problems and has got the answer to this issue too, which is called vacuum tubes. The micro-organisms are hard to detect and when mixed with minute particle, they are almost impossible to trace. Hence, vacuum filtration is used for filtering microbiological particles, and they involve analytical procedures that help in collecting minute particles (bacteria, precipitate, etc.) from a liquid suspension and have lots more to it. They are used to collect a sample from molten gold, steel and silver, etc., which is required for hydrogen analysis and all. <a href=""><strong>Vacuum Tube Manufacturers</strong></a> are now arising with grace in the commercial market.</p> <p> </p> <ul> <li>Best price for the best material</li> </ul> <p>The finest grade of borosil glasses are extensively used as they are resistant to harmful substances. The borosilicate filter flasks and silicone rubber stoppers are compatible with most filter holders. It is recommended to use flasks to collect filtrate or to act as a trap to prevent liquid from damaging pump or vacuum line. Suppliers across the globe supply a wide range of vacuum filter holders and accessories. The manufacturing companies come with high prices but get the work done in an efficient manner. The quality can be compromised when it comes to severe competition among the manufacturers, but then you need to check before finalizing one. Satisfaction of the clients should be the one and only motto of the companies. The companies do come up with products that satisfy your needs, and that is what is expected of them.</p> <p> </p> <ul> <li>The best of tubes</li> </ul> <p>There is no doubt that a number of manufacturers are there on the market, however,  only the best ones survive in here. The borosilicate material developed by them is a highly reliable product. With best manufacturers you get light weigh, thin up to 0.5mm approx. wall bulb section which is the weak point, as it breaks on contact with the molten metal. This is very much necessary and should be precise as after this breakage, the molten metal enters the tube to form a solid, slag free metal pin every time. These tubes are available on the market at attractive prices and there are lots of models to choose from.</p>
