Types of Chemistry Flasks

Types of Chemistry FlasksThere are actually a number of different types of chemistry flasks. Some are called punch down flasks, punch up flasks, pressurized flasks, and even acid-proof flasks. Which one you will want depends on what you are studying. If you are studying chemicals, then you will want to purchase a punch down flask that will be easily transferred from its container to your lab.A punch down flask is basically a short cylinder that is filled with powdered liquids. Once it is full, the stopper at the top of the cylinder is attached. When there is an increase in temperature, the stopper drops and the liquid inside the cylinder become liquid and then turn into gas when heated. The name comes from the fact that the stopper has to be punched down in order to let the liquid inside become liquid and then turn into gas. The amount of liquid it can hold depends on how hot it gets when the stopper falls.The Punch Down Flask is one of the most common types of flask. It can be fille d with organic solvents, a wide variety of chemicals, and other materials that can be used to create solutions for experiments. This flask is very easy to handle and carry, so you do not have to worry about spilling something inside. Other kinds of flasks like the pressurized flask are more for pure water solvents and chemicals, but they are also easier to handle and transport. The high pressure inside the flask can cause extreme heat and you can easily transfer it from the container to your lab.The Punch Up Flasks are used with water solvents, which can be toxic to some students. They are also used with chemicals that are harmful to the lungs and others that can cause skin allergies or chemical burns. The high pressures make them dangerous as well. These types of flasks are sometimes referred to as respiratory hazard flasks or chemical hazards flasks.Pressurized flasks are ideal for testing chemicals or materials that are a little too high to handle by hand. Most of these types of flasks are made of stainless steel, although other materials can be used as well. There are two types of flasks that have this style of opening. The first is called the flameless dispenser, and the second is called the flame top.If you want to get the right amount of oxygen into your hot work area, a flame-top flask is the way to go. Since it is open, there is always a flow of oxygen coming out and through the flask. It is not meant to be used by children. Most of these flasks come with air holes on the lid and an air filter.Oxygen bottles are another popular type of flask that most students use when doing experiments that will require a lot of oxygen. They can be used to test chemicals, which must have a certain level of oxygen in order to be safe for the experiment. You can also get a good deal of research done using flasks with oxygen that will contain some material that can be used to test things. Since a lot of research is now done in a lab environment, it makes sense to use a flask with oxygen instead of using a chemical to see if it can actually make something work.Lastly, some students may find that it is easier to use a type of flask called a non alcoholic gas. These types of flasks are nonvolatile and are usually used with nitrogen gases.

OFSTED may soon give Schools just over 2 hours notice - Tutor Hunt Blog

OFSTED may soon give Schools just over 2 hours notice OFSTED may soon give schools just over 2 hours notice before an inspection OFSTED may soon give schools just over 2 hours notice before an inspectionSchoolsI was a teacher for more than 15 years, and certainly have many fond memories of my time in the profession. What I remember most strongly though are when things weren`t going so smoothly. Perhaps it`s a feature the human condition, that the memories of happy events all tend to blur together, but more unsettling incidents stand out starkly. I only realised when I sat down to write this article that my strongest recollections are the periods of blind panic, the fear all the teaching staff felt when we were expecting a visit from Ofsted. The headmaster would summon us all into his office, each already knowing, by the faltering tone of his voice and his pale pallor, that the inspectors had informed him of their intention to inspect the school. I remember that we were always given two or three days notice - a grace period before Ofsted actually arrived. During these days we were all on overdrive: every aspect of the school was frantically attended to, with teachers doing their best to ensure all would be pristine and perfect by the time the people with their black folders arrived. I seem to remember we always did well, but the days before an inspection were hard ones indeed. In recent years the notice period has shrunk rather drastically, with ofsted typically informing a school in the afternoon that they plan to visit them the following day. I can`t imagine the pressure that must put teachers under, and can well imagine many of them spend the night in their classrooms, in order to ensure everything is ready for the inspectors in the morning. I`m certainly grateful that we always had a few days to ensure everything was put in order. There are rumours that ofsted are soon to shrink the notice period even further though, all the way down to a mere 150 minutes of warning time. That`s right, new plans indicate that a school will be contacted before 10am, and the inspectors will arrive sometime after 12:30am the very same day! If this had been the policy in some of the schools I worked in, the Headmaster wouldn`t have had to summon us into his office after receiving the red news, we could have deduced that `they` were coming by hearing his screams! Quite understandably there have been a number of people who are strongly against these new proposals. Mary Bousted, the National Education Union joint general secretary has said that the short notice period will put teachers under too much pressure: `Given the scale of change that Ofsted is proposing with its new framework I think it is only common courtesy for school leaders to be given at least 24 hours before visiting to give them time to prepare and collect their thoughts.` Ofsted have said that, even though they will arrive just few hours after first notifying the school, the inspection will not actually begin until the following day. I suspect that this will offer little comfort to teaching staff, knowing that the inspectors are hardly likely to overlook any anomalies they see during the first day. Also the senior leaders of the school will probably be required to accompany the inspectors the moment they arrive, thus impeding them from preparing for the full inspection later. Another issue of course is what happens if the headteacher is not present in the school the day the inspectors make their phonecall? The role of a headteacher is a complex and variegated one, and it is usual for them to working off site, perhaps meeting with members of the local council, or school governors at other locations during the week. Mary Bousted raised this issue, stressing that headteachers need to be present during an inspection, and that more notice period needs to be given: `This comes back to the problems that Ofsted has had when it has tried to bring in no notice inspections. There is a logistical problem about whether headteachers will be there to speak to.` `I think it also shows a lack of courtesy to school leaders who should be given time to prepare and collect their thoughts rather than getting a phone-call which says `We are coming to your school and you need to be ready to start talking about inspection`.` Of course schools need to be regularly inspected by an independent organisation - the vast majority are funded with taxpayers money, and the general public have a right to know that standards are being maintained. There needs to be a fair balance though - the inspectorate must be aware of the huge amount of pressure teachers are already under, and it would be unfair to compound this with their every working day being a potential inspection day. 14 months ago0Add a Comment

That said, you can eat a bit of milk bread and four squares of dark chocolate. Even pastries are quite calorific at around 120 calories each. In fact, you should just avoid all sw eet pastries.Forget about ice creams in summer and opt for low-calorie milkshakes.  Cakes and pies are also off the menu. If you fancy an apple pie, you might just want to have an apple instead. Of all the desserts, a flan is probably the least calorific.It’s recommended that you eat almonds if you’re hungry. While they’re quite calorific, they’re better for your health than the other things we mentioned. Hazelnuts are also a good choice. Around 100g of them have half as many calories as everything else we mentioned.If you prefer savoury snacks, you can have a bit of cheese. However, make sure it’s a low-calorie cheese. You can also have carrot and cucumber sticks. A slice of bread with hummus should also stave off hunger.You should also have green tea and water to drink throughout the day if you want to avoid snacking.Discover the best diets for sustained weight loss.A Light Dinner for Getting Rid of Extra WeightAvoid fish and meat for dinner and have something vegetarian . In fact, fish and meat are hard to digest and you run the risk of having a bad night. Since you're going to be going to bed shortly after dinner, don't eat too much. (Source: RitaE)Have potato, butternut squash, leek, carrot, or turnip soup or some lentils. You can have some slices of brown bread with boiled egg, too.You can have a vegetarian starter like a mushroom, spinach, or potato omelette with a salad.  For dessert, an apple should do the trick. You can also have yoghurt as long as it’s low in sugar and fat.  You can also have ginger, lemon, or cinnamon tea with it. These drinks are great in the winter. Don’t drink within an hour of going to bed as you’ll probably be up in the night going to the toilet.In any case, avoid heavy meals so that you can digest while you sleep. A bad night’s sleep can have negative effects on your body and lead to weight gain.So are you ready to give it a go?If you'd like to learn more about healthy eating, nutrition, and cooking, consider getting help from one of the many talented and experienced private tutors on Superprof. There are several different types of tutorials available but they all fall into one of three main categories: face-to-face tutorials, online tutorials, and group tutorials.Face-to-face tutorials take place between just the tutor and one student. This means that all the tutor's attention is on you. While this is great for ensuring that you learn quickly, it also comes at a cost. Outside of your tutorials, the tutor will be preparing and planning your lessons and will factor this extra time into their hourly rates. Face-to-face tutorials are usually the most costly type of tutorial but they're also usually the most effective.Online tutorials are similar to face-to-face tutorials as they have the same tutor-student ratio. However, your tutor won't be in the same place as you. Instead, they'll teach you remotely using a computer, webcam, and video conferencing software like Skype. Since the tutor doesn't have to travel to their students and can schedule more tutorials each week, they te nd to charge less than their face-to-face counterparts.Finally, group tutorials are between one tutor and several students. With each student paying for the tutor's time, these tend to work out as the cheapest per student per hour. Unfortunately, the tutor won't be able to tailor the tutorials or the course to each student.
