Using the cork borer, make 12 cylinders from your potato. Trim them with a knife until they are 3 cm long. Caution: be very careful with the cork borer and knife. Always cut away from yourself. Make sure there is no peel left on the core. (If a cork borer is not available, you may also cut strips of potato using a knife

A large potato tuber is first skinned and cut into a rectan­gular shape. A simple well is made at the centre of the tuber with the help of a cork borer and scalpel without piercing the other side. This potato osmoscope is then half-filled with 1 M sucrose solution; its level is marked with a pin and is placed in a petridish containing pure water •Cork borer. Diagram: Method: 1Collect the water and the separate sugar amounts of 1, 2, 3, and 4 teaspoons of sugar. 2Place each sugar amount in a different cup, leaving one without sugar. 3Fill all 5 cups with 150 mls of boiling water to dissolve the sugar. Clearly label each cup to recognise the amounts of sugar in each cup. 4Mix the sugar. Diagram B: Recommended sampling sites for pigs Diagram C: Recommended sampling sites for sheep 4.1.2. The samples are taken using a sterile cork borer (2.5 cm diameter) (Diagram D) or by cutting a slice of 5cm 2 and removal using a sterile scalpel and forceps (Diagram F). In either case the sample should have a maximum thickness of 2 mm 3. Insert the cork borer into a tap root piece (Fig. 2D) and take out the desired regions of root. 4. Put such a removed tap root piece in a sterile petridish and cut it transversely into small pieces as shown in (Fig. 2E). 5 Make sure that the potato is placed on a ceramic tile when using the cork borer - do not cut the potato cylinders towards your hand. Care must be taken when using the scalpel. Wear eye protection.

  1. 1 filter paper with a cork borer (ca 6mm diameter) or a hole punch. 5. When students are mixing the agar and the culture in the Petri dish, they should be instructed to swirl the contents gently a few times clockwise, anti-clockwise, forwards and sideways. Notes 1. Other suitable bacteria include e.g. Micrococcus luteus, Escherichi
  2. A vacuum flask (also known as a Dewar flask, Dewar bottle or thermos) is an insulating storage vessel that greatly lengthens the time over which its contents remain hotter or cooler than the flask's surroundings. Invented by Sir James Dewar in 1892, the vacuum flask consists of two flasks, placed one within the other and joined at the neck.The gap between the two flasks is partially evacuated.
  3. utes were as shown in the table below. In an investigation, a student extracted three pars of pawpaw cylinders using a cork borer
  4. Insert the tube, and reverse the cork borer. A 1 cm 3 graduated pipette could be used as the glass jet. The tip of the jet should be positioned so that it is in the center of the flask when the stopper is in place. About 20 cm of tube should protrude out of the flask (see the second diagram below)

  6. The starch agar was mixed, heated to sterilise it, then whilst still molten it was poured in a thick layer into sterile Petri dishes. After it set, it had 6 holes cut in it using a heat-sterilised cork borer, and the discs were removed aseptically, i.e. so as to reduce the likelihood of bacteria getting onto the agar
  7. A laboratory rubber stopper or a rubber bung or a rubber cork is mainly used in chemical laboratory in combination with flasks and test tube and also for fermentation in winery. Generally, in laboratory, the sizes of rubber stopper can be varied up to approximately 16 sizes and each of it is specific to certain type of container. As the rubber stopper is used in many experiment, some specific.

Diagram of the fixed-bed reactor used in the present study. The elements are not in scale. Five plugs, 8 mm in diameter were cut with a sterile cork-borer from the periphery of a 7-day-old colony of T. versicolor grown in PAM. The plugs were inoculated in a 250 mL Erlenmeyer flask containing 100 mL GYP and incubated on a Certomat rotary. Then, a hole with a diameter of 6 to 8 mm is punched aseptically with a sterile cork borer or a tip, and a volume (20-100 µL) of the antimicrobial agent or extract solution at desired concentration is introduced into the well. Then, agar plates are incubated under suitable conditions depending upon the test microorganism The diagram below shows a set-up for an experiment to demonstrate a certain physiology process. In an investigation, a student extracted three pars of pawpaw cylinders using a cork borer. The cylinders were cut back to 50mm lenth and placed in a beaker containing a solution. The results after 40 minutes were as shown in the table below 2. In both dishes, cut 4 equal size holes out of the agar using a 1.0 cm cork borer. (See next page for a diagram.) Keep the holes away from the end of the plate and at least 2 cm apart. Check to make sure the holes are cleanly cut with no nicks. Prepare a new hole if required. Check that the agar remains firmly stuck to the bottom of the dish

Diffusion is the movement of a substance from an area of high concentration to an area of low concentration due to random molecular motion. All atoms and molecules possess kinetic energy, which is the energy of movement. It is this kinetic energy that makes each atom or molecule vibrate and move around. (In fact, you can quantify the kinetic. Mitosis and Meiosis diagrams. Explain why the new embryos produced are a clone. 1. produced by mitosis; The students used a cork borer to cut cylinders from the carrot. Describe how the students should cut these cylinders to make sure that this was a fair test and would produce reliable results borer with a series of holes as shown in the diagram (fig. z), the large opening being just small enough to keep the pea from slipping through. This cork was then floated in a deep Petri-dish of distilled water, and as soon as the radicle had burst through the seed coats the peas were transferred to the cork Using the cork borer and forceps create 6 wells in the dish as shown in the diagram below. Position the lids so that the dots are at the top. Draw a straight line from the top to the bottom of the Petri dish lid as shown below Agar of both dilution and Cork borer techniques. The trial was done in triplicates.

cork borer (Fisher Scientific Catalog No. 07-845C) punch through the leaves to produce 100 leaf discs. Dislodge the discs from the cork borer with a clean metal wire, weigh and transfer the discs into Agdia's disposable sample extraction bags and extract in buffer according to the recommended ratios. The weight of the disc subsampling quickly, eg with a cork borer, and immersing the sample in the organic solvent as soon as possible. This is the most difficult step of the analysis for samples containing volatile hydrocarbons such as petrol, and the step which will probably lead to the greatest variation between laboratories Flipped learning lesson on this osmosis lab HERE: http://sciencesauceonline.com/bio/osmosis-lab/Follow me on Instagram: https://www.instagram.com/sciencesauc..

Reverse Made Easy: 5- through 7-inch diameter Grundomat horizontal boring tools are equipped with a new patented reverse mechanism. You can easily reverse the Grundomat during the bore, by adjusting a lever on the lubricator control system. There is no need to turn the air hose or stop the moling tool. Easily launched by hand or from cradle An increment borer is a T-shaped instrument composed of an augur, or a bit, and an extractor, which fits into the augur. The end of the T-shape is a handle, which you turn to drill in and out of the tree. The length of your increment borer should be at least 75% of the tree's diameter.

The Spotted Lanternfly (Lycorma delicatula) is native to China and was first detected in Pennsylvania in September 2014. Spotted lanternfly feeds on a wide range of fruit, ornamental and woody trees, with tree-of-heaven being one of the preferred hosts. Spotted lanternflies are invasive and can be spread long distances by people who move infested material or items containing egg masses Steroidal glycoalkaloids (SGAs) can be toxic to humans at more than 100 mg/100 g dry weight of potato tubers. The objective of the current study was to characterize phenotypically and genotypically a subset of 1750 ethyl methane sulfonate (EMS)-mutagenized diploid potato clones previously reported in our group for altered SGA production. The study reports on a wide range of SGA profiles in 246. A student investigated the effect of different sugar solutions on potato tissue.
