WebJun 18, 2024 · June 18, 2024. When chemists want to transfer a small amount of a pyrophoric reagent, such as tert-butyl lithium, they typically use a needle and syringe. … WebPurpose: The purpose of this lab is to synthesize Mo2(O2CCH3)4 and K4Mo2Cl8. Then obtain the IR spectrum for both the products to analyze for characteristics. Procedure: Week 1 1. Connect nitrogen source to the flask and connect the receiver flask to a bubbler 2. Insert one end of the cannula through the rubber septum on the source flask 3. Allow the …

WebA cannula (plural cannulae or cannulas) is a tubing that can be inserted into a reservoir or body (for medical uses), often for the delivery or removal of fluid. Lab cannula are a special type of tubing used in air-free synthesis chemistry to transfer air-sensitive liquids and solutions, though can also be used for transferring other liquids.

WebBiological Lab Techniques. Techniques used in Biology, Biochemistry, Chemistry, Molecular biology, etc. are called as Biological techniques. Few such techniques are Air-free technique, Air sensitivity, Cannula transfer, Glovebox, Schlenk flask, Schlenk line, Air-free techniques, Centrifugation, Flow cytometry, Polymerase chain reaction, … WebMar 2, 2024 · Polyolefins (POs) are the most abundant polymers. However, synthesis of PO-based block copolymers has only rarely been achieved. We aimed to synthesize various PO-based block copolymers by coordinative chain transfer polymerization (CCTP) followed by anionic polymerization in one-pot via conversion of the CCTP product … Cannula transfer or cannulation is a set of air-free techniques used with a Schlenk line, in transferring liquid or solution samples between reaction vessels via cannulae, avoiding atmospheric contamination. While the syringes are not the same as cannulae, the techniques remain relevant. Two methods … See more Septa Septa (singular: septum) are rubber stoppers which seal flasks or bottles. They give an airtight seal, preventing the ingress of the atmosphere, but are able to be pierced by sharp … See more This technique has been described with illustrated detail.
