1. Coke bottle instrument class production

Polyester plastic varieties, the market's most common and easily accessible is Coke, Sprite, mineral water filling bottles (hereinafter collectively referred to as Coke bottles). Coke bottle high transparency, good mechanical strength, good resistance to acid and alkali, easy to process. But poor heat resistance, heat immediately deformation contraction, high temperature flammable. Therefore, the Coke bottle is the production of simple non-heated chemical vessels of good materials.

1.1 The production of medicine spoon

The Coke bottle wall cut into about 100-150mm long, 30-40mm wide long strip, pressure set on the 10 × 150mm test tube, inserted into the 15 × 250mm large test tube (as shown in Figure 1), slightly heated back and forth on the alcohol lamp, cooled polyester strips and small test tubes withdrawn with scissors to trim polyester strips have been molded, and finally formed a medicine spoon. Finally a medicine spoon is formed.

1.2 Making a bell jar

Cut off the bottom of a Coke bottle, smooth the bottom, and add a rubber stopper to the top to make a bell jar, which can be used for experimental observation (as shown in Figure 2).

Figure 2?

1.3 The making of a wash bottle

A wash bottle can be made by adding a rubber stopper to the mouth of a Coke bottle and inserting one end of a long, sharp-nosed glass tube into a Coke bottle (as shown in Figure III).

1.4 The Making of a Funnel

The funnel is a common instrument used in secondary school chemistry experiments in filtration. A funnel can be made by stuffing the mouth of a small cola bottle with a ball of cotton wool and inserting a long glass tube upside down (as shown in Figure 4).

1.5 the production of explosion-proof cylinder

Hydrogen, chlorine, methane and air and other gas mixtures are easy to explode when ignited, the Coke bottle as a whole, cut a section in the middle, and then rolled into a diameter of 40-50mm cylinder, stapled, that is, into an explosion-proof cylinder to cover the outside of the mixture of gases, to prevent the explosion of the reaction (as shown in Figure 5).

1.6 production of protective eyewear

Secondary schools in developed countries and regions, university students in chemistry experiments are required to wear protective masks or protective goggles. Some areas of our country currently do not have such conditions, can be a Coke bottle (colorless) cut open, cut into the shape of the goggles, and then drilled on both sides of the small holes, with an elastic band linkage, you can wear the use of (as shown in Figure VI).

2. Plastic bottle device class production

Qipu generator is a secondary school chemistry experiments in the preparation of gases often used in the device, often can be used to produce H2, CO2 and other gases. Due to the large size of the Kip generator, mobile is not very convenient, the amount of reactants and more, can be completely around the use of plastic bottles to make a simple Kip generator instead. The following briefly introduces the reader to three kinds of plastic bottles to make the simple device.

2.1 device a key point of production: take 60ml plastic bottle, with a hot glass tube in the center of the bottle cap hot a diameter of 2.5mm round hole, the inner diameter of about 3.5mm long glass tube tightly inserted into the hole, and then set on the rubber tube, the bottle cap and the mouth of the bottle between the gap with the molten wax coated. In the plastic eye bottle with a wire iron many small

holes (as shown in Figure VII).

2.2 device two production points: take 60-100 ml plastic medicine bottle a (cut off the bottom), with a long conduit hose will be a round-necked bottle (as shown in Figure 8) assembled and wrapped in plastic window screen a small bag of zinc grains and other medicines, with a thick copper wire hanging and inserted into the hose. The production and suspension of gas is regulated by means of a stopcock.

Figure 8

2.3 device three production points: a plastic bottle of milk over the cap, the cap ironed a fine hole into a thick copper wire, the lower end of the tie a small plastic vial ironed with a small hole. The thick copper wire (coated with petroleum jelly) upward pull, hot holes in the small plastic vials and dilute sulfuric acid detachment, the reaction also stopped (as shown in Figure IX).
