Iron frame use and precautions, iron frame use and precautions

Uses: 1. The iron frame is used to place and fix chemical reactions.

device, so that the reaction operation is safe and convenient.

2. According to different chemical reactions, iron rings and flasks that can move up and down can be arranged on the iron rod.

Clips, burettes.

Clamp, condenser tube.

Clamps, iron clips and other additional equipment.

3. If it needs to be heated, an alcohol lamp can be placed on the iron frame.

and other heating devices.

Precautions: 1. The iron frame is an iron product, equipped with iron rings and iron clamps of different sizes that move up and down to fix or place the reactor. The iron ring is divided into large and small, and the iron clamp has a flask clamp and a condenser tube clamp.

When clamping glass instruments, it is necessary to pad paper, cloth or rubber, and the tightness should be appropriate to avoid pinching.

2. The perpendicular line of the center of gravity of the iron frame equipped with the reactor shall not rotate or slide down.

Its hanging foot must be within the base to prevent tipping.

It is mainly used to fix test tubes, etc., and to prevent acid corrosion when used.

The iron frame table is often used to fix or place various instruments, and it has a variety of shaped products.

The iron frame is usually attached with 1 large and 1 small iron ring, 1 flask clamp, and 2 double clamps. Iron hoops are often used instead of funnel frames.

Precautions for use.

1) When fixing the instrument on the iron frame, it is generally carried out in the order from the bottom up. If you want to clamp the test tube with an iron clamp, it should be clamped near the nozzle. When fixing the flask, it should be clamped at the neck of the bottle and tightened appropriately.

2) The direction of the iron clamp and the iron ring should be consistent with the base of the iron frame to increase stability.

3) Avoid contact with acids and alkalis during use. If there is any inconvenience, it should be rinsed and wiped clean in time. The spiral should always be lubricated with a small amount of grease. Be sure to keep the rotation flexible and easy to use.

1. The iron frame is used to place the Zen slip and fix the chemical reaction device, so that the reaction operation is safe and convenient.

2. The iron frame is composed of an iron stable base and an iron rod perpendicular to the base and fixed on the iron base, according to different experimental contents, it is often equipped with additional instruments such as iron rings, flask clamps, burette clamps, condenser tube clamps and other instruments that can move up and down to place and fix the chemical reaction device, so that the reaction operation is safe and convenient.

3. Precautions for iron frames: the clamp and the iron clamp need to be used together, and the gap of the iron clamp and the iron ring should be upward. When clamping the glass instrument, it is necessary to pad the paper, cloth or rubber, the tightness should be moderate, and the screw should not be turned too hard, so as not to break the instrument.

It will not rotate or slide down. Pay attention to your center of gravity and avoid tipping. Pay attention to rust prevention.

When the instrument is clamped with an iron frame, it should be adjusted and fixed one by one from the bottom to the top.

1. Use: The iron frame is used to place and fix the chemical reaction device, so that the reaction operation is safe and convenient. According to different chemical reactions, additional instruments such as iron rings, flask clamps, burette clamps, condenser tube clamps, and iron clamps that can move up and down can be configured on the iron rod.

If heating is required, an alcohol lamp or other heating device can be placed on the iron frame.

2. Precautions: The iron frame is an iron product, equipped with an iron ring and iron clamp of different sizes that move up and down to touch the Zen macro, which is used to fix or place the reactor. The iron ring is divided into large and small, and the iron clamp has a flask clamp and a condenser tube clamp.

When clamping glass instruments, the joke book should be padded with paper, cloth or rubber, and the tension should be appropriate to avoid breaking. In order to prevent it from tipping over, the vertical line that does not rotate and slide down must pass through the center of gravity of the iron frame equipped with the reactor, and its vertical foot must be within the base to prevent it from tipping.

The function of the iron frame: 1. It is used to place and fix the chemical reaction device to make the reaction operation safe and convenient. 2. According to different chemical reactions, additional instruments such as iron rings, flask clamps, burette clamps and other instruments that can move up and down can be configured on the iron rod.

3. If heating is required, alcohol lamps and other heating devices can be placed on the iron frame.

The iron frame consists of a large base and an iron rod fixed to the iron base and perpendicular to the base. When clamping glassware on an iron frame, it is necessary to put paper between the clamp and the glassware to prevent it from breaking.

An iron frame is an iron product, equipped with an iron ring that moves up and down, of different sizes, and a Tiechaitan clamp to fix or place the reactor. The iron ring is divided into large and small, and the iron clamp has a flask clamp and a condenser tube clamp.

When clamping the glass instrument, use the pad paper, the tightness is moderate to avoid clamping, and the vertical line of the center of gravity of the iron frame equipped with the reactor shall pass through the vertical line of the center of gravity of the iron frame equipped with the reactor, and the vertical foot shall be within the base to prevent tipping.
