Description

A kind of conical flask with thermometric heat insulation function

Technical field

The utility model relates to a kind of chemical apparatuses, specifically a kind of conical flask with thermometric heat insulation function.

Background technology

Conical flask is the laboratory apparatus that chemical experiment is commonly used, and conical flask usually needs carrying out water-bath or heating on electric furnace, and existing conical flask is mostly monolayer bottles wall, and heat insulation effect is poor; And in heating process, often want control and measurement heating-up temperature, method conventional is at present that thermometer is hung on support, the other end stretches in conical flask, or adopt hand-held method, the method for hanging is stable not, particularly when the liquid boils, thermometer easily waves, hand-held, consume one's strength very much, cause measuring tempeature inaccurate, thus affect reaction effect; And the reactant in conical flask usually needs pH value determination, mostly adopt pH test paper, existing pH test paper colorimetric card, on paper box, usually can make moist, not be durable, and colorimetric cumbersome; Capitate bottle is usually used as titration vessel, but at present titration often needs manual operation, on the one hand easy overtitration, and on the other hand, titer is accurate, often to reckon metering by titration number of drops.

Utility model content

The purpose of this utility model is to provide the conical flask with thermometric heat insulation function that a kind of structure is simple, can realize accurate titration, can carry out pH colorimetric measurement fast, to solve the problem proposed in above-mentioned background technology.

For achieving the above object, the utility model provides following technical scheme:

Have a conical flask for thermometric heat insulation function, comprise bottle cap, bottleneck, body and titration outfit, described bottle cap and plug is located at the port position of bottleneck, and bottleneck and body are wholely set; Described body outside is provided with isolation insulation layer, isolation insulation layer offers multiple thermal vias, is provided with thermometer and pH compares vitta in the cavity between described isolation insulation layer and body; Described titration outfit comprise connect successively titration adding mouth, regulate chamber and spiral communicating pipe, chamber is regulated to be set to two, connected by capillary communication pipe between two adjustment chambeies, the other end of spiral communicating pipe is communicated with body bottom sides, and spiral communicating pipe is provided with control valve close to body place.

As further program of the utility model: the base of described isolation insulation layer is positioned at 10mm place, upside bottom body.

As the utility model further scheme: described thermometer is arranged along body direction, and thermometer is provided with mercury head and graduation of thermometer.

As the utility model further scheme: the internal diameter of described titration adding mouth is 5mm, two regulate chamber for ellipse and vertically arrange, and regulate chamber to have and regulate chamber scale, the internal diameter of capillary communication pipe and spiral communicating pipe is 2mm.

As the utility model further scheme: the described top of titration adding mouth and the top of body are positioned at same level.

Compared with prior art, the beneficial effects of the utility model are: the utility model, by the outer setting isolation insulation layer at traditional cone bottle, contributes to the insulation to reactant in conical flask, reduce the consumption to energy when being incubated; Arranging of thermal vias can prevent air heats in isolation insulation layer from expanding and isolation insulation layer is burst; By set temperature meter in isolation insulation layer, the quick temperature measurement to reactant in conical flask can be realized, without the need to hand-held or hanging, be convenient to reading, and thermometer not easily be smashed; Body is provided with pH than vitta, the pH value of reactant can be read fast according to pH than vitta after using pH test paper to measure the pH of reactant in conical flask, operate easier; Titration outfit adopts governor valve control titrating solution flow, can according to the consumption regulating chamber scale to read titrating solution accurately, more accurate, due to capillary communication pipe and spiral communicating pipe internal diameter tiny, and body and titration outfit connectivity part are provided with control valve, there will not be liquid reflux in body to enter the situation of titration outfit, avoid the situation of overtitration.
