1. A chemical indicating composition, comprising an indicator; an organic silicone modified polymer; and a solvent; wherein, said indicator comprises a bismuth compound, a sulfur source, and a compound capable of generating alkaline conditions when exposed to steam at a high temperature. 2. The chemical indicating composition according to claim 1, wherein said .The autoclave is a device that can generate a controlled pressure and temperature environment. While several autoclave types are available, all consist primarily of three units: a pressure vessel, a heating/cooling system, and a control unit (Figure 18).The primary cost driver for autoclaves is the large capital investment needed to pass stringent pressure code regulations (Strong, 1989).

A wood sample (10 g) was placed in an airtight glass jar with 50 mL of distilled water and placed in an autoclave (Vapor Matic 770 Asal srl, Cernusco, Italy) for 20 min, at a temperature of 120 .Uniform corrosion was studied out of pile by long-time autoclave testing in pressurized water at 350°C (380 to 840 days) and in high pressure steam at 400°C (180 to 397 days). . {Influence of Chemical Composition on Uniform Corrosion of Zirconium-Base Alloys in Autoclave Tests}, author={Craig M. Eucken and Peter T. Finden and S. Trapp .Autoclave tape is an adhesive tape used in autoclaving (heating under high pressure with steam to sterilise) to indicate whether a specific temperature has been reached. [1] Autoclave tape works by changing color after exposure to temperatures commonly used in sterilization processes, typically 121°C in a steam autoclave. .
The image in Fig. 2 (a) illustrates a 316 stainless steel autoclave for laboratory applications after 20 cycles of heating treatment. The geometric data and parameters of the autoclave system have been reported in Table 1.These include the inner and outer radius, inner and outer height, flange thickness, and flange radius of the hydrothermal reactor. Physical and chemical properties of Asian sea bass (Lates calcarifer) backbone subjected to high pressure heating (autoclaving, 121ºC) for different times (30 min; AT-30; 60 min; AT-60; 90 min; AT-90) were studied.As heating time augmented, the increases in protein, α-amino group and hydroxyproline contents in liquor were attained, while hardness was declined .

Autoclave tape is a specialized tape product which is used on packages of materials placed in an autoclave. The tape has chemical strips sensitive to high heat and pressure which change color when they are exposed to sufficiently high heat and pressure, indicating that a package of materials has been in an autoclave.Complex media - media for which the exact chemical composition varies slightly from batch to batch. Defined media - a medium whose exact chemical composition is known. . An autoclave is typically used for sterilization of media. Define sterilization? Any contaminating bacteria introduced must be killed or removed.
