ETO Sterilizer

Ethylene oxide or ETO sterilizers are widely used in the pharmaceutical industry and health care institutions to sterilize products/materials sensitive to eto-sterilizermoisture or heat.
EtO sterilization is mainly used to sterilize pharmaceutical products that cannot support high temperature steam sterilization like devices and instruments that incorporate electronic components, plastic containers or plastic packaging. Pharmaceutical industry make use of varied sterilizers like CIP sytem or steam sterilizers. ETO sterilizer is one of the most popular pharmaceutical sterilizers.
What is Ethylene oxide?
Ethylene oxide or ETO is a chemical used in the pharma industry to sterilize medical devices. It is also used to make other chemicals. Ethylene oxide is colorless and considered a relatively toxic liquid and gas. It can be mixed in all proportions with water, ethers, alcohols, and other organic solvents.
ETO Sterilization in Pharmaceutical Industry
EtO gas filters packages as well as products to kill micro organisms that are left during production or packaging processes. This gas, mixed with air at a ratio of at least 3% EtO gas, forms an explosive mixture, potent in killing pathogens. Consisting of electrical heating jackets, these sterilizers provide excellent steam and temperature distribution in the heating chamber. The machines are also equipped with automatic temperature control mechanism, in which bacteria die from the coagulation or de-naturation of the protein constituents.
ETO Sterilization Process
A properly ETO sterilization equipment should be capable to handle every type of medical device and permeable packaging configuration. Most EtO sterilization process involves three different stages:
  • Pre conditioning
  • Sterilizer
  • Degasser

Applications of ETO Sterilizers
  • In hydration plants
  • In plywood industries
  • In food industries
  • In pharmaceutical products, hospitals etc.

SIP System

Steam in place system or SIP systems are widely used pharmaceutical sterilizers. Safety is of utmost concern in the pharmaceutical industry. All products are manufactured under strict aseptic conditions in compliance with statutory requirements.
Steam-in-place or SIP system is widely used for in-line sterilization of various processing equipments. It is one of the most popular sterilization system used in the pharma industry.
The SIP Process
One of the most widely used methods for creating a sterile environment in pharmaceuticals manufacturing is the use of heat in the form of steam to get rid of unwanted organisms. Though there are other methods of sterilization done by dry heat sterilizers or ETO sterilizers, recently CIP and SIP methods have become very popular. Steam-In-Place (SIP) is a sterilization method that involves sterilizing by way of steaming the interior of vessels, pipes, process equipment, and associated fittings, without disassembly.
Importance of SIP System
 The process of manufacturing and handling various pharmaceutical solutions and mixtures lead to cleaning and sterilizing these equipments regularly as they are susceptible to contamination. Proper SIP integration with pharmaceutical equipment is very important for the overall success of the operation. SIP is used for the in-line sterilization of vessels, valves, process lines, filter assemblies etc.
  • SIP provides a very effective, convenient and above all a safe form of sterilization.
  • The steaming system is easy to automate and validate.
  • SIP relies on the reduction of manipulations and aseptic connections that might compromise the integrity of pharmaceutical processing.
  • The specific components include pressure regulators, steam traps, and sterilizing vent filters to remove air and condensate, and to cool down, dry, and maintain the sterility of the pharmaceutical equipment following sterilization.
Application of SIP System
  • Pharmaceutical Industry
  • Dairy Industry
  • Beverage Industry
  • Biotechnology Industry

Dry Heat Sterilizer

Dry heat sterilizers are one of the most popular pharmceutical sterilizers. One of the earliest forms of sterilization practiced, dry heat sterilization, as the name dry-heat-sterilizerssuggests uses hot air that is either free from water vapour, or has very little of it and it doesnot play any role in the process of sterilization.
Dry Heat Sterilization in Pharmaceutical Industry
Dry heat sterilizers are mainly used for sterilizing various pharmaceutical products including ampoules, injection bottles, infusion bottles and production equipment. These sterilizers use dry heat and are better than the steam sterilizers in the sense that the process does not corrode the machine.This is also used to sterilize liquids with low moisture content and also for treatment of medicated powders. The process completely destructs all micro-organisms and does not cause any environmental pollution or inconvenience to humans. Usually made of stainless steel, the shape and position of heating elements in the chamber ensure uniform temperature distribution. The entire process includes drying, heating, sterilizing and cooling phase.

Dry Heat Sterilization Process
  • Place pharmaceutical instruments and items in the oven, and start the oven as per the designated temperature. The oven must has a temperature gauge or thermometer to ensure the designated temperature is reached.
  • The machine cleans, decontaminates, dries all instruments and other items to be sterilized.
  • Leave items in the sterilizer to cool before removing. When they are cool, the items need to be removed using sterile pickups and used or stored immediately. Proper storage is as important as the sterilization process itself.
Maintenance of Dry Heat Ovens
Maintenance of dry-heat ovens should alwyad be an integral part of every dry heat sterilization procedure. It is ti be noted that sterilization will not be achieved if the ovens do not reach the correct temperature .  Make sure:
  • That your oven is kept clean at all times.
  • Check the temperature gauge on a regular basis so that it is working properly. This can be done by putting a thermometer in the oven and comparing the temperature reading with the one on the gauge.
Application of Dry Heat Sterilizers
  • Sterilizing Laboratory Instruments
  • Sterilizing Ampoules
  • Sterilizing Injection Bottles
  • Sterilizing Pharmaceutical Vessels and Containers
  • Sterilizing medical instruments

Pharmaceutical Boilers

A boiler is actually a closed vessel in which water or other fluid is heated for the required purpose. The heated or vaporized fluid exits out of the boiler for use in various processes or heating applications. These pharmaceutical boilers are popularly known as steam boilers. Pharmaceutical boilers are steam generating systems used in various types of pharmaceutical and other applications.
Working of Pharmaceutical Boilers
This steam generating device consists of two principal parts: A furnace for providing heat by burning fuel or using electricity and a unit for converting water into steam. The steam is recirculated from the boiler for different heating applications. However the functioning of boilers is different from steam sterilizers or SIP sytem which are used for sterilzation process.
Types of Boilers
When it comes to the selection of a boiler, it is mainly dependent on the characteristics of the available fuel, the specified heating output, the location where it will be installed, the required emissions controls and many other factors. Boilers that are commonly used in the pharmaceutical industry are
  • Water Tube Boilers
  • Smoke Tube Boilers
  • Coil Boiler
  • Superheaters
  • Economisers
Advantages of Steam Boilers
  • Low steam disengagement velocity, with the ability to arrange the water tube furnace.
  • Flexible combustion space so as to incorporate the type of firing equipment, which is most suitable for a particular fuel and its application.
  • By constructing water wall furnace, less of refractory maintenance is required.
  • Quick steam rising is another advantage.
  • Provision of external furnace in steam boilers give sufficient volume for complete combustion of fuels like coal, oil, bio gas, wood bark, rice husk etc.
Features of Pharmaceutical Boilers
  • Usually almost all the branded pharmaceutical boilers are fully automatic
  • Maintenance clean combustion
  • The entire process is almost free of air pollutants.
Applications of Boilers
  • Pharmaceutical
  • Paper and Pulp
  • Chemicals
  • Food
  • Refineries

Magnetic Stirring Vessel

Magnetic Stirring Vessels or Magnetic stirrers are one of the most used magnetic mixer in pharmaceutical industry. The mixing equipment consists of an impeller, bearing, welding plate, drive unit and control box for efficient and high quality mixing of raw material and particles.
A magnetic stirrer consists of a small bar magnet, also known as stir bar; this plastic coated bar magnet is placed in a vessel for efficiently stirring liquids. The rapidly rotating magnetic field causes the bar magnet to spin at a high speed. Magnetic stirring vessels are preferred over motor driven stirrers as they are more efficient, have no moving parts that break down or wear out and are quieter. Being small in size, these stirrers are easy to maintain, clean and sterilize than other devices. As opposed to the motor driven stirrers, magnetic stirrers do not contaminate the vessel as they do not use any lubricants.

How Magnetic stirrer works:
The bar magnet is placed in a vessel containing liquid which is to be stirred. At the top of the stand, vessel is set in such a way, where the rapidly rotating magnetic field causes the bar magnet to rotate, which finally results in the stirring of the liquid. Because of its small size magnetic stirrer, this device is preferred in laboratory experiments.
Following types of magnetic stirrer are found in pharmaceutical industry:
  • Air Operated Turbine Magnetic Stirrer
  • Heavy-Duty Magnetic Stirrers
  • Magnetic Stirrer with Timer
  • Magnetic Mini Stirrer
Application of Magnetic Stirring Vessel:
  • Pharmaceutical
  • Chemical
  • Cosmetic
  • Magnetic stirrer is used in lab to work with different solutions.
  • The stirrers are beneficial to scientists.
