Under the urging of the new era,Hydrogen peroxide steam sterilizationBecome a domestic mainstream enterprise clean area inherent sterilization, in recent years, hydrogen peroxide steam is gradually spread, and it has been recognized by most cleaning experts and cleaning scholars.

So what is the difference between today's sterilization with decades?

Let us learn together.

Depending on the physical state, hydrogen peroxide sterilization can be distinguished into dry mist and steam sterilization.

Shot hydrogen peroxide

How does dry fog hydrogen peroxide apply?

The first is to dry the hydrogen peroxide liquid into a small particulate size liquid, which is seen at this time.

Steam hydrogen peroxide

Steam hydrogen peroxide is completely vaporized by flashing techniques.

Now the problem is coming, for the laboratory, pharmaceutical industry, research institutes, hospitals, animal rooms, troops, etc. User and groups that require sterilization of steam hydrogen peroxide, or dry fog hydrogen peroxide Is better bacteria?

Let's first take a look at several main parameters comparison.

project

Steam hydrogen peroxide sterilization, dry fog hydrogen peroxide sterilization data contrast.

First term: hydrogen peroxide form

Steam hydrogen peroxide sterilization:Steam hydrogen peroxideMolecular morphology, diameter10-10m Quantity, evenly distributed in each corner of the closed space, uniform sterilization.

Steak hydrogen peroxide sterilization:Presence with small droplets, diameter7.5 microns, 10-6m, need to compress air to apply pressure to the pressure storage tank, and cannot perform Brown movement (10-9M), uneven diffusion.

Note: Brown Movement: Brown Movement (Brownian Movement) Skinfales Demand. In 1827, the British botanist R. Brown was observed in the aqueous solution of pollen particles to a ruleless movement.

Second term: the reagent used

Steam hydrogen peroxide sterilization:35% volume ratio of hydrogen peroxide, 100 m3 is only 1L, low cost.

Steak hydrogen peroxide sterilization:4.5% peroxoacetic acid and 22% hydrogen peroxide, the rest are excipients and stabilizers. When using, it is necessary to add about 9 times the water to be added, diluted to a concentration of 0.5% peroxocetic acid and 2.5% hydrogen peroxide solution.

That is, the steam sterilization is low, which is low in sterilization, small size, and strong operability.

Section 4: Humidity requirements

Steam hydrogen peroxide sterilization:Automatic dehumidification

Steak hydrogen peroxide sterilization:Cannot dehumidification, require humidity50% or less

Article 5: Sterilization

Steam hydrogen peroxide sterilization:6-log

Steak hydrogen peroxide sterilization:4-log or 5-log, especially the room height, it is easy to reach the sterilization effect

Note: noteLog: A unit word.

Sixth item: Environmental protection and safety

Steam hydrogen peroxide sterilization:Hydrogen peroxide reaches sterilized effects in other strong oxidizing sterilizations, which can even repeatedly act on the room charged by the equipment.

It has been made for many years, and the compatibility study of the metal, resin floor, rubber, and electronic equipment has been conducted, and a complete compatibility report can be issued.

Steak hydrogen peroxide sterilization:simple alone2.5% of the disinfection effect of the hydrogen peroxide solution is small, and the actual work is still peroxoacetic acid. The disinfectant will quickly damage the human body and do not inhale.

Peroxic acid has strong erosion and influence on materials and equipment, even if it is very low concentration, it will cause a strong breaking ring, which will make epoxy floor bubbles.

Seventh item: reagent residue

Steam hydrogen peroxide sterilization:The hydrogen peroxide consumption is low, the decomposition needs to be short, and the remaining is automatically decomposed.H2O2, concentration \\u003c1 ppm

Steak hydrogen peroxide sterilization:Peroxic acid will result in residue in the contact surface- Acetic acid, which causes pollution and needs to be artificially removed.

Article 8:GMP application

Steam hydrogen peroxide sterilization:Process control, temperature and humidity, hydrogen peroxide concentration, consumption, pressure and other complete parameters monitoring, standard configurationA4 paper printer can chase the operation record, no need to copy, microcomputer storage and record sterilization conditions and processes, in line with GMP management requirements, complete 4Q and biological challenge report

Steak hydrogen peroxide sterilization:There is no process parameter control. There is no process parameter record. This system is unable to verify because there is no process control and monitoring. Different repetitiveness, relying on experience and manual calculation of reagents, do not meetGMP operation specification

It can be seen from the above comparison that steam hydrogen peroxide is sterilized to sterilize dry fog hydrogen peroxide, with the following advantages

Steam sterilization is low in dry fog, small size and strong operability.

Sterilization efficiency of broad spectrum

Complete security management features

Excellent process control
