In scientific research and medical work, the accuracy of experimental results and the safety of clinical operations are inseparable from reliable sterilization. As a professional supplier of laboratory equipment and consumables, Welso's WLS-HD series of vertical pressure steam autoclave provide users with reliable sterilization solutions with efficient, stable, and safe performance.

Multiple Models to Meet Different Laboratory Needs

The WLS-HD series of vertical pressure steam autoclave offers a variety of capacities, ranging from 35L to 100L, to meet the needs of laboratories and medical institutions of varying sizes:

WLS-35HD: 35L, suitable for general use in small laboratories or scientific and educational institutions;

WLS-50HD: 50L, suitable for routine research and medium-volume sample processing;

WLS-75HD: 75L, suitable for high-frequency, large-volume sterilization;

WLS-100HD: 100L, ideal for large research institutes, hospitals, and food and chemical companies.

This wide range of options not only enhances the equipment's versatility but also reduces investment costs, allowing research and medical institutions to flexibly configure their equipment to meet their specific needs.

Core Technology Advantages

● High-Efficiency Sterilization Principle

A single-layer design, combined with downward exhaust, effectively displaces cold air and ensures uniform temperature distribution within the chamber.

Immersed electric heating elements directly heat the water source, rapidly generating high-pressure saturated steam for enhanced sterilization efficiency.

● Safe and Stable Sealing System

A cross-beam sealing structure provides durability and reliability.

Equipped with multiple pressure and temperature protection measures, it ensures both effective sterilization and safe operation.

● User-Friendly Operation

Electronic control for easy operation and intuitive parameter settings.

Select models support printing and drying functions, facilitating sterilization record keeping and immediate use of items after removal.

● Environmental and Economical

Distilled or purified water is recommended to prevent equipment damage or sterilization failure due to poor water quality.

No complex consumables are required, reducing long-term laboratory operating costs.

Analysis of working principle

The WLS-HD series is based on the principle of moisture and heat sterilization.

In the closed sterilization chamber, the electric heater heats the water until it boils, quickly generating saturated steam. Under high temperature and high pressure conditions, steam can not only destroy the cell wall and membrane of microorganisms, but also cause cellular proteins to irreversibly denaturate and solidify, ultimately causing microorganisms to die. Compared with dry heat sterilization, wet heat sterilization has strong penetration and higher efficiency, and is particularly suitable for sterilization of liquid culture media, glassware, instruments and dressings.

Wide range of applications

The Welso WLS-HD series is widely used in:

● Medical institutions: sterilization treatment of surgical instruments, dressings, syringes, infusion devices, etc.;

● Research institute: sterilization preparation of culture medium, glassware and experimental consumables;

● Food and chemical enterprises: disinfection of experimental containers, solutions, etc. used during production;

● College laboratories: Daily experimental teaching and sterilization of research tools.

▲Warm reminder: This series of autoclave is not suitable for items that are afraid of heat and humidity, such as precision electronic equipment, oils, powders, etc.

Conditions of use

To ensure stable operation of the sterilizer, it is recommended to use it under the following conditions:

● Ambient temperature: +5℃~+40℃;

● Relative humidity: ≤85%RH;

● Atmospheric pressure: 70kPa~106kPa (the influence of local air pressure on parameters needs to be considered);

● Power supply: AC 220V±22V/50Hz or AC 380V±22V (the nameplate shall prevail).

In terms of water quality, Welso recommends the use of distilled water or purified water, which can not only ensure the sterilization effect but also extend the service life of the equipment.
