Systec laboratory autoclaves series ELV are used wherever reproducible and safe sterilization processes and successful results are required – in research institutes, microbiological and quality control laboratories and in the food and pharmaceutical industries.

Sterilization applications

• Liquids such as nutrient media and buffer solutions
• Solid items such as pipettes, tubes, filters, glassware and plastic articles
• Waste sterilization

The right system for every type of sterilization

Fully automatic, microprocessor-controlled.

The various applications can be carried out using the autoclave’s standard programmes. Additional options ensure even more efficient work, with control of results and optimal, safe and reproducible sterilization processes.

Built-in technical progress

• Controlled steam release after sterilization to avoid overboiling of the liquid products
• Programmable start time
• Warming function to a presetable temperature of 25 – 80°C after sterilization
• Autofill for demineralised water
• Special cleaning programme
• Waste program with pulsed heat up for waste sterilization in waste bags to optimize air removal out of waste bags

Process control

Via state-of-the-art microprocessor technology

Programmes

6 individual programmes standard

LCT display

For pressure, temperature, time and errors

Sterilization parameters

Temperature and time are freely selectable; temperature can be set between 60 and 138°C. Sterilizing time can be set from 1 – 99 minutes. Preselected parameters remain programmed until altered.

Sterilization initiation

A PT 100 temperature sensor in a reference vessel guarantees that the set sterilization temperature is actually attained before sterilization starts.

RS 232 Interface

Demineralised water level regulation

Feed water for steam generation is automatically regulated.

Exhaust steam condensation

Exhaust steam is cooled down before leaving the autoclave. No unnecessary steam is exhausted. Drainage equipment protected from contact with steam.

Heat-resistant plastic covering on lid

Prevents contact with hot parts and protects from burning.

Pressure-dependent door lock

Prevents the door from being opened whilst under pressure.

Temperature-dependent door lock

In conjunction with temperature measurement in a reference vessel, the system prevents the door from being opened until the temperature is below a specified level. Hence preventing delayed boiling (as specified by technical regulations for pressure vessels, complies with British-and German Standards)

Door lock safety switch

Prevents the sterilization programme from being started if the door is not properly closed.

Water level safety device

Prevents the autoclave from being heated up if insufficient water is available for steam generation.

Excess temperature safety device

Switches off the heating elements if too high a temperature is attained.

Overpressure valve

Release of too high pressure.

Short batch times with intelligent technology

The actual sterilization time of e.g. 15 to 20 minutes at 121°C is only a fraction of the total time involved in the sterilization process.

Especially when sterilizing liquids, the heating and cooling phases are much longer.

State-of-the-art technology makes it possible to reduce the entire batch time considerably – several hours can be saved. In addition, this also means that media need not be exposed unduly long to high temperatures.

In conventional autoclaves, the prescribed temperature may well be reached in the vessel, but the liquids to be sterilized may only be at e.g. 100°C; the overall time required to attain equilibrium between vessel and liquid is hence much longer.

Up to 50 % less heating time – in all autoclaves!

This system is different! Due to the dual temperature and pressure control, the chamber pressure and hence temperature is increased in the heating phase. Temperature equilibrium is thus attained much more quickly and the overall sterilization time is shorter.

Up to 90 % less cooling time – optional!

The specially developed rapid cooling system – with or without support pressure – enables cooling time to be reduced by up to 90 %. This system can also be fitted retrospectively.
