Climatic and thermal chambers

Climatic chambers:

They allow you to control temperature and humidity, even light. They are used to reproduce precise climatic conditions, to simulate seasons, what happens at the bottom of a lake or under the ocean, etc.  They are also widely used for durability tests (ICH type in pharmacies for example). example ).

Ovens and ovens:

From the outside they are the same as climatic chambers, but in general they only control the temperature over larger ranges: for example up to 300°C for an oven and 2000°C for an oven.

Enclosures for extreme and standardized thermal tests:

This equipment is mainly used in the aeronautics, space, railway and automobile industries, to test the resistance of their finished products and components in extreme conditions. We can test for example;

-       The thermal shocks that a satellite undergoes when passing from the sun to the shadow: SJT, JIS, JB-T IEC60068

-       The dust resistance of an automobile component in the desert (IP55, IP65, etc. tests)

-       Its resistance to rain (tests according to IEC60526 IPx1, IPx2, IPx3, IPx4, IPx5 standards)

-      Or predict the lifespan of a part in a marine environment (salt fog): SWATT or SSC/CH tests

Grow enclosures:

Also called Phytotrons or illuminated incubators, by some researchers, these enclosures are particularly studied for carrying out tests on living things: small animals (drosophila, fish, crawling plants, rodents, etc.), crops, algae.

There are cabinet type enclosures (or “reach-in”) or culture chambers (“walk-in”) which have larger volumes with the same characteristics.

For living things, controlling temperature and humidity are important, but you really need help choosing the light and watering system, which are critical.

Particularly for plants and algae, you must decide whether you want to reproduce the external conditions (choose daylight instead) or accelerate their growth (mixture of blue and red).

The light spectrum chosen can be adapted to the types of plants or algae studied. The intensity of the source and the light density received by your test samples must also be specified (generally in micromoles/m2/s).

Special culture chambers are often necessary for vernalization, germination, plant pathology, and in-vitro culture.

Shaking incubators

Stirred incubators are used for testing on living organisms. They make it possible to carry out tests in parallel on numerous bottles in order to accelerate the research work and obtain the recipe which will then be passed into the pilot phase (scale-up) on fermenters or bioreactors of increasing sizes.

Agitation allows the environments to be aerated to provide the micro-organisms with the oxygen they need to develop quickly. It is most often orbital, but some shakers shake horizontally.

Stirred incubators control temperature, humidity, shaking speed, CO2 injection and light density.

Vacuum ovens

Vacuum ovens are often used to dry gently at a low temperature. They are, for example, used in watchmaking and industry to bond sensitive materials.

Incubators: with or without CO2, medical, hypoxia, anaerobic

Incubators are used in life sciences or in the food industry because they allow very fine control of the temperature to allow the controlled development of microorganisms. They are equipped with a double glass door so you can look inside without disturbing the samples too much. Versions with CO2 exist for certain tests. As well as medical versions used for human samples, particularly in hospital laboratories.

Anerobic or hypoxic incubators/enclosures allow tests on microorganisms that fear oxygen (such as bacteria from the digestive system). They limit cross-contamination and mortality of your samples

3. What parameters do you want to control? Which beach for everyone? What tolerance?

4. How much room do you need?

5. How many shelves? What are their dimensions? To be seen according to the quantity and dimensions of your samples

6. What maximum weight will you put on each shelf.

7. Do your products dissipate heat? How many Ws?

8. Do you need to remove a lot of humidity in the bedroom?

9. Do you do temperature cycles? What should be the temperature rise and fall speed? What will be the mass and thermal capacity of your samples (Kcal/°K/Kg). Linear ramp or not?

10. Should you control this speed over the entire range or just part of it?

11. What lighting do you want? Specify lighting on the top of each shelf? or on the side? Color - warm white, cold, blue, red...? Desired intensity: in Lumen, Lux or Micromoles/s/m2?

12. Is automatic watering required?

13. And other accessories: casters, cable passage, 2nd glass door, final ventilation adjustment for fragile samples, vertical or horizontal flow, CO2, Hypoxia, EN285 medical device, etc.

The 9 key questions to ask yourself when choosing the lighting for your samples;

What type of tests?

Do you need to replicate outdoor conditions? (a daylight spectrum is surely suitable)

Or rather promote (accelerate) a process? for example with “plant growth” spectrum with mixture of monochromatic red and blue LEDs.

Or even carry out standardized tests?

Very specialized room, or general?

If your room is allocated to only one type of plants, then we can advise you on the spectrum best suited to your needs.

On the other hand, if you need to test on a wide variety of species, then a “warm white” type spectrum will be preferable.

What type of lamps?

The question almost no longer arises to the extent that neon tubes are increasingly difficult to find as manufacturers replace them with LEDs which allow similar results to be obtained with a considerable expenditure of energy. lesser.

What intensity of lighting?

The intensity is ideally expressed in micromoles/m2/s useful for your plants. Or in Lux at a specified distance from the room. But the expression in PPFD is much more precise: see why further down in the “FAQ and Links” tab).

What spectrum?

The choice of spectrum is absolutely essential to maximize the development of your samples. Below you find several examples of choices of LED strips (and therefore spectrum) recommended by their manufacturers depending on the application

What uniformity?

This is the trick question. Ideally, any scientific approach should be based on the most homogeneous and reproducible tools possible. But having perfect uniformity has a high cost, in terms of investment because we have to add sources, then in use.

Very tight tolerances must therefore be reserved for very precise research.

Photoperiodicity?

Do you need to simulate a day/night alternation (or other)? Seasons? Do a multi-year search?

Should we fear certain pests?

The environment in which your plants will grow may contain pest larvae which can develop under the influence of temperature and light. Will these pests carry disease? Or will they slow down your process?

In this case, using a little UV may be beneficial. To be tested, because too much UV can also hinder the development of your plants.

Taking advantage of the Emerson Effect to boost growth?

The Emerson effect is the increase in the rate of photosynthesis after exposure of samples to light wavelengths of 670 nm (red light) and 700 nm (infra red).

When exposed to light of both wavelengths simultaneously, the rate of photosynthesis is much greater than the sum of the effects of red light and far-red light.

By adding our “laser diodes” it is possible to boost growth by 15 to 20%

Enclosures marked ATEX (for explosion-proof, or ExProof) meet very, very precise standards.

In fact, they are used to protect personnel and buildings against possible fires, or even explosions, during testing or storage of dangerous products.

If you are asked to use ATEX equipment, you will have to clearly define your risk class, because in the event of an accident your insurance will have no problem hiding behind complex regulations to slow down compensation.

Without claiming to be an expert in the field, we classify our ATEX speakers into 2 categories. The T range (ATEX type A) guarantees that a spark cannot enter the chamber to initiate a flame outbreak. The The X range is necessary

Once this simplistic categorization has been explained, it is necessary to go into more detail into the classes of risks linked to the laboratory environment and the products handled.

All ATEX devices are labeled with an ATEX code of the type:

ATEX II 2G Ex db eb h [ib] ib mb IIB T3 Gb

This technical rating explains for what type of application the enclosure is approved:

the "II" indicates the explosion group:

explosion group I: Electrical equipment for the exploitation of mines with a risk of firedamp, such as coal mining: coal dust, methane

explosion group II: Electrical equipment for all areas at risk of explosive atmosphere, except mines at risk of firedamp, such as the chemical industry: dyes, acetylene

the "2" indicates the type of explosion zone in which the device is located:

Zone 1 - (1G on the label) - if the dangerous atmosphere with risk of explosion is created permanently or for a long time (>1000h/year). No source of ignition must take place without a fault in the device, as well as in the event of rare or frequent failures.

Zone 2- (2G on the label) - if the dangerous atmosphere with risk of explosion is created occasionally (10-1000h/year). No source of ignition should take place without a fault in the device, as well as in the event of frequent failures.

Zone 3 - (3G on the label) - if the dangerous atmosphere with risk of explosion is created for less than 30 minutes per year. No source of ignition should take place without failure of the device, as well as in the event of frequent failures.

The G indicates use for Gas. The D dust

"Ex" indicates that the device is EEx approved according to CENELEC standards)

The lowercase letters that follow describe the types of electromechanical components used

“IIB” indicates the class of authorized gases

I for methane

AI for propane

IIB for ethylene (and similar gases)

IIC for hydrogen

The T3 indicates the temperature class

Or 200°C maximum allowed in T3
