What is the function of the substage condenser and how can it be regulated?
what is the function, and how can the substage condenser be regulated? Focuses the light on an small area above the stage; the iris diaphragm controls the amount o light entering the condenser.
What is the function of the iris diaphragm The substage condenser?
The iris diaphragm controls the amount of light passing through the slide or specimen, while the substage condenser focuses a cone of light on the slice or specimen.
What is the purpose of the condenser on a light microscope?
The condenser fulfills two functions in the microscope. It provides an area of evenly-illuminated light in the field of view at the specimen plane and illuminates the aperture of the objective uniformly with light of sufficient yet controllable angle.
Where is the substage of a microscope?
Substage Light- The substage light, located on the base of the microscope, passes light directly upward through the microscope. Light controls are located on the microscope base. Stage- The stage is the platform which a biologist uses to rest the slide on, which is the sample s/he is examining.
At what position should you keep your microscope substage condenser lens?
In general, at what position should you keep your microscope’s substage condenser lens? It should be kept half way between the body and the base.
How do you check that the condenser is in focus?
– Remove the eyepiece from the microscope and look down the tube. Close the iris diaphragm of the condenser to leave a field of view of about 4/5 of the diameter of the objective lens (see Fig. 4). If the object on the slide is obscuring the view then move it to a clear part without altering the focus.
How do you adjust a condenser?
When installing the microscope condenser, rotate the coarse focus knob (1) to move the stage to its highest position. Most compound light microscopes have a small knob (2) to raise and lower the condenser holder. Lower this holder so the condenser can slide into the holder below the stage.
What happens when the condenser is lowered and raised?
What happens when the condenser is lowered and raised? lowering the condenser causes less light to get to the specimen. A drop of immersion oil is used to help concentrate the light, otherwise the image will be too dark and blurred.
When should I adjust my condenser?
The adjustment of the condenser is especially important in setting up for correct Koehler Illumination, which is a technique used to provide even illumination and produce a sharper image.
What does the condenser do?
The function of the condenser in a refrigeration system is to transfer heat from the refrigerant to another medium, such as air and/or water. By rejecting heat, the gaseous refrigerant condenses to liquid inside the condenser.
What are the signs of a bad condenser?
3 Warning Signs You Have a Bad AC Condenser
- Loud and abnormal noises coming from the unit.
- Significantly reduced cooling capability from the unit.
- The unit is leaking a noticeable amount of fluid past the typical amount of condensation.
Can a car run without a condenser?
Yep, cars WILL RUN without a condenser (it’s really a capacitor) but the points will burn out faster! Electrical current will try to keep flowing when a switch (the points in this case) are opened so there will be an ‘arc’ across the points until they are open far enough to break the circuit.
What’s the difference between a compressor and a condenser?
The compressor “squeezes” the gas. It actually changes the gas refrigerant into a liquid, which is used throughout the A/C system to eventually produce cold air. The condenser is responsible for taking the pressurized gas from the compressor and changing it into a liquid vapor.
Is the compressor inside the condenser?
Both split air conditioner and heat pump condensers are made of the same basic parts. The condenser cabinet contains the condenser coil, a compressor, a fan, and various controls.
What does a compressor do in a condenser?
The compressor is responsible for moving the refrigerant between the evaporator and condenser coils, ensuring that the refrigerant changes to gas or liquid as needed. You can think of the compressor as the heart of the air conditioning system and the refrigerant as the blood.
How much does it cost to replace condenser?
Home AC Condenser Repair & Replacement Cost Repairing an air conditioner condenser costs an average of $150 to $1,000 or more. Replacing the entire coil runs $900 to $2,800. Labor alone makes up about half the fees. HVAC technicians charge anywhere from $50 to $150 per hour.
Can you replace just the condenser?
Your Condenser Unit Could Solely Be to Blame for a Broken AC A common question we get is if you can replace just the condenser. The short answer is yes, you can. Some technicians often do in some cases. Perhaps if you have a newer system and the damage occurred due to outside forces, such as inclement weather.
How long should a condenser last in a car?
Then, you end up with little cool air (or even no cool air) in your passenger compartment. Usually, though, you can expect that you will get 8-10 years of use from your AC compressor, and for many drivers, that essentially means the life of the car. So, what can cause an AC compressor to fail?
What causes a condenser to leak?
Perhaps the most common cause of a condenser coil leaking is the fact that the condenser is probably packed with dust, dirt, and debris. The next cause could be VOC’s, which is a term that stands for Volatile Organic Compounds.
What is the most popular cause of condenser leaks?
Not only is this a concern on it’s own, but it can lead to damage of other parts of your system. Leaks are most often caused by corrosion. One other factor that can create leaks in your condenser coil (especially ones with copper to aluminum connections) is vibration. Vibration can have many different sources.
How do you find a condenser leak?
One of the oldest ways to detect a leak is by using the bubble method. To do this, apply a soap solution to areas where you suspect a leak has occurred with a brush squeeze bottle or dauber. Typically, any escaping refrigerant produces bubbles at the leak points.
How do I know if my AC condenser is leaking?
Soap Bubble Detection All you need to do is mix up some soap with warm water. Then, you’ll need to mix this solution for several minutes. After it has been stirred up enough, send it through your AC refrigerant system. If there are leaks in your system, air bubbles will be visible.
How much does it cost to replace a AC condenser in a car?
To have the AC condenser replaced you will pay anywhere between $450 and $950, depending on where you go to have the work done and what kind of cars you have. The labor costs vary based on the kind of car you have, with prices starting at $130 and going up to $350. The parts will cost between $250 and $400.
What causes a car AC condenser to leak?
The first probable cause is that the condenser began leaking. There are seals on the part that leak with normal wear and tear. It’s also possible for the leakage to occur when physical damage stems from road debris or rocks. Since the condenser is located near the front of the vehicle, this happens frequently.
How do I know if my evaporator coil is leaking?
Signs of Damaged Evaporator Coil Components
- Air coming from the vents is warm.
- Air conditioner starts and stops frequently but doesn’t properly cool your home.
- Air conditioner does not turn on.
- Refrigerant leak near the indoor cooling system components.
- Unusual noises from the cooling system, such as banging or hissing.
Can evaporator coil leak be fixed?
The best choice to fix a leaking evaporator coil is a replacement, especially if it still under warranty. However, if this is not cost-effective for you at the moment, you can also try adding a sealant, which has about a 50/50 success rate.
How long do evaporator coils last?
10 to 15 years
