It's not that hard to open a hospital in another world, right?

Chapter 113 Thermometer, a guiding light!
Gretel threw the most tedious and boring daily preparation work to the new pharmacist, and happily, he plunged into the alchemy room.

The two are busy back to back.Ringer set up the distillation device and watched the condensed water fall into the container drop by drop. After making sure that he didn't need to keep an eye on it all the time, he slipped over to look at Gretel.

Startled as soon as it passed: Gretel squinted, holding a thin quill, and was marking a long glass tube.The glass tube was fixed on a wooden stand, and went straight down, with one end hanging in the boiling hot water.The water splashed, and the hot steam hit Gretel's face, but he didn't seem to notice it, and he concentrated on drawing the line.

In the center of the glass tube, a thin bright silver streak rises straight up.Gretel's nib landed on the bright silver end, pulled it horizontally, and then moved his footsteps to compare carefully.After observing for a long time, I finally breathed a sigh of relief:

"nailed it……"

Ringer asked curiously.Gretel unhooked the glass tube from the rack, laid it carefully flat, and drew a long line along the wall.Listening to Ringer's inquiry, he turned around happily:
"Make a thermometer!"

"Wen... what?"

"Thermometer!" Gretel's eyes sparkled.Whoops, it made his liver come out.Stuck in the hot studio, and the jewelry craftsman - small place, jewelry craftsman part-time glassblowing - seven or eight days, day and night!
Isn't it just a glass tube!On Taobao, one stick costs less than 10 yuan, and ten sticks costs 30 yuan, with free shipping and shipping insurance!In the end, he had to do everything by himself in this world-breaking world!
Heating, stretching, and pinching off—this step alone will waste countless glass tubes—reheating, fusing a short glass tube to it, heating and vacuuming it, and letting it absorb mercury.Turn it upside down, insert the lower part into the ice water, let it shrink to the bottom, heat and seal the top...

Fortunately, the inhalation of mercury is already the last step, and it is specially placed next door, and it is specially sedated with ice water.If he had worked rougher, the mercury vapor would have poisoned him, believe it or not!

"Thermometer? What is this for?" Ringo was at a loss.Gretel raised a bright smile:
"Indicate the temperature!"

Whoops, whether the body temperature is 37 degrees 5 or 38 degrees 3, I finally don't need to touch it with my hands...

Although a thermometer is not as good as a stethoscope or a sphygmomanometer, it can still be considered a useful clinical tool!Really, there are no tools, and it doesn't look right wherever the disease comes from!

"Well, you see, the mercury in the glass tube expands when it's hot, and contracts when it's cold. Look, I'm putting it in ice water now—is it down? Then put it in boiling water Here, he ascended again.

Different temperatures have different levels of mercury.We use this principle to indicate temperature.Hold the lower section and don't move, after a while, you can see the temperature of your fingers...""

The "useful thing" in Gretel's mind is like a small artifact in Ringer's eyes.He listened to Gretel's explanation, his eyes became brighter the more he listened, he held his breath, and stretched out his fingertips to pinch the mercury bubble of the thermometer.Gretel simply handed him the thermometer:

"Try it yourself, be careful not to put it on the fire, and don't break it. Don't bother me... Let me think about how a straight line is divided into 100 parts..."

Gretel threw himself on the table muttering, and began to scratch his scalp desperately, remembering how to draw the scale line.A murmur kept coming from behind:

"Expands when it's hot... shrinks when it's cold...expands when it's hot... shrinks when it's cold..."

Hey, uncle, you are very savvy!Thermometer or something, nothing else matters, only the four words of thermal expansion and cold contraction are the essence!Gretel smiled secretly, and raised his voice:
"Different substances have different boiling temperatures! You can try more. When doing distillation and extraction, use a thermometer to help control the temperature, and the efficiency will be higher!"

"yes?!"

Linger responded in surprise.Gretel didn't care about him anymore, he finished drawing the temperature line on his own, and turned his head to do the bacterial culture experiment.

The thermometer is not an expensive thing, as long as it doesn't get smashed, you can play with it casually.It's more important to do experiments. From time travel to now, he has accumulated a lot of subjects!
Finally, a coolie came to the door, and the most tedious things of making distilled water, making saline, and making alcohol were thrown out, so hurry up and do experiments!

Humming, Gretel arranged a stack of petri dishes on the table and put down the culture medium.Half of the Petri dish was filled with jelly and the other half with agar - thank goodness he finally got agarose...  

Next, spread out a roll of gauze, a ceramic spoon, a scalpel, and a piece of wood for a tongue depressor, wash your hands, and put your left hand up on the table——

"One, two, three! Magic trick - cleaning!"

The light of the magic trick, continuous, flashes over all the materials.

Gretel wiped all the experimental materials, including his own left fingers, on the two mediums respectively.

Next, take the same material that has been pasteurized and rub it on both media as well.Finally, wash your hands, disinfect them with alcohol, dry them, and carefully press the culture medium.

"Let me think about what I'm missing... By the way, cleanse the diet! Create water!"

Sewage treated with purified food and clean water produced by water-making techniques have been cultured for bacteria.Gretel labels each Petri dish, writing down the source of the sample and the time of cultivation.After doing this, he finally breathed a sigh of relief, and returned to his study to start writing his thesis:

""On the Sterilization Effects of Mage Techniques, Purifying Diet, and Water-making Techniques"...Well, let me think about whether I should go back to the Mage Tower and add the water from the water element pool to the comparison..."

boom! ! !
Suddenly there was a bang outside the door.Gretel's hand trembled, and a large drop of ink fell on the paper, which immediately stained the paper:

"What happened?"

Don't let there be a problem with the alchemy room!The still is still there!One cannot walk away!And downstairs, the disinfection room downstairs, the pressure cooker must not explode...

He rushed out desperately.In the opposite lounge, Priest Donald also rushed out holding the book.There was a series of footsteps on the stairs, and Ivan, Joanna, and Patrick who were reading in the consulting room, together with Little John sitting at the front desk, rushed up:

"what's wrong?"

"What happened?!"

"Little Gretel, are you all right?"

"I'm fine!" Gretel responded loudly.He followed the sound and rushed into the alchemy room opposite, and saw the new Ringer lying on the window, with half of his body leaning out of the window.Hearing the sound of Gretel's footsteps, he raised his black right hand tremblingly, tears streaming down his face, weeping and laughing:
"I broke through!——I broke through! I finally broke through to a level 1 mage, woo woo woo woo woo..."

So you made it up just now?Gretel rushed to him and looked down.The smell of gunpowder smoke in the air hadn't dissipated yet, and there was a black burn mark on the roof of the bungalow opposite the alchemy room, which was obviously burned by the flames just now.Gretel swayed under his feet, quickly took two steps back, and summoned a strong wind to blow away the smell:
"Ringer! If you break through, don't blow up the toilet!!!"

　　After checking the information, I found out that making a thermometer is very difficult... so difficult... Finally, I changed the plan and asked the protagonist not to make it himself, but asked him to find a jeweler to do it.As well as a routine sigh of modern industry, it really reduces the cost to a very low level.
　　For collections, for recommendations, for book reviews... for monthly passes...
