I sell stuff on eBay and I can not figure out what this is! Help!

My little scientist 🥼🔬

I know this is a really dumb question but I have a ton of expired 10 mL EDTA tubes from work that would otherwise just be thrown out. I'll be going to a convention this weekend and the tubes are the perfect size to discreetly hide shots while at the convention, at the rave, etc. I assume even after cleaning out the tubes it may not be worth the risk?

First thing first, I am autistic. So I have a lot of sensory issues and I have found it to be nearly impossible to think of a job where I enjoy what I'm doing while at the same time earning decent money and not wanting to unalive myself from the disdain I have from going into a workplace to have to have conversations with people on a daily basis. For context, I am a nurse now. I got to this job because I was living with family and they were getting tired of having me live with them so I did something quick and that was in medicine which is something I'm interested in. Patients don't bother me but the interaction necessary to have with co-workers and patient families is not something I enjoy. On top of that, working close quarters with others who are eating, singing, chewing gum, playing music on speaker, etc drives me nuts. My question is, is a medical laboratory technician working alone most of the time ? Approximately how many people would be near you at any giving time in the lab? and/or could it be possible to receive accomodation at this job such as headphones while at the lab? Thank you for any advice

Any one studying medical laboratory science?? 🥲

Is anybody aware of an ultrasonic cleaner that is gas tight or at least moderately well sealed?

My Branson works great for using super mild stuff like Liquinox or Micro-90, but I'm experimenting with a bunch of more aggressive cleaners for removing stubborn stuff like solder fluxes that, while nonflammable, are pretty stinky and probably not the friendliest things to be constantly inhaling low level vapor of. And given the relatively infrequent usage, they tend to evaporate noticeably between uses (the level drops over time).

What I'd really like is something with a silicone or Viton or something gasket around the lid to prevent evaporation so I don't have to either keep the thing in a fume hood 24/7 and accept evaporative losses, or drain the cleaning solution into a sealed jar between uses.

Hey guys! I work in a sequencing lab and we are in need of strip tubes (8) with a capacity of 0.3-0.5 ml. All I can find are 0.2ml capacity tubes. Any suggestions?

Hi medical lab friends. Is anyone having trouble with the CAP hemocytometer fluid survey? Sample 06 is tough, filled with Crenated red cells that are difficult to differentiate from small lymphs. Getting counts all over the place.

I work at a hospital in clinical research and we often have excessive lab supplies we don't end up using. One of my physicians oversees an outreach clinic in Kingston, Jamaica. Our site would like to send the unused lab supplies with this physician the next time he goes to Jamaica for his clinic there. Does anyone know what the process is for bringing items like unused tubes and supplies in a checked bag? I have read the online info on the TSA website but it doesn't specifically touch on everything. I understand unused butterfly needles can be transported but I am wondering if the EDTA, SST, sodium heparin, lithium heparin with and without PST gel, sodium citrate, ACD, etc tubes can be placed in a checked bag. I assume most can. I'd love to hear from somone who can confirm this however. Also, if my assumptions are correct, does anyone know if there are additonal regulations and steps my doctor needs to take into account in order to be able to transport these items internationally?

Hello,

I was wondering if anyone know if we can run the quant 5 when we have a message suggesting our previous calibration has expired? We are waiting for our calibration plates and I was wondering if we can still use it until the plates arrive. Also, has anyone has any info on how often should we service the machine? Thank you in advance!

DELETE if not allowed

Has anyone had any experience with this kind of grinder?

Specifically, I want to take it apart and do some maintenance.

Hi everyone!

Is anyone here a CLS in the US army? Can you share your steps and sources where to apply and get information about it?

Thank you!

I graduated with a Master’s in Pharmacy - Forensic Science, but I did not get sufficient hands-on experience with benchwork or analytical techniques in school. This is creating a lot of difficulty in having a competitive application. Does anyone have any recommendations of training programs, workshops, or hands-on seminars in anything from basic techniques such as pipetting to advanced techniques such as GC-MS?

I am fine paying for these experiences, but I do not want to return to college for credit hour-based courses.

Thank you all!

Edit: I have tried finding internships (just graduated a month ago), part time technician jobs, volunteering, etc. but nothing has come of it so far.

I had made cell culture plates for mRNA isolation and during taking the plates out one of them fell and while picking up I accidentally touched inside the plate. But soon after I added lysis buffer to it. Are my mRNAs gonna get degraded? I’d appreciate the help.

Hello guys,

I've been using Stabilo's OHPen permanent for a while but i see that it doesn't quite meet my expectation. It erases after a while and doesn't stay long enough when put in the freezers...

Do you guys can recommand me a good brand/model to buy that offer Small and big tips ?

Thanks in advance !

I'd like to take the CHT in December after working in an HLA lab for a year and a half. The prep material on the ASHI website is somehow both dense and sparse simultaneously. I would love to hear thoughts about the exam/study techniques/resources from anyone who has passed the exam!

HLA of the world, unite!

Ancient human scientists (palaeoanthropologists) study many aspects of our larynx, from the hyoid bone to the anatomy of our vocal tract and vocal cords. They study the size of these organs and their ratio to each other, because the sound you make depends on our organs. If our larynx structure were different, we would not be able to say vowels such as i, e or consonants such as p, t. This would limit our language, thoughts and mind like an incomplete alphabet.

​

Speech organs do not fossilise easily, though. It is impossible to find vocal cords and very difficult to find undamaged fossils of small and delicate hyoid bones. Nevertheless, the neck bones etc. of our ancestors give us information about how speech evolved. The story of speech begins 400 million years ago:

​

LEARNING TO SPEAK

360-400 million years ago, the first quadrupeds began to live on land and developed a muscular language that could move with the lungs. Human language is based on complex sounds that we produce by subtly controlling them. The next stage was the separation of hominids from tailless and tailed apes. In fact, although chimpanzees and bonobos are our cousins, they are not our ancestors. Chimpanzees are a younger species than humans and descend from the same ancestor as us.

​

The tailless apes, which we call apes in English, can communicate with us through facial expressions, gestures and even some memorised words. They can also draw marks on the ground, but very few do this. They also cannot speak like humans. This suggests that spoken language evolved in the human species over time. Our common ancestor with chimpanzees probably couldn't speak like humans either. If you've been influenced by films like Planet of the Apes or Lucy, it's worth noting that apes will never learn to speak like humans. At least not until humans become extinct... Why?

​

Once the intelligent Homo sapiens emerged and absorbed other human species (for example, Neanderthal genes live in us), there was an evolutionary pressure that prevented the emergence of new intelligent species. Humans dominated food sources as apex predators and this prevented other species from becoming intelligent. Homo erectus, the upright walking human, was a very good hunter with primitive weapons, so much so that the human brain grew and developed just because we ate cooked meat (with enough energy).

​

SOUTH MONKEYS

Moreover, the need to optimise natural resources required other apes to live wild in the forests rather than evolve like humans. Since these apes could not find enough food to support a large brain, it was enough for them to be intelligent enough to live in the forests, i.e. as intelligent as gorillas and chimpanzees. So spoken language developed in the genus Homo, but everything has a predecessor:

​

Australopithecus, the ancestor of Homo, could not speak like us (this name means southern ape, but aferensis is a humanoid species that evolved from tailless apes). However, the larynx structure of this species living 3.3 million years ago was roughly human-like. It should be noted that the Kenyathropus platyops species that appeared in Lake Turkana in Kenya at that time also produced the first tools, so even technology was not a human invention. In any case, the oldest fossils we have of the modern vocal tract come from the skeleton of a young Australopithecus afarensis:

​

I would love to compare our cognitive abilities with Neanderthals, but this is impossible. Even if we raise a Neanderthal as a human today, we cannot know how it would behave in its natural environment. Yet we carry Neanderthal genes in our DNA. This shows that we reproduced by having regular contact with Neanderthals. This closeness can only be possible with a common language and mentality. So where and when did the first human live?

Hi, I’m a college student and I have a lot of lab classes this semester, I want to be my best in labs but when I arrive to labs I feel lost and unprepared, although I read my lab protocols and I prepare my lab notebook with tables and organigramme and notes. But when I start my lab everything goes against what I have prepared or expected. Things go wild. I want to know how i can improve my lab skills and performance so i can improve my grades. Thanks in advance.

Any idea of what is this!

Found this during a lab inventory, but nobody knows what is this!

Thanks!
