Equipment

Not that I can contribute this, but I thought that it would be interesting to see the home/work labs that some of the people here use. It would help to see what other people in your field use and give you and idea of what you could use.

In this forum every piece of apparatus, devices, glassware, etc. can be discussed. Properties of the equipment, ways to make special equipment from standard products, creative use of standard products in a special way, all this kind of things can be discussed here. We do not appreciate threads with pointers to manufacturers of certain equipment, this is not meant to be a forum, filled with advertisements. There is no objection of mentioning a certain company, but it must be in the context of useful information about the device or apparatus being discussed. We would really love to see creative ideas of how the functionality of hard to obtain devices can be mimicked…

Good day, I hope im posting this in the right area.. it my first time making a post on the forum! I was wondering someone can enlighten me a bit on the following subject . I'm thinking of making a tube furnace for some lab work, as these things are way way to expensive to buy, and it should not be all that difficult to building one. I have seen a few ppl make tube furnaces using nichrome or kanthal wire (resistive heating), this is super simple, but this wire will need to be replaced every so often, so i was thinking a more permanent solution would be to use a induction coil to heat a graphite tube (used as heating element), with a inner ceramic tube that…

Our lab is experiencing a major issue with PCR results. We switched to a new lot of 96-well plates and suddenly started seeing rampant false signals causing QC failures. The specific product in question is the Agilent brand: Storage/reaction microplate, 96-well, polypropylene, 1 mL/round well, round bottoms, 32 mm height, irradiated. Part Number: 204357-100. Looking to see if any other lab out there is or has experienced a similar problem, especially specifically with this equipment.

Hi everyone, I'm a medical student, and we are conducting research, and we encountered a problem along the way. After some research, it led me here to this website. I've seen a similar question and have taken note of the answers provided by other members, such as GoPro and Borescope. I messaged the author of the post, but he/she was last active in 2018. I'm unsure if I will receive a response, but I'll remain hopeful. We are conducting research where we will grow fungi in our modified culture media. To facilitate fungal growth, we need to place it inside the Thermoline incubator for several days. Recording a video of the growth process would be beneficial since …

Hi everyone, I'm a student lab assistant assisting on an experiment and we're stuck on a particular problem which I thought maybe the collective wisdom of the great people here might be able to solve. We are doing an experiment where we are growing crickets inside a Thermoline Incubator with diurnal lighting. It would be really helpful if we can video record them inside the incubator throughout their life cycle from birth to adulthood. The incubator has a solid door so we can't point a camera into the incubator from the outside and the incubator is set to 32 degrees celsius / 90 degrees fahrenheit on the inside. We're contemplating putting a camera in the …

I am looking at building a device that makes it easier to stir or mix liquids together. Is there any advantages or disadvantages of Manual stirring Magnetic Stirring device that use a paddle to stir liquids (usually a motor of some sort) Or rotating the actual beaker so the liquid within moves around at a consistent speed. I have found by accident that the beaker I have here, sits nicely on a robot wheel, connected to a motor and Arduino, so if I can attach more securely should allow this to be set up while mixing. I will eventually add a potentiometer to this so that the speed can be controlled and maybe a few other components, such as a…

Hi all. Trying to find in the market a motorized mechanism that sweeps an angle of chosen magnitude; can be even a toy or toy part. There has to be something available. Ideas please ? Wheel W turns pushing and pulling a link L that moves forth and back a part continuosly sweeping an angle A. + are pivots. Varying radius R changes the angle A swept. There may be dozens of different approaches, sketches to produce the same.

Hello. I am looking for a cheap (ideally lower two digit price) digital thermometer with two or more decimal places for Kelvin/Celsius. It would be nice if the temperature value could be displayed live as a line on a Windows PC or Android device. It is not about high-end lab technology, but rather "Ali"/"Ebay"-. The accuracy is also not primarily important, I am only concerned about fluctuations. And the thermal sensor should not measure the temperature of an object, but only its own (thermocouple) temperature (in a heat-insulating material that protects against drafts). For scales, one-thousandth of a gram is common even for cheap products. Is ther…

I have just bought a burette, mostly so I can practice titration with water, but will hopefully move on to doing some science with this, it is a plastic 25ml. Before I start any hints / tips on keeping this in good condition, e.g make sure the tap stays working properly,. I have heard they can seize up, but not too sure. I am guessing cleaning should be a case of running water through. Thanks for any help I did search for this on the forum so will keep looking but any response should help others too. Regards Paul So from this is running a salt water solution through this better than perhaps, tap water or ideally de-ionised water. …

someone know where i can find agar to make agar plates to culture bacteria???

Hi everyone, I was wondering if there are any online resources you regularly use to track experiments, and your progress. Thanks in advance! Kevin.

This is a equipment made by me inorder to measure the turbity of the water this is made in a measuring jar and there will be a value corresponding to it, the point at which the marking disappear is noted and measured

I am looking for some sort of stand that can hold multiple 25mm diameter test tubes inside an ultrasonic tank. I would like to hold at least 4 test tubes, preferably 6. They must be held at the same height and be easily removable. Currently I have been using 2 heavy retort stands with 2 four pronged clamps per stand. This is a lot less than ideal because the clamps are held one above the other which does not work well because of the significant height difference. I would like something which works better, ideally without costing me large amounts of money. I would think that anyone with good experience in professional science might know of something which would fit my…

A compact disc has pits on its surface to represent the data bits. Is the optical surface of a CD smooth as a mirror when new and blank, before anything is recorded/'burned' ? Am after a small, light, thin, durable mirror if I can cut off from a new CD

Basically, because of current events, I've started doing a lot of amateur chemistry again. Although I already posess a reasonable amount of just basic glassware (beakers, erlenmeyers, volumetric flasks, yadayada), I really lack a lot of the glassware I can usually access. Kinda hard to do any organic chem without even being able to set up a reflux ;). Since I've been sort of out of the loop for a little while now, and things have really changed since I was a teen... Where do y'all buy glassware online nowadays? What type of source/place would you recommend for cheap/$hit tier glassware for potential sacrifices to the gods of chem and what places would you recomm…

How does foot orthoses work?

I have a microscope that doesent work it was fine when I got it but something happened and it lookes like there’s dust or water or bacteria or something inside the lens what do I do?

Hi, I'm no scientist. I'm here because I think someone reading this can help me with a problem I would like to resolve. I restore pottery and porcelain art and antiques. The method I use involves airbrushing small amounts of two-part epoxy paint to cover the repairs. Measuring out the two parts of epoxy (1:1 by volume or 3:1 by weight) is a slow and messy process and I am looking for a better method. Currently, I use the weight method and two eye droppers but the thick viscosity of the epoxy make measuring and mixing a slow and sticky job. There must be a cleaner, more efficient way to measure and mix these small (+/- 1/2 ounce) amounts. Any suggestions?

Does anyone know of a commercial hydro electric generator kit we could buy for tutorial purposes ?

I was recently gifted this defective heating mantle. It is like this one from ebay (looks the same) http://www.ebay.ca/itm/110-V-2000-ML-Capacity-Heating-Mantle-Free-DHL-Shipping-by-Quality-Brand-BASCO/282118501134 Anyway, cheap garbage no doubt, so I tried testing it and it pulls about 195 watts (I put a meter on it) regardless of knob position, and will not heat a 2 litre vessel of 1 litre of water above 60 deg C (took an hour to confirm this) , it is rated for 450 watts and max temp of 350 deg C Was wondering if there may be a way to fix it. My analog electronics is a bit rusty but I can manage component level replacement and soldering. Just hesitant to ta…

I am currently trying to find a cheap liquid nitrogen dewar to do some experiments with. Where would be the cheapest place to get a small dewar? I am located in Michigan if prices are region based and where to get them. Thanks, zarnold16

Hey guys, I've been working with my teammates on a website for science equipment and supplies. We strive to create a platform which is simple to use and people can just easily find what they are looking for. We are still working on the website and we have some issues to fix but we really wanted to hear back from people that could potentially be our customers. We'd be grateful to receive some feedback to help us improve in the long term to come! Here is the link: removed by moderator

Hello everyone! I'm new to this site but am hope I can pick your knowledge a bit! I have been searching for hours on I and can't find what it's called. I'm referring to a type of glass dropping bottle with a extremely thin dropper that doesn't come to a point in the bottle, and the other end of of the dropper has no rubber bulb, instead has a small glass cylinder with a hole that you put your finger over to create a vaccine and pull up whatever reagent or liquid is in the bottle. I can't even find a picture to post with this text, however, I've seen them in person a long time ago being used as a reagent dropper bottle . Anyone out there that can help, I would be so appr…

I want to make an Fourier Transform Spectrometer in the visible range. I am having problems with finding a proper linear stage. The wavelength range is 400-1100nm, which makes out the smallest resolution and accuracy should be better than 150nm. The wavelength resolution at 1100nm should be 1nm, which works out the track length to be greather than 2mm. The system f# makes that the mirror should be of 50mm size, which makes its weight to be 50g. I don't want to get into the argument that a dispersive system is better. I know that. Please help me find a component which will help me displace 50g weight at a resolution of <150nm for a total track length of >2mm. …
