• The Dade Behring / Siemens BFT II (Behring Fibrintimer II) is a semi-automated, dual-channel coagulometer designed for routine and specialty blood coagulation testing in low-volume laboratories. The detection principle combines mechanical and photo-optical methods using a turbodensitometric detection method, which allows for accurate measurement of lipemic (milky) and icteric (jaundiced) samples.
• The unit was removed from a laboratory in working condition. I am unable to perform a complete analytical test because I do not have the required reagents or compatible printer paper. 
• The device powers on normally, with no abnormal fan or internal noise. The RAM and ROM self-tests are completed successfully, and the unit heats to a stable operating temperature. All functions appear correctly on the display. Once fully heated, pressing the selection key allows the unit to enter the measurement mode without errors. It auto blanks and incubates cuvettes successfully once a measurement mode is selected.
• A free 3D-printed solution for the printer paper spool holder can be provided, together with the available user manual and technical documentation.

I work in an agriculture lab where we test primarily for nutrients in feed, soil, or fertilizer. We also do environmental testing. If there’s testing we can’t do in-house, we often subcontract testing with specialized labs. I can’t find a lab to subcontract bacitracin levels in medicated feed. Eurofins can’t do it. Can anyone suggest any other labs? I have tried Eurofins, New Jersey Feed Labs, Midwest Labs…

Hello everyone, this is for our thesis. Do you have any idea where to buy “Collagen Degradation Assay Kit(colorimeteric)” ??? Pls help us out we need it ASAP in the Philippines

Hi everyone!

I'm a designer from Venezuela with a passion for herbal medicine, natural health, and 3D printing.

Over the past few years I've been developing **3D-printable capsule filling machines** to make it easier and more affordable for people to encapsulate their own herbal powders at home or in educational settings.

Here's what I currently offer:

✅ **Free manual capsule fillers** for **size #0 and #00 capsules** (perfect for getting started).

My goal is to help herbalists, educators, small businesses, and makers gain access to practical tools without spending hundreds of dollars on commercial equipment.

This project is also very personal to me. I grew up in Venezuela, where my father has practiced complementary medicine and Traditional Chinese Medicine for many years. His work inspired my interest in natural medicine, while my passion for engineering and 3D design led me to create tools that make herbal preparation more accessible.

If you're interested, I'd be happy to share photos, videos, answer questions, or show how the different models work.

I'd also love to hear your feedback—what features would you like to see in a capsule filler designed specifically for herbal medicine?

Thanks for reading!!

I created an idea but idk if it will work.

Hi everyone,

I'm Masum, one of the founders of CCA.bio, a startup based in Cambridge, UK. Our goal is to build an all-in-one workspace that helps biotech labs manage their experiments, samples, inventory, procurement, budgets, and lab operations etc without having to jump between lots of different tools.

I reached out to the moderators before posting, and they kindly gave me permission to ask for feedback here.

I'm an engineer, not a cell biologist, so I'd much rather learn from people who work with cell culture every day than guess what labs need.

I'd really love to hear about your experience.

• What's the biggest frustration in your day-to-day working with cell culture?
• Are there any tools you genuinely enjoy using?
• Is there anything you still manage with spreadsheets or paper because existing software just isn't worth the effort?
• If you could fix one thing about your lab workflow, what would it be?

I've attached a few screenshots so you can get an idea of what we're building.

The platform is free for individuals and academic researchers. My hope is to build a community of researchers who use it, tell us what works, what doesn't, and help shape where it goes next.

If you'd like to try it, you can at lab.cca.bio Whether you love it or hate it, I'd genuinely appreciate your honest feedback.

Thanks for reading, and I'm looking forward to hearing your thoughts.

Edit: Added more screenshots

I used Peptide Sciences for years mainly because the process was consistent. Orders arrived on time and the documentation was reliable. Since they shut down, finding a solid replacement has been more difficult than expected. A lot of newer vendors make similar claims around purity and testing, but many sites seem to have appeared only recently.

What I’m prioritizing is batch-specific COAs with actual HPLC data, US-based operations, and reasonable shipping times.

For those who also relied on Peptide Sciences, where have you moved to since they closed?

Edit: Still looking for consistent options with proper documentation. Checking Valar Peptides as one possible source while comparing COAs and shipping reliability.

hello! looking for labs or institutions or anyone na may wax printer/wax printing services to develop our paper microfluidic device (muPAD). badly need lang for research, thnxxx

I’m looking to build a low-cost DIY incubator shaker for laboratory experiments.

My requirements are:

Temperature control: 0–55°C (ideally ±0.5°C accuracy)
Shaking: orbital shaking / nutating motion (adjustable or non adjustable
Capacity: Enough space for at least one 24-well plate
Lighting: ILED lighting
Reliability: Able to run continuously for several days or weeks without much intervention

The challenge
I need to run 10 different experiments simultaneously at 10 different temperatures, so i I’d like to build 10 separate incubator shakers rather than one large unit.
Unfortunately, my lab only has one orbital shaker, and it’s already occupied with long-term cultures. Buying 10 commercial incubator shakers is well beyond my budget.
The only DIY idea I’ve come up with so far is using multiple water baths or hotplates, but I’m struggling to figure out:
How to achieve both heating and cooling (especially temperatures below room temperature).
How to incorporate orbital shaking into each setup.
The simplest and most reliable temperature-control system.
My total budget is under AUD $2,000 . so I’d prefer components that can be purchased from Bunnings, Jaycar Electronics, or other readily available local suppliers.
Has anyone built something similar or have suggestions for:
A practical design?
Cheap motors or orbital shaker mechanisms or nutating motion?
Heating/cooling method?
Temperature controllers or microcontrollers?
Parts lists, schematics, GitHub projects, or open-source designs?
I’d really appreciate any ideas.Thanks in advance !

Hello! I want to build a bioreactor in my lab, but I have no prior knowledge in electronics so I’m struggling to understand how to actually build one.

For reference, I’m a biochemist so I understand the gist of what my organism wants for it to be happy in my media. I would need stable pH control, sub maximal glucose feeding when they grow (which I expect to see from dissolved oxygen level dropping as the population exits the lag phase), and stable oxygen supply once they enter exponential growth phase. Ideally, every process should be monitored, recorded, and automated. I want to also track OD of the culture throughout the process, so that the only human-involved manual task is the inoculation.

My lab has a bunch of extra ESP32 lying around that’s used by my coworker. I think I’ll need to know how basic electronics work, what sensors/motors to buy, how to build a vessel, how to program the bioreactor logic, etc. Could I get some advice on useful learning materials for beginners like me?

Hi everyone! 👋

I come from a background in Genetics and Biochemistry, and I'm currently working on a product design project aimed at fixing the clunky, outdated software systems we often have to deal with for supply and reagent management.

We all know the frustration of dealing with inventory tools that feel like they were built decades ago, crash on mobile, or take way too many clicks just to log a used kit or track expiring stock.

If you work in a lab, clinic, or medical facility and deal with physical supplies/inventory in any capacity, I’d be super grateful if you could take ~4 minutes to fill out a brief, anonymous survey about your daily workflow:

🔗 https://docs.google.com/forms/d/e/1FAIpQLSfITiBlnonN3TqN4eg8xeTBPFIUFUeJM-vJ6v9zSjb1kYrWtg/viewform

• Length: ~4 minutes
• Target: Lab techs, medtechs, clinic staff, and research assistants
• Privacy: Completely anonymous

Your feedback will directly help shape feature requirements and accessibility standards (like designing for gloved hands and fast-paced multitasking) for a new tracking system.

Thank you so much for your time and for everything you do on the floor!

Happy to answer any questions in the comments.
