Laboratory equipment quiz 2: Leibig vs. Fredrich Condenser Liebig Condenser: The Liebig condenser is one of the simplest and most commonly used types. It consists of a straight glass tube within a larger glass jacket. Coolant \(usually water\) flows through the jacket, cooling vapors that pass through the inner tube. It's typically used for simple distillation processes where vapors do not require extensive cooling. Friedrichs \(or Friedrich\) Condenser: The Friedrichs condenser has an inner coil like the Graham condenser, but also includes a series of bulges or indentations which increase the surface area even more. This design is very effective for refluxing operations where prolonged cooling is required. The large surface area allows for efficient condensation of vapors over a longer period.

How to do froth flotation test in laboratory.

For any material scientists / chemists out there, I would appreciate if someone could point me in the right direction! 4 sets of samples were flexural tested (3 point bend), all samples were epoxy / nylon laminates. 2 included carbon nanotubes and 2 were without carbon. 2 samples without CNTs were cured differently (oven cure vs ambient) and same for the 2 samples with CNTs. The 2 samples without CNTs made sense (oven cured performed better) but with the CNTs the ambient cured sample performed better. Why does the addition of CNTs cause the oven cured sample to perform worse than the ambient cured samples. Oven cured sample also has a Tg 20 degrees higher!

Blockages and sample carryover are a thing of the past, thanks to septum-free direct injection and effective rinsing technique. And because the multi N/C 2300 works without valves and tubes, wear and tear are very low. In short, a robust, durable lab mate that does the job without grumbling or growling.

Our new Eagle Vizion Flake Analyzer examines the exact composition of the flake samples and shows us a report, partly incl. photos of the detected impurities. When programmed it will sort out unwanted material. The precise analysis records 49 different substances and displays them separately. Our colleagues in the laboratory appreciate the easy handling and the automatic process. The device is an important part of our quality management. #flakeanalyzer #qualitymanagement #laboratory

[Question][Yolov8, Knowledge Distillation] Does anyone achieve yolov8’s better accuracy performance than baseline accuracy by using knowledge distillation method ? I have been studying knowledge distillation for about 3 months now and implemented the code to apply it to yolov8. (focal and global knowledge distillation for detectors, https://lnkd.in/gDjEfbtm) And my goal was to distill the performance of the yolov8 small model into the yolov8 nano model. But so far I haven't achieved any notable results. (It has only recovered to yolov8 nano baseline performance, which means that what has been done up to this point is meaningless.) I want to clarify whether this is my fault or a limitation of knowledge distillation. (I want to know if I overestimate knowledge distillation too much) I would be very grateful if many masters/doctors/seniors in this field could give me some small hints or feedback. Comment or DM!

Why do we use magnet in Soxhlet extractor??? A magnet is used in Soxhlet extraction to improve 1.solvent mixing, 2.ensure uniform heating, 3.prevent bumping during boiling. This enhances the efficiency, safety, and consistency of the extraction process. #chemistry #analytical_chemistry #organic_chemistry #Lab #lab_equipment

🔬💧 Mastering Liquid Dilution in the Lab! 💧🔬 In chemistry, accuracy is everything. Liquid dilution plays a critical role in ensuring that our samples are measured precisely and reliably. Whether you're preparing standards for a calibration curve or adjusting the concentration of a sample, dilution is where precision meets perfection! 🌡️ (Video Courtesy of Kaya Stahle Gutierrez) #AnalyticalLab #LiquidDilution #LabLife #PrecisionScience #ChemistryHacks #ResearchTips
