What is a Robinson centrifuge?
Used for determining sediment and water (S&W) content of crude oil, the Robinson Air-Driven Electrically Heated Centrifuge is designed to safely operate in hazardous areas that are deemed Class 1, Division 2, and Group D.
What tube is used for centrifuge?
There are a variety of different tubes that can be spun in a centrifuge. Tubes with screw caps, or rubber stoppers, ones made of plastic or ones made of glass, the list goes on and on! However, the plastic Vacutainer is probably the most common tube used in a centrifuge, particularly in a hospital environment.
Why are centrifuge tubes used?
Centrifuge tubes are used to contain liquids during centrifugation, which separates the sample into its components by rapidly rotating it around a fixed axis. Most centrifuge tubes have conical bottoms, which help collect any solid or heavier parts of the sample being centrifuged.
What is Falcon tube used for?
Falcon conical tubes are easy to use, high quality tools to protect your precious samples. You can rely on Falcon conical tubes to maintain your sample integrity during spinning, freezing, and storage. Falcon conical tubes are made from high-clarity polypropylene.
What are polystyrene tubes?
They are molded from premium grade polystyrene for clarity or of polypropylene for impact strength and stability to common acids, alkalies, and solvents. Polystyrene tubes can withstand 1500 RPM during centrifugation.
What is Falcon tube?
Falcon conical tubes are made from high-clarity polypropylene. Combining strength, chemical resistance, thermal stability, and optical clarity, Falcon tubes provide reliable performance for all of your critical research applications.
Is Falcon tube a centrifuge tube?
Corning™ Falcon 50mL Conical Centrifuge Tubes are ideal for cell centrifugation; pelleting; separation by density gradients.
Which is better polystyrene or polypropylene?
Polystyrene is one of the most recyclable of all plastics, reducing the carbon footprint of research. Polystyrene offers better observability of results than polypropylene, thanks to its superior clarity.
What is the difference between polystyrene and polyethylene?
The Key Differences Polyethylene is remarkably dense and available in sheets, film, and fibrous forms. On the other hand, polystyrene is available in sheet, film, and foam forms. However, polystyrene can be very easily shaped and formed, especially when it is in a foam form.
What is Griffin beaker?
Standard or “low-form” (A) beakers typically have a height about 1.4 times the diameter. The common low form with a spout was devised by John Joseph Griffin and is therefore sometimes called a Griffin beaker.
How does the Robinson heated centrifuge work?
Intended to operate from a vehicle’s 12-volt system, all models are electrically heated and thermostatically controlled to hold samples at required testing temperatures. Designed and built to meet ASTM D4007 specifications, the Robinson 900 Series Heated Centrifuge is the first Robinson Centrifuge that spins the 100mL 8-inch long cone tube.
What is a short cone centrifuge tube made of?
Made to API/ASTM oil testing standards, Robinson’s 100mL 6-inch short cone centrifuge tubes are constructed from clear annealed glass, and feature etched white graduation lines for clear and accurate readings.
What is the calibration of the Robinson thermohydrometer?
The Robinson Thermohydrometers’ precision grade design meets API oil testing specifications and is calibrated to API scale Modulus 141.5 at 60°F. The hydrometers are constructed with a solid alloy ballast and are designed to permit quick penetration to the setting point, creating no air bubbles.
Are Robinson hydrometers made in the USA?
Made in USA. The Robinson Thermohydrometers’ precision grade design meets API oil testing specifications and is calibrated to API scale Modulus 141.5 at 60°F. The hydrometers are constructed with a solid alloy ballast and are designed to permit quick penetration to the setting point, creating no air bubbles.
