A handy and time saving microcentrifuge.
Separate molecules and contamination for RNA extraction
I use this microcentrifuge for the separation of RNA molecules from our samples at a regular interval. This is very easy to maintain and use. Also, you can keep a number of tubes in one run for the fast workspace and easily change the temperature and speed by clicking the buttons. No need to be specific for any requirements which is very good to follow your protocols with ease. Happy to have and work with this machine.

Overall good tubes, easy to work with them, good results.
ELISA assays
These tubes are good to use, just a little hard to open with just one hand but they're good for the mini centrifuge and we get good results overall. For after sales care, I was told it's a very good customer service. They are a bit expensive, but good quality.

Great product to use and a good experience to use.
Preparing for PCR and another solution preparation and dilution
I have used many product for microcentrifuging, but Eppendorf have the best quality. I recommend the clearness of the wall and very minimal residues.

Ergonomic.
Basic Science Research
Easy to open/close, unlike other tubes of this size. Curved bottom is ideal for centrifuging proteins/precipitates and separating the supernatant. Best tubes I've used so far.

Great tube size!
PCR, qPCR, DNA prep
Easy to use. Unique size (5mL) has very specific uses that no other tube can fulfil. Great for PCR master mixes. Fits in same slots as 15mL conical tubes.

Performance Comparison of Eppendorf Conical Tubes: Cap Tightness, Centrifugation Stability and Leachable Levels
This application note investigates the performance of Eppendorf Conical Tubes 15 mL and 50 mL under critical conditions and compare them to other common brands used in laboratory. Conical tubes with screw cap belong to most commonly used laboratory vessel formats and are universally used in a variety of laboratory procedures. Typical applications include handling and transport of various samples and reagents, centrifugation and mixing, and many others. Being a versatile laboratory consumable conical tubes therefore have to withstand a great variety of conditions often regarded as extreme: temperatures between - 86 °C and 100 °C, high centrifugal forces (in the range of 20,000 x g), aggressive chemicals or solvents and many others. Under such broad range of conditions the tube has to remain stable and the screw cap tightly sealed ensuring protection of samples, user and equipment.
