Globe Scientific 111568 Polypropylene Graduated Microcentrifuge Tube with Snap Cap, Round Bottom, Natural, 2mL Capacity, Pack of 1000

Producto de calidad y resistente.

I use these for oil samples and ship them all over the world. They stay sealed nice and tight.

I use these to ship baby tarantulas, so I can't speak for their use in a centrifuge. However, the hinged lids lock well and open easily.

Great for storing serum samples....

Using these for Girl Scout swaps. We filled with glitter so I used a little hot glue to secure the lid in a way that wouldn't make the church janitorial staff hate me.

Great Value. Product as Described

I didnt realize just hoe many of these I was ordering. Was WAY more than I expected. But not like it costs a lot. These things are super handy

All products are totally heavily dirty - dust inside! How can it be used for science if it is completely dirty!? Customers pay attention to this comment, this is important! How can I spend the time and alcohol, to clean this product from waste? The manufacturer is obliged to check the goods before shipment. I demand compensation! For my work is impossible using dirty materials!!! AWFULLY!

Bought these as well as some 1.5ml tubes with pointed ends for easier measurements of small quantities. These are small tubes, low mass, high RPM If you have ever used a centrifuge in a lab, you have probably used these.. if not, you can relax knowing they are not going to leak or the lids pop off. Big bag, could take me years to get through them since I am only using them to test for sediments in cooling fluids.

Exactly what I was looking for

As described nice fut lids

Good for price

Cumplió con mis expectativas.
