## Overview

The EISCO Glass Burette features a 50mL capacity with precise 0.10mL graduations, crafted from durable class 'B' borosilicate glass. Its PTFE stopcock ensures chemical resistance and smooth, drip-free operation, making it perfect for educational and professional laboratory use.

## Description

EISCO burette is for laboratory use. The burette is made of acrylic for durability, and has a polytetrafluoroethylene (PTFE) plastic plunger stopcock for resistance to chemicals, moisture, and high temperatures. Made of class 'B' borosilicate glass. PTFE plastic is a strong, low-friction material that has smooth transfer, high surface release, and nonstick properties. It has high chemical resistance, and resists moisture, high temperatures, flames, thermal expansion, and ultraviolet (UV) exposure. PTFE has low temperature toughness. The burette has 50 mL capacity with 0.10mL graduation, and is suitable for high school or college students, or ages 14 to 21. Clamp not included

Review: great other than the valve . - We purchased two of these Burette for titrating phosphate , they work ok for our purpose not really a big fan of the of the valve for the solution . The glass is well made and the scale is clear and easy to use . Depending on what you are using them for could be a great option . It was not really the best suited for our situation but that is not to say it is not a well built product.
Review: Works great. - I bought one of these for homeschool chemistry lab, and it's worked great so far. There's no dripping when the stopcock is closed, readings are easy to make (at least once the kids worked out that numbers on burettes go from the top to the bottom!), and even my rough kids haven't managed to break it yet.

### ⭐⭐⭐⭐⭐ Buena calidad-precio
*by R***. on 27 April 2021*

Llego en óptimas condiciones, muy buen producto, para un trabajo analítico de universidad o menor funciona a la perfección, pero hablando de exactitud y precisión apenas cumple, fuera de ello es un buen precio y es un buen producto.
