INDUSTRIAL QUALITY || 50ml Burette made of high quality, heavy duty, Borosilicate 3.3 glass. Burette features a straight bore, PTFE stopcock

CLASS A ACCURACY || ±0.05ml accuracy as per DIN ISO 385

SUPERIOR DURABILITY || Autoclavable, with superior chemical durability. Low temperature gradient- can withstand high temperatures & thermal shocks. Eisco Labs proudly manufactures its own products, using only the highest grade, raw materials to ensure that they can withstand use in even the toughest laboratory environments

SAFE, PRECISE, ACCURATE – Our bottle top dispensers can be used to dispense precise amounts of chemicals, reagents, organic and inorganic solvents, oils and more from bottles or other containers. Bottletop dispensers allow you to safely dispense a fixed amount of liquid directly from a bottle to a receiving container. Bottle top dispensers help reduce the loss of reagents, save time, and reduce risk.

JAM FREE TECHNOLOGY – The ETP O-Ring ensures proper lubrication for the PTFE piston against the glass barrel to ensure a smooth and jam-free dispensing experience. Our dispensers are fully autoclavable at 121° C and 15 PSI for 10-15 mins.

CHEMICAL COMPATIBILITY – Microlit lab bottle dispensers utilize SpringlessValve technology and a PTFE piston. The absence of spring in the valve and the use of inert materials ensures high chemical compatibility with a wide range of acids, bases, solvents, organics, and inorganics (complete compatibility chart provided).
