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..
USE WITH CONFIDENCE – United Scientific bottletop dispensers are ISO 9001, ISO 13485, ISO 17025, and CE certified. Outperforms ISO 8655 standards (0.5% accuracy) in practical lab environments. A calibration certificate guaranteeing ISO level accuracy and precision is provided and is valid for one year. Our dispensers are fully autoclavable at 121° C and 15 PSI for 10-15 mins..

PACK OF 100 || 100 sheets of no. 1 chromatography filter papers.
LARGE || Each sheet measures 23" x 18" and is very thin.
FOR SEPARATION || Used in chromatography to separate a sample into its component parts - Used to test for the presence of various materials, to monitor the rate and progress of a reaction or to determine the purity of a product.
USEFUL IN FUN EXPERIMENTS || Can be used for various experiments in the laboratory and at home - Paper allows students to separate most water-soluble inks into their original blended pigments to reveal their hidden coloration.
ABSORBENT || Absorbs liquids and provides more surface area for evaporation meaning more and faster evaporation which, in turn, means more vapor which is often desired.
