United Scientific BTDR-3, Bottle Top Dispenser, Lab Equipment for Safely and Precisely Dispensing Research Chemicals, Oils, Solvents and Reagents from Lab Bottles/Containers (1-10ml)

The United Scientific BTDR-3 borosilicate glass and PTFE bottle top dispenser has a volume range of 1 to 10mL and dispenses liquid in 0.2mL increments with an accuracy of + or - 0.5%. The wetted parts are borosilicate glass and PTFE (polytetrafluoroethylene). Borosilicate glass is resistant to many chemicals, thermal expansion, shock, and heat, while PTFE offers high strength and resistance to moisture, temperature, thermal expansion, and flame. This bottle top dispenser has a thread size of 30mm for attaching to a lab bottle, and it includes adapters with 28mm, 32mm, 36mm, 40mm, and 45mm thread sizes for versatility. It comes with one borosilicate glass media bottle. This dispenser is used for liquid handling applications in scientific laboratories and classroom settings.

• 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.
