Equipment

United brand bottle top dispensers offer high accuracy at economical prices. Each dispenser is individually calibrated and certified in an ISO 17025 accredited laboratory in accordance with ISO 8655 standards. Five adapters are included with each unit for use with a wide range of bottle sizes. All wetted parts are made from PTFE and borosilicate glass for maximum chemical resistance. These easy-to-use instruments are suitable for all laboratory applications except HF. Special precautions must be taken for use, cleaning, and storage when working with concentrated fuming acids. A factory calibration certificate is provided with each bottle top dispenser. Dispensers are easy to disassemble and can be recalibrated in the lab. Fully autoclavable at 121°C, 15 psi for 10 to 15 minutes. (1 per EA)

Our Variable Volume Micropipettes feature built-in tip ejectors and autoclavable tip cones. They work on a click stop digital system, are easy to calibrate and maintain, and easy to disassemble for autoclaving. Manufactured in an ISO 9001:2008 certified f (1 per EA)

This series of digital heating mantles includes a built-in stirrer function. Separate knobs control the temperature level up to 400° C and stirring speed up to 800 rpm. The external probe allows the temperature of the contents of the flask to be directly measured. Case is constructed of durable stainless steel and aluminum materials. Knitted mantle is made from glass fiber yarn and designed to securely hold round bottom flasks with the top half of the flask visible during operation. Available in various sizes to hold flasks from 100 ml to 5000 ml capacity. Includes a spill collect system to drain solution if a flask breaks during use. (1 per EA )

These autoclavable desiccators are made of polypropylene (PP) and polycarbonate. Autoclavable at 120°C for 15 minutes. The top dome, molded in rigid and transparent PC, gives a crystal-clear view of the sample. The knurled knob on the top provides easy handling of the dome. The lower part is made of PP. An internal groove on the flange holds the silicon rubber O-ring. Vacuum grease should be applied on the flanges to make it air-tight. (1 per EA)

These autoclavable desiccators are made of polypropylene (PP) and polycarbonate (PC) and can hold a vacuum up to 740mm Hg for 24 hours without any greasing. Autoclavable at 121°C for 15 minutes. The top dome, molded in rigid and transparent PC, gives a crystal-clear view of the sample. The knurled knob on the top provides easy handling of the dome. The lower part is made of PP and includes a perforated PP desiccator plate. An internal groove on the flange holds the silicon rubber O-ring. The PP stopcock accepts 1/4" I.D. tubing and has a self-lubricating PTFE plug. Use the three-way plug to create a vacuum, release a vacuum, or for shut-off. (1 per EA)
