".2mL PCR tubes"

Tryptic Soy Agar base with 5% Sheep Blood

This organism is commonly recovered from soil and water. As normal intestinal flora, it can also usually be found in sewage.

Sterile. For culture of Tetrahymena. Supplied in 20 x 150 mm tubes. Package of 12.

Ward's® 1100 Visible spectrophotometer is perfectly designed for high school and college students completing general analysis and experiments such as Beer-Lambert, Absorption Spectrum, Transmittance, Chlorophyll, protein (biuret test) and more. An included visible wavelength spectrum chart on the instrument panel allows the user to make the correlation between a wavelength number to an actual color on the visible light spectrum. The built-in secondary filters reduce stray light and increase precision. The design is "Student-Proofed" making this a durable unit for years of use. Large digital display makes reading much easier and the new USB interface allows for the collection of data via a computer. This spectrophotometer is designed for use with ¹/₂" (13 mm) round tubes or 10 mm square cuvettes. an adapter is supplied at no additional charge for 10mm square cuvettes. High quality silicon photodiode detector and 1200 lines/mm grating assures high performance. Auto zero function, one-touch blanking and built-in automatic filters for easy operation. Large digital display allows for quick and easy readings. Optional Windows(R) based software for easy data collection and application expansion to Standard Curve and Kinetics, Abs. and %T is available. Data can be easily exported to Microsoft Excel(R) for further processing and analysis. The software is designed for Windows based PCs, using Windows 2000, ME, or XP. Model 1100 measures Absorbance, Transmittance and now includes a USB port.

Versatile swivel bosshead test tube clamp holder to increase user friendly operations.

Excellent for cleaning semimicro tubes and other small apparatus. Has black nylon bristles with fan style tip mounted in twisted galvanized wire. Brush area is 1.5 cm in diameter by 7 cm in length; overall length is 15 cm. Package of 12.

Sturdy, non-flexible delivery tube is integrated into side of bottle.

Multipurpose catheter adapter provide a threaded, female BD Luer-Lok™ connection to tubing and can be used for general catheterization techniques

Designed for 15 and 50 ml tube box storage.

Single bore burettes with detachable rubber tube and pinch clip.

Measure sample temperature in hard-to-reach areas, including cuvettes, test tubes, flasks, and beakers.

Study the motion and behavior of gas molecules with this intriguing demonstration. An electric motor, running at 4 to 12 V DC, vibrates a small platform inside a transparent tube. This platform then violently vibrates the many small stainless steel balls inside the tube.

Tubes are suitable for collection, transport, and processing of capillary blood samples from infants, toddlers, children, geriatric patients, and patients in intensive care.

Used to control flow in flexible tubing.

Explore beautiful 3-D patterns created by a magnetic field mess free.

The movement of liquid currents due to differences in temperature is demonstrated by introducing dye into the water in the tube. One corner of the tube is heated and the movement of the dye clearly establishes the currents. The rectangular shaped tube measures 15×21 cm and has an opening at the top.
