Drying / Fermentation / Gas Measuring / Hybridization

Coliwasa Tubes The Coliwasa tube is used to obtain a vertical column of liquid representing an accurate cross-section of the sampled material. • Two-part borosilicate glass tube has a ball in the lower end which acts as a check valve to prevent sample loss during transfer • Both parts are prescored, allowing the unit to be easily snapped apart for safe disposal • Manufactured from 33 expansion, low extractable borosilicate glass conforming to USP Type I and ASTM E438, Type I, Class A requirements

Gas Measuring Tubes KIMAX® gas measuring tube closed at the zero end for gas measurement.

Hybridization Tubes with Screw Cap For use with hybridization incubators with rotators, these tubes offer a cleaner and safer alternative to hybridizing in bags.

Bent Drying Tubes This drying tube is used with an unsealed system to protect moisture-sensitive reactions from the atmosphere.

• Multiple Northern, Southern or Western blots (up to 5 per tube) can be hybridized in a single tube, using nylon mesh sheets to separate the hybridization membranes • Probe volumes are significantly reduced with tubes; approximately 5 mL of probe per blot • GL-45 polypropylene caps • Silicone o-rings size 323 • Manufactured from 33 expansion, low extractable borosilicate glass conforming to USP Type I and ASTM E438, Type I, Class A requirements

• Modified drying tube with an expansion bulb for CaCl 2 , as shown in the textbook, Microscale Organic Chemistry, Szafran, Pike, Singh, John Wiley & Sons, Inc. • Manufactured from 33 expansion, low extractable borosilicate glass conforming to USP Type I and ASTM E438, Type I, Class A requirements
