the sample bottle. 4. If Pyrex bottle with glass stopper is used, insert the greased stopper into neck of the bottle and twist to form a good airtight seal between the stopper and bottle. Seal the sample bottle with rubber band and collar (if band is lost, use el ectrical tape over the stopper and under the bottle).
PET scintillation vials show optimum performance in the laboratory. PET provides an unbreakable plastic vial with the clarity of glass and a low background count. Polypropylene scintillation vials are a general purpose vial that can be used for liquid scintillation counting, gamma counting, chromatography, sample storage and culturing.

standard Schlenk techniques. Synthesis was adapted from Schaak et al.1 1-octadecene (50 mL, 156.6 mmol), oleylamine (30 mL, 91 mmol), nonanoic acid (10 mL, 56.5 mmol) were added to a 500 mL 3-neck flask equipped with a thermowell, condenser, and septum and was degassed at 120 ºC for 1 hour. In the glovebox, Co 2(CO)
Ten grams (in a vial) or 20 g (in a flask) of peach pulp (fresh, frozen in liquid nitrogen, and frozen in a freezer at –16 °C) were spiked with internal standard 1-octanol (0.23 mg/kg final concentration in pulp) and placed into a vial or in an artisan-made glassware single-neck round-bottom flask.
Chemistry is a subject that scares a lot of people. But not Edith Hernandez. While her friends asked for dolls, clothes, and makeup from Santa Claus, Edith Hernandez, Former Corning Plant Manager in Monterrey, Mexico, requested a PYREX chemistry set. Thus began her love affair with chemistry—and the glass that’s always been a central part
A single-factor gradual optimization method was developed in this experiment in order to improve the headspace solid-phase microextraction (HS-SPME) effect of volatile compounds in pepper chicken soup. The different extraction conditions included fibers with different coating materials, sample volume, extraction temperature, and extraction time. The total peak areas and the numbers of valid
Unless otherwise specified, the substrate 1 (0.50 mmol), was added under air in a 20 mL crimp neck vial equipped with an aluminous headspace cap. Afterwards the vial was transferred into the glovebox, AgBF4 (10 mol%, 9.73 mg) was added and the reactor was sealed, DCM (2 mL) and substrate 2 (0.75 mmol) were added and the reaction was exposed
