Pertanyaan yang Sering Diajukan
Pertanyaan umum tentang WHEATON dari 3G Electric.
What types of glass are used in WHEATON lab bottles?
WHEATON glass lab bottles are typically manufactured from Type I borosilicate glass or soda-lime glass, depending on the specific product line. Type I borosilicate glass offers high thermal resistance and chemical durability, making it suitable for autoclaving and use with aggressive reagents. Soda-lime glass is used for general-purpose applications where cost efficiency is prioritized. The specific glass type is indicated in the product specifications for each SKU.
Are WHEATON BOD bottles compatible with automated testing systems?
Yes, WHEATON BOD bottles, such as the 300 mL model with a robotic stopper (SKU 48H604), are designed for compatibility with automated biochemical oxygen demand testing systems. The robotic stopper allows for direct insertion into analyzers without manual capping, and the narrow mouth ensures consistent sample introduction. The bottles are manufactured to standard dimensions to fit common BOD instrument trays.
What closure options are available for WHEATON glass scintillation vials?
WHEATON glass scintillation vials, like the 20 mL sample vial (SKU 48H848), typically include a polypropylene screw closure with a 24-400 mm thread size. The closure is included with the vial and is designed to provide a leak-resistant seal. For other vial sizes, closures may be available separately, including aluminum seals or snap-on caps, depending on the specific product configuration.
Can WHEATON cold storage boxes be used in liquid nitrogen?
WHEATON cryogenic vial freezer boxes, such as the fiberboard model (SKU 6EMW3), are designed for use in cryogenic environments, including liquid nitrogen vapor phase. The fiberboard material provides insulation and structural integrity at temperatures down to -196°C. However, they are not intended for direct immersion in liquid nitrogen; they are suitable for storage in vapor-phase freezers or mechanical freezers.
What is the accuracy of WHEATON bottle top dispensers?
WHEATON bottle top dispensers, such as the 50 mL capacity model (SKU 23NC18), have a specified accuracy of +/-1.1% across the dispensing range of 5 mL to 50 mL. This accuracy is achieved through precision-machined components and a calibrated adjustment mechanism. The dispensers are designed for reproducible liquid handling in laboratory settings.
Are WHEATON glass bottles graduated?
Many WHEATON glass lab bottles, including the rectangular glass lab bottles (SKUs 48H782 and 48H802), are not graduated. They are supplied without volume markings, as they are intended for storage or transport rather than precise measurement. For graduated options, WHEATON offers other product lines such as graduated cylinders or volumetric flasks, which are available separately.
