NALGENE
Pertanyaan yang Sering Diajukan
Pertanyaan umum tentang NALGENE dari 3G Electric.
What materials are NALGENE bottles made from, and how do they affect chemical resistance?
NALGENE bottles are manufactured from HDPE, PPCO, LDPE, and polycarbonate. HDPE offers good resistance to acids, bases, and alcohols at room temperature. PPCO provides higher temperature resistance and is autoclavable. LDPE is flexible and suitable for squeeze bottles. Polycarbonate is transparent and autoclavable but has limited chemical resistance to strong solvents. Material selection should be based on the specific chemicals and temperatures the bottle will encounter.
Are NALGENE Erlenmeyer flasks autoclavable?
Yes, NALGENE Erlenmeyer flasks made from polycarbonate, such as the 4108-0125 model, are autoclavable. Polycarbonate flasks can withstand repeated autoclaving cycles at 121°C. However, they should not be used with strong bases or organic solvents that can cause stress cracking. Always verify the specific material and temperature limits for the flask model you are using.
What closure options are available for NALGENE storage bottles?
NALGENE storage bottles come with various closure types, including polypropylene screw closures and TPE closures. Closure sizes range from 24 mm to 53B. Some bottles have attached closures to prevent loss, while others are supplied with separate closures. The closure material is chosen for compatibility with the bottle material and the intended contents. For example, PPCO bottles often use polypropylene closures for chemical resistance.
Can NALGENE wash bottles be used with organic solvents?
NALGENE wash bottles, such as the 2402-0500 model, are typically made from LDPE or HDPE. These materials have limited resistance to organic solvents like acetone, toluene, or hexane. For solvent use, select a wash bottle made from a compatible material like PPCO or fluoropolymer. Always check the chemical resistance data for the specific polymer before use.
What is the difference between NALGENE packaging bottles and storage bottles?
NALGENE packaging bottles, like the 362008-0008 model, are designed for secondary packaging or shipping of small volumes. They are often supplied without closures and may have thinner walls. Storage bottles, such as the 2104-0004 model, are intended for long-term storage of reagents and samples, with thicker walls and included closures for leak-proof sealing. Both are available in HDPE and other materials.
Are NALGENE tube racks autoclavable?
Yes, NALGENE tube racks, such as the 5970-0030 model, are typically made from polypropylene or polycarbonate, both of which are autoclavable. These racks can withstand repeated autoclaving cycles without warping. They are designed to hold test tubes securely and are available in various configurations for different tube diameters.
