Precautions
- Check for completeness, whether there are any issues such as fastening, cracks, or damage.
- Use a suitable container to remove the sample and tightly seal the bottle cap.
- The covers cannot be interchanged to avoid sample cross contamination.
- Store the sample in a suitable environment according to its properties to avoid sample deterioration.
Product Advantage
- The bottle body is made of high-quality 3.3-material high borosilicate glass, which has low expansion coefficient and high chemical resistance, high temperature resistance, and high thermal shock resistance.
- The blue or orange cap is GL45 standard threaded mouth, the wall thickness of the bottle body is uniform.
- The bottle cap is made of PP material, which can withstand high temperature 121°C and autoclave repeated sterilization.
- All bottle caps and mouths are equipped with water pour-proof wall-hanging rings.
- Use high-quality, acid-and alkali-resistant, and corrosion-resistant inks for printing, with clear graduation lines.
- The large writing area can be written repeatedly, which is convenient for experimental observation and recording.
Frequently Asked Questions (FAQ)
What material are these square reagent bottles made of?
These reagent bottles are manufactured from high-quality 3.3 high borosilicate glass, which features a low expansion coefficient, high thermal shock resistance, and excellent chemical resistance against acids and alkalis.
Are the screw caps autoclavable?
Yes, the GL45 blue or orange screw caps are made of premium PP material. They can easily withstand high-temperature sterilization up to 121°C and are designed for repeated autoclave runs.
What sizes and capacities do these bottles come in?
The square shape reagent bottles are available in capacities ranging from 100ml up to 1000ml (specifically 100ml, 250ml, 500ml, and 1000ml specifications) in both transparent and brown glass.
Why choose the brown (amber) glass version over the transparent one?
The brown glass reagent bottles are specifically designed to store light-sensitive chemical reagents, media, or samples, protecting them from degradation caused by UV and ambient light exposure.
What are these square bottles commonly used for?
They are widely used as sampling, purification, sterile, clean, and filter bottles. They are essential for pollution detection, storing sample specimens in mining enterprises, and holding chemical solutions in laboratory settings.
How do I prevent cross-contamination when using these bottles?
To avoid sample cross-contamination, make sure that the bottle caps are not interchanged between different bottles. Additionally, ensure the writing areas are clearly marked for proper tracking.
