FAQs

Why do the 100ml and 250ml models come in a 2-piece set?

Smaller reagent bottles are frequently used for comparative studies or repetitive sampling. Providing them in a 2-piece set offers better value and ensures you have a spare available for your immediate laboratory needs.

Is the Amber bottle necessary for all chemicals?

No, the Amber version is specifically for light-sensitive reagents. The dark glass filters out UV and short-wavelength light that can cause photochemical reactions. For most standard reagents where light sensitivity is not a factor, the Clear Xin Tester bottle is preferred for better visibility of the contents.

Can these bottles be used in an autoclave for sterilization?

Yes, the high borosilicate 3.3 glass is designed to withstand high-temperature sterilization. However, we recommend loosening the GL45 cap slightly during the autoclaving process to balance the pressure and prevent potential damage to the seal.

What is the benefit of the granulated bottom on the larger 10L and 20L bottles?

Large bottles can be quite heavy when full. The granulated anti-slip bottom significantly increases friction, preventing the bottle from sliding on wet or smooth laboratory benches, which is a critical safety feature when handling bulk chemical storage.
