DURAN®, borosilicate glass 3.3, clear.
- Very good chemical resistance, high thermal shock resistance (160 K)
- Scale accurate to ±5 %, with additional inverted graduations to read removed volumes
- The complete system consisting of the bottle, closure and pouring ring satisfies USP/FDA standards
The Premium laboratory bottle is the next step in the development of the standard laboratory bottle. The scale on the bottle is accurate to ±5% and the additional inverted graduations enable both the current fill level and removed volumes to be read. The bottle provides improved safety and reliability for the user with a batch certificate. Finally, the bottle's screw closure is highly temperature resistant and includes a fitted pouring ring (made from TpCh260). This closure can be used in temperatures from -196 to +200 °C and also has a PTFE coated silicone gasket. It provides exceptional sealing for liquid and gas-phase media. The closure and pouring ring contain no colouring, so ovens, drying chambers and sterilisation cabinets cannot be contaminated by dissolved colourants. Each bottle bears a retrace code. This batch identifier provides a handy reference for information such as manufacturing time, glass quality, and standards compliance. Unlike standard bottles, a corresponding certificate is included with the products supplied.
With printed retrace code (batch identification).
