Duran laboratory bottle, clear, graduated, GL 45

Product information "Duran laboratory bottle, clear, graduated, GL 45, without screw cap and pouring ring, 100 ml"

The DURAN Original graduated laboratory bottle is a narrow-neck bottle with a GL thread according to DIN 168-1, made from clear borosilicate glass 3.3. The thread type depends on the volume: GL 25 for 10 and 25 ml, GL 32 for 50 ml, and GL 45 for 100 ml and above. We offer the bottle in sizes ranging from 10 ml to 20 l, with or without a cap, as well as the 25-litre bottle with a cap. Matching screw caps are available for all three thread sizes.

Glass and standards

The glass complies with Type I according to USP <660>, EP 3.2.1 and JP <7.01> and meets ASTM E438 Type I Class A. The bottles are manufactured according to ISO 4796-1:2016, with the exception of the 10 ml bottle and the 25 ml bottle without a cap. An application has been submitted for the 25-ml bottle without a cap to be included in the standard. Each bottle bears a Retrace Code. This allows the batch to be traced; the certificate is available for download at cert.dwk.com.

Closure and pouring ring

The version with a cap comes with a blue screw cap made of PP and a non-drip pouring ring made of PP; both are suitable for use up to 140 °C. All components are autoclavable at 121 °C or 134 °C. The version without a closure consists solely of the glass bottle.

Graduation and volume

The scale is fired on as a white print, with a labelling field for the contents next to it. The graduations serve as a guide when filling. The nominal volume is less than the brim-full volume: for the 100 ml bottle, the brim-full volume is 138 ml.

Typical applications

Long-term storage of solutions, buffers and reagents in glass
Sterilisation of media in autoclaves (version with cap, 121 °C or 134 °C)
Storage where Type I glass according to USP, EP or JP is required
Drip-free pouring via the pouring ring (version with cap)
Documented work with batch traceability via the Retrace Code
