Laboy Glass 1000 mL Conical Separatory Funnel, Globe-Shape Sure-Grip Body with 27# Standard Taper Joint & 4 mm PTFE Stopcock, Heavy Wall Borosilicate 3.3 Lab Glassware

This globe shaped separator funnel with a long stopper neck and straight section between the funnel body and stopcock, which provides a secure grip while shaking and also aids in clamping, with PTFE stopcock. Laboy glass flasks are heavy wall designed, made by hand-blowing to ensure uniform wall thickness, made of high-quality borosilicate glass and annealed at 800 degree Celsius, can be heated directly in an open flame and can withstand typical laboratory thermal variations in Chemistry processes like heating and cooling.

• 1000 mL GLOBE-SHAPE SEPARATORY FUNNEL – Conical/globe shaped separatory funnel with long stopper neck, ideal for medium-scale liquid–liquid extraction and phase separation in teaching and research laboratories.
• SURE-GRIP NECK & STRAIGHT SECTION – Extended neck and straight section between the funnel body and stopcock provide a secure grip while shaking and make it easy to clamp the funnel safely on a stand.
• 27# GROUND JOINT & 4 mm PTFE STOPCOCK – Top 27# standard taper joint accepts matching glass stoppers or adapters; chemically resistant 4 mm PTFE stopcock offers smooth, precise flow control and is easy to clean.
• HEAVY-WALL BOROSILICATE 3.3 – Made from thick-wall borosilicate glass 3.3 for excellent resistance to thermal shock and chemical corrosion, suitable for routine extraction with common organic and aqueous solvents.
• HAND-BLOWN & ANNEALED – Funnel is hand-blown for uniform wall thickness and annealed at high temperature to relieve internal stress, providing durable, reusable lab glassware for everyday separations.
