A pear shaped separatory funnel usually consists of a pear-shaped funnel body, a cap, and a lower piston. We can control the flow rate of the liquid inside the separatory funnel and is commonly used to separate immiscible liquids.
Material:High borosilicate glass,very good light transmittance and good hardness.
Classification of glass pear shaped separatory funnel:
According to the liquid it contains and the functions of various parts, we classify glass pear-shaped separatory funnel as follows, our user can choose any part of them freely.
1. Graduated/ Non-graduated glass pear shaped separatory funnel:
Clear scale and accurate reading
2. Transparent/ Amber glass pear-shaped separating funnel:
Please note that the corresponding accessory colors are also different.
3. Frosted neck/ Outer screw neck/ Inner screw neck pear-shaped separating funnel:
All the necks follow the international size standard.
For Frosted neck pear-shaped separatory funnels, we can adapt the same material stopper or PTFE stopper
For outer screw neck pear-shaped separatory funnels, we can adapt PP or PTFE material screw cap
For inner screw neck pear-shaped separatory funnels, we can adapt PTFE material inner screw cap
All the stoppers and caps are carefully designed and tested repeatedly to prevent leakage.
Glass piston/PTFE piston
The glass pistons are for acid liquid and the PTFE pistons are for both acid and alkaline liquid
