Rubber Pipette Filler Bulb 3 Valve- An ingenious device has three Valves in them. 

This is another 3-valve pipette filler model - the SE.LW3887-01 variant. It's essentially the same type of device as the SE.LW3887-02, with the key difference being the material specification.

Product Specifications:

• Model: SE.LW3887-01- Red, SE.LW3877-01- Blue, SE.LW3867-01- Black
• Material: Chemical-resistant rubber (red/blue/black)
• Valve system: 3 valves
• Design: Standard bulb-type pipette filler

The 3 Valve Functions:

1. Air release valve - Evacuates air from the bulb
2. Suction valve - Draws liquid into the pipette
3. Delivery valve - Dispenses liquid from the pipette

Key Difference from SE.LW3887-02:

• SE.LW3887-01/SE.LW3877-01/SE.LW3867-01: Chemical-resistant rubber
• SE.LW3887-02: Silicone rubber (typically offers broader chemical compatibility and temperature resistance)

Both models serve the same purpose - safe, controlled pipetting without mouth contact. The silicone version (LW3887-02) is generally preferred for more aggressive chemicals or applications requiring autoclavability, while the standard rubber version (LW3887-01) is suitable for routine laboratory work.
