Made of polypropylene, this Pipette Box is designed in such a way that it can hold pipettes of different lengths. The top of the box screws on the bottom and the height can be adjusted by screwing or unscrewing the top.

Friendly, efficient and reliable electronic pipette filling instrument. Designed for ease and comfort to suit all types of liquid handling needs in every Laboratory. Available in two attractive designs to cater individual preference.

FEATURES :
• Two LEDs
– Red – low charging
– Green – Charging status.
• Continuous adjustment of pump speed during operation.
• An universal Silicon collect is provided to accept all standard pipettes up to 100ml. Internal knurlings on the collet holds the pipette firmly.
• Comfortable grip.
• In-line membrane filter (0.2 micron) prevents
a. Aerosol Contamination.
b. Liquid from entering the equipment by accident.
• Ni-MH 3.6V rechargeable batteries are used in combination with low power consumption circuit and vacuum/pressure pump. Allows eight hours of continuous operation.
