Glass Stopcock

0.1mL Graduations

Automatic burette with burette tip assembly and clear storage container

The burette tip is attached with a synthetic latex tube, and a glass bead inside the tube

The bead valve allows control of the flow of liquid thus adding validity to experiments

❤【LARGE RANGE】 0.1~200ml super long range, suitable for 0.1-100ml plastic tube or pipette and Pasteur tube.

❤【LONG TIME】We use a large-capacity built-in lithium battery (non-removable), which can be used intermittently for 8 hours, 2-3 hours per charge, and can be used with a charger.

❤【RAPID DRAINAGE】LAB FISH electric pipette adopts two systems, gravity drainage and dynamic drainage. Gravity draining can use the liquid's own gravity to drain the liquid; dynamic draining can use 6-level draining mode according to the requirement of draining speed, of which the 6-level draining speed is the fastest, which can quickly discharge 25ml of liquid within 5 seconds.

[Accurate liquid extraction]-Lab Micropipette Volume Range: 2-10ml; Increment: 0.1ml.Increase or decrease the volume of aspirated liquid by rotating the piston button.The digital window display allows for more accurate volume settings and easier volume recognition.

[GUARANTEED QUALITY]-Calibrated to ISO8655 standards for precision and accuracy. All pipettes are factory calibrated and adjusted to give the volumes as specified with distilled or deionized water to make sure highly accurate.Each micropipette comes with an individual test certificate.

[EASY TO USE]-Light weight and designed for ergonomics, adjustable rotation, flexible for convenient manual operation.It has a blow-out function when draining liquid, and no liquid remains.

❤【ADJUSTABLE】The lvolume can be selected from 0.5ul to 10ml. Increase or decrease the volume of aspirated liquid by rotating the pipette head. There is a liquid volume digital screen on the pipette. You can learn more about the volume of liquid sucked through the digital screen.

❤【DURABLE】 The pipette is made of mechanically durable and chemically resistant materials which repeated autoclaving of the half pipette at 121 ℃ (252℉) and provide excellent resistance to solvents, acids and bases.

❤【LARGE DIGITAL WINDOW】Digital gear allow for easier volume identification.
