There are three types of pipette heads: normal, filter, and low adsorption heads.

1. Common suction head.

The suction head and box can be autoclaved at 121 ° C /15psi. Suitable for different brands and different models of pipette specifications, excellent compatibility. The clarity of the tube body is good, the scale line is clear, and it is easy to observe when using. Solvent resistance. Economical paper bag packaging, reasonable PE bag packaging, to avoid environmental pollution.

2. Filter element suction head

Some students often report that when the pipette is disassembly and maintenance, they do not have the heart to look inside, and the stainless steel piston rod is etched. How to solve it? At this time, the filter element suction head can be considered.

Filter element suction is a new upgrade of the ordinary suction head. On the basis of the general suction head, the filter element suction head is added to increase the diameter, which ensures excellent ventilation while isolating the actual effect. Available in a variety of models :10/100/200/1000 microliter. Color * Transparent.

There are three major benefits: to ensure the safety of testers: it can reduce the spread of dangerous goods, and ensure the safety of actual operators to a greater extent. Ensure sample safety: no pyrogen, no Dnase/Rnase, no PCR inhibitors, avoid cross environmental contamination. Three guarantees the safe use of the pipette: prevent liquid from rushing into the cavity, maintain accuracy and accuracy, and increase the service life of the pipette.

3. Low adsorption head

The surface of the low adsorption head is treated with a hydrophobic solution to reduce the low interfacial tension liquid leaving more residue in the head. It can minimize sample damage, prevent protein digestion and absorption, and easily remove sticky raw materials, genetic DNA or fragile cell culture matrix, which is a better guarantee for obtaining high-precision detection results.
