The pipette suction head conforms to the optimized conical geometry of ergonomics, making it compatible with the Rongtai pipette. It is universal, of good quality, and has an accurate range. The 10ml nozzle is suitable for the entire disinfection manual single channel adjustable pipette.

When purchasing a pipette, everyone is generally very cautious and wants to spend some money to buy a good brand with high accuracy; But when we buy suction heads, we don't attach great importance and will casually buy some cost-effective ones. In fact, the suction head is also the primary condition that endangers the detection results, and it is also likely to endanger the service life of the pipette.

There are three types of pipette tips: regular, filter, and low adsorption.

1. Ordinary suction head: The suction head box can be sterilized under high pressure at 121 ℃/15psi. Suitable for pipettes of different brands and models, with better compatibility. The tube has good clarity, clear scale lines, and is easy to observe during use. Solvent resistance. Affordable paper bag packaging, reasonable PE bag packaging, to avoid environmental pollution.

2. Filter cartridge suction head: Some students often report that when dismantling and repairing the liquid transfer gun, they cannot bear to look directly inside, and the stainless steel plate piston rod is corroded. How to solve this problem? At this point, the filter cartridge suction head can be considered.

The filter suction head is a brand new upgrade of the ordinary suction head. On the basis of the general suction head, a filter suction head has been added and the diameter has been increased, ensuring excellent ventilation while isolating the actual effect. There are multiple models available: 10/100/200/1000 microliters. Color * Transparent.

There are three major benefits: ① Ensuring the safety of testing personnel: it can reduce the spread of dangerous goods and ensure the safety of actual operators to a greater extent. ② Ensure sample safety: no pyrogens, no Dnase/Rnase, no PCR inhibitors, to avoid cross environmental contamination Ensure the safety of the use of the pipette: prevent liquid from entering the cavity, maintain accuracy and precision, and increase the service life of the pipette.

3. Low adsorption nozzle: The surface is treated with hydrophobic solution, which can reduce the situation where low interfacial tension liquid leaves more residue in the nozzle. It can minimize sample damage, prevent protein digestion and absorption, and conveniently remove sticky materials, genetic DNA, or fragile cell culture matrices, providing a better guarantee for obtaining high-precision detection results.
