I. Definition and Common Applications of Glass Capillary Tubes: Glass capillary tubes are a type of glass tubing, typically finer than ordinary glass tubes. With diameters ranging from a few micrometers to several hundred micrometers, they are referred to as capillaries. Glass capillary tubes find frequent use in laboratory settings...

Centrifuge tubes commonly found in the market are mainly divided into two types: plastic centrifuge tubes and glass centrifuge tubes, with a few being made of steel. Now, let's explore the differences between plastic and glass centrifuge tubes. Glass Centrifuge Tubes Glass centrifuge tubes are made of glass, and the...

Microliter centrifuge tubes, also known as EP tubes, are small centrifuge tubes designed for use with microcentrifuges, enabling the separation and centrifugation of small-volume reagents. The tube has a round mouth at the top and a conical shape at the bottom. The round mouth enhances mechanical strength, while the conical...

A complete pipetting cycle involves steps such as pipette tip installation, volume setting, liquid aspiration and dispensing, and tip removal. Each step requires adherence to specific operating procedures. Tip Installation For a single-channel pipette, insert the pipette vertically into the tip, lightly press, and rotate slightly left and right to...

Before use, calibration is necessary, typically every three months. For infrequent use, calibration may be done every six months. Calibration can be achieved through weight calibration, where 1 mL of distilled water at 20°C equals 0.9982 g (using a milligram electronic analytical balance). Select a pipettor with an appropriate volume...
