Purchasing Guide

Based on real user feedback, we provide the following suggestions:

  • When selecting capillaries, it is recommended to prioritize confirming key technical parameters such as inner diameter, outer diameter, and material to ensure their suitability for specific scenarios such as laboratory analysis or industrial cooling.
  • When selecting suppliers, priority should be given to product compatibility, business qualifications, enterprise activity, industry performance, and companies with industry data support to ensure supply stability and long-term cooperation potential.
  • The pressure resistance and chemical compatibility requirements for capillaries vary greatly in different application scenarios such as medical equipment or meteorological instruments, and actual needs need to be clarified before procurement.
  • For capillary tubes used in high-precision temperature control systems, it is recommended to choose suppliers with mature cases in specific fields and verify their product batch consistency.

Knowledge Base

Q

When using R22 refrigerant in a 2-meter air curtain cabinet, the capillary length is usually between 1.5 and 3 meters, but the specific value depends on the system configuration. The core lies in precise matching through low-pressure side pressure testing: the normal range for pressure is 0.05-0.1MPa in summer and -0.01 to 0.04MPa in winter. If the pressure is abnormal, it is necessary to cut or add long thin tubes in sections for fine adjustment, and avoid blind replacement.

Q

Capillary thermometer is an instrument that uses the capillary phenomenon of capillaries to measure temperature. The principle is to reflect temperature changes by utilizing the behavior of liquids when subjected to temperature changes inside capillaries. Capillary thermometers have the advantages of high accuracy, fast response speed, and easy use, and are widely used in various industries and fields.

Q

A thermometer is a commonly used tool for measuring temperature. The core of a thermometer is a glass capillary tube, which is a very small pipeline that can measure the temperature of an object using the characteristics of a glass capillary tube. This article will provide a detailed introduction to the principle and structure of the glass capillary tube in thermometers.
