液體處理目的是在將溶液或試劑完整、準確、精確地從一個地方轉移到另一個地方。液體處理系統應用於不同的實驗室環境，例如滴定、伏安法或離子層析測量，以及各種應用和任務，包括透過混合、移液、轉移或稀釋來添加樣品、輔助合成控制或製備標準品。

液體處理具有多種優勢：

  • 提高測量可靠性和精度
  • 結果再現性更好
  • 降低人為錯誤風險
  • 提高樣品處理量的自動化方案

自動化樣品製備步驟和常規實驗室工作流程 ( 例如手動移液或系列稀釋 ) 相比手動液體處理具有許多優勢。觀看我們的網路研討會，來了解更多關於液體處理自動化的資訊：

液體處理的優勢

Liquid handling aims at transferring a solution or reagent completely, accurately, and precisely from one place to another.

Liquid handling systems are used in different laboratory settings, such as for titrations, voltammetric or ion chromatographic measurements, and for sample preparation procedures. A wide range of applications and tasks, including dosing samples, supporting synthesis control or creating standards, use automated liquid handling techniques, such as pipetting, transferring, or diluting.

Liquid handling offers various benefits:

  • Improved reliability and precision of measurements
  • Small amounts can be dosed repeatably and accurately due to the high resolution
  • Better reproducibility of results
  • Traceable documentation of each dosing step
  • Reduced risk of human error
  • Automation options for increasing throughput

Automating sample preparation steps and routine laboratory workflows, such as manual pipetting or serial dilution, offers many advantages over manual liquid handling:

  • Save time as everything is ready to use, e.g., mix eluents with the touch of a button
  • Get better results thanks to small dosing steps and repeatability
  • Avoid human errors
  • Increase safety in the lab due to less manual handling of harmful chemicals

Changing to automated liquid handling makes sense when you want to achieve one of the following goals:

  • Better accuracy, precision, and repeatability for the solutions handled
  • Higher throughput for additions, aliquoting, standard/eluent production
  • Reduction of human errors in liquid handling tasks
  • Increased lab safety due to less contact with chemicals and less broken glass
  • Traceable and compliant documentation of all dosing steps

Electronic piston burets are by far more accurate than any glassware usually used in an analytical lab. The resolution of the dosing drives in combination with the precise glass cylinders result in a piston buret that can easily fulfill the DIN EN ISO 8655 «Piston-operated volumetric apparatus» Part 3.

Depending on the chosen drive and cylinder, the smallest possible dosing step you can achieve with a Metrohm piston buret is 0.02 µL. This is 2,500 times smaller than the pharmaceutical definition of a drop (50 µL).

Due to the high accuracy and precision, Metrohm piston burets can be used in various application fields for automated liquid handling tasks:

  • Ion chromatography: Inline sample preparation techniques including dilution, dialysis and ultrafiltration, automated eluent production
  • Titration and synthesis: Titrant, solvent, or standard addition as well as sample preparation tasks
  • Voltammetry: Sample transfer and standard addition for automated CVS systems
