Кювета (ячейка образца, поглощающая ячейка) на своем базовом уровне принципиально представляет собой пробирку, предназначенную для использования с оптическим анализом. Стандартные кюветы обычно квадратные или прямоугольные в поперечном сечении, чтобы избежать артефактов рефракции. В зависимости от того, какая часть спектра находится на рассмотрении, они могут быть изготовлены из кварца или оптического стекла, хотя пластиковые кюветы существуют для менее требовательных измерений.

Glass Technical Information
Borosilicate - A glass that is high in silicate and having at least 5% boron oxide.
Linear Coefficient of Expansion - Fractional change in length of glass per degree change in temperature.
Strain Point - Maximum temperature to which glass should be heated during use"
Types of Glass:
USP Type - Pharmaceutical glass containers can be classified as USP Type I, II, III or NP.
Type I - Borosilicate glass represents the least reactive glass.
Type I glass has the least pH shift. (Lowest leaching characteristics) Coefficient of Expansion = 33 or 51 for Clear and 51 for Amber
Type II - is de-alkalized soda lime glass with higher levels of sodium hydroxide and calcium oxide.
Type III - soda lime glass - cannot be autoclaved.
Type NP - general purpose soda-lime glass used where chemical durability and heat shock are not factors.
Coefficient of Expansion = 92.

The workers clean the tubing with cloth
The workers plug the tubing into machine for making vials
The vials are transferred to QC for Physical Test
The workers put the tested vials into one big package (500-800pcs/pack)
The workers get the vials from big package and put the vials into one special tray.
Put the tray with vials into the Water injection machine
The vials in tray will be transferred to next step for Ultrasonic oscillations.
The vials in tray will be transferred to Jilt water machine.
The vials in tray will be transferred to Infrared drying case.
The workers will collect the vials after vials are dry.
The vials in tray will be transferred to next step for Ultrasonic oscillations.
The workers will check all the vials inclouding the bottom neck ,bottom ,inerts.
The workers will pack 100pieces vials into one package.
The workers will send the package to sealing machine for packing.

WHAT TO CONSIDER WHEN SELECTING AN AUTOSAMPLER VIAL
Autosampler Compatibility
Not all autosamplers are alike. Some utilize robotic arms to pick up a sample vial; some use tray rotation while others move the sampling needle to the respective vial coordinates. The dimensions of autosampler vials vary. Most autosamplers are equipped with trays that use 12x32mm vial ...Not all autosamplers are alike.
