Experimental tube
1. There are many kinds of experiments and tube sizes. The type with the mouth and does not have a mouth. Ordinary type and fire resistant type 2 trial size specified. A is the length to diameter rimnok or Khanak capacity as the volume.
2.Most trials had used for chemical reaction experiment between different substance that is liquid at boiling aqueous solution used a test tube holder with a small quantity of catch each other hot hands
3.The fire-resistant experiment tube is larger than normal and thick tube. Used for various chemical burns with the flame directly on the high-temperature
. This type of bulb should not be used for a chemical reaction experiment between an ordinary bulb-like substance

preservation method 1.Cleaned with a brush, clean the tubes closed 2. stores, and functionality of the prophecy ta
insert item. Set in a secure location.

Vitro
1. vitro with several types and sizes. Species with and without oral cavity. Types of plain and refractory sample size of 2 is indicated by the length to the diameter or volume capacity of a hibiscus.
2 most used for laboratory test tube chemical reaction between the substance of a solution. Boil the liquid to a small test tube holder heated hand grips.
3.-vitro resistance to fire large. And thicker than conventional lamps For various substances burn with flame directly.
temperatures Tubes should not be used for experimental reaction Chem. Cost between a conventional tubular
storage method
1 wash with brush test tube experiments.
2 Keep Saitama Checkout In a safe location

Test tube
1. Test tubes with various kinds and sizes, types of mouth and no mouth, ordinary type and the type of fire resistant size were identified 2, length and diameter rim is outside or even เป็นปริ capacity standard
2.Test tube used for experiment of reaction between different substances are used to boil the liquid solution with small quantity. The test tube. Holder hold hot hand
3.Refractory test tube is larger and thicker than ordinary tube used for igniting with different เปลวไฟโดย directly in high temperatures. This type of tube should not be used for the reaction chem. Color between substances like ordinary tube
how to preserve
1.Clean with a brush copy of test tube
2. Put the basket, set in the East River safe
