How to choose a laboratory glass instrument:

Front, burner: The main purpose of the burner is to heat it, so the wall thickness is required to be uniform, not too thin or too thick, so that it is good when heated.

Second, the dish tube type, the bottle type: the tube tube mainly depends on his wall thickness and smoothness; the bottle bucket mainly depends on his wall thickness is uniform, the frosted place should be fine, and the sealing property is better.

Fifth, the vacuum class: vacuum instruments require that the scrub must be in place, the sealing must be good!

Sixth, the sand core filter class: the welding of the sand core and the glass is required to be good, and water leakage is not allowed.

Seventh, thermometer, floating meter: requires measurement to be accurate! Work well!

Eighth, matching latex and rubber products: the product can't be too thin, and the pull-up is better!
