Tygon R-3603 真空管|Saint-Gobain|圣戈班|真空管，具有質密超厚管壁，真空度可達到 759mm Hg/23℃至 686mm HG /60℃；可耐真空泵油及大部分無機化合物，不易老化。其蒸汽壓低，允許*小真空度為3×10-2mm HG/74℃，使用于氣體，蒸汽的分析測試。

?Tygon® R-3603 Vacuum Tubing has extra-heavy walls that will withstand a full vacuum at room temperature (29.9" [759 mm] of mercury at 73 deg. F [23 deg. C]) and up to 27" [686 mm] of mercury at 140 deg. F [60 deg. C].
?Like standard Tygon® R-3603 Laboratory Tubing, Tygon® R-3603 Vacuum Tubing resists most inorganic chemicals and can be used in corrosive atmospheres.
?Clarity allows monitoring for possible backups which could result in equipment damage.
?Tygon® R-3603 Vacuum Tubing will not swell closed if vacuum pump oil should back up into it.
?Low vapor pressure (low outgassing) makes it suitable for vacuum applications down to 3 x 10-2 mm Hg at 165 deg. F (74 deg. C).
?Ideal for analytical testing of gases or vapors.
?Well-suited for use in making manometers.
