{"title":"Laboratory Cold Traps","description":"\u003ch2\u003eYamato Laboratory Cold Traps\u003c\/h2\u003e\n\u003cp\u003eA cold trap sits between your vacuum process and the vacuum pump, freezing out moisture and harmful vapors before they reach the pump. For oil-sealed pumps this prevents condensate from contaminating the pump oil and destroying efficiency; for dry pumps it closes the evaporation system so vapors never pass into the lab environment. Because vapors are captured as a frozen solid rather than condensing inside the vacuum tubing, evaporation rates stay high.\u003c\/p\u003e\n\n\u003ch3\u003eYamato CA-301 Cold Trap\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003ca href=\"\/products\/cold-trap-4l-max-low-temperature-at-45-c-ca-301\"\u003e\u003cstrong\u003eCA-301\u003c\/strong\u003e — Refrigerated Cold Trap, 4 L, −45 °C\u003c\/a\u003e: a worry-free, mechanically refrigerated trap that needs \u003cstrong\u003eno dry ice or liquid nitrogen\u003c\/strong\u003e.
