The gas jet is formed by directing boiling silicone vapors through a hollow cone. There are no internal moving parts. The pumping action commences when the vacuum pressure in the still (i.e. wiped film) goes below 0.2 torr (200 millitorr). On an empty, leak free still, ProBoost backed by a rotary vane pump lowers the vacuum pressure to 0.00002 torr (20x lower in pressure than a 2-stage rotary vane vacuum pump can do alone). \u003c\/p\u003e\n\u003cp\u003eProBoost backed by a rotary vane vacuum pump will lower vacuum pressure to below 0.0001 torr in high vacuum and Schlenk lines. This high vacuum is invaluable to improve the results from reactions using air-sensitive compounds such as organometallics, metal amides, and hydrides. \u003c\/p\u003e\n\u003cp\u003eProBoost has a built-in control board for fan and heater. When you turn on ProBoost, the fan and heater both turn on. When you turn off ProBoost, the heater turns off immediately and the fan runs for another 20 minutes to cool the pump. \u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cstyle type=\"text\/css\"\u003e\u003c!--\n.tg  {border-collapse:collapse;border-spacing:0;}\n.tg td{font-family:Arial, sans-serif;font-size:14px;padding:7px 5px;border-style:solid;border-width:1px;overflow:hidden;word-break:normal;border-color:black;}\n.tg th{font-family:Arial, sans-serif;font-size:14px;font-weight:normal;padding:7px 5px;border-style:solid;border-width:1px;overflow:hidden;word-break:normal;border-color:black;}\n.tg .tg-1wig{font-weight:bold;text-align:left;vertical-align:top}\n.tg .tg-bn4o{font-weight:bold;font-size:18px;text-align:center;vertical-align:top}\n.tg .tg-0lax{text-align:left;vertical-align:top}\n--\u003e\u003c\/style\u003e\n\u003ctable class=\"tg\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth class=\"tg-bn4o\" colspan=\"2\"\u003eSpecifications\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd class=\"tg-1wig\"\u003eMaximum Pumping Speed, Air\u003c\/td\u003e\n\u003ctd class=\"tg-0lax\"\u003e80 l\/sec\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd class=\"tg-1wig\"\u003eUltimate Vacuum Pressure\u003c\/td\u003e\n\u003ctd class=\"tg-0lax\"\u003e0.00002 torr\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd class=\"tg-1wig\"\u003eMinimum Back Pump FAD at 60 Hz\u003c\/td\u003e\n\u003ctd class=\"tg-0lax\"\u003e2.8 CFM\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd class=\"tg-1wig\"\u003eMaximum Discharge Pressure\u003c\/td\u003e\n\u003ctd class=\"tg-0lax\"\u003e0.2 torr\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd class=\"tg-1wig\"\u003eAmbient Environmental Temp\u003c\/td\u003e\n\u003ctd class=\"tg-0lax\"\u003e10–30°C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd class=\"tg-1wig\"\u003eHeat-up time\u003c\/td\u003e\n\u003ctd class=\"tg-0lax\"\u003e7 minutes\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd class=\"tg-1wig\"\u003eInlet Connection\u003c\/td\u003e\n\u003ctd class=\"tg-0lax\"\u003eNW50\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd class=\"tg-1wig\"\u003eDischarge Connection\u003c\/td\u003e\n\u003ctd class=\"tg-0lax\"\u003eNW25\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd class=\"tg-1wig\"\u003eSilicone Oil Capacity\u003c\/td\u003e\n\u003ctd class=\"tg-0lax\"\u003eApproximately 30 ml\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd class=\"tg-1wig\"\u003eCool Down Time\u003c\/td\u003e\n\u003ctd class=\"tg-0lax\"\u003e20 minutes\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd class=\"tg-1wig\"\u003ePump Dimensions, L x W x H\u003c\/td\u003e\n\u003ctd class=\"tg-0lax\"\u003e5.5 x 5.4 x 7.5 in\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd class=\"tg-1wig\"\u003eWeight\u003c\/td\u003e\n\u003ctd class=\"tg-0lax\"\u003e5.6 lbs (2.5 kg)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0231\/7685\/files\/Manual_CRVpro_2.pdf?12\"\u003eDownload Manual\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e \u003c\/p\u003e","brand":"BVV","offers":[{"title":"115V 60Hz 1Ph with N Amer 115V Plug","offer_id":43818343727140,"sku":"1392B-01","price":3950.0,"currency_code":"USD","in_stock":true},{"title":"230V 50\/60Hz 1Ph N. american 230V Plug UK Plug and Shuko plugs","offer_id":43818343759908,"sku":"1392C-02","price":3950.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0254\/3914\/1924\/files\/welch_proboost_solo_1024x1024_8f690108-84e7-4bc2-b629-d82f4fdb0b2a.jpg?v=1773856982","url":"https:\/\/www.growitdepot.com\/products\/welch-proboost-air-cooled-diffusion-pump","provider":"Grow It Depot","version":"1.0","type":"link"}
