Vacuum Pump Vapor Mist Filter
Vacuum Pump Vapor Mist Filter The BVV™ Mist Filter is our solution to capturing the oil mist exhausting out of vacuum pumps. This filter is filled with a replaceable media and will save you $ over alternative solutions like the Koby filter. The filter media is a granular food grade adsorbent and is designed to adsorb oil specifically. The granular media doesn't restrict flow on your pump, and when it becomes saturated with oil it continues to work. We recommend you change out the media when the filter is 50% soaked with oil. During certain vacuum pressures light vapor mist may momentarily exit the filter. The filters within the housing, do not have an indefinite life. Should they become dirty and clogged over the years, it can be cleaned with degreaser like CitraKlean CK-1QT then left to dry before re-loading. Media Capacity: 185 grams.

Vegetable Glycerin VG 99% Pure Food Grade USP/NF
Vegetable Glycerin BVV vegetable glycerin is plant-based for use in foods, cosmetics, and skin use. Its USP / NF which means it meets the highest quality standards and makes it suitable for any use. Our propylene glycol is primarily derived from soybeans and canola. Soybean or canola seeds are processed through a crushing, dehulling, conditioning, flaking and extraction operation into a crude vegetable oil. This vegetable oil is further processed into refined oil. The refined oil is then transformed through a transesterification process into crude biodiesel and crude glycerin. The crude glycerin is further processed through several evaporation and distillation steps into a refined, kosher USP-specification-grade Glycerin. What is glycerin? Also known as glycerol, vegetable glycerin, common sources include triglyceride-rich vegetable fats, such as soy, coconut, and palm oils. Most vegetable glycerin comes as a byproduct of industrial chemical reactions. For example, vegetable oils can either undergo a process known as saponification. or transesterification to produce vegetable glycerin. These are common steps in the soap and biodiesel manufacturing processes. They involve heating the oils under pressure or together with either an alkaline or alcohol solution. This process causes glycerin to split away from the fatty acids. Manufacturers can then extract the odorless, sweet tasting, syrup-like liquid known as glycerin.

W2 Heat Activated Natural Bleaching Clay
CHEMTEK W2 Heat Activated Natural Bleaching Clay W2 is a natural bleaching clay offering mild yet efficient results. It is heat activated to increase its adsorptive power without the use of any acids. The lack of acid prevents terpene isomerization and keeps the terpene profile the same while also slowing the oxidation rate of the oil thus increasing its shelf life. W2 is heavier in bulk density giving it lower oil retention. W2 SDS W2 Technical Data Sheet

Welch ChemStar 5.3 cfm PTFE Oil-Free Deep Vacuum Diaphragm Pump
Welch ChemStar 5.3 cfm PTFE Oil-Free Deep Vacuum Diaphragm Pump With the new ChemStar Dry, you get the advantages of two combined technologies: Roots blower and diaphragm vacuum pump. The result is an oil-free, software- driven vacuum system, ready to work on your tough chemical applications – clean, fast, and thorough. ChemStar Dry pumps quickly down (9 m³/h) to the working range for most evaporative operations (2.0 to 0.1 mbar) with an ultimate pressure of 10-2 mbar. The innovative electronically controlled vapour load optimises the pumping speed control. You can even pump corrosive vapours, since all wetted parts of the system are coated with PTFE and other proprietary coatings so they are chemical resistant. The integrated self-cleaning function also contributes to the system’s long lifetime and enables repeatable results. Take advantage of its state-of-the-art technology for optimal operating conditions and results. ChemStar Dry is suitable for all applications where high gas flow and deep vacuum are needed. Advantages: Oil-Free: no oil back-streaming, no oil maintenance/disposal, cleaner work place, cleaner samples, less maintenance Plug and Play: patented software control, auto speed control from atm to 0.07 mbar, self-cleaning function, protection from surges Low vacuum mostly without cold trap: no dry ice or trap apparatus needed, less maintenance, lower cost of ownership, extra bench space Chemical Resistant: pumps corrosive vapour/gases, TFE and proprietary coatings SKU 2070B-01 Max. pumping speed at 50 Hz in m³/h (l/min) 8.4 (140) Max pumping speed at 60 Hz in m³/h (l/min) 10.1 (168) Ultimate pressure in mbar (Torr) without gas ballast 7x10-2 Wired for 230V, 50/60Hz Intake connection DN 25 KF Exhaust connection DN 25 KF Sound level (dB) 57 Dimensions (W/D/H) in mm 460/220/470 Weight kg (lbs) 23 (50.7)

Welch ProBoost Air-Cooled Diffusion Pump
Welch ProBoost Air-Cooled Diffusion Pump Product Details Use Welch ProBoost in conjunction with a backing pump like the CRVpro to get deeper vacuum and higher flow. High Vacuum to 10⁻⁵ torr Use with high vacuum and Schlenk lines Employs air cooled diffusion pump Easy Attachment to backing pump Welch ProBoost is an air cooled gas jet pump (commonly called a diffusion pump). 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). ProBoost 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. ProBoost 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. Specifications Maximum Pumping Speed, Air 80 l/sec Ultimate Vacuum Pressure 0.00002 torr Minimum Back Pump FAD at 60 Hz 2.8 CFM Maximum Discharge Pressure 0.2 torr Ambient Environmental Temp 10–30°C Heat-up time 7 minutes Inlet Connection NW50 Discharge Connection NW25 Silicone Oil Capacity Approximately 30 ml Cool Down Time 20 minutes Pump Dimensions, L x W x H 5.5 x 5.4 x 7.5 in Weight 5.6 lbs (2.5 kg) Download Manual
