2" Footmaster Leveling Caster Ivory - 550lb cap
2" Footmaster Leveling Caster Ivory This ingenious product combines the mobility of a caster, the height adjustability of a level mount, and the stability of a foot pad. The GD Series leveling caster profile is integral to its function. A thick aluminum frame is used to achieve the combination of being both strong and compact. The swivel section contains 2 sets of ball bearings for easy maneuverability. Bearing raceway sleeves made from hardened steel prevent scouring to the aluminum frame, leading to high performance and dependable reliability. Moving is easy thanks to a 50 mm diameter wheel mated with an axle shaft made of cold forged steel. And once positioned, the caster provides side access to an ABS thermoplastic thumbwheel used to lower the foot pad. As the wheel is lifted off the ground, the foot pad takes over to make the application completely stationary. Making the fine adjustments to achieve the perfect level set, even under heavy loads, is light work for this world renowned leveling caster. When it is time to move again, simply raise the foot pad to restore the freedom of mobility.

2" Standard Closed Column Extractor 115-200g
DISCLAIMER: This unit is intended for LEGAL purposes only, to be used in accordance with local laws and ordinances. Use only in extremely well ventilated areas. DO NOT USE INDOORS Our dewaxing closed column extractor is the primary tool for extracting maximum solvent, and is designed to increase productivity. This closed system can be filled about 85% with solvent before the internal pressure will equal the pressure of the can propellant. Adding dry ice to the dewaxing column on the outside of the extractor decreases the temperature of the extractor, which filters out coagulated waxes and lipids from being extracted. This provides a more efficient and productive extraction process. With a 2” stainless steel tube, this unit can be customized to your needs, handling everything from 90-270g of material. Pressure gauge, shower head, and sight glass can all be added to increase ease of use. Key Features and Description: Closed Column Pressure Extractor (Comes with 1 yr.

20L BVV™ Double Jacketed Glass Reactor
The BVV™ Double Jacketed Glass Reactors are ideal for reaction applications involving extreme temperatures. They include an inner jacket for cooling or heating and an outer jacket for vacuum insulation. The outer jacket also alleviates moisture buildup so you can always see exactly what's happening inside the system. Jacketed Reaction vessels are used for synthetic reaction of different types of materials in a controlled temperature and vacuum environment. Reaction Vessels can be used as an all in one tool for extraction, refinement, distillation, and homogenization. Consisting of an inner vessel with either one or two jackets, a reactor uses temperature differentials created by a chiller to change it's internal environment. Reaction vessels also operate under vacuum making them ideal for any atmospheric sensitive applications. They can be made out of glass or stainless steel and range in volume from 1L to 100L+. To run a reaction vessel most efficiently, you will need a chiller capable of bringing the internal temperature of the vessel to an extreme low, a chemical resistant vacuum pump, and a cold trap to catch any vapors that might pass through the condenser during operation. BVV™ Jacketed Reaction vessels are simple, cost-effective, and durable machines that allow you to process material quickly and efficiently.

It is intended to provide a starting point for learning the process. Parameters should be adjusted to suit specific needs. Clean and assemble unit. Make sure all pieces are cleaned and sterilized using an alcohol solution. Connect chiller to condenser and set to 0C (32F). Always fill a rotovap condenser from the top down (chiller output to top of condenser, chiller input to bottom of condenser). Connect vacuum pump to cold trap and connect cold trap to vacuum port on rotovap. Turn on heat bath and set to 40C (113F). Once heat bath, chiller and cold trap have reached desired temperatures, turn on rotovap motor and set speed to approximately 100 RPM (does not have to be precise). Keep in mind, higher RPM’s will increase evaporation power but also increase heat load. Start vacuum pump and allow vacuum to pull down for a few minutes before injection. Once vacuum has been pulled to a sufficient level (does not have to be precise but should be below 100 Torr), using the injection valve, very slowly inject approximately 500 mL of solution into evaporating flask and then close the valve. Allow this small amount to begin evaporating. You may see the chiller begin to rise in temperature, this is called “priming” the rotovap. Once the temperature stops rising or all liquid is almost completely evaporated, open the injection valve again very slowly so that a small amount of liquid begins to enter the evaporating flask. Do not close injection valve this time but continue to allow solution to enter the evaporating flask. At this point you must try to match the input speed to the output speed. What this means is that you should be injecting the same amount of liquid into the rotovap that is equal to the amount of liquid dripping from the condenser into the receiving flask. You will know that the input speed and output speed are matched because the chiller will remain at a stable temperature. If the chiller begins to rise, then you are injecting too much liquid. Dial back the valve until the chiller stabilizes. Once everything is stabilized, you may walk away from the rotovap if necessary. Check every so often to make sure temperatures remain stable and evaporation continues efficiently. ***Note: All units are inspected for broken glass or parts before unit is shipped.

20LB High Purity USA N-Butane R600 - 99.5% Guaranteed - Buy 2 Get 1 Free (Add 3 To Cart)
20LB High Purity USA N-Butane R600 for Extraction - Buy 2 Get 1 Free (Add 3 To Cart) This solvent is instrument-grade and helps produce a higher quality extract through the reduction of mystery oils and contaminants. This N-Butane is colorless, odorless, and clean. Butane is commonly used for butane extractions which occurs in a closed-loop extraction system. Given that butane has a boiling point of 30.2F, it can easily be re-condensed without the use of extreme temperatures. This makes butane the solvent of choice for passive recovery. Butane tends to yield a more stable extract, as polar terpenes are left behind. Another benefit to butane for extraction is that Hydrocarbon extraction is often used in large production. Large amounts of material can be extracted at once, and because these solvents have such low boiling points, they can be distilled from the extract quickly, and without using high temperatures can degrade the product. These solvents are used for full plant extracts, and post-processing can yield various consistencies. This makes butane extraction a preferable method.

250ml Bump Trap 24/40 Male to 24/40 Female
Bump traps are used on rotary evaporators between the evaporating flask and condensing column. They help prevent contamination in the collection vessel when “bumping” occurs. When “bumping” occurs substance in the evaporating flask shoots up and ends up in the collection flask, which is unwanted when operating. This bump trap features a 250ML round flask with upper 24/40 female ground joint and bottom 24/40 male ground joint. With the use of ground joints vacuum grease must be applied to assure a tight seal. Internally, there is a tube that extends and two openings on the sides. This is what stops the bumping from occurring. If any substance makes its way through the openings, it will get trapped in the flask. Vapor is still allowed to flow freely through the openings. Recommend using this bump trap on 2L rotary evaporators and other distillation setups it has an overall length of 9".

2L BVV™ Electric Lift Rotary Evaporator
2L BVV™ Electric Lift Rotary Evaporator The 2L BVV™ Electric Lift Rotary Evaporator is the ideal tabletop rotovap for small scale evaporation and recovery of solvents. Designed with ease of use in mind, the 2L allows users to separate solvents from a given mixture with minimal user input. The heating bath and temperature controls allow for precise, repeatable results. The double helix vertical condenser gives maximum surface area for condensation of vapors. PTFE seals on the entire system are made for maximum chemical resistance to ensure vacuum depth and lifespan of the system. Our rotovaps are a fraction of the price of more costly systems with the same functionaility and evaporation efficiency. 2L Best Value Electric Lift Rotovap Parts Diagram Features: Digital PID temperature and rotation speed control All PTFE valves for improved lifespan and chemical resistance Direct injection capability for continuous feeding of solution Small tabletop footprint Electric multi-level lifting mechanism for ease of use CE Listed 90-day limited warranty (excludes glassware, consumables & moving parts) Specifications: Model 2L Best Value Electric Lift Rotary Evaporator Optimum Ambient Temperature 5~25C / 41~105.8F Glass Material GG-17 High Borosilicate Power (V/Hz) 110V 60Hz Speed Regulation Digital Step-less Regulation Rotation Speed 20-198 RPM Set Temperature 0-99C / 0-210F Temperature Control Digital Temperature Control Maximum Vacuum Pressure -29.8 inHg Evaporating Flask Capacity 2L (2000mL) Receiving Flask Capacity 1L (1000mL) Condenser Style Vertical Double Helix Evaporation Capacity Alcohol >/= 1 L/H Heater Max Current Draw (Amps) 13.6 Water Bath Material Teflon Composite Water Bath Size 10 x 5 in.

It is intended to provide a starting point for learning the process. Parameters should be adjusted to suit specific needs. Clean and assemble unit. Make sure all pieces are cleaned and sterilized using an alcohol solution. Connect chiller to condenser and set to 0C (32F). Always fill a rotovap condenser from the top down (chiller output to top of condenser, chiller input to bottom of condenser). Connect vacuum pump to cold trap and connect cold trap to vacuum port on rotovap. Turn on heat bath and set to 40C (113F). Once heat bath, chiller and cold trap have reached desired temperatures, turn on rotovap motor and set speed to approximately 100 RPM (does not have to be precise). Keep in mind, higher RPM’s will increase evaporation power but also increase heat load. Start vacuum pump and allow vacuum to pull down for a few minutes before injection. Once vacuum has been pulled to a sufficient level (does not have to be precise but should be below 100 Torr), using the injection valve, very slowly inject approximately 500 mL of solution into evaporating flask and then close the valve. Allow this small amount to begin evaporating. You may see the chiller begin to rise in temperature, this is called “priming” the rotovap. Once the temperature stops rising or all liquid is almost completely evaporated, open the injection valve again very slowly so that a small amount of liquid begins to enter the evaporating flask. Do not close injection valve this time but continue to allow solution to enter the evaporating flask. At this point you must try to match the input speed to the output speed. What this means is that you should be injecting the same amount of liquid into the rotovap that is equal to the amount of liquid dripping from the condenser into the receiving flask. You will know that the input speed and output speed are matched because the chiller will remain at a stable temperature. If the chiller begins to rise, then you are injecting too much liquid. Dial back the valve until the chiller stabilizes. Once everything is stabilized, you may walk away from the rotovap if necessary. Check every so often to make sure temperatures remain stable and evaporation continues efficiently. ***Note: All units are inspected for broken glass or parts before unit is shipped. If unit arrives damaged or glass is broken (this does not include minor imperfections or scuffs in glassware), Customer MUST contact BVV™ within 3 days of delivery to file a claim and receive a replacement part. If customer DOES NOT contact BVV™ within 3 days of delivery responsibility for replacement parts falls on the customer and they must pay for replacement pieces.*** ***Glassware Safety Disclaimer: BVV™ is not responsible for failure of glassware which must be inspected before and after every use because it may eventually develop imperfections or damage through normal usage, mishandling, and stress caused by temperature variations. If an imperfection or damage is noted while inspecting the glassware DO NOT use the glassware because it can fail causing bodily harm or damage to the surrounding area.***
