We typically have used and reconditioned pumps in stock from leading manufacturers like Cole-Palmer and Watson/Marlow.
The Leybold D2 D2A Trivac is a durable vacuum pump with a superior vapor handling capability. The Leybold D2 D2A dual stage rotary vane mechanical vacuum pump offers an excellent ultimate pressure of 1x10-4 Torr. These pumps are commonly used for vacuum furnace evacuation, backing turbomolecular pumps, backing diffusion pumps, rotary evaporation, refrigeration system evacuation, epoxy degassing, vacuum sterilization, backing mass spectrometers, freeze drying, vacuum centrifugal applications, vacuum distillation, space research, and other vacuum processes. These Leybold D2 D2A vacuum pumps have a pumping speed displacement of 2.2 CFM.
The MJ Research PTC-100 is a robust thermocycler that provides solutions for various temperature configuration needs. This instrument comes in versions that use of 96-well or 60-well microplates, as well as a heated lid for oil-free operation. The Hot Bonnet heated lid fitted in each unit has a thumbwheel that allows for the convenient adjustment of height and pressure. The modification feature ensures the tight sealing of reaction vessels ¬and microplates ¬ during oil-free thermal cycling.
96 Well Block
The Precise Peltier-effect heat pumps of PTC-100 thermocyclers were crafted to withstand repeated cycling. Any temperature sequence can be cycled up to 10,000 times. The NIST-traceable calibration feature of this instrument allows for the indefinite storing of material at any temperature. As a result, incubation rates are highly accurate. This calibration feature is also responsible for the refrigeration of results after unsupervised runs.
Data storage is secured and hassle-free with MJ Research PTC-100 thermocyclers. Memory stores approximately 320 programs, and the cycler comes with 14 pre-programmed protocols. Any sequence of temperatures can be cycled up to 10,000 times. Ramping rates less than maximum can also be specified. Data which were not properly stored due to power interruptions are safe for up to twelve hours with the PTC-100's power-failure protection feature.
The MJ Research PTC-225 is an innovative thermal cycling system capable of simultaneously running four individual sample blocks without compromising accuracy and performance. This reliable Tetrad system is ideally suited for labs with high throughput PCR applications. Additionally, the PTC-225 Thermal Cycler features a "hot swappable" block, as well as gradient and non-gradient controlled base options. Notable features of the PTC-225 include a high-density display, an on-board point-and-click software navigation, and real-time monitoring of cycling temperature. The Tetrad PTC-225 Thermal Cycler system includes the MJ Research PTC-225 thermal cycler base and four alpha blocks (96, 384, 30x30, 60x60 well).
Savant RVT4104 Refrigerated Vapor Trap from Thermo Scientific effectively condenses and traps a wide variety of solvent vapors that can contaminate and degrade vacuum pump oil. The RVT 4104 delivers an easy, safe and practical way to protect high vacuum, oil-sealed pumps in vacuum evaporation systems. The Savant RVT4104 ultra-low temperature refrigerated vapor trap, includes a built-in temperature gauge and vacuum pump interlock to protect the pump from accidental contamination. The RVT4104 has a 4L capacity; ultra low -104°C temperature traps high volatile solvents. 0.5" ID connecting hose is a consumable and also not included The Savant RVT system is great for labs using highly volatile solvents including hexane, chloroform, acetone, and methylene chloride.
