2-way, high speed valves used to dispense small amounts of fluids. VHS SERIES SOLENOID VALVES The Lee VHS valves are high speed, 2-way solenoid operated valves designed for applications requiring microliter and nanoliter dispense volumes. These applications include high throughput screening and drug discovery. The VHS valves feature: High speed operation: up to 1200 Hz Long life: 250 million cycles minimu…
As time has shown, much of what makes a device popular is how easily it can be incorporated into an existing set-up. In the case of micromanipulators, this process has involved designing manipulator platforms that bolt directly to the frames of the most popular microscopes. Alternatively, we also offer rock-steady, free-standing platforms that support our manipulators by clamping to the table beside the microscope. Our MT-70 s…
Lentiviruses are commonly used as viral vectors in cell and gene therapy production, delivering and steadily integrating desired genes into the genome of the host cell. However, they may also present health hazards to humans due to integration-mediated transformation and the creation of a RCL that can infect nontarget cells. While the current regulatory guidelines recommend a cell culture–based method for RCL testing, it is cu…
Adeno-associated virus (AAV) is commonly used as a viral vector in cell and gene therapy production, but there is a risk of it becoming a replication competent virus (RCV) during the production process, especially in the presence of a helper virus, which can raise safety concerns. While the guidelines recommend a cell culture–based method for RCAAV testing, it is cumbersome and takes 30–45 days from sample to results. Verichec…
Heating elements embedded in grooves radiating freely into the furnace chamber give these models particularly short heating times. Thanks to their robust lightweight refractory brick insulation, they can reach a maximum working temperature of 1300 °C. These models thus represent an interesting alternative to the familiar L(T) 3/11 models, when you need particularly short heating times or a higher application temperature. T…
These UV Sterilisation Cabinets provide a convenient area for setting up PCR reactions in a nucleic acid free environment thus limiting PCR reaction contamination. Acting effectively as a low cost alternative to a clean room, the powerful UV lights on the cabinets denature nucleic acids in 5 to 30 minutes making them unsuitable for amplification. The cabinet incorporates safety features to prevent user exposure to UV light. Th…
The kit is designed for the efficient and convenient isolation of PCR products from amplification reactions. Primers, mineral oil, salts, unincorporated nucleotides, and the thermostable DNA polymerase may inhibit subsequent enzymatic reactions (e.g., labeling, sequencing or cloning of the PCR products). In addition, nucleic acids from other modification reactions (e.g., restriction-endonuclease digests, alkaline-phosphatase t…
Proteema is the right choice for the separation of all kinds of biomolecules including proteins and gelatines. The columns are silica based and can be used with eluents up to a pH value of 7. If the application requires separations at higher pH in more ‘basic’ eluents, PSS SUPREMA a polymer based material is recommended. Generally the pore-size distribution of silica based columns is smaller than that of polymeric columns, whi…

Bubbles in perfusion systems are caused by solution temperature changes. As solutions warm, they cannot hold as much gas, so they off-gas. This forms bubbles in perfusion tubing. It is especially true in inline heaters where the temperature rises dramatically. The best cure for bubbles is to pre-warm your solutions. AutoMate Scientific introduces the BubbleStop™ Syringe Heater with integrated temperature sensor and feedback. S…
