Thomas Scientific products

Self-contained anaerobic systems featuring the exclusive BBL room temperature catalyst. Uses GasPak or GasPak Plus hydrogen and carbon dioxide generator envelope; does not require vacuum pumps, gas tanks, manometers or pressure-reducing valves. GasPak products are utilized for the generation of anaerobic, microaerophilic or CO2 enriched atmospheres. The generation of these atmospheres is achieved either with gas-generating tablets or with iron powder and inorganic carbonate. In either method, the reaction takes place within a container designed for this purpose. An indicator is placed in the container to indicate when anaerobiosis is complete. System includes: GasPak 100 polycarbonate jar (9 x 5 in.); GasPak 100 lid with O-ring gasket (rubber); clamp/thumbscrew assembly; catalyst reaction chamber; two catalyst charges; GasPak 100 rack for 12 x 100 mm culture dish; GasPak tube holder for thirteen 16.5 x 128 mm tubes.

The CL10 is for low-speed clinical applications. The CL10 features a broad choice of rotors and user-friendly controls. It spins six different swing-out and fixed angle rotors up to 16 x 5/7 mL vac and 6 x 50 mL conical, with minimal sample temperature increase and very low noise: only 57 dBA at full speed.

Thomas Digital Stereo Microscopes feature a built-in, high-resolution 8.5 mm ( 1/3”) CCD camera, which can produce images on TVs and monitors with approximately 80% field of view through the eyepiece. A built-in capture card converts an analog to digital signal for easy viewing on either a standard video monitor or computer. The digital stereo microscope features rugged, die-cast metal construction, a trinocular phototube inclined at 45°, diopter adjustment on both eyetubes with interpupillary distance adjustment between 54-76mm and widefield highpoint 10x, 20mm eyepiece. Strong incident and transmitted halogen illumination is provided by a top 12V, 15W bulb and a bottom 12V, 10W bulb, both with intensity control.

Compact, easy-to-use unit features sleek designing with up-to-date electronics and the latest optical components for improved capabilities and longevity. Runs tests faster, more efficiently and more accurately than the old style Spectronic 20’s. Menu driven user prompts, 10 key operation and self-diagnostic error messages simplify use. Unit includes a single position cell holder, five disposable cuvettes, RS-232C port, dust cover and operator’s manual. Model 8420S43 also features a built-in printer. Overall dimensions: 12` W x 13` D x 7` H (30 x 33 x 19 cm); weight: 10 lbs. (4.5 kg).  VISIONlite software provides users with a wide range of data handling, recording and processing capabilities for performing full spectral scans, kinetics, single and multi-wavelength and standard curves analyses.

Thomas TSXT and TSXB series electronic balances are of the highest quality for the discerning customer who demands accurate weight measurements. Each of the TSXT models includes program-controlled SCS automatic self-calibration with intelligent calibration mode with external calibration weights. At temperature changes of 2°C, the balance automatically recalibrates itself. The TSXT series offers the simplicity and accuracy you expect from a world-class balance with the versatility to meet any weighing application. These analytical models come with a precisely-designed draftshield for exceptional sample protection. TSXT models feature a 10-key keypad and animal weighing mode, adding to versatility and user convenience.

Handheld Digital Barometer measures altitude, temperature, and barometric pressure. Also has a stopwatch/time-of-day clock, compass and graphically displays the barometric pressure trend. To assure accuracy an individually serial-numbered Traceable® Certificate is provided from our ISO 17025 calibration laboratory accredited by A2LA. It indicates traceability to standards provided by NIST (National Institute of Standards and Technology).

Choose from two sizes: 10 x 40 mm or 20 x 40 mm. Cells are bi-directional for desired light path. If solution depth of 2.5 mm is desired, insert reduction plate, Thomas number 3075A30, into 10 mm glass cell. Complete with Filters (3074D10 and D35), Glass Cell (3075A40), storage case for filters and instruction manual covering colorimetric determinations of inorganic elements and organic compounds; has 3-wire cord and plug.
