Measures DO in mg/L or % saturation, plus 7 other parameters
Automatic salinity compensation and manual barometric pressure compensation for increased accuracy
Waterproof IP57-rated housing is ideal for field use
Versatile meter can read dissolved oxygen concentration/saturation, plus up to 7 other water quality parameters for extreme convenience. Automatic salinity and manual barometric pressure compensation provides accurate DO readings in a variety of conditions. Easy one-button pH calibration can be performed with up to 3 points for better accuracy. One-point conductivity calibration with automatic standard recognition saves time. Additional features include memory for up to 400 readings, large backlit LCD, and auto power off.
DO electrode, pH/ATC electrode, conductivity electrode, three DO membrane caps, one 30-mL bottle of DO fill solution, one 50-mL bottle each of pH buffers (4, 7, 10), one 50-mL bottle of 1413 µS conductivity calibration solution, two AA batteries, and hard carrying case.

Bst 3.0 DNA 聚合酶是 Bacillus stearothermophilus DNA 聚合酶 I，改进了等温扩增性能及反转录活性的大片段同源物，并由电脑模拟设计完成。Bst 3.0 DNA 聚合酶具有对 DNA 或 RNA 模板的 5´ →3´ 聚合酶活性和强链置换活性，但没有 5´→3´ 和 3´ →5´ 核酸外切酶活性。与 Bst DNA 聚合酶相比，Bst 3.0 DNA 聚合酶不仅具有在高浓度 DNA 扩增抑制剂中扩增的强大性能，而且反转录酶的活性也显著增强。
来源于携带重组 Bst 3.0 基因的 E. coli 菌株。
1X 等温扩增缓冲液 II [20 mM Tris-HCl(pH 8.8 @ 25℃)，150 mM KCl，10 mM (NH4)2S04，2 mM MgS04，0.1% Tween-20]。65℃ 条件下反应。
High purity Xyloglucan (hepta+octa+nona saccharides) for use in research, biochemical enzyme assays andin vitrodiagnostic analysis.
The oligosaccharides present in the mixture are XXXG, XXLG and XLLG according the letter code naming convention employed by Fryet al.1where each segment is assigned a single letter based on its sidechain motif: unsubstituted D-Glcpis assigned G, α-D-Xylp-(1-6)-β-D-Glcpsegments are named X and β-D-Galp-(1-2)-α-D-Xylp-(1-6)-β-D-Glcpis assigned L.

Cole-Parmer? General Purpose pH Electrode, 10-ft Cable
Use for many applications in a variety of housings
Preamplified version allows for long cable runs
Standard models are available with a 10- or 25-ft cable with BNC connections. Preamplified models put an end to problems associated with high impedance signals—ideal for environments with high electrical noise or high humidity. Order replacement batteries for preamplified models separately. Connect these electrodes to standard pH or ORP meters to send a signal up to 1000 ft without an external power supply. Order industrial housings seperately.General-purpose single-junction electrodes are economical yet accurate. Can be used for measurements up to pH 13. Maximum pressure is 150 psi at 25°C.
Note: 100Ω RTD ATC elements are platinum and conform to DIN curve 43760. ATC connector is miniature audio plug.
Connector for the 1 kΩ RTD and the 3 kΩ Balco ATC elements is a spade lug.
Connector for 100 kΩ thermistor ATC elements is a standard 1/4″ phone plug.
Mouse CD45R (B220) MicroBeads were developed for the positive selection or depletion of mouse B cells from various lymphoid tissues like bone marrow, lymph nodes, and spleen or from non-lymphoid sources like lamina propria, peritoneal cavity, or lung.
