Cole-Parmer Oakton Traceable One-Shot™ Conductivity and TDS Standard, 200,000 µS; 6 x 100 mL Vials
All Oakton Traceable conductivity standards are NIST-traceable reference materials Supplied with a calibration report from an ISO 17034 and ISO 17025 accredited laboratory These standard solutions let you calibrate conductivity instruments to ensure accuracy If unopened, shelf life is one year; once opened, shelf life will vary by solution value. Standards have detailed labels: KCl, NaCl, and 442 conversions, temperature corrections, and certified values referenced to 25C. Average accuracy at 25C is 0.25 microsiemens for 1, 5, 10 microsiemen (S) solutions, or 0.25% for all other solutions. The tested uncertainty is shown on the certificate, whichever is greater.
Cayman Chemical L-745 870hydrochlorIde 100mg
A dopamine D4 receptor antagonist (Ki = 0.43 nM); selective for dopamine D4 receptors over dopamine D2 and D3 receptors (Kis = 960 and 2,300 nM, respectively); selective for dopamine D4 receptors over α2A-, α2B-, and α2C-adrenergic receptors (IC50s = 0.00043, 0.16, 0.17, and 0.23 µM, respectively) and 5-HT2C and 5-HT1A receptors (IC50s = 0.2 and 2.9 µM, respectively); inhibits dopamine-induced inhibition of forskolin-induced cAMP production in HEK293 cells expressing human dopamine D4 receptors at 100 nM; inhibits mescaline-induced head twitches in mice at 3, 10, and 30 mg/kg
