This saves a significant amount of time in experiments and tests.<\/span><\/p>\n<p><span style=\"background-color: transparent; color: #000000; font-family: Arial,sans-serif; font-size: 16pt;\">Accuracy of the spectrophotometer<\/span><\/p>\n<p><span style=\"background-color: transparent; color: #0e101a; font-family: Arial,sans-serif; font-size: 12pt;\">Some spectrophotometer models on the market can achieve an error rate below 1%. This is because the sample window and disc are made from quartz glass with a hydrophobic nano-coating, which helps samples form droplets through cohesion and reduces light scattering.<\/span><\/p>\n<p><span style=\"background-color: transparent; color: #0e101a; font-family: Arial,sans-serif; font-size: 12pt;\">The light source supports the observation of the sample window and checks for air bubbles during the measurement process. This helps users detect air bubbles to ensure accurate and repeatable results.&nbsp;<\/span><\/p>\n<p><span style=\"background-color: transparent; color: #000000; font-family: Arial,sans-serif; font-size: 16pt;\">Spectrophotometer calibration<\/span><\/p>\n<p><span style=\"background-color: transparent; color: #000000; font-family: Arial,sans-serif; font-size: 12pt;\">There are two types of calibration for a spectrophotometer: light source calibration and optical path length calibration. The light source&#8217;s brightness decreases over time and should be calibrated every 1-2 years. Calibration can be done based on the manufacturer&#8217;s specifications, and users can adjust the machine themselves without factory calibration.<\/span><\/p>\n<p><span style=\"background-color: transparent; color: #000000; font-family: Arial,sans-serif; font-size: 12pt;\">The biggest issue with current spectrophotometers is difficulty calibrating the optical path length. Due to varying sample concentrations, electric motors adjust the optical path length, which affects the machine&#8217;s parameters and built-in formulas. The spectrophotometer needs recalibration every 3-6 months, depending on sample usage frequency.<\/span><\/p>\n<p><span style=\"background-color: transparent; color: #000000; font-family: Arial,sans-serif; font-size: 12pt;\">Choosing a spectrophotometer with a fixed optical path length solves this calibration issue. Users can select the appropriate optical path length based on sample concentration. For low dsDNA concentrations (e.g., 2-1500 ng\/\u00b5l), a longer optical path (0.5 mm) is used, whereas for higher concentrations (1000-20000 ng\/\u00b5l), a shorter path is applied.<\/span><\/p>\n<p>&nbsp;<\/p>\n<p><span style=\"background-color: transparent; color: #000000; font-family: Arial,sans-serif; font-size: 12pt;\">In addition to these key tricks, researchers should consider factors such as choosing reputable manufacturers and suppliers of spectrophotometers who offer timely support and expertise.<\/span><\/p>\n<h2><span class=\"ez-toc-section\" id=\"Other_considerations_when_choosing_a_spectrophotometer\"><\/span><span style=\"background-color: transparent; color: #000000; font-family: Arial,sans-serif; font-size: 20pt;\">Other considerations when choosing a spectrophotometer<\/span><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><span style=\"background-color: transparent; color: #000000; font-family: Arial,sans-serif; font-size: 12pt;\">When purchasing a spectrophotometer, users should also consider specific spectrophotometer features, such as ease of operation, application expandability, and supplier support services. Most modern spectrophotometers include functions for determining concentration, quantifying nucleic acids, A280 protein, protein assays, and measuring cell optical density (OD 600).&nbsp;<\/span><\/p>\n<p><span style=\"background-color: transparent; color: #000000; font-family: Arial,sans-serif; font-size: 12pt;\">Researchers can install absorption settings, set formulas, and define tests for application expandability. Additionally, the best technical support services should be provided, such as:&nbsp;<\/span><\/p>\n<ul>\n<li><span style=\"background-color: transparent; color: #000000; font-family: Arial,sans-serif; font-size: 12pt;\">Prompt resolution of technical issues during spectrophotometer operation.&nbsp;<\/span><\/li>\n<li><span style=\"background-color: transparent; color: #000000; font-family: Arial,sans-serif; font-size: 12pt;\">Free warranty for device malfunctions not caused by the user.<\/span><\/li>\n<li><span style=\"background-color: transparent; color: #000000; font-family: Arial,sans-serif; font-size: 12pt;\">A 30-day trial, demo, and return policy if the spectrophotometer malfunctions due to a manufacturer defect.&nbsp;<\/span><\/li>\n<\/ul>\n<p><span style=\"background-color: transparent; color: #000000; font-family: Arial,sans-serif; font-size: 12pt;\">After purchasing the device, users often face additional calibration, consumables, and equipment maintenance costs.<\/span><a href=\"https:\/\/www.blue-raybio.com\/\" target=\"_blank\" rel=\"noopener noreferrer\"><span style=\"background-color: transparent; color: #000000; font-family: Arial,sans-serif; font-size: 12pt;\">&nbsp;<\/span><span style=\"background-color: transparent; color: #1155cc; font-family: Arial,sans-serif; font-size: 12pt;\">Blue-ray Biotech<\/span><\/a><span style=\"background-color: transparent; color: #000000; font-family: Arial,sans-serif; font-size: 12pt;\"> has developed the<\/span><a href=\"https:\/\/biogroupvietnam.com\/san-pham\/ezdrop-1000-micro-volume\" target=\"_blank\" rel=\"noopener noreferrer\"><span style=\"background-color: transparent; color: #000000; font-family: Arial,sans-serif; font-size: 12pt;\">&nbsp;<\/span><span style=\"background-color: transparent; color: #1155cc; font-family: Arial,sans-serif; font-size: 12pt;\">Ez Drop 1000<\/span><\/a><span style=\"background-color: transparent; color: #000000; font-family: Arial,sans-serif; font-size: 12pt;\"> microvolume spectrophotometer to reduce these issues, which meets all the selection criteria mentioned above.
