Instrument Model: APEX-LJ788 drug melting point apparatus Description:
APEX-LJ788 drug melting point apparatus using pharmacopoeia prescribed capillary as sample tube and liquid transfer temperature way, USES the microcomputer control temperature programmed, reliable work, high precision temperature control, measurement accuracy, good reproducibility, simple operation, in line with the pharmacopoeia of the People's Republic of China on melting point determination method in instrument equipment and methods for determining the regulations and requirements, also accord with the us, the UK, Japan and other countries for melting point determination of pharmacopoeia requirements, used in medicine, chemical reagent, spices, dye and other industry production and scientific research, the measuring organic crystal material melting point.
Applications: Melting point apparatus according to an important position in the chemical industry, medicine and research, it is an essential instrument for the production of drugs, perfumes, dyes and other organic crystal substances.
Main specification:
| Melting point range | room temperature -270 °C |
| Heating rate | 0.5 °C / min, 1.0 ° C / min, 1.5 °C / min, 3.0 °C / min, fourth gear (For other rate can book) |
| Rate deviation | <5% |
| Measurement accuracy | <200 ° C is not greater than ± 0.5 ° C> 200 ° C is not greater than ± 1.0 °C |
| Temperature presets | room temperature -260 °C within any preset |
| The temperature medium | methyl silicone oil |
| The stable liquid cup: | 250ml beaker |
| Ambient temperature | 20 °C ± 10 °C |

Performance characteristics 1, real-time temperature record the value of the two melting and early melting point, the melting point of the final record key. 2, according to the provisions of the Pharmacopoeia melting point determination, the samples should be in the liquid temperature below its melting point of about 10 °C placed pass temperature liquid, and then the rate constant temperature until the sample melted, with the temperature preset function Pharmacopoeia requirements. 3, have been recorded under the preset value, the next time you turn on the preset temperature is the preset value. 4, after the preset temperature is reached, the time delay of about 1 minute, so that the liquid in a stable temperature state, the buzzer. 5, when the sample is melted early melting, and finally melting key to record the beginning of the melting point, the end of the melting point of the value. 6, there are three operating states: the reset state, the state of readiness test status. 7, the beginning of the melting point of the key, and finally melting point key can also be used to measure the melting point of the two samples, the melting point of a sample of the early melting point record value Final melting point of the record another sample melting point value.
