Description
Technical field
The utility model relates to a kind of compound rest, in particular to a kind of separatory funnel, round-bottomed flask and glass funnel compound rest, can rotate freely between separatory funnel, round-bottomed flask and the glass funnel, locate.
Background technology
(1) separatory funnel is to be used for special glass instrument that mixed fluid sample is extracted, purifies and separates, is one of glass apparatus the most frequently used in chemical analysis and the test experience chamber.
Separatory funnel is that a kind of piston switch by lid (plug), bucket body and bucket body end opening is formed, make with simple glass, shape mainly contains pyriform, sphere and cylindricality etc., and pear shape separatory funnel since its have extraction mix, purify, separate thoroughly and convenient etc. become usefulness at most and the most general a kind of.The main specifications of separatory funnel is generally 60mL, 125mL, 250mL, 500mL, 1000mL, 2000mL.The separatory funnel of 125mL to 500mL specification volume is that each laboratory purposes is the widest at present, quantity is maximum.
(2) round-bottomed flask is the special glass container that is used for splendid attire, collection solvent and liquid laboratory sample and can reduces pressure concentrated, is one of glass apparatus the most frequently used in chemical analysis and the test experience chamber.
Mainly being made up of circular bottle and bottleneck of round-bottomed flask, main specifications is generally 50mL, 100mL, 150mL, 200mL, 250mL, 300mL, 500mL, 1000mL, 2000mL, 3000mL.The 50mL-300mL specification is that each laboratory purposes is the widest at present, quantity is maximum.
(3) glass funnel is the vessel that every profession and trade is used for injecting liquid, in this device, glass funnel is in conjunction with filter paper and anhydrous sodium sulfate, its effect is to transmit, collect the liquid in the top separatory funnel in the round-bottomed flask below it and remove small amount of moisture simultaneously or filter solid impurity, is one of glass apparatus the most frequently used in chemical analysis and the test experience chamber.
The main specifications of glass funnel is generally 40mm, 50mm, 60mm, 75mm, 90mm, 120mm, 150mm, 180mm, 210mm, 240mm, 300mm.The 60mm-150mm specification is that each laboratory purposes is the widest at present, quantity is maximum.
In actual the use; extract, purify, separate with separatory funnel; with glass funnel transmit, water conservancy diversion; collecting with round-bottomed flask is complete, as a to link process; and the solvent of using opposed polarity in practical operation usually extracts repeatedly, purifies, separates and collects; this just requires to be collected in the different round-bottomed flasks; and constantly separatory funnel is changed between different round-bottomed flasks; when the batch process sample, not only influenced conventional efficient, phenomenons such as round-bottomed flask is toppled over, laboratory sample order confusion have also taken place easily.
China has implemented " detecting and calibration laboratory capability Approval criterion " (CNAS-CL01:2006) in 2006, this criterion is equal to ISO/IEC 17025:2005, criterion 5.3.1 bar " is used to the laboratory facility that detects and/or calibrate; include but not limited to the energy, illumination and environmental condition, should help the correct enforcement that detects and/or calibrate ".Criterion has not only stipulated to provide corresponding laboratory facility to promote the correct enforcement that detects and/or calibrate, and requires simultaneously testing result is carried out uncertainty evaluation, guarantees that it accurately and reliably.At present, according to CNAS-CL01:2006 or ISO/IEC 17025:2005, China has strengthened each test experience chamber the input of laboratory equipment, constantly various instruments are upgraded, improved and complete equipment and measure, FAO (Food and Agriculture Organization of the United Nation) (FAO)/international food code committee of joint institution of The World Health Organization (WHO) (CAC) is according to the requirement of ISO/IEC 17025 simultaneously, formulated " the assessment guide rule of uncertainty as a result ", guide rule points out that uncertainty is mainly derived from sample extraction as a result, sample treatment and analyze three phases, and sample treatment and analysis are up to 63% to the contribution of uncertainty.
When carrying out the batch sample treatment and detecting, often time requirement is tight, sample size is big, add operation " inconvenience ", will reduce conventional efficient greatly, easily cause the manual operation error, reduce experiment accuracy and precision, the reliability of reduction experimental result even the result who makes the mistake, therefore be badly in need of being equipped with corresponding " compound rest " and shorten the time that the sample treatment process is consumed greatly, improve the efficient of sample treatment greatly, improve the testing result degree of accuracy and precision, avoid causing human accidents such as sample sequence error.
