Using method of the present invention:
Pretreatment: wiping sterilizing is carried out to magnetic base suction pipe, each part of pipettor rack with thimerosal, guarantee to be arranged on the magnetic base suction pipe in super-clean bench, pipettor rack can not affect gnotobasis in super-clean bench (as frequent use, it can be placed in super-clean bench for a long time, the wiping sterilizing with thimerosal can be exempted).
The installation of magnetic bases: the position permanent magnet rotary switch 5 being threaded to pass.Now, N and the S pole of permanent magnet (8) is horizontal, and the magnetic line of force is formed closed circuit in the two blocks of soft magnetic materials 10 separated by non-magnet material 9, and magnet base adsorption plane 4 does not have magnetic, can move freely.Magnetic bases (1-7 forms jointly) are placed desired location, and concrete operations are: contacted with the vertical side plate of irony in super-clean bench by magnet base adsorption plane 4, magnet base bottom surface 7 contacts with the bottom surface in super-clean bench.By the position that permanent magnet rotary switch is threaded to out, now N and the S pole of permanent magnet is in upper-lower position, N and the S pole of permanent magnet aims at the two blocks of soft magnetic materials separated by non-magnet material respectively, from N pole to soft magnetic materials to the vertical side plate of the irony in super-clean bench to another block soft magnetic materials to S pole, the formation magnetic line of force closes, on the vertical side plate of irony that magnet base adsorption plane can be adsorbed in super-clean bench firmly.
Implement the installation of pipette support horizontal member: the height needed for selection, pipette support horizontal member altitude location lock (11-14 is formed jointly) is installed.Concrete steps are as follows: unclamp positioning lock holding screw 12, and the cylindrical hole in the middle of positioning lock is inserted in column 1, the height needed for selection, screwed in place lock holding screw, make silicagel pad 11 and the column tightly obvolvent of positioning lock.After altitude location lock installs, get pipette support horizontal member (15-19 is formed jointly), pipette support branch sleeve 19 is packed into column, the lower edge of branch sleeve is positioned at the upper limb of altitude location lock, completes installation and the altitude location of pipette support horizontal member.
Implement the installation of pipettor rack horizontal member: the height needed for selection, install pipettor rack horizontal member altitude location lock, it is identical that its installation method and pipette support horizontal member altitude location lock installation method.After altitude location lock installs, get pipettor rack horizontal member (20-23 forms jointly), pipettor rack branch sleeve 23 is packed into column, the lower edge of branch sleeve is positioned at the upper limb of altitude location lock, completes installation and the altitude location of pipettor rack horizontal member.
The order that above-mentioned 2 horizontal members are installed, can experimentally need, adopt pipette support horizontal member upper, pipettor rack horizontal member under, or pipette support horizontal member under, pipettor rack horizontal member is upper.The inner ring diameter of branch sleeve is larger than the overall diameter of column, accomplishes to allow branch sleeve rotate freely on column, can not be allowed to condition at again on column and produce significantly swing.So far, the installation in super-clean bench of magnetic base suction pipe, pipettor rack has been completed.For the sake of assurance, uviol lamp two-stage sterilization can be opened.After two-stage sterilization completes, close uviol lamp.
The placement of suction pipe: experimentally need, rotates the horizontal level of adjustment suction pipe frame plate 16.Under suction pipe, hanging groove 17 is vertically placed or is taken out suction pipe, because glass pipette root can put latex suction nozzle.Disposable plastic tube root can make the suction head portion expanded, and their diameter is greater than the diameter of suction pipe body.So the little body of diameter to insert under suction pipe in hanging groove, and the large suction head portion of diameter is stuck in the top of hanging groove under suction pipe, ensure that the vertical placement of suction pipe on pipette support, under suction pipe, there is the anti-slip baffle plate 18 higher than suction pipe frame plate at the edge of hanging groove, can prevent from being placed on the slippage of suction pipe in hanging groove under suction pipe.
The placement of pipettor: experimentally need, rotates the horizontal level of adjustment pipettor frame plate 21.Under pipettor, hanging groove 22 is vertically placed or is taken out pipettor, because pipettor root stretches in both sides, so its width is greater than the diameter of other parts of pipettor.So the little pipettor part of width can be inserted under pipettor in hanging groove, and the large pipettor root of width is stuck in the top of hanging groove under pipettor, achieves the vertical placement of pipettor on pipettor rack.
Dismounting: when needing to take out magnetic base suction pipe, pipettor rack in super-clean bench, by order from the top down, first shift out from column vertically upward and take off pipettor rack horizontal member, unclamping positioning lock holding screw, move vertically upward, take out pipettor rack altitude location lock from column.The method of taking out pipette support horizontal member is identical with the method for getting pipettor rack horizontal member, and the method for taking out pipette support altitude location lock is identical with the method that taking-up pipettor rack altitude location is locked.Finally permanent magnet rotary switch is threaded to the position of pass, takes out magnetic bases.
