Description
Technical field
This utility model relates to chemistry instrument field, is specifically related to one brood lac dropper.
Background technology
Dropper is mainly used in the chemical reagent that transfer is a small amount of, is one of common instrument in experiment, is generally made up of rubber glue head and tip glass tube. when using dropper, rubber glue head is clutched with finger, drive the air in dropper out of, then dropper is stretched in reagent bottle, relieving hands refers to, namely reagent be inhaled into, extruding rubber glue head again, owing to experiment needing the liquid of transfer be generally chemical reagent, or even there is extremely strong corrosive chemical reagent, if imprudence inhalation dose is too much when shifting chemical reagent, reagent is easily made to enter in rubber glue head, or residual chemical agents also easily flows backward in rubber glue head when keeping flat, cause the corrosion of glue head, harden, the blackening that becomes sticky even is rotted to reveal impact and is used, now just need replacing rubber glue head frequently, also easily produce to pollute to environment while causing the wasting of resources. and, dropper used in the market all only has the function of dropping transfering reagent, to be quantitatively adding roughly reagent, then cannot realize, and now needs to change instrument, brings inconvenience to experimental implementation.
Summary of the invention
This utility model is for the deficiencies in the prior art part, it is provided that one brood lac dropper.
This utility model solves the scheme of prior art problem: one brood lac dropper, including dropper, described dropper upper end is provided with glue head, and dropper is carved with graduation mark, and described dropper lower end is provided with plastic sheath.
Preferably, described glue head is connected by bonding method and dropper.
Preferably, described dropper upper end bore is more than lower end bore.
Preferably, described dropper upper end bore is 6mm.
Preferably, described dropper lower end bore is 3mm.
Preferably, described plastic sheath bore is more than 3mm.
After have employed technique scheme, the beneficial effects of the utility model are: glue head is connected by bonding method and dropper, and liquid is not easy seepage, safety and sanitation. Plastic sheath bore is more than dropper lower end bore, it is possible to well damage do not kept by protection dropper.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
In figure: 1, glue head; 2, dropper; 3, graduation mark; 4, plastic sheath.
Detailed description of the invention
