Abstract
An extendable multiple-bottle sampling device and a method of using the device. Multiple lid holding rods nest within tubular casing segments. The casing segments have aligned bottle containers which hold unit-dose sampling bottles. These casing segments are series connected, and the device is dipped into the mixture being sampled. The last lid holding rod segment and the last tubular casing have aligned handles which are misaligned to obtain accurate volumetric sampling of pharmaceutical liquid or semi-solid mixtures, ointments, cosmetic creams and the like without wetting the outside of the sample containers.
Claims18
A multiple-sample sampling device capable of extension for taking multiple samples having accurate volumes at different depths of liquids or semi-solid mixtures, comprising:
- at least one tubular casing segment of predetermined length comprising, a slot extending from its proximate end to either its distal end or proximate its distal end, a plurality of bottle containers appended to said at least one tubular casing segment, and a handle at-its proximate end;
- each bottle container including an apertured cover, an apertured adapter positioned within said cover and a container body;
- at least one rod element means with a handle which fits inside said at least one tubular casing segment, and having multiple arms positioned perpendicularly to said at least one rod element means and ending in a right angle bend;
- each arm supporting a lid at said end;
- and
- an empty bottle secured within each bottle container by said adapter;
- whereby, said each empty bottle receives a full unit-dose sample of said liquid mixture by removing each said lid simultaneously when said lid holding rod handle is rotated, and terminating the sampling by rotating back each said lid to simultaneously cover each filled bottle.
A method of sampling a liquid pharmaceutical or cosmetic mixture by the use of a segmented sampling device, comprising:
- positioning into a liquid pharmaceutical or cosmetic mixture a first sampling device segment comprising a first tubular casing segment open at its distal end, with appended and aligned sample bottle containers containing empty sample bottles of varying sizes, and a first tubular casing segment containing a multiple lid holding rod, wherein the open sample bottles are closed by the lids;
- attaching a last segment having handles for both a last lid holder and a last tubular casing;
- turning the handle of the last lid holder rod to rotate the lids away from the open sample bottles to obtain precise sample volumes of said liquid;
- and
- returning the handle to its original position to close off the open sample bottles with the lids.
In a process of taking precise volumetric samples from a liquid containing mixture at varying depths simultaneously, the improved process comprising the steps of:
- inserting at least one tubular casing segment of predetermined length into the liquid containing mixture, wherein the casing segment comprises a slot extending from its proximate end to either its distal end or proximate its distal end, and multiple bottle containers with sampling bottles of varying unit-dose volumes contained therein are appended to said casing segment, each bottle container made up of an apertured cover, an apertured adapter positioned within said cover and a container body;
- at least one lid holding rod having multiple lids positioned on perpendicular arms being inserted in said at least one tubular casing segment;
- at least one additional sampler segment comprising another lid holding rod and another tubular casing with bottle-containing containers being added;
- a last segment made up of the tubular casing with a first handle and the lid holding rod with a second handle, the unit-dose sampler taking samples by displacing said lid holding rod handle relative to the tubular casing handle to expose and fill the sampling bottles simultaneously with the liquid contain mixture being sampled;
- and
- returning the displaced lid holding rod handle to its original position to complete the sampling.
