Description

Weak solution device for detecting density

Technical field

The utility model relates to experimental apparatus, more particularly, to a kind of weak solution device for detecting density.

Background technique

In the lab, often Density Detection, mesh are carried out to the external diagnosis reagent weak solution between density 1.0-1.1 It is preceding on the market detect external diagnosis reagent weak solution density method there are four types of: first is that using electronic table floatage-type densitometer into Row detection, about 3000 yuan of the price of densitometer, detection need to use external diagnosis reagent weak solution 50ml every time.Second is that using platform Formula U-shaped vibration tube method electronic densitometer is detected, the price of densitometer about 14000-18000 member, every time detection need using External diagnosis reagent weak solution 2ml.Third is that detected using handheld portable natural period of oscillation method electronic densitometer, it is close The price about 14000-21000 member of meter is spent, detection need to use external diagnosis reagent weak solution 0.5ml every time.Fourth is that utilizing range It for the glass weight immersion densitometer of 1.000-1.100kg/m3, and is measured according to Archimedes' principle, due to existing Compatible with glass weight immersion densitometer external diagnosis reagent weak solution does not contain vessel, thus be using 250ml graduated cylinder contains external diagnosis reagent weak solution, and glass weight immersion densitometer is then put in 250ml graduated cylinder and is carried out Detection；Although lower (the glass weight immersion densitometer about 22 of the price of glass weight immersion densitometer and 250ml graduated cylinder Member, about 25 yuan of 250ml graduated cylinder), but detection need to use external diagnosis reagent weak solution 250ml every time, and dosage is too big, causes to examine It is too high to survey cost；In addition, the glass weight immersion densitometer height that range is 1.000-1.100kg/m3 is 31cm, thickness Outer diameter is 1.7cm, and the internal diameter of 250ml graduated cylinder is 3.9cm, much larger than the outer diameter of glass weight immersion densitometer, therefore is put It can be tilted when in graduated cylinder, easily cause measurement inaccuracy.

Summary of the invention

The utility model aim is to provide that a kind of structure is simple, uses easy weak solution device for detecting density.

To achieve the above object, the utility model can take following technical proposals:

Weak solution device for detecting density described in the utility model, including height 31cm, internal diameter 2cm, wall thickness 0.2cm it is upper Open glass test tube, the teat glass are adapted with glass weight immersion densitometer, and lower end has the longitudinal direction of horizontal base The clamping device of the fixed teat glass is provided on strut.

The clamping device includes the positioning pipe sleeve with puller bolt that activity is set on the longitudinal holding pole, described Horizontal strut is vertically installed on the lateral wall of positioning pipe sleeve, the outer end of the horizontal strut is fixed with test tube by connecting plate and consolidates Clamp；The test tube fixing clamp is made of symmetrically arranged two curved splint, and the clamping part between two curved splints is axial It is axially consistent with the longitudinal holding pole, extend outwardly in the outer end of two curved splints and is provided with plate engaging lug, two connections The wing bolt and fastening nut that ear is worn by activity are linked together, and are covered on the wing bolt between two engaging lugs Equipped with support spring；Rubber antiskid cushion is provided on the medial surface of two curved splints.

The clamping device is two sets be arranged at intervals on the longitudinal holding pole.

Flexible protective cushion block is provided on the horizontal base corresponding with teat glass tube bottom position.

The utility model advantage is that structure is simple, uses simplicity.The glass of height 31cm, internal diameter 2cm, wall thickness 0.2cm Test tube is more adapted to existing glass weight immersion densitometer, not only greatly reduces the use of external diagnosis reagent weak solution Amount (is reduced by the dosage of each 250ml to 60ml), and compared to then thousands of or even up to ten thousand electronic densitometers is moved, glass is tried The processing cost of pipe substantially reduces；In addition, the internal diameter due to teat glass only has 2cm, when carrying out Density Detection, it is put into Glass weight immersion densitometer in teat glass will not tilt, and the clamping device of clamping teat glass, inspection are stablized in cooperation It is more accurate to survey result.
