An apparatus for detecting analyte in sample liquid comprises at least one main chamber 20 of predetermined volume; and, within the main chamber, a predetermined amount of dry, absorbent, sensing material comprising dry superabsorbent polymer (SAP); and, within the dry superabsorbent polymer, at least one dry reaction component for detecting and for signalling the presence of analyte. The at least one main chamber may be provided with one or more rigid walls. Preferably, the superabsorbent polymer comprises particles with a diameter of 100 to 1000nm. At least two groups of SAP particles may be provided for indicating first and second analytes.

A pipette family includes pipettes of different types and each including a pipette housing, a drive apparatus, an operating element that protrudes from the pipette housing and is displaceable relative to the pipette housing, an elongated first sensing element and a control unit coupled to the elongated first sensing element. The elongated first sensing element is configured for sensing the top end of a tip plunger inserted into the axial bore of the pipette tip and pushed onto a spigot at a mounting opening. The control unit places the pipette into a state enabling pipetting upon sensing a plunger rod of a pipette tip of a subfamily of the pipette tip family that is matched to a pipette type of the pipette and places the pipette into a state that inhibits pipetting upon sensing a plunger rod of a pipette tip of a subfamily not matched to the pipette type.

本实用新型涉及样本检测技术领域，具体涉及一种适用于超薄壁离心管的防变形缓冲支撑架，包括支撑架和减震腿；减震腿的顶端与支撑架的下表面固连。本实用新型蜂窝状加强肋在减轻整体重量的同时显著提升弯曲与扭转刚度，抑制承载下的弹性挠曲与局部失稳，从而间接减少超薄壁离心管的微小形变，为多支离心管提供稳定的整体承载与定位基体，提供有效的减振与缓冲设计，解决了刚性托盘、简易泡沫垫或普通塑料支架缺陷问题，以弹簧的弹性变形吸收与耗散振动能量，对中高频振动具有良好隔离效果，与支撑架下表面固连，将整套装置与外部承载面弹性隔离，降低转运、离心或环境振动对样品的冲击，避免了超薄壁管体发生不可逆形变、甚至破损的情况。

A blood container and a method for manufacturing the same. The blood container includes a container body and an anti-fouling layer to be hydrated. The container body has an inner wall surface, and the anti-fouling layer to be hydrated covers the inner wall surface and contains a hydration polymer. A covering rate of the hydration polymer on the inner wall surface is from 50% to 100%.

The present invention relates to a pipette tip (30) for manually, semi-automatically or automatically actuated pipetting, intended to be inserted through a septum (26) into a container (20) in order to collect and inject a liquid (20), characterized in that the pipette tip (30) has one or more axial fins (37) on the outer surface of an insertion section (33), the section (33) being referred to as the finned section, allowing air to flow in or out of the container (20) during a fluid transfer process such as pipetting.

本公开提供了用于将捕获粒子分离到孔阵列中的孔中并用疏水液体密封孔的装置和方法。在某些实施例中，本公开的方法涉及：检测来自孔阵列的信号的存在，其中，该信号的存在指示被固定化在捕获粒子上的分析物的存在。在某些实施例中，用于将捕获粒子分离到孔阵列中的孔中以及用疏水液体密封孔的装置包括位于开口处的突起，这些突起被配置成阻止疏水液体在亲水液体被去除之前到达该开口。

A microfluidic valve comprises: a substrate relief-patterned at top and bottom surfaces; to define an annular valve seat and a surface for holding an elastomeric membrane inside a generally cylindrical protuberance in the top surface so that the membrane covers the cylindrical inner wall. The relief patterning also provides a through bore defining one valved microfluidic channel and an annular trough around the annular valve seat to which at least one other valved microfluidic channel extends. When the cap is pushed into the recess, it reversibly presses the membrane against the valve seat to form a seal that prevents fluid flow in the channel.

An apparatus, method, and system for isolating an extracellular matrix are provided. More particularly, the present invention discloses an apparatus, method, and system for isolating an extracellular matrix from a biological sample for use in the diagnosis and prognosis of a subject. The apparatus may have a restriction channel for isolating the extracellular matrix and a uniform flow channel for accurate pressure measurement.

A configurable port fitting for a container, such as a bioprocess bag, has one or more O-ring grooves and two opposing locking arms (e.g., 604). The port fitting is mounted onto the container by (i) inserting one end of the port fitting into a port in the container such that O-ring(s) form seals between the O-ring grooves and the container and (ii) rotating the port fitting to engage the locking arms with two opposing retention clips (e.g., 506) of the container. Some port fittings are fixed port fittings that provide a fixed opening into the container. Other port fittings are port sizers that receive a valve connector that enables flow control between closed and open positions. Port fittings of different sizes enable different flow rates. Some port fittings (and other connectors) have a threaded tube barb that receives a threaded tube retainer that secures tubing in place over the barb.
