## Abstract

Provided in part are processes for manufacturing pipette tip trays that improve quality assessment of the pipette tips therein.

## Claims

### Claim 1

A process for manufacturing a pipette tip tray, comprising:
(a) providing components comprising pipette tips and a manufacturing run for the pipette tips;
(b) assembling the components to form a pipette tip tray, wherein the pipette tips in the tray are from one manufacturing run;
(c) assigning a unique serial number to the pipette tip tray;
(d) associating the serial number to the manufacturing run of the pipette tips in the pipette tip tray; and
(e) affixing the serial number to the pipette tip tray.

### Claim 2 (depends on 1)

The process of claim 1, wherein the pipette tip tray comprises a lid component.

### Claim 3 (depends on 1)

The process of claim 1, wherein the pipette tip tray comprises a rack component.

### Claim 4 (depends on 1)

The process of claim 1, wherein the pipette tip tray comprises a card component.

### Claim 5 (depends on 1)

The process of claim 1, wherein each of the pipette tips in the pipette tip tray comprises a filter component.

### Claim 6 (depends on 1)

The process of claim 1, which comprises determining an accuracy value for the pipette tips in the manufacturing run.

### Claim 7 (depends on 6)

The process of claim 6, which comprises affixing the accuracy value to the pipette tip tray.

### Claim 8 (depends on 6)

The process of claim 6, which comprises placing the pipette tip tray into a container comprising other pipette tip trays, wherein the pipette tips in the pipette tip trays in the container are from one manufacturing run, and affixing the accuracy value to the container.

### Claim 9 (depends on 1)

The process of claim 1, which comprises determining a precision value for pipette tips in the manufacturing run.

### Claim 10 (depends on 9)

The process of claim 9, wherein the precision value is a coefficient of variation (CV) value.

### Claim 11 (depends on 10)

The process of claim 10, which comprises affixing the CV to the pipette tip tray.

### Claim 12 (depends on 10)

The process of claim 10, which comprises placing the pipette tip tray into a container comprising other pipette tip trays, wherein the pipette tips in the pipette tip trays in the container are from one manufacturing run, and affixing the CV to the container.

### Claim 13

A process for determining a manufacturing run of a component of a pipette tip tray, which comprises:
(a) loading pipette tips into a pipette tip tray comprising a rack and a card affixed to the rack, whereby the pipette tips are mounted in the card, wherein each component in the pipette tip tray is from one manufacturing run;
(b) associating a serial number to the pipette tip tray, wherein the serial number is unique to the manufacturing run of each of the components;
(c) identifying a serial number associated with the pipette tip tray; and
(d) determining the manufacturing run of one of the components of the pipette tip tray from the serial number affixed to the pipette tip tray.

### Claim 14 (depends on 13)

The process of claim 13, wherein the manufacturing run of the pipette tips is determined from the serial number associated with the pipette tip tray.

### Claim 15 (depends on 13)

The process of claim 13, wherein the pipette tip tray component comprises a rack and manufacturing run of the rack is determined from the serial number associated with the pipette tip tray.

### Claim 16 (depends on 13)

The process of claim 13, wherein the manufacturing run of the card is determined from the serial number associated with the pipette tip tray.

### Claim 17 (depends on 13)

The process of claim 13, wherein the rack component comprises a lid.

### Claim 18 (depends on 14)

The process of claim 14, wherein the pipette tips in the pipette tip tray further comprise filter components from one manufacturing run and the manufacturing run of the filter components is determined from the serial number associated with the pipette tip tray.

### Claim 19 (depends on 14)

The process of claim 14, wherein the pipette tip tray is in a container comprising a coefficient of variation (CV) value affixed to the container, which CV value was determined for pipette tips in the manufacturing run.

### Claim 20 (depends on 14)

The process of claim 14, wherein the pipette tip tray comprises a coefficient of variation (CV) value affixed to the tray, which CV value was determined for pipette tips in the manufacturing run.

### Claim 21 (depends on 13)

The process of claim 13, wherein associating a serial number to the pipette tip tray comprises affixing a serial number to the pipette tip tray.
